Objectives Studies considered edentulous patients having smoking habit as a compromised oral condition. This research examined the value of using mini implant mandibular overdenture to maintain long-term satisfactory levels of oral health quality of life and marginal vertical bone loss.

Materials and Methods Twenty-nine edentulous patients with smoking habit received four mini implants in the mandible loaded by overdentures. The present study monitored patients radiographically for vertical bone loss after (1 month, 1, 3, and 5 years) of treatment. Patients were also evaluated by oral health impact profile 14 (OHIP-14) pretreatment and at 1 and 5 years of treatment.

Statistical Analysis Repeated measure analysis of variance with Bonferroni’s test as a post-hoc test was used to see the difference among time points. Independent sample t-tests were used to compare between anterior and posterior mini …
