An Innovative Meta-Systematic Review into the Landscape of Literature and the Concluding Evidence on the Quality of Life of Patients Using Two Implant Supported Mandibular Complete Denture Prosthesis

Abstract

Aim: The aim of this systematic review is to analyze the existing evidence on the quality of life of patients completely edentulous in the mandible. Materials and Methods: A search questionnaire was formulated using population intervention comparison outcome (PICO) analysis, and a comprehensive search was initiated in PubMed Central, Medline, Cochrane, and Google Scholar databases for the related topics. Manuscripts published till December 2019 were included in this review. Out of the 63 articles obtained from searching all databases, 27 studies were excluded based on the title and abstract. Out of the remaining 36 studies, 12 were excluded based on the inclusion and exclusion criteria of our interest and 24 were included on the basis of core data. Results: One review author identified randomized trials meeting inclusion criteria for this review. Two review authors extracted data and assessed study quality. The oral health-related quality of life in completely edentulous mandibular patients wearing implant-supported overdentures was better when compared to conventional tissue-supported complete denture, and a minimum two implant-supported mandibular complete denture has sufficient improvement in oral health-related quality of life. Conclusion: There are about more than 170 reviews and clinical trials that have been published in support of the same for the past two decades. Thus, the clinicians may not be tempted in placing additional implants in well-formed mandibular edentulous ridges. To enhance the understanding of mandibular implant overdenture treatment, clinicians must scrutinize the existing evidence and formulate a protocol by striking a balance between efficient and evidence based treatment.
