Device for fixation of removable prosthesis on implants
The invention relates to medicine, namely to the dentist, and can be used to secure the full and partial dentures on the jaws. The technical result - without disturbing the aesthetics of the prosthesis, to ensure a reliable fixing of the jaws, to simplify the fastening system, to normalize the function of chewing and prolong the life of the prosthesis and implants. The device has an intraosseous implants and fixing elements made in the form of a cylindrical metal caps, mounted in the base of the denture. The prosthesis is fixed on the implants through the elastic plastic sleeve is pre-installed in caps, with a gap between the bottom cap and the end portion of the implant. 2 Il.The invention relates to medicine, namely to the dentist, and can be used to secure the full and partial dentures on the jaw.The urgency of the problem is that when severe atrophy of the alveolar part of the edentulous jaw dentures are not committed on the jaws.A prototype of the invention taken attachmenta the fixation of removable dentures with implant (severe O. N. Dental prosthesis on the implant, the displacement is (the side) of the head of the implant;chewing load is transmitted to the implant and creates pywikipedia time to implant;- matrix piece is placed in the base of the denture with rapid hardening the plastic in the oral cavity of the patient and may cause harmful effect on the mucous membrane of the mouth (burns, toxic effects);- matrix and Patricia part is locked in place when applying the prosthesis and transmit an additional load on the implant during removal of the prosthesis;the design is complicated to manufacture (requires casting of Patrick). The aim of the invention is to develop a device that would improve the fixation of removable prostheses in edentulous jaws, to simplify the fastening system, greatly reduce the pressure on the implant in the vertical direction.The essence of the invention lies in the fact that patients with complete absence of teeth, especially in the lower jaw, there are often unsatisfactory conditions for fixation and, consequently, operation, and dentures. The proposed device allows, without disturbing the aesthetics of the prosthesis, to ensure a reliable fixing of the jaws, to simplify the fastening system, to normalize the function of chewing and prolong the life of the Archpriest of intraosseous dental implant 1 with a removable head 2, the metal shell 3 and the elastic plastic sleeve 4. The sleeve 3 is intended for fixation of removable prosthesis (Fig.2) through the plastic sleeve 4 on the head 2 of the implant 1. The sleeve 3 (2 to 4) is mounted in the base of the denture 6, respectively, the number and location of the implant 1 in the bone tissue of the jaw 5 - Fig.2. The device does not load the implant in a vertical direction, as there is a gap 7 between the bottom of the cartridge 3 and the mechanical part of the head 2 of the implant 1, and the chewing pressure is transmitted to the tissue prosthetic bed only basis through removable prosthesis 6.Dental implant for fixation of removable prosthesis is used as follows.Install the implant 1 on the jaw in a known manner, however, they must be interconnected in parallel. After 2-3 months fabricate dentures and in the manufacturing process is introduced into the base of the prosthesis 6 caps (sleeves) 3, respectively the heads 2 of the implant 1 (Fig.2). The prosthesis is fixed to the head 2 of the implant 1 through elastic plastic sleeve 4, which are pre-set in sleeves 3 (Fig.2).Dental implant for fixation of removable prostheses used in 8 patients with complete absence of teeth and received positively is, teramae intraosseous implants and fixing elements, characterized in that it is equipped with a flexible plastic sleeve, the locking elements are in the form of a cylindrical metal cap is fixed in basis of the removable prosthesis, and the prosthesis is fixed on the implants through the elastic plastic sleeve is pre-installed in the caps with a gap between the bottom cap and the end portion of the implant.
FIELD: medical engineering.
SUBSTANCE: method involves producing an opening of diameter reaching 2 mm with diamond or hard alloy bore in adhesive cover after preparing abutment tooth and prosthesis or widening already available perforation also to diameter of 2 mm. The prosthesis is set on the abutment tooth and place is marked for creating and directing pin-canal in the area of cutting one-third of the frontal abutment tooth or in the lateral abutment tooth equator area. The pin-canal direction is to correspond to path for introducing the prosthesis. The pin is screwed-in with screwdriver and holder to a depth of about 2 mm into dentin. The prosthesis is set on the abutment for making control. The pin is filed-off to adhesive cover layer after having fixed the prosthesis on composition cement.
EFFECT: prolonged service life; high functional value.
