Interpositional Bone Grafts to Treat the Posterior Atrophic Mandible Premium Member Content

Interpositional Bone Grafts to Treat the Posterior Atrophic Mandible
This presentation analyzes the interpositional bone graft or inlay technique, discussing the reconstructive surgical approach. Horizontal osteotomy with the interposition of bone in the form of a “sandwich” involves raising a coronal osteotomized segment of the mandible, which is still attached to the lingual periosteum, and interpositioning a block bone graft. This technique guarantees a dual vascular supply to the inlay graft from the lingual periosteum and from the residual bone; it also allows optimum use of the native basal bone, which should be less prone to resorption. The advantages and disadvantages of the inlay technique are compared with other commonly used augmentation techniques in the management of posterior mandibular atrophies.

Achieving Stable Esthetic Results with Implant Supported Restorations Premium Member Content

Achieving Stable Esthetic Results with Implant Supported Restorations
We will discuss basic concept regarding immediate implant placement and guided bone regeneration procedure related to the esthetic zone before focusing on the soft tissue management. We will describe the prosthetic procedures which are performed before, during and after the surgical procedures. Provisional restorations, impression techniques, prosthetic profiles and restorative materials will be presented. The purpose of the presentation is to provide a check list that will guide the clinician developing a proper analysis and diagnosis for the successful esthetic result with implant supported restoration.

Predictable Posterior Implant Placement in Extraction Sites Premium Member Content

Predictable Posterior Implant Placement in Extraction Sites
Many techniques have been published to preserve the ridge from buccal-lingual collapse. In this presentation, we will overview the literature and see some cases to explain which is one of the most predictable protocols for immediate extraction and immediate implant placement in posterior areas according to the latest studies. We will also show the benefits of using growth factors as an agglutinant and protective component for our graft in non cooperative patients.

Periodontal-Prosthesis in Modern Dentistry – Part 1 of 2 Premium Member Content

Periodontal-Prosthesis in Modern Dentistry – Part 1 of 2
Clinicians must be aware of patient expectations when planning dental treatment. When full mouth reconstruction is planned, it is very important to satisfy such expectations in order to provide successful treatment. Patients are often concerned about the cost and duration of treatment, and the pain, esthetics, comfort, and function after treatment. However, we cannot assure longevity unless the treatment has a scientific basis. During reconstruction or restoration, we generally remove and replace the existing crowns. Secondary caries are mostly detected on removal of these. Due to the caries, the ferrule and tooth thickness are not adequate; and frequently, the condition may not be suitable for prosthetic treatment. In such cases, we choose to extract the tooth or perform crown lengthening to retain the tooth.Thse days many teeth that we could retain by crown lengthening procedure are replaced by implants. In this presentation, we describe some cases in which a crown lengthening proce

Antimicrobial Effect of a Single Dose of Amoxicillin on the Oral Microbiota

Antimicrobial Effect of a Single Dose of Amoxicillin on the Oral Microbiota
Amoxicillin is commonly used in oral surgery for antimicrobial prophylaxis against surgical-site infection and bacteremia because of its effect on oral streptococci. The aim of this study was to determine whether amoxicillin reaches the break-point concentrations in saliva and has any effect on the salivary microbiota, colonizing bacteria on mucosal membranes and on the gingival crevice after a single dose of amoxicillin. A single dose given as prophylaxis to prevent a surgical-site infection results in a significant reducing effect on the oral streptococcal microflora in the gingival crevice and may have an impact on bacteria spreading into tissues and the bacteria of streptococci.

Reconstruction of a Single-Tooth Traumatic Defect in the Anterior Maxilla Using the Khoury Bone Plate Graft

Reconstruction of a Single-Tooth Traumatic Defect in the Anterior Maxilla Using the Khoury Bone Plate Graft
Trauma to teeth and the dentoalveolar process may result in a ridge defect that precludes straightforward implant therapy of the patient. Typically bone and soft tissue augmentation of the area would first be needed to adequately prepare the tissues for the implant and its restoration..Grafting of the site is substantially more difficult in cases where the ridge also lacks adequate height, and techniques to recreate a bony envelope to apply guided bone regeneration may be required. Moreover, defects in the anterior aesthetic zone that require both bone and soft tissue grafting and a restoration that harmonizes the adjacent pink and white aesthetics may be an even more significant challenge to the restorative team. Hereafter a case of trauma to an anterior maxillary tooth that saw destruction of the ridge is presented, with the defect reconstructed to accommodate a functional and aesthetically pleasing implant supported restoration.

The Pontic-Shield: Partial Extraction Therapy for Implant Dentistry

The Pontic-Shield: Partial Extraction Therapy for Implant Dentistry
Augmentive ridge preservation techniques aim to manage the postextraction ridge. The partial extraction of teeth may better preserve the ridge form by maintaining the bundle bone-periodontal tissues and preserve the ridge beneath dentures or fixed prostheses. The socket-shield technique entails preparing a tooth root section simultaneous to immediate implant placement and has demonstrated histologic and clinical results contributory to esthetic implant treatment. A retrospective 10-patient case series treating 14 partial extraction sites demonstrates how a modification of the socket-shield technique can successfully develop pontic sites and preserve the ridge.

Immediate Implant Placement into Extraction Sockets with Labial Plate Dehiscence Defects: A Clinical Case Series

Immediate Implant Placement into Extraction Sockets with Labial Plate Dehiscence Defects: A Clinical Case Series
To measure the buccal plate reconstruction of extraction sockets with labial plate dehiscence defects using a bone allograft in combination with an absorbable collagen membrane and a custom-healing abutment at the time of tooth removal. Implants placed into sockets with labial plate dehiscence defects demonstrated radiographic reformation of the labial plate dehiscence defect at 6 to 9 months post-treatment. The net gain in labial plate on CBCT in L1 and L2 was 3.0 mm, where 0 mm existed at pre-treatment. The minimum amount of labial plate thickness of 2.0 mm was achieved in all treated sites, evaluated radiographically at 6-9 months post-operatively, in a single procedure, without flap elevation and maintaining the gingival architecture and satisfactory esthetics.

Vertical or Shoulderless Preparations in Contemporary Prosthodontics Premium Member Content

Vertical or Shoulderless Preparations in Contemporary Prosthodontics
Tooth preparations without a defined finish line have been termed in several different ways, such as knife edge, feather edge, or shoulderless. From a biological standpoint, preserving a maximum amount of sound tooth structure, as it is done in vertical preparations, might also offer a more conservative alternative to a horizontal margin design in other clinical conditions such as endodontically treated teeth, vital teeth in young individual, teeth affected by caries at the cervical third. Vertical margins on zirconia crowns have been tested in vitro and clinical reports have been published. A re-evaluation of possible advantages and shortcomings of vertical preparation design in contemporary prosthodontics will be presented in light of recently published literature.

Bone Reconstruction: A New Algorithm for the Implantologist Premium Member Content

Bone Reconstruction: A New Algorithm for the Implantologist
Bone augmentation is often required to place an adequate number of dental implants in ideal positions for prosthetic support. In addition to biomechanical demands bone augmentation can also provide proper ridge contour for improved esthetic outcomes. Disadvantages of bone augmentation techniques include increase morbidity, surgical time, costs and treatment length. As such a trend has develop towards treatment approaches that avoid bone grafting including shorter and narrower implants, angled implants and/or fewer implants for prosthetic support. This presentation will look at various bone augmentation techniques, methods to minimize the morbidity of bone grafting and guide clinicians on implant rehabilitation with grafting versus non-grafting approaches.
