Prosthetic use of carbon fiber-reinforced epoxy resin for esthetic crowns and fixed partial dentures.

The traditional alloys used as metal bases for fixed partial dentures are accompanied by various problems such as corrosion, allergy, toxicity, casting, and preparation for both patient and prosthodontist and in magnetic resonance imaging for diagnosis. A DGEBA-DDM type polyepoxide resin and carbon fibers composite has been introduced that addresses some of these considerations. A three-part study of the clinical behavior of a limited number of prostheses has shown positive results confirming the biofunctional capacity of polyepoxy-carbon materials and their gingival biocompatibility.

[Gingival preparation].

For the general practitioner, the superficial periodontal structure is an obstacle when trying to gain access, control and visualization to juxta or infra gingival preparations. A temporary restoration will maintain and protect those limits and in many cases it is a very efficient procedure. Sometimes it is necessary to enhance the gingival preparation by sophisticated methods. There are many different technics available to the practitioner. In this article we will describe the technics with easy clinical use and those respecting the gingival tissue (mechanical, physico-chemical).

[Full band impressions].

Complete impression with rings achieves the same definition than complete impressions alone and gives a final quality similar to unitary guided impressions. The required steps are the following: 1st clinical: adjustment of the unitary rings, laboratory: elaboration of metallic resin boxing and individual tray, 2nd clinical: complete impression with rings. This method is of a particular interest because of its facility and its possible adaptations to various impression pastes or clinical situations. No gingival conditioning is required to the impression, and increased indications of the method can thus be seen when esthetics or periodontal conditions are a priority.
