A healing abutment, a healing abutment assembly and a selection method of the healing abutment are disclosed. The healing abutment includes a body and a positioning structure. The body includes an accommodating space, a healing surrounding surface, a top surface and a bottom surface. The bottom surface is connected to an implant. The healing surrounding surface is connected between the top surface and the bottom surface. The accommodating space is communicated with the top surface and the bottom surface. The top surface has a non-circular shape, and the healing surrounding surface is formed in a non-circular conical shape. The positioning structure is disposed on the top surface and removably connected to an auxiliary tool. The healing abutment assembly includes the healing abutment and a connecting member which is removably connected to the body and the implant. Therefore, the installation of the specific healing abutment on the different positions of the teeth can be successfully performed for gums healing, crowns insinstallation and fitting teeth shapes. In addition, the positioning structure cooperated with the auxiliary tool can prevent the healing abutment from rotating relative to the implant when the connecting member is rotated. Hence, the proposed structure of the present disclosure may improve the stability and safety of the installation of the healing abutment.本發明提供一種癒合帽、癒合帽組件及其選擇方法,癒合帽之本體包含容置空間、癒合環面、頂面及底面,其中底面對應抵接植體,且癒合環面連接頂面與底面之間。容置空間貫穿連通頂面與底面,頂面為非圓形,癒合環面非圓錐形。定位結構則設於頂面上,且定位結構係供輔助工具可拆卸地連接。癒合帽組件之固接件可拆卸地穿設於本體與植體。藉此,透過不同牙齒位置安裝特定的癒合帽,使牙肉的癒合及牙冠能順利安裝且符合齒形。特殊的定位結構配合對應的輔助工具,可防止固接件在螺鎖過程中造成癒合帽的位移轉動,進而提高安裝的穩定性。100‧‧‧癒合帽組件104‧‧‧植體1044‧‧‧端面200‧‧‧癒合帽300‧‧‧本體310‧‧‧容置空間320‧‧‧癒合環面330‧‧‧頂面332‧‧‧第一區域表面334‧‧‧第二區域表面340‧‧‧底面400‧‧‧定位結構410‧‧‧第三區域表面420a‧‧‧移動抵靠面500‧‧‧固接件510‧‧‧螺牙部520‧‧‧位移抵靠部522‧‧‧六角孔洞530‧‧‧連接部H‧‧‧高低差
