Digital Occlusal Contact Area Indicates Masticatory Performance for Normal Occlusion, but Not for Malocclusion.

ABSTRACT:

Objectives

Since 1949, occlusal contact area (OCA) has been recognised as an indicator of masticatory performance (MP), but it required individual and laborious analog measurement. Today, a digital workflow could provide automatic quantification.

Objective

To find optimal parameters for a digital evaluation in terms of maximising correlation between OCA and MP.

Methods

MP was measured clinically by comminution of standardised test food by 41 participants (mean age = 29, n female = 28), including 18 patients with dentofacial deformities and 23 healthy subjects with normal occlusion. OCA was measured in the laboratory. After impression taking, gypsum casts were digitised (D2000, 3shape) and aligned in maximum intercuspidation (Geomagic Design X2022, 3D Systems). The max
