Aim This was to access the changes in masticatory efficiency and patient satisfaction of single implant supported mandibular overdentures (SIMO) vs conventional complete dentures (CCD).
Method We performed a literature search of published articles in MEDLINE database via PubMed, Google Scholar, Cochrane Central Register Of Controlled Trials (Central), from July 2020 till September 2020. We searched for studies in English without time restrictions, including articles since 1997 upto 2020. Inclusion criteria in our study were randomized controlled trial (RCT) evaluating masticatory efficiency or patient satisfaction with SIMO and CCD, prospective studies with before-after comparisons, prospective studies with at least 10 SIMO patients. Studies must include conventional denture wearers as an active comparator (control group), and single-arm prospective studies must assess patients treated with conventional dentures as the baseline treatment. Masticatory efficiency or patient satisfaction had to be assessed in the study. Exclusion criteria were studies in languages other than English, Reviews, case reports, abstracts, editorials, letters, animal experiments, historical reviews and in vitro studies.
Result We followed the PRISMA guidelines. A total of 14 studies over the past three decades met the inclusion criteria for full text reading and all 14 were included for further analysis. Statistical analyses were performed using Review Manager version 5.3 (The Nordic Cochrane Centre, Copenhagen, Denmark).
Conclusion Within the limitations of this study, it can be concluded that a considerable improvement was found with SIMO in masticatory efficiency and patient satisfaction, especially for maladaptive CCD wearers. It could be considered as a future paradigm for treatment of edentulous mandibles. Further studies designed with standardized measuring protocols, large sample size and long-term follow-ups are indicated to add evidence and support for the indication of SIMO.
