Abstract:
Multiple stages of digital fixed restorations may have impact on the occlusal accuracy of the final restorations.Among them, the determination of occlusal plane, the records of static and dynamic occlusion are key stages.Facing the situation of more residual roots, residual crowns, as well as unstable occlusion in elderly people, the accurate occlusal records are of greater significance.This review focuses on above influencing factors combined with evaluation methods for occlusal accuracy.It is believed that in general, whether to transfer personalized occlusion plane should be decided according to the clinical needs, meanwhile fixed restorations made by directly scanning static occlusion under heavy bite force, and obtaining dynamic occlusion using mandibular movement system have more accurate occlusal morphology.However, more randomized controlled clinical trials with large sample size supporting this field of research are still needed for the elderly population.
