초록
Edentulous patients with complete dentures commonly experience loss of masticatory force due to the wear of the prostheses. The presence of premature contacts and uneven bilateral balanced occlusion disturbs denture stability, resulting in difficulties with continuous denture use. The conventional qualitative occlusal analysis had its limitations, as it only subjectively compared the contact points and density. To compensate for the limitation, a quantitative method using digital occlusal analyzers can offer further information on the kinetic occlusion of the prosthesis. In these two clinical cases, digital occlusal analyzers were facilitated to analyze intercuspal relationships in the complete dentures and mandibular overdentures for quantitative analysis. This approach was practical for identifying the occlusal defects of the current dentures, evaluation of the mid-treatment process, and beneficial for establishing the bilateral balanced occlusion. However, the technical limitations of the digital occlusal analyzer should be acknowledged, such as potential film damage and reduced measurement accuracy with multiple uses.
