ABSTRACT
This study evaluated the fit between implants and premachined and castable UCLA abutments. All plastic specimens were cast using the conventional technique in accordance with the manufacturer's instructions. Five specimens of each experimental group were measured for vertical and horizontal gaps by scanning electronic microscopy (Phillips XL 30 model, Holland). Gold UCLA (vertical gap 2.15 μm, horizontal gap 11.30 μm) and castable rotational UCLA (vertical gap 14.91 μm, horizontal gap 59.41 μm) groups showed the lowest and highest mean values, respectively (Neodent, Curitiba, Parana, Brazil). In general, the castable UCLA abutments showed poorer marginal fit than the premachined abutments.
RESUMO
Esse estudo avaliou a adaptacao entre implantes pilares UCLA usinados e fundidos. Todos os corpos de prova de plastico foram fundidos usando tecnica de fundicao convencional de acordo com o fabricante. Cinco corpos de prova foram avaliados em relacao a desadaptacao vertical e horizontal utilizando um Microscopio Eletronico de Varredura. Os grupos UCLA Ouro (desadaptacao vertical 2.15 μm, horizontal 11.30 μm) e UCLA rotacional fundido (desadaptacao vertical 14.91 μm, horizontal 59.41 μm) mostraram as medias mais baixas e mais altas, respectivamente. De uma maneira geral, os pilares UCLA fundidos mostraram adaptacao menor do que os pilares UCLA usinados.
