Abstract　： This study assesses the impact of bone ridge height on masticatory performance following treatment with a mandibular conventional denture (CD) or implant-assisted overdenture (IOD). Evaluation of masticatory performance (MP) in 63 participants was made with original complete dentures and 6-months after treatment completion with new dentures, 25 with a mandibular CD and 38 with a mandibular IOD. Mandibular bone height at the mandibular symphesis was determined on lateral cephalograms to provide subgroups of low, moderate and high ridge height for both CD and IOD. ANOVA comparisons of mean change in performance after treatment with study dentures for the three bone height groups indicated significant differences between the CD and IOD with peanuts (p=0.05) and carrots (P=0.03). Post-hoc tests found significant mean differences between the CD and IOD with peanuts (p=0.008) and carrots (P=0.01) only in the low bone height group. The study indicated that treatment with a mandibular IOD may improve masticatory performance only in persons with a less than adequate mandibular ridge.
