Objective To discuss the fixed restoration for severe dental attrition with partial dentition defect. Methods We selected 15 patients who had received treatments in Hebei Ophthalmology Hospital due to dental allergy, chewing weakness and temporomandibular joint dysfuction caused by severe attrition from February 2007 to October 2012. Among them, there were 9 males and 6 females, aged from 22 to 58 years old averaging 33. We performed occlusal reconstruction by fixed restoration for these patients, recovered their vertical dimension, and then carried out the follow-up. Results In the two-year follow-up, two patients had porcelain cracking, one patient's metal-ceramic crown dropped; no gingiva swelling occurred, periodontal tissues were healthy, occlusal functions recovered well, temporomandibular joint dysfunction and masticatory muscles were not discomfortable, subfacial 1/3 was normal, and patients were satisfied with their appearance and facial contour. Conclusion Using the fixed restoration to reconstruct occlusions can effectively recover patients' masticatory functions, add height for subfacial 1/3, and improve the symptoms of temporomandibular joint.
