The effect of smoking on early implant failure.

摘要: This retrospective study describes the effect of smoking on initial fixture failure before functional loading with fixed prosthetic restorations. Of 208 installed Branemark fixtures in mandible, only 1 failed (0.5%), and no detrimental survival could be detected. In maxilla, 10/244 (4%); 7/78 smokers 3/166 nonsmokers. The rate was 9% versus 1% nonsmokers statistically significant, despite fact that bone quality both groups comparable. Failed occurred 31% smokers, often excellent quality, long length or good stability. Only 4% had failures, most cases related to poor quality. It is concluded a significant although not important factor implants prior loading. Prospective studies are needed assess risk implant conjunction smoking. mean time, patients should informed adverse
