This study intends to adopt a multicenter, randomized controlled, single-blind, non-inferiority clinical trial design. 246 premolars that meet the inclusion criteria after complete root canal treatment will be selected from the clinical practice and randomly divided into two groups. One group will be restored with the modified endocrown, and the other group will be restored with personalized post and core combined with full crown. Follow-up visits were conducted at 6 months, 1 year and 2 years after the operation respectively. Through clinical and imaging examinations, the survival rates of the two different restorations were evaluated and used as the main evaluation indicators to fill the gap in efficacy data of the modified endocrown in clinical applications, providing a strong evidence-based medical basis for subsequent restoration improvement and standardized application.
1: The affected tooth was a premolar that had undergone complete root canal treatment for two weeks. Both imaging and clinical examinations indicated no abnormal periapical reactions.
