Comparison in Dental Implant Survival Rate among Patients with Different Smoking Status
比較不同吸煙狀態患者的人工植牙存活率
摘要
Aim: There have been only a few studies on implant failure that focused on different smoking statuses. Thus, the aim of this study was to compare dental implant survival rates among patients with different smoking statuses. Materials and Methods: This retrospective study involved adults who underwent dental implantation between January 2003 and December 2016. The smoking statuses of patients at Stage I implant surgery was recorded as current smoker, former smoker (those who stopped smoking before implant placement), and nonsmoker (those who have never smoked). Implant survival rate was divided into survival, early implant failure before loading, and late implant failure after loading. There were four subgroups in dental implant therapy: implant site development using ridge preservation (RP subgroup), ridge augmentation due to ridge resorption before dental implant placement (RA subgroup), implant placement combined with sinus lift (SL subgroup), and implant placement combined with bone grafting (BG subgroup). Then, to compare implant survival rates in different implant surgical conditions among the three smoking statuses. Results: In the maxilla, there were significant differences in implant survival rate (p=0.002) and in three subgroups except for ＂RA subgroup＂ (p=0.03, 0.006, 0.001 in RP, SL, BG subgroups, individual). In the mandible, there was a significant difference in implant survival rate (p=0.0005); however, there was no significance in the three subgroups. Conclusions: The implant survival rate declined from nonsmokers and former smokers to current smokers. Smoking cessation can improve outcomes; thus, counseling on smoking cessation is suggested to be a part of dental implant treatment.

目的：研究不同吸煙狀態與人工植牙失敗的關聯研究很少。因此，本研究的目的是比較不同吸煙狀態的患者的牙科人工植牙存活率。材料和方法：本回顧性研究收集在2003年1月至2016年12月間接受人工植牙的成年人。在第一階段植入手術中，患者的吸煙狀態記錄為當前吸煙者、前吸煙者（植入放置前戒煙）和非吸煙者（從不吸煙）。人工植牙存活率分為生存、早期植牙失敗和晚期植牙失敗。在人工植牙治療包含四個子組：植牙前曾接受齒糟保留術子組，植牙前曾接受齒槽嵴重建術子組，人工植牙合併鼻竇提升手術和人工植牙合併骨移植手術子組。然後，比較不同組別下三種吸煙狀態的人工植牙存活率。結果：在上顎區，除“植牙前曾接受齒槽嵴保留術”子組外，不同抽菸狀態下的人工植牙存活率在三個子組中皆存在顯著差異。在下顎區，不同抽菸狀態下同樣也有顯著差異的人工植牙存活率，但是，在三個子組中沒有統計明顯差異。結論：人工植牙的存活率從“不吸煙者，戒煙者到吸煙者”呈下降趨勢。戒煙可以改善人工植牙的存活率，因此建議就戒煙問題提供諮詢，作為牙科植牙治療的一部分。
