Abstract(s)
A reabilitação oral com recurso a prótese fixa é uma solução cada vez mais utilizada pelos médicos dentistas. Deste facto advém a necessidade de preparar o dente para receber a restauração. Desde a decisão do tipo de preparação dentária a usar e localização da linha de terminação, existe um estudo das condições e possibilidades do caso. É então fundamental perceber quais são as situações nas quais se aplica cada tipo preparação, baseado na evidência científica, por forma a obter o sucesso clínico. Deste modo, torna-se indispensável o conhecimento sobre a influência de cada um destes tipos, nomeadamente nos parâmetros periodontais – índice de placa, índice gengival, profundidade de sondagem e hemorragia à sondagem – e a consequente resposta histológica tecidular.
Oral rehabilitation by fixed prothesis is becoming a more often used solution by dentists. From this, comes the need to prepare the tooth to receive the restauration. Before the decision on the type of preparation to be used and location of the finishing line, there must be a study of the condition and case possibilities. For this, it's essential to understand what are the situations that each type of preparation is suited for, based on scientific evidence, in order to reach clinical success. Therefore, it's indispensable to have the knowledge on the influence of each one of these types, specifically on the periodontal parameters – plaque index, gingival index, probe depth and bleeding on probe – and its consequent tissue histological response.
