Impact of smoking on marginal bone loss.

摘要: PURPOSE To compare marginal implant bone loss (MBL), survival, and radiographic evidence of success dental implants among smokers nonsmokers. MATERIALS AND METHODS Consecutive records 161 patients (aged 23 to 89 years, mean 57 years) treated with a total 646 between the years 1995 1998 were examined. Patients divided into 3 groups: nonsmokers, moderate smokers, heavy smokers. Tobacco exposure was calculated by cigarettes per day pack-years. Follow-up ranged from 1 7 (mean 3.8 years). Postoperative panoramic radiographs obtained before annually thereafter analyzed for MBL changes. The influence smoking other variables on at all sites. RESULTS Generally, had more than nonsmokers (0.153 +/- 0.092 mm 0.047 0.048 mm, respectively; P < .001). When each jaw examined separately, greater effect in maxilla mandible (0.158 0.171 versus 0.146 0.158 Furthermore, maxilla, greatest amount (0.1897 0.1825 mm), followed (0.123 0.156 mm) (0.0460 0.070 (P In mandible, there no distinction both Only failed; cumulative survival rate 99.5%. Overall 93.2%. Nonsmokers higher (97.1%) (87.8%) CONCLUSIONS This study demonstrated relationship habits. A incidence found group, this pronounced maxilla.
