Abstract：Objective To investigate the clinical effect of zirconia endocrown in repairing of low occlusal gingival distance molar. Methods From January 2017 to March 2018, 38 patients (40 affected teeth) admitted to the Department of Stomatology, Shunyi Hospital, Beijing Hospital Traditional Chinese Medicine were selected. All patients were treated with zirconia endocrown. At two weeks, six months, and twelve months after restoration, the edge closeness, restoration integrity, adjacency, abutment loosening or fracture, secondary caries, and gingival condition were assessed. Results After two weeks of reexamination, all the evaluation indexes of 40 low occlusal gingival distance molars after restoration reached the clinically acceptable level. After six months of reexamination, the gingival hyperemia of two affected teeth was mild, no bleeding was found by probe, and no problems of the prosthesis or abutment teeth were found in the rest. At twelve months of reexamination, one affected tooth had poor adjacency relationship; one affected tooth had mild gingival hyperemia and no bleeding was observed by probe; one affected tooth had gingival hyperemia and bleeding was observed by probe, and the rest had no problems with the prosthesis and abutment teeth. Conclusion Zirconia endocrown has a good clinical effect in repairing the defect of molar with low occlusal gingival distance, and it is safe, reliable, beautiful and practical.
