植體區採用口內自體骨塊移植之垂直骨嵴增進術-病例系列報告

Implant Site Development Using Intraoral Autogenous Bone Block for Vertical Ridge Augmentation-Case Series

摘要


植牙前植體區塑型,有利於將較理想尺寸的植體種植在較理想的位置,儘可能的符合植牙後補綴物重建的需求。有許多關於下顎骨自體骨塊在水平向植體區塑型的應用。相對而言,關於下顎骨自體骨塊在垂直向植體區塑型應用的臨床研究較少,而且多侷限於病例報告與病例系列。文中我們提出四個因嚴重牙周病破壞或嚴重植體周圍炎而造成後牙區嚴重齒槽骨嵴缺損的病例,運用自體骨塊及可吸收性在生膜垂直向植體區塑型。其中,最長時間的回診為功能性載重後第三年的追蹤,根尖X光片所顯示齒槽骨高度穩定,植體周圍牙齦無發炎,且後牙咬合功能良好。(臺灣牙周醫誌,20(3):212-226,2015)

並列摘要


Staged approach ridge augmentation can be conducted for optimized implant placement and allows ideal implant restoration. In this context autogenous block grafts have been used for lateral ridge augmentation. However, clinical research with respect to vertical ridge augmentation using block grafts remains limited and only consists of case reports and case series. We reported four cases that were diagnosed as severe periodontitis or periimplantitis and had resulted in severely mandibular atrophy. An intraoral autogenous bone block and resorbable membrane were used for vertical augmentation. The postoperative courses were uneventful. The post-functional loading at the 3-year follow-up showed stable marginal bone heights and healthy peri-implant mucosa with good chewing function. (J Taiwan Periodtontol, 20(3):212-226, 2015)
