Abstract:

Occlusal design is one of the most important factors affecting the osseointegration and long-term stability of implant restorations. A well-designed occlusion helps evenly distribute occlusal forces to the implant and its surrounding bone tissue, thereby promoting the health of peri-implant soft and hard tissues. By contrast, occlusal overload and nona-xial forces caused by improper occlusal design are key factors contributing to dental implant failure in the long term. Therefore, occlusal design directly affects the success rate and long-term outcomes of implant restorations. This work reviews the relationship between the neuromuscular system and occlusal design, factors influencing occlusal contact design, and occlusal changes after implant-supported single-crown restorations. The findings provide guidelines for occlusal design in implant-supported single crowns in posterior regions.

Key words: mandibular posterior tooth area, implant single crown, occlusal design
