Abstract

Obtaining precise occlusal registration is one of the main issues in prosthodontics. The adequate trimming strategy of bite material and removing the bubbles in the cast are important and time-consuming procedures to acquire the correct occlusal registration in the conventional pathway. In the era of digital dentistry, the use of intraoral scanners has been widely spread out, and the occlusal registration step is automatically performed through the software algorithm. However, the accuracy of occlusal registration using intraoral scanners is differ-ent depending on the digital trimming strategy. Clinicians are required to understand the theoretical knowledge for occlusal registration and data trimming strategy.
