在骨整合成功與牙科植體有效輔助下，針對局部與全部缺牙患者的治療方式已有重大的改變，特別是因齒槽骨嚴重吸收所帶來復體穩定、固位與使用舒適性所面臨到的困境。牙科植體輔助活動式局部義齒提供患者穩定且長期預後佳的復治療方式，牙科植體輔助覆蓋式義齒相較於傳統全口義齒具有更佳的咬合力量與咀嚼效能；以兩支牙科植體作輔助的覆蓋式義齒已成為處理下顎全部缺牙的標準復選項，且有效解決傳統復體使用時所遭遇到的不舒適性。

The introduction of osseointegration and implant-assisted prostheses has led to a shift in the therapeutic paradigm for the management of partially and fully edentulism ,where the problem of advanced alveolar
resorption and the associated difficulty in providing stable, retentive, functionally comfortable prostheses creates the biggest challenges. Implant-assisted removable partialdentures provide patients with stable,
long-term predictable prostheses and could serve as a long-term predictable treatment modality. Implantassisted overdenture treatment permits better biting and chewing function than conventional complete
dentures. 2-implant-assisted overdenture in the mandible should be the standard treatment option for fully edentulous patients suffering from discomfort with their conventional denture.
