The use of polyetheretherketone for the manufacture of removable implant dentures

INTRODUCTION: The industry of temporary prosthetics for dental implantation in the postoperative period at the present stage of the development of dentistry has achieved significant results. However, up to now, there are still cases of insufficient effectiveness of temporary prosthetics, which is expressed in a reduced service life and a violation of the retention of temporary structures, the need for a relatively large number of corrections of their basis, as well as inflammatory and atrophic changes in the mucous membrane of the prosthetic bed and loss of bone tissue in the jaws in the projection of the mechanical pressure of the prosthesis. AIM: To determine the effectiveness of the use of polyetheretherketone for the manufacture of immediate prostheses based on temporary dental implants. MATERIALS AND METHODS: Dental implants in the upper jaw were installed in 76 patients with a diagnosis of full absence of teeth. For temporary rehabilitation for the period of osteointegration, temporary implants were installed in the amount of 2 pieces and temporary removable dentures were made. RESULTS: The use of polyetheretherketone revealed a 25% decrease in dentures breakdowns, an increase in the number of temporary implants viability by 37.5%, and a decrease in bone tissue atrophy by 19% to 22%. CONCLUSIONS: It is advisable to use polyetheretherketone for the manufacture of removable implant dentures.
