中文摘要 | 針對下顎後牙缺牙區的植牙考量,殘留骨脊的舌側凹陷為臨床常見的解剖構造,其凹陷程度和角度是植牙的重要風險因子,若僅考慮復形位置而忽略解剖構造的限制,可能造成嚴重的術後併發症。本研究使用錐狀束電腦斷層測量分析的位病患之下顎舌側凹陷的相關數值,並以統計方式分析缺牙時間對舌側凹陷骨脊各數值的影響,以提供臨床植牙醫師在解剖構造外時間面上的考量。本研究除提供植牙醫師於具有舌側凹陷骨脊植牙的重要參考依據外,結果也顯示缺牙時間愈長齒槽骨脊寬度將愈小,但齒槽脊高度和凹陷處寬度則不受影響,缺牙時間愈長愈可能有較窄的骨脊寬度,故為下顎具凹陷骨脊者之重要風險因子,其他重要風險因子也包括性別因素、較後方牙位等,均需要完整且謹慎的術前評估,以減少下術後牙區植牙之風險。 |
英文摘要 | The presence of lingual concavity is common in the mandible and the angle and degree of it can be critical risk factors for implant placement in the posterior mandibular regions. Restoration-oriented implant position without considering underlying anatomic limitations such as lingual concavity may result in severe post-surgical complications. The aims of this study records not only the clinical parameters related to the lingual concavity and the edentulous ridge by cone-beam computed tomography (CBCT) in 43 patients, but also statistically analyzes the relationships between tooth missing time and the related clinical values. Results show the effects of tooth missing time, besides anatomical limitations, on implant placement. Our study also shows that information of the mandibular lingual concavity is important for implant placement in the posterior mandible, and longer tooth missing time leads to narrower alveolar width. Results also reveal that female, more posterior tooth sites, longer missing period are potential risk factors and require more comprehensive and cautious assessment before implant placement to prevent surgical complications in the mandibular posterior regions. |
