A predoctoral honors program in prosthodontics.

Over the last 25 years, the advent of new disciplines in dental education and the increasing body of knowledge in various dental specialties have led to a struggle for curriculum hours within many dental schools. At the same time, the amount of time available for teaching clinical skills in dental schools has not increased appreciably, and fewer patients require (or can afford) sophisticated prosthodontic treatment. As a result of these trends, there has been a general decline in the depth and range of clinical skills of recent dental school graduates, particularly in prosthodontics. New York University College of Dentistry has attempted to address this problem by establishing a predoctoral honors program in prosthodontics.

Maintaining and enhancing gingival architecture in fixed prosthodontics.

The long-term success of fixed prosthodontic restorations is greatly dependent upon the health and stability of the surrounding periodontal structures. This article deals with the interrelationship between fixed prosthodontic procedures and the stability and health of the periodontium. The commonly encountered problem of alterations in gingival architecture is examined in relation to tooth preparation as well as soft tissue preparation. In addition, the ability of the provisional restoration to guide soft tissue form is discussed as well as the role of the final restoration in providing long-term tissue maintenance. Key factors such as margin placement, tissue damage during tooth preparation, the role of the provisional restoration, tissue injury during impression procedures, crown contour, pontic design, and embrasure design are covered in detail.

Tensile strength analysis of midpontic soldering.

A total of 120 three-unit fixed partial dentures were made by using a latex mold to produce uniform wax patterns. Four groups were used to compare the tensile strength of connectors with interproximal solder, midpontic vertical solder, midpontic diagonal solder, and a control of one-piece castings. Three different metals were tested and the tensile load required to fracture the samples as well as the fracture sites were recorded. The following was found: Soldering the interproximal connector area produced the weakest solder joints, regardless of metal tested, at p less than .001. There was no significant difference in the fracture loads between midpontic vertical soldering and midpontic diagonal soldering with all three metals at p less than .01. There was no significant difference in fracture loads between midpontic soldering and unit casting with all three metals at p less than .01. The extreme variations in fracture loads when soldering nickel-chrome-beryllium confirms the technique sensitivity of presoldering this alloy.

Splinting.

The definitions of splinting, occlusal trauma, and mobility have been described. The history of splinting as a treatment for periodontal disease has been noted along with the current concepts of the indications and rationale for splinting. Splints have been classified according to their expected length of service: short-term splints, provisional splints, and long-term splints. The disadvantages of splinting have been enumerated, and examples of the various types of splints currently employed have been demonstrated.
