Streszczenie
Protezy typu overdenture są jednym z rozwiązań gwarantujących funkcjonalną i estetyczną rehabilitację pacjenta bezzębnego. Zastosowanie elementów retencyjnych wpływa na poprawę retencji i stabilizacji protezy, zwłaszcza w przypadku znacznych zaników podłoża protetycznego. W pracy dokonano przeglądu piśmiennictwa dotyczącego: zastosowania protez typu overdenture i elementów retencyjnych mocujących protezę na podłożu u pacjentów bezzębnych i z uzębieniem resztkowym, a także czynników wpływających na sukces leczenia.
Abstract
In the case of edentulism and difficult denture foundation area overdentures can be one of the solutions for functional and aesthetic prosthetic restoration. Using the overdenture attachments has an impact on improvement of retention and stabilisation of dental prosthesis, especially in the situation when dental foundation area is atrophic. The article shows the literature review of using overdentures and retentive attachments in the treatment of edentulous patients, patients with residual teeth and factors influencing success of treatment.
