Description

Substitute for dental implant Technical Field The utility model belongs to the technical field of dentistry, and particularly relates to a substitute for dental implantation. Background In the dental intraoral dental implant technology, a traditional substitute is mainly used in a plaster model, and has the main function of transferring implant information in the oral cavity of a patient to the plaster model, so that a dentist technician can conveniently design a superstructure such as a base on the substitute. With advances in technology, acquisition of three-dimensional images of a patient's mouth by an intraoral scanner has emerged, with the patient's mouth model being printed directly using a 3D printer. The traditional substitute is made of metal materials generally, and the metal substitute is worn out in the use process to cause inaccurate positioning, particularly when a 3D printing technology is used, the substitute is not accurate in reduction of the condition in the oral cavity of a patient after the abutment is installed, and even the condition that the denture manufactured by a dentist technician is not matched with the oral cavity of the patient possibly occurs. Disclosure of utility model In order to solve the problems, the utility model provides a dental implant substitute. The dental implant substitute is made of resin, preferably polymethyl methacrylate (PMMA) with low cost, convenient processing, high strength and easy polishing, and can be directly replaced by a dentist technician after being used for a period of time due to low manufacturing cost, low replacement cost and easy recovery. The utility model provides a tooth replacement body, including the butt joint portion, location section and fixed section, the butt joint portion set up inside the fixed section, the butt joint portion link to each other with the base station, the location section link to each other with the dental cast body, when planting the tooth, can set up the planting body in patient's oral cavity, in order to transfer the planting information in patient's oral cavity to the gypsum model on, insert the scanning rod on planting body, be formed with the joint groove in the planting body, the one end and the joint cooperation of joint groove of scanning rod, then scan the position that the tooth needs to be planted with intraoral scanner, record scanning rod inserts position and inclination that need to plant the tooth, according to the information that intraoral scanner scanned out, use 3D printer to print out the dental cast body, have the guiding position hole that needs to plant the tooth on the dental cast body, this guiding position hole is the position of replacement body, the location section insert in the guiding hole can design and correspond with the shape of replacement body location section. The utility model provides a tooth die body, including tooth die body, location section, connecting portion and fixed section, butt joint portion center department is provided with the butt joint groove, the butt joint groove include changeover portion and cross section be the draw-in groove of regular polygon, preferably, the cross section of draw-in groove is regular hexagon, with the limit number adaptation of general oral cavity implant, the surface of location section is provided with convex arch, bellied number is the same with the limit number of draw-in groove, and every limit and every protruding both positions one-to-one of draw-in groove, when installing the replacement body on the tooth die body (in the guide way was inserted to the location section), fully fix a position with the tooth die body through a plurality of archs on the replacement body, simultaneously, because every arch and every limit both positions one-to-one correspondence of draw-in groove, so according to the position of every arch, can confirm the position of draw-in groove, it is more abundant to patient oral cavity condition reduction after the mount base. The bottom of the clamping groove is provided with a countersunk hole, the upper part of the countersunk hole is provided with an internal thread, the internal thread is matched with an external thread of a screw for fixing the abutment, the abutment is fixed on a substitute, a technician can conveniently design and manufacture the denture, a channel which can screw out is reserved in the middle of the denture, and the channel can be closed after the prosthetic denture is installed in the oral cavity of a patient.
