Mandibular implant‐supported removable partial denture with distal extension: a systematic review

Abstract

The aim of this article is to investigate patient satisfaction, survival rate of implants, and prosthetic complications or maintenance for rehabilitation with removable partial dentures associated with implants in mandibular Kennedy class I and II cases. A systematic literature review was conducted by three independent reviewers including articles published from January 1981 through September 2011. Medline and Cochrane Library electronic databases were used in addition to hand searching to assess clinical outcomes for mandibular implant-supported removable partial denture with distal extension. This review yielded 1751 records that were narrowed down to 5. The studies revealed implant survival rates ranging from 95% to 100% with one failure reported of 98 implants. The removable partial dentures associated with implant in mandibular free-end arches showed some complications and need of repair for relining, pitting of the healing abutment, replacement of resilient component of the attachment, damage in framework, screw loosening and damage in acrylic denture base. Patient satisfaction was evaluated through a five-point questionnaire, and results ranged between 4.12 and 5.0, considering 1 as the least favourable situation. The literature review showed increase in patient satisfaction and high survival rates of implants associated with mandibular removable partial dentures with distal extensions. However, some complications and need of prosthetic repair were reported. Although this treatment approach could represent a low-cost and beneficial rehabilitation for free-end mandibular ridges, the lack of controlled and randomised well-designed clinical trials suggests further studies with more representative samples to validate the outcomes of this treatment modality.

Mastication Improvement After Partial Implant-supported Prosthesis Use

“…Several prosthetic options are available to restore chewing function in patients with missing teeth (Abt et al, 2012;de Freitas et al, 2012). However, few studies (Kapur, 1991;Liedberg et al, 2004) have determined the effects of prosthetic treatment on mastication in partially edentulous patients, and their findings are controversial.…”

An examination of the cumulative survival rate of narrow-diameter dental implants in the mandibular molar region: a retrospective cohort study

“…However, implant treatment with GBR imposes greater physical, mental, and financial burdens on patients because it is a surgically invasive procedure [15,16]. Therefore, in this study, we investigated the survival rate of narrow-diameter implants in the mandibular molar region.…”

Complication and management of implant-assisted removable partial denture with distal extension: a clinical report

“…Considering complications such as pitting corrosion of healing abutment, screw loosening and fractures, periodic recall appointments should be arranged. 7,11 At 18 months recall appointment after delivery, the wear of healing abutment was observed.…”

“…5,6 Although several retrospective ISRPD studies have shown a high survival rate of implant, some mechanical complications can occur. de Freitas et al 7 reported that ISRPD had a high success rate ranging from 95 -100% and good patient's satisfaction but showed several complications such as pitting of the healing abutment, replacement of resilient component of the attachment, damage in framework, screw loosening and damage in acrylic denture base. This clinical report describes the mechanical complication of ISRPD.…”
