Marginal Bone Level Changes and Oral Health Impact Profile (14) Score of Smokers Treated by Mandibular Mini Implant Overdentures: A 5-Year Follow-up Study.

objectivesStudies 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

methodsTwenty-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

resultsThe mean of the bone height changes showed a significant difference between 1-month data and all other evaluation intervals while no significance was calculated among other evaluation intervals. Bone loss of the mini implants placed anteriorly was less than those placed posteriorly with a statistically significant difference. A significant reduction in the OHIP-14 score levels was observed between pretreatment and both 1 and 5 years of treatment. No significance was seen between the first and fifth year after treatment.

conclusionMini implant overdenture could maintain satisfactory marginal bone level changes and oral health quality of life for patients with smoking habit after 5-year follow-up period.
