This creation is a stepless dual-use implant that includes a body: the upper end of the body is provided with a recessed inner hole for assembly, the lower part of the body is a self-tapping lock-in forming end, the outer part of the lower part is a threaded part, and the appearance of the threaded part Rough surface treatment. Self-tapping symmetrical three grooves are set under the threaded portion, which is convenient for self-tapping to lock the alveolar bone to the precise depth. The outer surface of the upper part of the body has two different rough surface treatments, the upper and lower sections. The surface roughness is 0.5 to 1.0 μm, and the surface roughness of the outer surface of the lower segment is 1.2 to 4.0 μm. The hole roughness of different surface treatments of the upper and lower segments can simultaneously meet the proliferation of different tissue cells in the gum and alveolar bone. It can be suitable for the implantation requirements of gingival type implants or bone level implants, and can meet the osseointegration and gum fit, improve the closeness of the implant to the jawbone, and increase the fixation of the implant. force.本創作係一種無段式雙用植體，包含一本體：該本體上部上端設有內凹的組接內孔，該本體下部為自攻鎖入形成端，下部外側為螺紋部，螺紋部外表做粗糙表面處理，螺紋部的下方設有自攻對稱三溝槽，便於自攻鎖入齒槽骨到精確深度；本體上部外表面有上、下兩段不同的粗糙表面處理，上段的外表面的表面粗糙度為0.5至1.0μm、下段的外表面的表面粗糙度為1.2至4.0μm，運用上下段不同表面處理的孔洞粗糙度，能同時滿足牙齦與齒槽骨不同的組織細胞的增生需求，可同時適用於牙齦型(Tissue level)植體或牙骨型(Bone level)植體的植牙需求，並滿足骨整合與牙齦貼合、提升植體與顎骨的密合度、增加植體的固定力。
