Tempo de confecção clínica e laboratorial de placas oclusais convencionais x fresadas em pacientes com bruxismo do sono: ensaio clínico. 2022. 62f. Dissertação (Mestrado em Ciências Odontológicas) - Centro de Ciências da Saúde, Universidade Federal do Rio Grande do Norte, Natal, 2022.https://repositorio.ufrn.br/handle/123456789/49302The aim of the study was to compare the clinical and laboratory preparation time and clinical adjustments for the installation of conventional thermopolymerizable resin splint (CS) and milled CAD/CAM (MS) occlusal splints in patients with sleep bruxism. For this purpose, a controlled and non-randomized clinical trial was carried out in which patients diagnosed with probable sleep bruxism were included. CS (n = 24) and MS (n = 24) were prepared and the clinical preparation time (CPT), laboratory preparation time (LPT) and installation time (IT) were measured for each of the splints. The Mannwhitney test with a confidence level of 95% was used in the SPSS IBM Statistics program to analyze whether there is a difference between the analyzed times and the type splint performed. As a result, it was found that CS had higher total CPT (mean of 94,39 min) in relation to MS (17,85 min) (p0<001). However, the total LPT of the CS was lower (164,80 min) than the MS (182,64min) (p=0.015). For the IT, it was found that the MS had an average of 21,26 min, while the CS had 37,19min (p0<001). In conclusion, within the limitations of the study, it was observed that the milled splint had a shorter clinical time both in the manufacturing and installation stages. However, the laboratory preparation time of the conventional splint was shorter.Acesso AbertoDesenho auxiliado por computadorDesgaste dos dentesOclusão dentáriamasterThesisCNPQ::CIENCIAS DA SAUDE::ODONTOLOGIA
