Abstract: Occlusal reconstruction involves multiple disciplines and covers a wide range of knowledge. It demands not only comprehensive and systematic examination and analysis，careful treatment plan and various treatment steps，but also attention to the details of repair and accurate implementation. It is a complicated sequential treatment process with high difficulty，so it often requires doctors to have rich clinical experience. Based on the classical theory and clinical experience of occlusal reconstruction as well as the suggestions from experts of other specialties，the authors divide the complicated occlusal reconstruction process into six phases，including examination and design stage，oral preparation stage，jaw position adjustment stage，provisional restoration stage，permanent restoration stage and follow-up and maintenance stage，and treatment steps and precautions at each stage are described in detail. This article also presents a clinical case completed under the guidance of this principle，in order to comb through the complicated treatment process of occlusal reconstruction and elaborate the treatment details of different stages，so as to provide a set of practical treatment principles for clinical reference.
