Reliability of Measuring the Occlusal Contact Area


Now online in the Journal of Prosthodontics, Drs. Raul Ayuso-Montero, Yumaysla Mariano-Hernandez, Laura Khoury-Ribas, Bernat Rovira-Lastra, Eva Willaert, and Jordi Martinez-Gomis evaluate the reliability of T‐scan and 3D intraoral scan techniques for assessing the occlusal contact area (OCA), compared to occlusal registration and also assess the validity of the techniques.

The authors concluded that T‐scan is a reliable method for measuring the OCA, but the 3D surface scan is not. In addition, occlusal registration showed a high validity.
