简要总结
To compare the accuracy of the occlusal splints made by conventional impression and milled with the splint made by intraoral scanner and milled.
详细描述
Forty participants received two different occlusal devices from two different workflows (fully conventional and fully digital). Every splint was scanned before and after the occlusal adjustments in order to compare the volumetric changes. Furthermore, the scans were compared in a software Geomagic® Control X calculates and measures the distance from every surface point from the initial dataset (occlusal devices before adjustment) to the final dataset (occlusal device after adjustment).

Volumetric changes assessed in Root Mean Square (RMS)
时间窗: 1 week
The software of automatically graphical comparisons called Geomagic® Control X (Geomagic Inc., 3D Systems Inc., USA) will be used to calculate the accuracy by measuring the distance (positive or negative) from every surface point from the initial dataset (occlusal devices before adjustment) to the final dataset (occlusal device after adjustment). This approach will give us the mean of the simple arithmetic difference.
