SUMMARY:

The study evaluated the conventional occlusal splint (PC) and the one made by milled CAD / CAM (PF) in patients with sleep bruxism regarding their surface roughness and their sleep quality. Materials and Methods: A pilot study was composed of two groups: PC; N = 5 and PF; N = 13. The selected patients were evaluated for the presence of bruxism and completed the Pittsburgh Sleep Quality Index (PSQUI-BR). Occlusal splints were made, occlusal adjustments were did and surface roughness was evaluated after 15 and 60 days of installation. For the analysis of roughness, the most posterior contact point on the splint and the canine guide region were considered bilaterally, so the splint had four points of analysis, two anterior and two posteriors. Analysis was performed using CCI MP non-contact 3D optical profileometer; the data were obtained and analyzed using the Taysurf CCI software (Taylor Hobson). Results: the values (15 days) of Sa and Ra for CP were 34.17 and 32.82 respectively, while the PF values showed less roughness, with Sa = 29.72 and Ra = 26.13. After the 60-day evaluation, the PF group continued to have less roughness than the PC group, which indicates lower surface roughness, that is, greater surface smoothness. As for the quality of sleep, there were no variations when observed at 15 and 60 days. Conclusion: The PF group showed lowest surface roughness when compared to the PC group, for the Sa and Ra analyzes at both times evaluated; as for the quality of sleep, there was no variation between the groups analyzed in the two periods.
