Effect of conversion to implant‐assisted removable partial denture in patients with mandibular Kennedy classification Ⅰ: A systematic review and meta‐analysis

Abstract

Objective This review evaluated the change in treatment outcomes after conversion from conventional removable partial denture (RPD) to implant‐assisted removable partial denture (IARPD). The patient‐reported outcome measures (PROMs), objective parameters for evaluation of functional performance, and biological and mechanical complication were evaluated. Materials and Methods This systematic review was based on the Cochrane review methodology and followed the criteria of the preferred reporting items for systematic reviews and meta‐analyses (PRISMA). We searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, Web of Science, and Scopus up to April 3, 2019. After the initial search, additional electronic and hand searches were performed to identify further studies, ongoing studies, and gray literature, without restrictions on language, year of publication, or publication type. Results In total, 6,544 non‐duplicate articles were identified, and 31 were eligible for full‐text search. Finally, 19 publications based on 13 independent studies were selected. In the meta‐analysis, general patient satisfaction was significantly increased (p < .05), and the improved mastication was remarkable oral function. In oral health‐related quality of life, the oral health impact profile score was significantly improved, and improvements of physical pain and psychological disability were prominent (p < .05). Masticatory performance was improved in terms of maximum bite force, active occlusal contact area, and mandibular jaw movement (p < .05). The weighted mean survival rate of implants was 96.60%. Conclusions After conversion from conventional RPD to IARPD, the PROMs and masticatory performance significantly improved in partially edentulous patients under mandibular Kennedy classification I.

Bite Force in Elderly with Full Natural Dentition and Different Rehabilitation Prosthesis

“…IRO prostheses made it possible to download occlusal forces that occurred directly on the bone, without causing any pain. Overdenture stabilization improves MBF and masticatory function in our patients, as reported by other authors [ 7 , 15 , 30 , 35 , 39 ] and promotes masseter thickness enlargement [ 35 ].…”

Masticatory performance and other oral functions in community-dwelling elderly patients without posterior occlusal support by natural teeth

“…A limitation of this discussion, in addition to the statistical differences in age, is that the detailed distribution of the remaining teeth is not analyzed. In this study, although patients who were rehabilitated with implants including implant-assisted RDPs were excluded, previous studies demonstrated that the conversion of Kennedy classification by implant placement was an effective method to improve occlusal condition from the clinical point of view [25,26]. The analyses with consideration of Kennedy classification and RDP designs can demonstrate more meaningful results, although more patients are necessary.…”

The Effect of Patient Specific Factors on Occlusal Forces Generated: Best Evidence Consensus Statement

“…74 An SR of partial mucosal borne prostheses supported by implants and meta-analysis conducted of 13 studies (n = 257) indicated that masticatory performance was improved in terms of maximum bite force, active occlusal contact area, and jaw movement. 75 The location of occlusal force in the dentate arch has been shown to progressively increase toward the molar teeth with maximum occlusal force correlating well with the amount of occlusal contact area. 76 Edentulous subjects have reduced occlusal force generation in comparison to those dentate subjects.…”

“…The maximum bite force was slightly higher (3.0%) but significantly higher on the dentate side of the arch 74 . An SR of partial mucosal borne prostheses supported by implants and meta‐analysis conducted of 13 studies (n = 257) indicated that masticatory performance was improved in terms of maximum bite force, active occlusal contact area, and jaw movement 75 …”
