Abstract: Objective: To introduce the fabrication process of technician part in occlusal reconstruction through a case of occlusal reconstruction. Methods: A patient with severe mandibular tooth wear accompanied by porcelain of anterior prosthesis was selected. A stable occlusal plate was used to restore the vertical distance, the function and shape of the tooth was diagnostic wax-up, the temporary crown was directly transformed by pressing occlusal pad, and the temporary crown shape was reproduced by computer aided design/computer aided manufacturing(CAD/CAM) to make permanent prosthesis. Results: After the final repair, the patient's pronunciation and condylar track recorder were checked and satisfactory results were achieved. After treatment, follow up examination at 1, 3, 6 and 12 months later showed that the patient had no abnormal facial shape, clear articulation, no abnormal joint muscles, uniform distribution of bite force and smooth extension and lateral movement without interference by T-scan. Conclusions: The patient’s appearance and function were restored by the sequence therapy of occlusal reconstruction, and good results were obtained.
