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: at time 0 (t0 = 15 days) the PC group showed higher roughness in the two analyzes (Sa = 34.71 and Ra = 32.82) than the PF group (Sa = 29.72 and Ra = 26, 13). After evaluation at time 1 (t1 = 60 days), the mean roughness of the CP group was lower (CP, Sa = 28.8; Ra = 25.69), while the PF group presented (Sa = 32.4; Ra = 29.1).. Conclusion: The PC group showed higher surface roughness when compared to the PF group, for the Sa and Ra analyzes at t0, but when observed at t1, the roughness of the PC group was lower.
