Detailed Description
The utility model discloses a plant planting base station intraoral locator for be located the base station on the planting body in patient's oral cavity, make the base station place in exact mounted position, thereby supplementary prosthesis accuracy is taken one's place.
Referring to fig. 5 and 6, the intraoral positioner of the implant abutment comprises a working model 5, an implant substitute 6, an abutment 2, a fixing bolt 3, a positioning main body 7 and at least one supporting wing 8.
The working model 5 is made by copying plaster by taking the oral cavity of a patient as a prototype, and has the same oral cavity structure with the patient, including teeth, gingiva, alveolar bone and the like.
The implant substitute 6 is completely the same as an implant implanted in the oral cavity of a patient in structure and size, is installed in an alveolar bone where a tooth position is lost in the working model 5, is also installed in the working model 5 at the same position as the implant in the oral cavity of the patient, and is internally provided with a threaded hole matched with the fixing bolt 3.
The abutment 2 is an integral structure formed by connecting a crown connecting section 21, a gingival sulcus penetrating gingival section 22 and a body connecting section 23 from top to bottom, is arranged on the implant substitute body, and is internally provided with a step hole 24 penetrating through the gingival sulcus penetrating gingival section 22 and the body connecting section 23.
The fixing bolt 3 is inserted into the threaded hole of the implant substitute 6 through the stepped hole 24 of the base 2 and is in threaded connection with the threaded hole, so that the base 2 is mounted in place on the implant substitute 6.
As shown in fig. 5-7, the positioning body 7 is a cylindrical structure, which is sleeved outside the abutment 2, and the inner wall surface 70 of the positioning body is matched with and closely attached to the surface shape of the crown connecting section 21 of the abutment 2. In order to prevent the positioning body 7 from contacting the gum in the oral cavity of the patient and prevent the gum having elasticity from acting on the positioning body 7 to shift its position, the height of the positioning body 7 is less than or equal to the height of the crown connecting section 21 of the abutment 2 and does not extend to the gingival sulcus-penetrating section 22 of the abutment 2.
The positioning body 7 is made of resin, can be manufactured by a technique such as an inverse mold process or 3D printing, and is preferably molded by an aqueous resin on the surface of the crown connecting section 21 of the abutment 2, and has a low manufacturing cost and a simple process.
In order to improve the stability of the positioning main body 7 and the accuracy of positioning the abutment 2, the positioner in the implant abutment mouth of the embodiment comprises two supporting side wings 8, and the two supporting side wings 8 are respectively arranged at two sides of the positioning main body 7.

The bottom surface 80 of the supporting side wing 8 is matched with the shape of the adjacent dentognathic face of the missing tooth position in the working model 5 and is tightly attached.
The support wings 8 are made of resin, and may be formed by a reverse molding process or 3D printing, and are preferably molded from an aqueous resin on the adjacent maxillofacial surface where the tooth site is missing in the working model 5.
When the adjacent tooth of the missing tooth position is far away from the adjacent tooth (the number of missing teeth in the oral cavity of the patient is large, and the tooth position is in a continuous missing state), the length of the supporting side wing 8 needs to be longer. In order to improve the overall strength of the supporting side wings 8, reinforcing ribs are arranged in the supporting side wings 8, so that the reinforcing effect is achieved, and the supporting side wings 8 are prevented from deforming or breaking to influence the positioning effect. Preferably, the reinforcing ribs are metal wires or wood rods, are made of easily available materials, can be embedded in resin, and can meet the reinforcing requirement.
The abutment 2 and the positioning main body 7 sleeved outside the abutment 2 are moved together to the implant of the missing tooth position in the oral cavity of the patient, and the position of the positioning main body 7 is adjusted, so that when the bottom surface 80 of the supporting side wing 8 is matched with the adjacent dentofacial surface of the missing tooth position in the oral cavity of the patient, the abutment 2 is positioned.
The manufacturing and using method of the planting base intraoral positioner is as follows:
1) using the oral cavity of the patient as a prototype, and filling a working model 5 with gypsum;
2) implanting an implant substitute 6 into an alveolar bone where a tooth position is missing in the working model 5 to simulate the state of the implant in the oral cavity of a patient;
3) placing the base platform 2 on a correct installation position on the implant substitute 6, then passing the fixing bolt 3 through the stepped hole 24 of the base platform 2, inserting into the threaded hole of the implant substitute 6, and then screwing the fixing bolt 3 to realize threaded connection with the threaded hole, thereby completing the installation of the base platform 2 on the implant substitute 6;
4) dipping water-based resin with a writing brush to coat the surface of the crown connecting section 21 of the base station 2, and volatilizing moisture to obtain a formed positioning main body 7 sleeved outside the base station 2;
5) coating the adjacent dentofacial surfaces missing tooth positions in the working model 5 with water-based resin dipped by a writing brush, curing the resin on the adjacent dentofacial surfaces, continuously dipping the water-based resin to connect the resin on the adjacent dentofacial surfaces with the positioning main body 7, volatilizing moisture to obtain a formed supporting side wing 8, or building a reinforcing rib between the resin on the adjacent dentofacial surfaces and the positioning main body 7, continuously dipping the water-based resin to connect the resin on the adjacent dentofacial surfaces with the positioning main body 7, wrapping the reinforcing rib, and volatilizing the moisture to obtain the supporting side wing 8 internally provided with the reinforcing rib;
6) the fixing bolt 3 is disassembled, then the base platform 2, the positioning main body 7 sleeved outside the base platform 2 and the supporting side wing 8 are integrally taken out, then the whole body is moved to an implant with a missing tooth position in the oral cavity of a patient, and the position of the positioning main body 7 is adjusted, so that when the bottom surface 80 of the supporting side wing 8 is matched with the jaw surface of the adjacent tooth with the missing tooth position in the oral cavity of the patient, the base platform 2 is positioned at a correct installation position;
7) keep the internal wall face 70 of location main part 7 and the crown connection section 21 surface of base station 2 to mutually support, keep supporting the bottom surface 80 of wing 8 and patient's oral cavity to lack the adjacent dentognathic face of tooth position to mutually support simultaneously, pass fixing bolt 3 the shoulder hole 24 of base station 2, reinsert in the threaded hole of implant substitute 6, screw up fixing bolt 3 and make it realize threaded connection with the threaded hole after that to accomplish the installation of base station 2 on the implant, take out location main part 7 and support wing 8 at last.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
