Bone Grafting of Previously Used Symphysial Donor Sites for Onlay of Newly Formed Bone and Reharvesting Potential Symphysis Revisited:Clinical and Histologic Evaluation
Placement of an endosseous implant requires sufficient bone volume for complete bone coverage. The use of intraoral block bone grafts from intraoral sources has increased over the years. Possible sources for autogenic bone are the calvarium ,tibia,and the iliac crest(frequently used for major jaw reconstruction).However,these sources are not always recommended because of their morbidity,altered ambulation,and the need for hospitalization,as well as significant resorption associated with corticocancellous block grafts from endochondral donor sites.

Radiological Findings of the Post-Sinus Lift Maxillary Sinus: A Computerized Tomography Follow-Up
The purpose of this article is to present radiological findings of a short-term (8 to 10 months) computerized tomography (CT) follow-up study on 1-stage maxillary sinus lift cases.

Cortical Tenting Grafting Technique in the Severely Atrophic Alveolar Ridge for Implant Site Preparation
Tenting of the periosteum and soft tissue matrix using a cortical bone block maintains space and minimizes resorption of the particulate allograft volume. In addition,bridging the cortical blocks with particulate bone avoids unaesthetic ridge defects between cortical block grafts in larger ridge defects. The result was a more uniform and esthetic alveolar ridge, capable of maintaining an implant-supported prosthesis. The technique offers predictable functional and esthetic reconstruction of large volume defects without extensive amounts of autogenous bone. This of- fers a superior functional and esthetic result than with either cortical or particulate grafting alone.

The Bio-Derm Ridge Plumping Technique for Pontic Site Development
Seibert Class III apicocoronal and buccolingual alveolar ridge defects with associated gingival mucosal atrophy and absence of interdental papillae are common in edentulous areas within the anterior esthetic zone of the maxilla. Normal emergence profiles, critical to achieving esthetic restorations, require restoration of normal hard and soft tissue morphology, including re-establishment of adjacent interdental papillae.

Introducing Choukroun’s Platelet Rich Fibrin (PRF) to the Reconstructive Surgery Milieu
Platelet-rich fibrin (PRF), developed in France by Choukroun et al (2001), is a second generation platelet concentrate widely used to accelerate soft and hard tissue healing. Its advantages over the better known platelet-rich plasma (PRP) include ease of preparation/application, minimal expense, and lack of biochemical modification (no bovine thrombin or anticoagulant is required). PRF is a strictly autologous fibrin matrix containing a large quantity of platelet and leukocyte cytokines. This article serves as an introduction to the PRF “concept” and its potential clinical applications.

Suture Selection for Optimal Flap Closure and Tissue Healing
Suture selection is based on a knowledge of the physi cal and biologic characteristics of the suture thread in relationship to the healing process. In addition, accurate apposition of the flap is significant to patient comfort, hemostasis, reduction of the wound to be repaired, and prevention of unnecessary bone destruction. If flaps are not approximated and inadequate hemostasis is present, blood and serum may accumulate under the flap, delaying the healing process by separating the flap from the…

Computer-Generated Abutment Using A Coded Healing Abutment: A Two-Year Preliminary Report
This article presents a preliminary clinical evaluation following the placement of 107 dental implants covered with computer-coded healing abutments. The healing abutment system evaluated herein provided information to specific computer software that facilitated the delivery of an anatomical definitive abutment. This system also assisted in the development of a titanium abutment whose characteristics mimicked the natural contours of the teeth being replaced. A two-year postoperative evaluation was performed to evaluate occlusion, gingival integrity, contact areas, inflammation, food impaction, porcelain integrity, radiographic condition and overall patient satisfaction. Improved tissue response and resultant aesthetics were observed.

Dental Implants: Mastering Esthetics in the Smile Zone
The key to contemporary restorative dentistry is the fabrication of healthy, maintainable, esthetic, and functional prostheses. The true success of any restoration is reliant on the creation of an “illusion of reality,” regardless of the restorative modality used (eg, porcelain laminate veneers, crowns, and/or implant-supported prostheses). Developments and advances to the restorative armamentarium have significantly improved the clinician’s ability to deliver predictable and reliable treatments. Osseointegration…

Soft Tissue Recession Around Implants
When treatment with dental implants is indicated, an accurate diagnosis must be made to evaluate the clinical parameters and determine the optimal time for immediate or delayed (ie, early or late) implant placement and loading following tooth extraction. It is also important to identify complications and their implications on the aesthetic outcome.1 This article explains behavior of the hard and soft tissue around the implant, evaluates the timing of implant placement after extraction, and reviews various parameters that influence tissue marginal remodeling.

Soft Tissue Recession Around Implants 2
Implant therapy is a predictable method of replacing lost teeth and involves consideration of numerous surgical and restorative criteria. Part I of this article explained the behavior of the hard and soft tissue around the implant and reviewed various parameters that influence tissue remodeling. Part II emphasizes surgical factors (eg, tridimensional implant placement, platelet-rich fibrin, and the use of connective tissue grafts) and restorative factors as means of limiting soft tissue recession around implants.

CT-Derived Model-Based Surgery for Immediate Loading of Maxillary Anterior Implants
A novel approach to predict implant placement utilizing CT-derived model-based surgery was performed for a maxillary-anterior aesthetic immediate extraction/immediate restoration; root proximity and inter-implant positioning was an additional complication. The use of state-of-the-art diagnostic and treatmentplanning tools described in this article has been shown to be effective for both partial and completely edentulous patient presentations. These tools can serve as a foundation for accurate, highly practical, and repeatable CT-scan–derived modelbased presurgical prosthetic planning for the immediate loading of dental implants.

Timing, Positioning, & Sequential Staging in Esthetic Implant Therapy

An electronic search of databases was performed, in addition to a hand search of the most relevant journals. All relevant articles were independently screened…

Implant Site Preparation with Motorized Bone Expanders
The osteotome technique has been utilized for many years as a viable approach to expand atrophic ridges. Despite its effectiveness, the mechanical impact from the surgical mallet is not well tolerated by patients. Additionally, reports in the literature describe postoperative complications that include concussions and benign paroxysmal vertigo. These conditions can be alarming for the patient and clinician, as their effects may persist for several weeks. A new technique for atraumatic ridge expansion…

Techniques for the Use of CT Imaging for the Fabrication of Surgical Guides
Implant dentistry has evolved into one of the most predictable treatment alternatives for partially and completely edentulous patients. The initial excitement about successful osseointegration has allowed clinicians to offer an extended set of treatment alternatives that include single tooth replacement to full mouth reconstruction. Pioneering protocols of the early 1980s relied on a two-stage surgical approach that allowed for the biological aspects of osseointegration to be achieved at the cellular level, insuring long-term success. These procedures often required extended periods of time to complete. Through strategic marketing and word of mouth, demand for implant-related treatment continues to grow and has compelled clinicians to search for new and improved methods to deliver such care within a shorter time period without sacrificing accuracy. As treatment protocols have progressed...

Prosthetic Management of Implants with Different Osseous Levels
The osseointegrated implant has become a standard treatment with a high degree of predictability for patients missing one or more teeth. It is especially recommended when the patient has a clear medical history and normal bone levels in both width and height in the edentulous areas. In constant search for improvement, clinicians find themselves looking into every element relating to the replacement of a missing tooth or teeth: existing bone structure, surgical technique, implant placement, implant…

Facial Development, Continuous Tooth Eruption, and Mesial Drift as Compromising Factors for Implant Placement
The replacement of teeth lost by children because of trauma can be an important indication for early implant therapy. Osseointegrated dental implants, like ankylosed teeth, alter position as growth-related changes occur within the jawbones (displacement, remodeling, mesial drift). Facial growth of the child and even of the adolescent, as well as the continuous eruption of the adjacent anterior teeth, create significant risk of a less favorable esthetic and/or functional outcome. For patients with…

Implant Therapy-Sequence of Surgical & Restorative Phases
Failure of the natural dentition due to periodontal- or endodontic-related osseous infections may complicate implant therapy. Sequencing (ie, staging) of the surgical aspects of the treatment is essential to achieve the desired restorative objectives. Additionally, for indications in which the adjacent natural teeth require cosmetic enhancement as part of the overall treatment plan, proper sequencing will influence the definitive results. The following article discusses the surgical and restorative…

To shorten the length of treatment associated with the Brånemark protocol, as well as to preserve soft and hard tissues, newer protocols have focused on reducing or even eliminating the time between tooth extraction and implant placement and between implant placement and prosthetic restoration delivery. The authors present a case in which control of postextraction implant placement, optimal implant…

Immediate Loading of Osseotitie Implants-After 4 months
A growing number of clinical reports show that early and immediate loading of endosseous implants may lead to predictable osseointegration; however, these studies provide mostly short- to mid-term results based only on clinical mobility and radiographic observation. Other methods are needed to detect the possible presence of a thin fibrous interposition of tissue that could increase in the course of time and lead to clinical mobility. A histologic evaluation was performed on two immediately loaded…

Workshop Guidelines on Immediate Loading in Implant Dentistry
Predictable formation of a direct bone-to implant interface is a treatment goal in implant dentistry. The 2-stage surgical protocol established by Branemark et al to accomplish osseointegration consisted of several prerequisites, including (1) countersinking the implant below the crestal bone, (2) obtaining and maintaining a soft-tissue covering over the implant for 3 to 6 months, and (3) maintaining a minimally loaded implant environment for 3 to 6 months. The primary reasons cited for the submerged,…

Advances in the surgical and prosthetic components, implant designs and surface technologies, and imaging techniques have allowed for significant modifications to occur with respect to one- and two-stage surgical protocols, accelerating treatment times to the benefit of patient and clinician. This article presents a technique to improve surgical and restorative accuracy, allowing for predictable placement and immediate loading of implants through use of CT imaging, stereolithographic models, and CT-derived surgical templates.

Flapless Immediate Adjacent Implants and Provisionalisation
Fourth part in a series discussing a biologically driven approach to aesthetics.

Vertical Distance from the Crest of Bone to the Height of the Interproximal Papilla Between Adjacent Implants
As patient demand increases for more natural restorations in the esthetic zone, clinicians must have the highest level of skill and knowledge to maintain or reform the interdental papilla between teeth, between implants and teeth, and between adjacent implants. To date, there are no reports that have measured the distance from the contact point to the bony crest between implants. One reason for this may be the fact that, with two adjacent implants, the contact point of the crown can be established at any distance from the gingival margin according to the restorative dentist's specifications. Therefore, in this study, the height of the soft tissue to the crest of bone was measured between two adjacent implants independent of the location of the contact point. The purpose of this study was to determine the range and average height of tissue between two adjacent implants.

Immediate Total Tooth Replacement
Cutting edge implant procedures are described in detail.

CT Scan Technology
Implant dentistry, one of the most predictable treatment alternatives offered to patients who are missing teeth can be enhanced by thorough pre-surgical diagnosis and treatment planning efforts by all members of the implant team. Conventional radiologic techniques including periapical and panoramic radiographs are limited by the two dimensional interpretation of existing hard and soft tissue. The inherent distortion factor can misrepresent bone topography in critical areas associated with vital anatomy or potential implant sites. Advances in diagnostic radiological techniques improved with the introduction of CT scan technology for dental applications. The enhanced diagnostic range of this evolving technology empowers the clinician with necessary tools to avoid potential complications associated with implant dentistry.

Aesthetic Enhancement of Anterior Dental Implants with the Use of Tapered Osteotomes & Soft Tissue Manipluation
An adequate bone base is usually a prerequisite for functionally and aesthetically optimal reconstruction of the soft tissue architecture around a dental implant.

Aesthetic Enhancement of Anterior Dental Implants with the Use of Tapered Osteotomes and Soft Tissue Manipulation
As osseointegration of endosseous dental implants has become predictable and well-documented, the emphasis in dental- implant treatment has shifted from functional concerns to the achievement of long-term aesthetic results. An adequate alveolar bone base is the prerequisite for functional and aesthetically optimal reconstruction of the soft-tissue architecture. This is true for both fixed partial denture (FPD) pontic sites and dental implant sites. In patients with sufficient bone height but insufficient bone…

Replacement of a Mutilated Maxillary Incisor With a Single Implant Restoration: A Staged Implant
Patients are advised to maintain oral health in order to enjoy function and the natural appearance of their dentition for a lifetime. In the event that oral health becomes impaired, clinicians are capable of restoring it through either conservative or sophisticated treatment modalities. This treatment must be based on sound, rationalized clinical evidence and a clear understanding of the biological and physiological processes involved. Dental professionals must also acknowledge their personal limitations…

Periodontally Considerations of Dental Implantology
<p>The endosseous dental implant has steadily progressed to become an important modality of restoring incomplete dentitions in either fully or partially edentulous patients. Osseointegrated dental implants have demonstrated relatively high success rates in both the maxillary and the mandibular jaws. The American Academy of Implant Dentistry (AAID), the American Dental Association (ADA), and numerous other professional organizations have endorsed the placement of osseointegrated dental implants as…

Fifty Years of Interdisciplinary Site Development: Lessons & Guidelines from Periodontal Prosthesis
Just as "osseointegration" became synonymous with successful restoration of function in the fully edentulous patient during the 1980s, the term "implant site development" has become intricately associated in the 1990s with the techniques used to achieve esthetic results with implants in the partially edentulous patient. This article explores the roots of the concept of site development within the philosophy and principles of periodontal prosthesis. In addition, the myriad of techniques that are…

Prosthodontics, Periodontics & Orthodontics: A Multidisciplinary Approach to Implant Dentistry
Many aspects of various dental disciplines must be integrated to constitute a sound total approach to implant dentistry. Aside from the surgical elements - encompassing implant placement, position, angulation, and length - the creation of appropriate spaces to accommodate the three-dimensional final prostheses may require use of orthodontic techniques as well. And establishing and maintaining a sound periodontal environment is essential to implant integrity, from the outset of placement to finalization of the prosthetic suprastructure.

Restoration Implant Placement & Site Development
In any restoration or natural tooth, the surrounding soft-tissue profile plays an integral role in the final esthetics of a case. Similarly in implant restorations, it is no longer sufficient to merely attach a prosthetic device to the underlying fixture, but for optimal esthetics it has become essential for the implant site to be reconstituted in a three-dimensional approach. This invariably involves redevelopment or replacement of lost hard tissue and redevelopment of the correct soft-tissue profile,…

Immediate Loading of Bilaterally Splinted Titanium Root-Form Implants in Fixed Prosthodontics
A load-free healing period has been advocated as a prerequisite to achieving osseointegration. This article reports two cases in which immediate loading of a specially designated additional or "expendable" set of titanium root-form implants was successfully utilized to support provisional fixed restorations in the maxilla and the mandible. This immediate-loading protocol is suggested as a reliable adjunctive therapeutic modality for offering implant patients access to fixed interim restorations…

Nifedipine-induced Gingival Enlargemenr Around Dental Implants
Calcium channel-blocking agents are used extensively for the management of cardiovascular conditions, including angina pectoris, coronary artery spasm, cardiac arrhythmias, and hypertension.

Linear Tomography in Conjuction with Pantomography in Implant Assessmnet Sites
Tomography provides a three-dimensional unobstructed and anatomically accurate picture of the region being viewed. Tomography is a radiographic technique in which a "slice" or section of a given internal body structure is imaged in a pre-determined plane. The advantage of utilizing a tomographic evaluation along with a pan tomographic survey is that the clinician may examine the exact position or depth in all three planes of visualization. This radiographic modality can also reveal the quality and…

Osseointegrated Titanium Implants for Maxillofacial Protraction in Monkeys
Titanium implants were placed surgically into the maxillary, zygomatic, frontal, and occipital bones of four pigtail monkeys. After a 4-month healing period, the implants were exposed and abutments were placed. Extraoral traction appliances were then attached to the abutments. The cranial implants were used to support the framework of the traction appliance; those in the facial bones were used to attach springs that delivered a protraction force. The application of force varied among animals. In animal…

Root Fracture During Insertion of Prefabricated Posts
The consequence of inappropriate post selection and/ or hasty insertion can result in tooth fracture and/or loss. It has been demonstrated that conical or parallel sided post design has a direct effect on root fracture during post insertion. However, during experimentation it became apparent that root size and its relationship to post size had a direct effect on root fracture. This article correlates root size, post size, and fracture rate during insertion of prefabricated posts.

Instrumentation for Modern Day Implant Surgery
Public awareness of the aesthetic possibilities through the replacement of missing or nonsalvageable teeth has been elevated with advances in dental implant therapy and related hard and soft tissue regenerative therapies. This has led to an increase in the fabrication of fixed prostheses supported by either natural teeth, dental implants, or removable prostheses anchored by implants rather than conventional tissue- or tooth-supported partial dentures.

Optimum Esthetics and Rentention with Cast-to Abutments
Progress and technological evolution is something we should all embrace since such attributes allow us to provide patients with improved care. But when is it appropriate to consider proven materials and techniques outdated and when should one move forward with the promise of better product(s) along with superior outcomes?

A New Implant Design for Crestal Bone Preservation: Initial Observations and Case Report
Following the exposure and restoration of two-piece dental implants, some change in the vertical level of the peri-implant crestal bone height has been reported. This change in crestal bone height has not, however, negatively impacted long-term implant success. This article describes how the concept of platform switching is incorporated into a new implant design as a means of reducing or eliminating the occurrence of crestal bone loss. Preliminary observations from clinicians utilizing this new implant design are herein presented.

A significant no-load healing period is the generally accepted prerequisite for osseointegration in dental implantology. The aim of this article was to examine whether this no-load healing period is validated by the experimental literature. In vivo histological data was scrutinized to identify the effect of early loading protocols on the bone-implant interface. Several loading modes were identified. They were categorized into groups according to implant design and the type of prosthetic reconstruction,…

Socket Preservation to Gain
Tooth loss not only poses difficulty in mastication, it also involves the probable resorption of alveolar bone due to a loss of function and stimulation from the periodontal ligament fibers (PDL). Bone grafting at the time of tooth removal provides bone quantity and quality for future placement of dental implant(s). The challenge during this procedure—referred to as socket preservation—is maintaining the graft in place as well as providing a final working area with sufficient keratinized tissue…

Immediate Occlusal Loading the Same Day or Day After Implant Placement
Immediate loading of endosseous implants is becoming a widespread therapeutic procedure for the rehabilitation of patients with edentulous jaws. The purpose of this prospective clinical trial was to evaluate the long-term success rate of endosseous implants placed in the edentulous lower jaw and loaded on either the same day of surgery or the next day. Nineteen patients were enrolled in the study. Eleven patients, accounting for 64 implants, received their provisional prosthesis the same day of…

Comprehensive Management of Implant Anchorage in the Multidisciplinary Patient
In recent years, dental implants have become an accepted method of replacing missing teeth. Today millions of implants are placed annually to rehabilitate and reestablish patients’ occlusions. However, in many of these individuals, the teeth may be in less than ideal position to accept the integration of single implants or groups of implants with the remaining teeth. Many of these patients could benefit from orthodontics to reposition malposed teeth to enhance the overall occlusal scheme. However,…

Determining the Cessation of Vertical Growth of the Craniofacial Structures to Facilitate Placement of Single-Tooth Implants
<b>Introduction:</b> Single-tooth implants are commonly used to replace congenitally missing teeth in adolescent orthodontic patients. However, if implants are placed before cessation of facial growth, they will submerge relative to the adjacent erupting teeth. Therefore, it is important to know when facial growth is complete in postpubertal orthodontic patients. The purposes of this study were to determine and quantify the amount of vertical growth of the facial skeleton and the amount of eruption…

Treatment Planning 2000: An Esthetically Oriented Revision of the Original Implant Protocol
The purpose of this article is to outline the blueprint for a comprehensive multidisciplinary treatment philosophy, designed for developing the foundation for optimal esthetics in implant therapy. In addition, the important synergistic relation of the osseous, gingival, and restorative triad in creating the esthetic profile is described. The need to enhance the individual components of this triad is emphasized as the basis for a revised implant protocol actualized for treating the complex partially…

Immediate Occlusal Loading (IOL) of Dental Implants: Predictable Results Through DIEM Guidelines
In recent years, the immediate loading of dental implants has become more accepted as a standard protocol for the treatment of the fully edentulous mandible. The pioneers in implant dentistry often tried this technique but only achieved mixed success. One of the main reasons for the failure of these early attempts was the lack of understanding of the biological and mechanical principles that we now know are necessary for clinical success.

Advantages of the Root Submergence Technique for Pontic Site Development in Esthetic Implant Therapy
This article suggests a strategy to provide a more predictable protocol for esthetic implant treatment for multiple- tooth defects using the root submergence technique (RST). The RST maintains the natural attachment apparatus of the tooth in the pontic site, which in turn allows for complete preservation of the alveolar bone frame and assists in the creation of an esthetic result in adjacent multipletooth- replacement cases.
