Summary:

Background: Following tooth extraction and immediate implant installation, the edentulous site of the alveolar process undergoes substantial bone modeling and the ridge dimensions are reduced.
Objective: The objective of the present experiment was to determine whether the process of bone modeling following tooth extraction and immediate implant placement was influenced by the placement of a xenogenic graft in the void that occurred between the implant and the walls of the fresh extraction socket.
Material and methods: Five beagle dogs about 1 year old were used. The 4th premolar in both quadrants of the mandible (4P4) were selected and used as experimental sites. The premolars were hemi-sected and the distal roots removed and, subsequently, implants were inserted in the distal sockets. In one side of the jaw, the marginal buccal-approximal void that consistently occurred between the implant and the socket walls was grafted with Bio-Oss Collagen while no grafting was performed in the contra-lateral sites. After 6 months of healing, biopsies from each experimental site were obtained and prepared for histological analyses.
Results: The outline of the marginal hard tissue of the control sites was markedly different from that of the grafted sites. Thus, while the buccal bone crest in the grafted sites was comparatively thick and located at or close to the SLA border, the corresponding crest at the control sites was thinner and located a varying distance below SLA border.
Conclusions: It was demonstrated that the placement of Bio-Oss Collagen in the void between the implant and the buccal-approximal bone walls of fresh extraction sockets modified the process of hard tissue healing, provided additional amounts of hard tissue at the entrance of the previous socket and improved the level of marginal bone-to-implant contact.

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…

Retrospective Evaluation of Crestal Bone Changes Around Implants With Reduced Abutment Diameter Placed Non-Submerged and at Subcrestal Positions: The Effect of Bone Grafting at Implant Placement
One method to measure the success of dental implant treatment is to evaluate marginal peri-implant bone-level changes and stability over time. The location of the fixture–abutment interface (FAI) can be of major importance when the goal is to construct esthetic restorations. In these situations the FAI is often placed in a more apical position to create an ideal emergence profile for the prosthetic construction. However, several animal studies have reported that placement of the FAI in a subcrestal position may result in peri-implant marginal bone loss. The aim of the present study is to evaluate the effect of bone grafting of the defect between the bone crest and the coronal aspect of the implant for implants with reduced abutment diameters placed non-submerged and in subcrestal positions.

The “All on Four" Approach to Implant Dentistry
New surgical and prosthetic protocols may allow the patient and clinical teams with innovative techniques that have been studied using evidence based protocols in private practice. This program is design to help the clinical team understand one of the popular protocols, the All-On-Four Procedure. The presenter of this program will guide the attendees through the pre-treatment planning, surgical, prosthetic, and laboratory procedures. Special emphasis will be given to various biomaterials that can be used for the final fixed prosthesis for patient receiving four implants.

Digital Dentistry in the Management of Simple and Complex Cases: The Digital Intra-Scanner - Part 2
The advent of new technologies has enabled the utilization of new materials and equipment that facilitate the production of restorations with an accuracy that has, up to now, been difficult to obtain reliably. This lecture utilizes patient presentations to help analyze and highlight new systematic clinical protocols that have been developed to optimize the evolving knowledge in digital dentistry and materials. These protocols have allowed us to modify work flow and operational techniques to shorten lead times, while maintaining optimal accuracy. Advantages and disadvantages of the methods outlined will be evaluated and analyzed on the basis of existing literature and personal experience.

Advanced Bone Grafting Techniques: Part 2 - Autogenous Bone Blocks in the Reconstruction of the Atrophic Maxillary Ridge
This lecture will describe the use of autologous onlay block bone grafting for reconstruction of moderate to severe atrophic maxillary alveolar ridge. This will include a discussion of the various options to this form of grafting, such as short implants, maxillary sinus augmentation, sub-nasal elevation procedure, connective tissue grafting and soft tissue manipulation, Le-Fort I down fracture/osteotomy and the use of progenitor cells: bone marrow aspirating concentrated. The Mutli-Tier onlay Bone Graft Technique will be highlighted in this presentation. Additionally, a review of a recently submitted research paper of long term follow up of implants placed into autologous bone blocks harvested from the mandibular ramus, immediate loading by pre-computer-aided/pre-prepared temporary bridge areas will be discussed.
