Vol. 13 – Number 52 – 2022 NOTEBOOK OF CLINICAL DENTISTRY Case report Page 111-116 Conventional total prosthesis conversion in overdenture Andressa Lopes Barbosa Martins¹ Leonardo de Pádua Andrade Almeida² Tatiane Cristina Dotta² Valdimar da Silva Valente³ ABSTRACT Edentulism is a very common condition in the Brazilian population, therefore, there is a large confection of dentures. However, depending on the degree of bone resorption, it may become unstable, affecting the quality of life of the patients. In order to increase the retention and stability of these prostheses and reduce discomfort, rehabilitation through the installation of implants was popularized. Patient FMA, male, 65 years, total edentulous, reported having recently received full dentures for both arches. However, he revealed discomfort during function due to the small retentive capacity of his inferior prosthesis, since the alveolar ridge showed intense bone resorption. After evaluation, it was proposed to install two implants between the mentonian foramen for later integration to the prosthesis, turning it into an overdenture. 3.75 x 10.0 mm external hexagon connection implants were used. After 4 months, the male portions of the retention system employed (Oring) were threaded to the implant and the lower prosthesis adapted to capture the female portions at the base of the implant. Maintenance appointments were scheduled for oral hygiene assessment and control. The patient is satisfied with the use of implanted overdenture, especially by improving his chewing ability. The technique performed is a good alternative for conferring retention and stability, ease of execution, hygiene, and low cost, in view of the conversion of the prosthesis already used and the possibility of dispensing laboratory steps, since the capture of the capsule can be performed clinically.
