Abstract:
Objective :To research the feasibility and preliminary clinical effect of an implant-supported fixed bridge based on interactions with the posterior interocclusal space deficiency.
Methods:Four patients with multiple implant-supported fixed-bridge restorations for interocclusal space deficiency in posterior teeth were included in this study. The 8 total implant sites had an average interocclusal space size of 3.3 mm. Two abutments with an undercut area were performed, the fixed bridge was placed by rotating it without a common path of insertion, and the abutment screw was then tightened. In the production process, the interaction retention concept and methods were fully communicated to the technician. The abutments and bridges on the implants were placed, and the clinical effect was observed.
Results:The prosthesis was fixed well and presented appropriate functioning. At the 3-month and 18-month follow-up examination, the prosthesis and abutments were not loose, and the abutments did not release or break. No swelling or tenderness was observed in the margin of the implants.
Conclusion :The interaction retention is a good method of resolving the problem of interocclusal space deficiencies in the posterior teeth. - Full text:交互固位在后牙多植体支持固定桥修复的临床应用.pdf
