Abstract(s)
A adaptação marginal é uma das principais chaves para o sucesso clínico a longo prazo das reabilitações orais. Paralelamente existem outros fatores que influenciam o ajuste de uma reabilitação oral fixa, nomeadamente o material de restauração, o tipo de restauração, a linha de terminação, entre outros. Existem ainda diversos fatores humanos que condicionam o resultado, tais como a experiência do profissional e o conhecimento teórico do mesmo.
Uma coroa mal ajustada acarreta problemas no futuro, sendo potencialmente prejudicial para o suporte periodontal, podendo levar à acumulação de placa bacteriana e microinfiltrações que posteriormente, traduzem-se em cáries secundárias, irritação gengival e trauma associado à reabilitação. Além de que uma má adaptação marginal pode originar a dissolução do cimento, o que contribui igualmente para que no futuro surjam complicações como cáries secundárias, recessão gengival e doença periodontal.
Com o constante desenvolvimento tecnológico e o avanço na medicina dentária digital, atualmente é possível evitar múltiplos erros decorrentes do material de impressão e ainda da experiência do médico. A principal evolução foi a introdução na prática clínica de sistemas CAD-CAM que facilitam bastante a realização das reabilitações orais fixas com maior precisão, reproduzindo cada detalhe minuciosamente.
Esta revisão narrativa tem como objetivo analisar e comparar as técnicas atuais de impressão digital com as técnicas convencionais para confeção de estruturas em cerâmica e sua adaptação marginal.
Marginal adaptation is one of the keys to the long-term clinical success of oral rehabilitation. At the same time, there are other factors that influence the adjustment of a fixed oral rehabilitation, namely the restoration material, the type of restoration, the finishing line, among others. There are also several human factors that condition the result, such as the professional's experience and theoretical knowledge. An ill-fitting crown causes problems in the future, being potentially harmful to the periodontal support, because it can lead to the accumulation of bacterial plaque and microleakage, which later translate into secondary caries, gingival irritation and trauma associated with rehabilitation. In addition, poor marginal adaptation can lead to cement dissolution, which also contributes to complications such as secondary caries, gingival recession and periodontal disease in the future. With the constant technological development and advances in digital dentistry, it is currently possible to avoid multiple errors coming from the impression material and also from the physician's experience. The main evolution was the introduction into clinical practice of CAD-CAM systems that greatly facilitate the performance of fixed oral rehabilitation with greater precision, reproducing every detail. This narrative review has the main purpose to analyze and compare current digital printing techniques with conventional techniques for making ceramic structures and their marginal adaptation.
