Average rate of ridge resorption in denture treatment: A Systematic Review

Abstract

Purpose: To clarify the rate of posterior residual ridge resorption (PRRR) in different denture treatments and the factors that can affect PRRR. Study selection: A bibliographical electronic search was conducted on MeSH, Web of Science, and Ovid databases. Hand searching was also conducted. Longitudinal studies recording the average rate of PRRR in the mandible were included. The effect size was calculated based on the mean rate of PRRR with standard deviation and group size. The random-effects analysis was used to perform meta-analyses across qualified studies. Results: A total of 2245 eligible studies were collected from the MeSH, Web of Science, and Ovid databases and hand searching. In the end, 19 studies met the inclusion criteria and were extracted. The average rate of PRRR in different mandibular denture treatments was assessed in this systematic review. The mean combined effect size was-1.05 ± 0.5 (95% confidence interval [CI]:-3.18-1.08) between four-implant overdentures and two-implant overdentures. The combined effect size was-0.01 ± 0.22 (95% CI:-0.93-0.82) between complete dentures and two-implant overdentures. Body mass index, number of dentures used, denture wearing habit, impression technique, artificial tooth material, and peri-implant bone resorption showed no significant effect on the rate of PRRR. Gender, denture material, and relining frequency showed a significant effect on the rate of PRRR. Conclusions: This review summarized different average rates of PRRR in mandibular denture treatments. Meta-analyses have reported that four-implant overdenture treatments can lower the rate of PRRR compared to two-implant overdenture treatments. However, there was no significant difference in the treatment effect between the complete denture and two-implant overdenture treatments.

Mandibular bone height changes in two different design concepts of four implant assisted overdenture

“…N. Pham et al (2021) [34] conducted a systemic review to clarify the rate of posterior residual ridge resorption (PRRR) in different denture treatments and the factors that can affect PRRR. Meta-analyses revealed that the 4-IOD treatment could lower the rate of PRRR compared with the 2-IOD treatment.…”

Current perspectives of residual ridge resorption: Pathological activation of oral barrier osteoclasts

“…More recently, Alsaggaf and Fenlon (2020) reported that excessive denture wearing for more than five years significantly increased residual ridge resorption compared to non-denture-wearing edentulous patients [110]. Furthermore, Pham et al reported in a systematic review that two implant-assisted overdenture treatments increased the rate of posterior residual ridge resorption compared to four implant-supported overdenture treatments, indicating that increasing mechanical pressure on the posterior edentulous gingiva might promote residual ridge resorption [111].…”

Using Denture Base For Local Treatment With Vit B12 Versus Parenteral Treatment – A New Approach

“…Dental arches lost to edentation can be artificially recreated in a way that is as personalized as possible, based on the scenario, goals, and treatment criteria that apply in the case of total edentation [11][12][13]. crosslinked polymerization using vitamin B12 as a template was used to optimize the structure of traditional 1 unIVersIty oF MeDIcIne anD PHarMacy Gr.t.…”
