Epoxy/carbon composite resins in dentistry: mechanical properties related to fiber reinforcements.

Composite carbon/epoxy resin techniques for restorative dentistry have improved with the development of various composite resins classified according to fiber reinforcement, such as short fibers, woven materials, or long unidirectional fibers. This study of the mechanical properties with three-point flexion enabled comparison of the flexural strengths. The modulus of elasticity of different composite resin materials was determined so that the appropriate reinforced composite resin could be selected for specific clinical conditions.

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).

[Reversible hydrocolloids].

Reversible Hydrocolloids impressions are the most simple, easy and reliable of all the available impression technics, when their indications are respected. The precision of this technic, although excellent, can not render this technic universal. The indications and limitations of this technic are directly related to the properties of the reversible hydrocolloids. Good clinical results will depend on: a very good gingival retraction technic (with enough space for the material) and the immediate casting of the impression; the knowledge of the intrinsic qualities and performances of the material during all the clinical steps, without trying to surpass or betray those qualities.
