目的:探讨基牙牙周组织受力与其倾斜角度的关系,找出能够进行固定修复的基牙倾斜角度的极限值。方法:应用三维应变花技术对不同倾斜角度基牙进行固定修复后,对其牙周组织受力进行分析。结果:在一定范围内对倾斜基牙进行固定修复,使其牙周组织受力分布趋于均匀,有利于牙周组织的健康。结论:基牙倾斜角度在70度内可以进行固定修复。
目的:探討基牙牙週組織受力與其傾斜角度的關繫,找齣能夠進行固定脩複的基牙傾斜角度的極限值。方法:應用三維應變花技術對不同傾斜角度基牙進行固定脩複後,對其牙週組織受力進行分析。結果:在一定範圍內對傾斜基牙進行固定脩複,使其牙週組織受力分佈趨于均勻,有利于牙週組織的健康。結論:基牙傾斜角度在70度內可以進行固定脩複。

Objective:To study the relationship between angle of tilted abutment and stress distribution of periodontal tissue, and todetermine the angle limit for fixed prosthesis. Methods:The stress distribution in periodontal tissue was analyzed after thetilted abutment received fixed prosthesis using three-dimensional strain rosette. Results:The stress distribution in periodontaltissue kept balanced for the cause of fixed prosthesis of tilted abutment in a proper range, which will be good for periodontaltissue health. Conclusion: Abutment tilted less than 70 degrees can be fixed and repaired.
