Implant - supported fixed prosthesis was designed to restore the edentulous area and improve esthetics 植體支持之固定補(bǔ)綴物將修復(fù)病患的大量缺牙與骨缺損以改善病患口腔功能與美觀。
Methods : the stress distribution in periodontal tissue was analyzed after thetilted abutment received fixed prosthesis using three - dimensional strain rosette 方法:應(yīng)用三維應(yīng)變花技術(shù)對(duì)不同傾斜角度基牙進(jìn)行固定修復(fù)后,對(duì)其牙周組織受力進(jìn)行分析。
Objective : to study the relationship between angle of tilted abutment and stress distribution of periodontal tissue , and todetermine the angle limit for fixed prosthesis 目的:探討基牙牙周組織受力與其傾斜角度的關(guān)系,找出能夠進(jìn)行固定修復(fù)的基牙傾斜角度的極限值。
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 結(jié)果:在一定范圍內(nèi)對(duì)傾斜基牙進(jìn)行固定修復(fù),使其牙周組織受力分布趨于均勻,有利于牙周組織的健康。
