Dental implant is a technique of "planting" teeth. It uses biomaterials with good compatibility with human body to make artificial tooth root, "implants" it into alveolar bone, and then inserts realistic and hard porcelain crown on the tooth root, and a new tooth is "planted". Dental implants abandon the hooks and sleeves in traditional dental implants and do not use dental trays, not to mention wearing healthy teeth on both sides. There are the following types: American 3i dental implant system, Norbert dental implant system, Austrian wife dental implant system and Feyadan dental implant system. Jing Tian stomatologists tailor-made a unique dental implant program for you. After systematic and thorough general and local examination, the patient was confirmed as the indication of dental implant and decided to have implant surgery and restoration. At this time, the dentist of Jing Tian Hospital will make a unique implant restoration plan for you. (1) Selection of implant system: The selection of implant system should be combined with the conditions of patients and doctors. Whether the preferred implantation system is reliable, whether there are a large number of clinical practices observed for a long time, and whether there are really satisfactory results. (2) Bone mass and quality of the patient's jaw: According to X-ray examination, accurately understand the anatomical structure of the implant area. (3) The patient's economic conditions: For China, the main factor limiting the development of implant restoration at present is price. The price of implants abroad is high, which is difficult for the general public to accept. (4) Selection of implant site: From the point of view of restoration, when the free end is missing, the implant is most needed to provide support at the distal end of alveolar ridge; When the gap between missing teeth is too long, implants are used to provide abutment in the middle of the gap; In edentulous occlusion, complete denture and overdenture are supported and fixed by implants. (5) Determination of the number of implants: There are two factors: the first is the need for prosthesis support, and the second is the possibility of anatomical conditions. (6) Selection of implant superstructure: According to the specific situation of patients, the technical means mastered by doctors and the requirements of patients, various types of abutments and retention devices can be selected and matched with each other as appropriate. The reverse design principle can be used to complete the design accurately and obtain the best effect. The method is to arrange teeth on the model according to the requirements of aesthetics and occlusion, and determine the type of prosthesis, superstructure, implant position, implant quantity, implant direction and implant length. In this way, the final result of restoration is determined first, and then the restoration and implant are deduced and selected in reverse. The carrier of reverse design rules is surgical template, through which the initial design requirements can be controlled.
