An adjustable dental implant comprises an implant body, a connecting structure, and two wings. The implant body comprises a fixture and an abutment. The fixture comprises a top, a bottom, a peripheral surface connected between the top and the bottom, and a joining portion formed on the peripheral surface. The abutment is set on the top of the fixture. The connecting structure is set between the fixture and the abutment. The wings are pivotally connected with two opposite sides of the connecting structure. Or, one of the wings is pivotally connected with the connecting structure, and the other wing is fixed with the connecting structure. The wing or the wings may be adjusted to fit the surface of the cortical bone. Dental posts are allowed to penetrate the alveolar bone entirely to secure the fixture.一種牙植體,其包含一植體根部、一支台部以及一固定覆體,該支台部形成於該植體根部頂端,該固定覆體設於該植體根部與支台部之間,該植體根部係能植入於人體口腔的齒槽骨中,使植體根部外周面的齒槽骨結合體與齒槽骨產生骨整合,該支台部伸出牙齦皮瓣外,用以固接一人工牙冠,該固定覆體則以其相對於植體根部兩側的第一翼片部與第二翼片部覆設於齒槽骨表面,且該固定覆體結合骨釘或螺絲等固接元件固定於齒槽骨上,藉此,提供一能牢固、不鬆動、易操作且低成本的牙植體。1牙植體 10植體根部 13槽形結合部 131環形凹槽 14止轉結合部 141止轉凸條 20支台部 21支台基段 22支柱段 221組接凹槽 30固定覆體 31第一翼片部 312穿孔 32第二翼片部 322穿孔
