植體周圍炎的處置：病例報告及文獻回顧
Management of Peri-Implantitis: Case Reports and a Literature Review
摘要
植體周圍炎是植牙後很常見的併發症，植體周圍骨頭修復的機轉與自然牙不同，針對螺紋部分也很難徹底清創，一旦周圍組織開始發炎便很容易加速其破壞。所以目前還沒有一致的標準來處理植體周圍炎，本文中分享兩個病例以手術方式介入治療植體周圍炎。兩名患者於植體接出後2~3年內發生植體周圍炎：一位以切除性手術的方式修整植體周圍骨頭的形態；另一位以再生性手術治療骨缺損。術後6~8個月兩位病人植牙周圍皆有探測深度改善，囊袋探測出血及化膿的現象皆有改善，伴隨牙齦萎縮及螺紋露出，發炎得到控制。對於植體周圍炎的病人，以手術方式積極介入可以早期解決局部性發炎的狀況，可以控制疾病的進展，但因螺紋露出造成清潔上的不容易，需要監控病人的口腔清潔及長期追蹤。

Peri-implantitis is a common complication after implantation. The histology and repair mechanisms of peri-implant tissue are different to those of natural teeth. Once the peri-implant tissue inflamed, it is not easy to halt the breakdown of peri-implant tissue; furthermore, the threads of the implant are also difficult to debride thoroughly. This article reports two cases where management of peri-implantitis by surgical intervention was carried out. We preformed osseous resective surgery on one case and carried out regenerative surgery on the other case. After 6 to 8 months, the clinical parameters and inflammatory signs of the patients had improved and this was accompanied by receded gingiva and the exposure of the threads. In those patient whose peri-implantitis cannot be controlled after initial therapy, surgical intervention seems to be a predictable option when managing peri-implant problems and controlling inflammation.
