Including: clinical examination and imaging examination, diagnosis and treatment design, surgery, dental production and repair, and maintenance of implants and repair bodies. According to the time relationship between implant implantation and tooth extraction, planting surgery can be divided into instant planting, delay and instant (within 3 months after tooth extraction), and delayed planting (3 months and longer after extraction). According to the time relationship between the weight of the body and the implant implantation, planting repair can be divided into instant negative weight, early load, and delayed load. With the development of oral phytology, the cycle of treatment is significantly shortened, and the implantation of implant is immediately put on dental implants, and even tooth extraction is possible.
