Introdução: O conceito de estética é subjetivo, logo a literatura indica que fazer uma restauração estética com qualidade é quase tão importante para a saúde mental de um indivíduo como para a saúde dentária. Desta forma, quando ocorre a perda dentária, o restabelecimento da função e estética devem ser cumpridos. Para que a reabilitação oral ocorra, o estado de saúde oral do paciente no que respeita a higiene, ausência de patologias, mucosa, dentes e osso alveolar devem ser avaliados. Existem vários tipos de reabilitações protéticas nomeadamente as próteses removíveis e fixas que podem ser implanto-suportadas, dento-suportadas ou muco-suportadas. A preparação da linha de terminação para prótese fixa é crucial. Geralmente existem dois tipos de preparações: preparações com linhas de acabamento designadas por horizontais; e preparações sem linhas de acabamento designadas por verticais.
Objetivo: Explorar a importância da correta adaptação marginal da coroa protética ao dente e a sua relação com a reabilitação oral. Enumerar as consequências clínicas de uma inadequada determinação linha de acabamento no dente e adaptação da coroa protética.
Metodologia: Revisão narrativa da bibliografia selecionada de acordo com as palavras-chave e objetivo do trabalho
Discussão e Conclusão: A reabilitação dentária de sucesso está assente em três premissas: a saúde oral, a durabilidade da prótese e as expectativas do paciente. O médico dentista deve ter um conhecimento profundo dos procedimentos a executar e efectuar o planeamento prévio da reabilitação dentária. Com este trabalho foi possível inferir que não existe uma linha de término de eleição devido às diferentes situações clínicas existentes e que, independentemente do tipo de reabilitação dentária, deve ser o mais conservadora possível, sendo a localização supra-gengival preconizada se não houver comprometimento estético. A homeostasia dos tecidos deve ser assegurada, preservando a saúde periodontal dos tecidos envolvidos. Assim, uma boa adaptação marginal é fundamental para a longevidade do tratamento.
Introduction: The concept of aesthetics is subjective, so the literature indicates that making a quality aesthetic restoration is almost as important to an individual's mental health as it is to dental health. Thus, when tooth loss occurs, restoration of function and aesthetics must be satisfied. For oral rehabilitation to occur, the patient's oral health status regarding hygiene, absence of pathology, mucosa, teeth and alveolar bone should be assessed. There are several types of prosthetic rehabilitations namely removable and fixed prostheses that can be implant-supported, tooth-supported or mucus-supported. The preparation of the fixed prosthesis termination line is crucial. There are usually two types of preparations: preparations with finishing lines called horizontal; and preparations without finishing lines called verticals. Objective: To explore the importance of the correct marginal adaptation of the prosthetic crown to the tooth and its relationship with oral rehabilitation. List the clinical consequences of inadequate tooth finish line determination and adaptation of the prosthetic crown. Methodology: Narrative review of the bibliography selected according to the keywords and the objective of the work. Discussion and Conclusion: Successful dental rehabilitation is based on three premises: oral health, durability of the prosthesis and patient expectations. The dentist must have a thorough knowledge of the procedures to perform and carry out the advance planning of dental rehabilitation. With this work it was possible to infer that there is no end line of election due to the different clinical situations and that, regardless of the type of dental rehabilitation, should be as conservative as possible, and supra-gingival location is recommended if there is no aesthetic compromise. Tissue homeostasis should be ensured, preserving the periodontal health of the tissues involved. Thus, good marginal adaptation is critical to the longevity of treatment.
