Tooth implant-supported removable denture: a systemaric review


Purpose: The aim of this systematic review is to verify whether tooth-implant supported removable dentures (TISRD) can really be proposed to patients as a successful alternative to traditional prosthetic therapy. Methods: This systematic review was carried out following the PRISMA guidelines and the studies were selected by PubMed and Scopus. The keywords were “tooth-implant connection,” “removable denture,” “removable dental prosthesis,” “tooth and implant supported removable dentures,” “partial dentures,” and “overdenture.” The outcomes sought in the potentially eligible studies were the survival rate of TISRD, the patient satisfaction, presence of biological and technical complications; furthermore the bias risk assessment was performed. Results: Out of the 3108 citations found, 19 studies met the inclusion criteria. In the included studies the enrolled participants were 615, the implant abutments were 1118 and the residual teeth were 601. The behaviour of abutments was examined for a time range between 6 and 180 months. The survival rate of TISRD ranged between 91.82 and 100%; as for complications, none of the authors reported intrusion and the most frequent biologi. Clinical significance: The tooth-implant connection seems to be an alternative and beneficial treatment for the rehabilitation of partially edentulous patients, however the evidence remains slight and unclear due to the shortage of controlled and randomized clinical trials. Therefore, further studies with a higher level of evidence and more representative samples are need.
