Resumo
This case report presents the principles, techniques (laboratory
and clinical) and the results of an oral rehabilitation with a
glass fiber–reinforced composite fixed partial denture (GFCPD).
A 23-year-old female patient with absence of tooth 36, intact 35
and 37 with class I amalgam restoration came to dental school.
Expulsive OD and MO conservative cavity preparations were
executed on teeth 35 and 37, respectively. Definitive impressions
were taken with a condensation silicone and provisional
restorations made with acrylic resin. The glass-fiber system plus
the microhybrid composite resin, in colors A3 e A2 (enamel and
dentin), were employed. After finishing and polishing the prosthesis,
intaglio surfaces were aluminum oxide sandblasted, silanized
and adhesively fixed with Adper Single Bond 2 and Rely-X
ARC. Then, a rigorous occlusal adjustment and new polishment
were performed with diamond pastes. This conservative treatment
option enabled tooth 35 to receive minor cavity preparations
and also tooth 37, which had already been prepared in the
past to receive an amalgam restoration. The employed materials
restored occlusal function and esthetical appearance, and occlusal adjustment rises the chances for greater longevity. The knowledgement
about GFCPD cavity preparation principles, fibers
issues, prosthodontics planning and adhesive principles are the
principal reason for successful treatments.
