Abstract

Abstract: Objective: To prospective study the clinical efficacy of three restoration methods for short crown molars. Methods: After root canal treatment, 68 short crown molars were repaired with lithium disilicate reinforced glass ceramic onlays (group A, n=36), fiber split post zirconia onlays (group B, n=17), and cast pure titanium split post metal onlays (group C, n=15). The clinical evaluation was performed 3 years later. Results: In group A, group B, and group C, the success rate of restoration was 88.9%, 94.1%, and 80.0%, and the survival rate of prostheses was 88.9%, 100.0%, and 93.3%, respectively, and the survival rate of abutments was 100.0%, 100.0%, and 93.3%, respectively, with no statistical significance (P>0.05). Conclusion: The three methods can achieve good clinical effect after root canal treatment of short crown molars, which can meet the repair needs of patients with short crown molars of different levels.

Key words: short crown molar, lithium disilicate reinforced glass ceramic onlay, fiber split post zirconia onlay, cast pure titanium pile post metal onlay, clinical study
