Summary:

Precise fit between dental implants and the superstructure is important for the long term success of implants and implant-supported prostheses. One factor which may influence the accuracy of the definitive prosthesis is the stability of the impression coping in polymerized impression material. In some circumstances, an implant must be placed well below the gingival margin, meaning that most of the impression coping will also be situated subgingivally with no contact with the impression material. This can result in reduced stability of the impression coping, allowing it to rotate when fastening the implant analog. This article describes a simple technique that involves the use of a roll of composite resin, tray adhesive, and a small amount of occlusal registration material applied around a transfer coping in a direct implant impression.

Prosthetic Considerations with Periodontal Root Resective Therapy Part 1
Previousiy, the presence of a probable furcation with in a multi rooted tooth was considered an indication for extraction. Loss of attachment in the furcation has traditionally been described as classes I, II , or [ II, depending on the extent of horizontal penetration into the furcation. Tamow and Fletcher subsequently included a vertical component classification with its horizontal counterpart. Interestingly, both of these classifications are based only on periodontal probing depths rather than…

Introducing Choukroun’s Platelet Rich Fibrin (PRF) to the Reconstructive Surgery Milieu

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.

Dental color matching instruments and systems. Review of clinical and research aspects

Dental color matching instruments and systems. Review of clinical and research aspects
Today’s shade-matching technologies have been developed in an effort to increase the success of color matching, communication, reproduction and verification in clinical dentistry, and, ultimately, to increase the efficiency of esthetic restorative work within any practice. The aim of this paper is to provide a comprehensive review of the current state of shade-matching technologies and instrumentation, and their clinical and research application.

The Proof is in the Laboratory; A Maxillary Full Arch Implant Supported Zirconia Prettau Comparison
The FP-3 “Implant Supported Hybrid" has proven to be an exceptional and highly specialized treatment option for patients with non restorable teeth or existing edentulism. The use of zirconia provides the ultimate outcome bringing with it a new standard of esthetics, function and, when done well, a long lasting prosthesis. This presentation will stress the importance of treatment planning, CAD CAM technology, and the all important need for the laboratory technician’s human touch. Surgical aspects, provisonalization during healing, and management of soft tissue are important components. The protocol for final fabrication of the FP-3 all zirconia prosthesis is detailed along with a description of this exciting new technology.

Non-Surgical Periodontal Therapy: Decision Making in the 21st Century
Non-surgical periodontal therapy is a vital part of everyday dental practice. Since the majority of periodontal therapy is performed by general dentists and dental hygienists, it is critical that clinicians have all of the requisite skills and information needed to perform these services at the highest level possible. The purpose of this presentation is to provide the latest evidence- and practice- based information on periodontal debridement and adjunctive therapies that can improve patient outcomes. Though surgical procedures may still need to be performed in some sites, the majority of inflammatory periodontal disease can be eliminated or reduced significantly using the techniques and protocols discussed in this educational segment on non-surgical periodontal therapy.
