RECONSTRUÇÃO DE DENTES SEVERAMENTE DESTRUÍDOS COM PINO DE FIBRA DE VIDRO / Reconstruction of severely destroyed Teeth with glass fiber pin

O restabelecimento da forma, função e estética de dentes anteriores com extensa destruição coronária é um grande desafio para a Odontologia. Nesses casos, a utilização de pinos intraradiculares de fibra de vidro, associada a restaurações de resina composta é uma opção viável, que apresenta bom resultado estético, além de ser uma solução rápida, pois dispensa a etapa laboratorial, sem apresentar custo elevado. Este artigo apresenta relato de caso clínico com a utilização desse material. O procedimento foi realizado com o intuito de gerar retenção ao material restaurador definitivo e reforçar a porção coronária remanescente do elemento dentário, minimizando, assim, a probabilidade de fratura.

The restoration of form, function and aesthetics of anterior teeth with extensive coronal destruction is a major challenge in dentistry. In such cases, the use of intra-radicular fiberglass retainers associated with composite restorations is a viable option, which has good aesthetic result, in addition to being a quick solution, because it eliminates the laboratory step without presenting high cost. This article presents a case report with the use of this material. The procedure was performed in order to generate the definitive restorative material retaining and reinforcing the remaining coronal portion of the tooth, thus minimizing the likelihood of fracture.

Anthropometric measurements in toothed and toothless maxillaries and its consequences in human alveolar bone resorption / Mediciones antropométricas en maxilares con y sin dientes de humanos y sus consecuencias en la reabsorción ósea alveolar

This study proposes to measure and compare anthropometric measurements between toothed and toothless maxillas. 26 human skulls were used with: 13 toothed and 13 toothless maxillas. The measurements were made between the distances of the alveolar ridge (AR): the anterior nasal spine (ANS), to the incisive foramen (FI) and the palatine foramen, greater (FPMA) and lower (FPME) on both sides by two evaluators. The data obtained showed that the average of the measurements were correspondingly higher in toothed maxillas than in toothless, for all measurements in any one of the evaluators. The AR-ANS (p = 0.001), IF-AR (p = 0.006), AR-FPMA right (p = 0.001) and AR-FPMA left (p <0.001) and AR-FPME on both sides (p = 0.001) demonstrating significant differences between the two types of maxilla. Thus we verify that, as the tooth loss occurs, irreversible anatomical changes take place in the maxilla bone, which must be taken into account in the design and manufacture of prostheses and osseointegrated implants...

Este estudio propuso medir y comparar las medidas antropométricas entre los maxilares con y sin dientes. Fueron utilizados 26 cráneos humanos, 13 maxilares con dientes y 13 sin dientes. Las mediciones fueron realizadas a ambos lados por dos evaluadores entre las distancias del reborde alveolar (RA): a la espina nasal anterior (ENA), al canal incisivo (CI) y a lo foraámenes palatinos mayor (FPMA) y menor (FPME). Los datos mostraron que la media de las mediciones fueron proporcionalmente mayores en las maxilas con dientes, para todas las mediciones en cualquiera de los evaluadores. El RA-ENA (p = 0,001), AR-CI (p = 0,006), RA-APMA derecho (p = 0,001) y RA-APMA izquierdo (p <0,001) y RA-APME en ambos lados (p = 0,001), comprobando la existencia de diferencias significativas entre los dos tipos de maxila. Fue verificado que a partir de la pérdida dental ocurren irreversibles cambios anatómicos en el maxilar, que deben ser considerados en el diseño y fabricación de prótesis e implantes osteointegrados...
