The utility model has the plant tooth body of high combination stability,It includes there is a body of rod,And one helical ring set the threaded portion on the what body of rod； Wherein,The body of rod includes the first section of a second end extension from the first end of the body of rod toward the body of rod,One connects first section and the second section toward the second end extension,And the bar diameter of aforementioned first section Yu the small what of bar diameter of junction of second section second section； ThereforeIt is designed through the bar diameter of the junction of the big what of bar diameter of the second section first section and the second section,When so that the plant tooth body being implanted into alveolar bone,What it can increase that dentist, odontologist locks locks sense,It effectively increases and plants outside tooth initial stage stability,And what plant tooth body Hou is coated as the tooth socket bone uptake Hou,Second section will by the close clip of the alveolar bone,The facts for effectively avoiding reactive torque produced in mastication processes and the plant tooth body being caused to loosen,Promote the plant tooth physical efficiency stablize the clip what alveolar bone on,Effectively improve the reliability combined.本新型具高結合穩定性之植牙體，其包含有一桿體，以及一螺旋環設於該桿體上之螺紋部；其中，該桿體包括有一由該桿體之第一端往該桿體之第二端延伸之第一區段，一連接該第一區段並往該第二端延伸之第二區段，而前述該第一區段與該第二區段之連接處的桿徑小於該第二區段的桿徑；是以，透過第二區段之桿徑大於該第一區段與第二區段之連接處之桿徑設計，使得該植牙體植入齒槽骨時，其可增加牙醫師鎖入之鎖附感，有效增加植牙初期穩定度外，並當該齒槽骨生長後而包覆於該植牙體後，該第二區段將受到該齒槽骨之緊密卡掣，有效避免咀嚼過程中所產生之反向扭矩而造成該植牙體鬆脫之情事，促使得該植牙體能穩定卡掣於該齒槽骨上，有效提高結合之可靠度。
