Tempo de confecção clínica e laboratorial de placas oclusais convencionais x fresadas em pacientes com bruxismo do sono: ensaio clínico

Abstract

The 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.
