Accuracy of Dental Contacts of an Occlusal Splint Made According to Conventional or Digital Techniques Using GeoMagic®.

"Comparative Study of the Accuracy of Dental Contacts of an Occlusal Splint Made According to Conventional or Digital Techniques Using GeoMagic®."

To compare the accuracy of the occlusal splints made by conventional impression and milled with the splint made by intraoral scanner and milled.

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).

Inclusion Criteria:

• Patients between 18 to 70 years old.
• Patients who maintain until first molar in both arches.
• Patients who need occlusal splints due to bruxism.

Exclusion Criteria:
