中文摘要 | ITI植牙系統主要特色是設計給一階段非埋入式植體手術之用。研究報告顯示臨 床效果及軟組織和植體周圍復原型式和傳統埋入式兩階段植入手術相當。而植體合併引導骨 再生術臨床上很廣泛使用在骨缺損較大的區域、骨開裂、骨開窗或齒槽骨不足以增加骨量。 本例報告的患者,左上顎缺第二小臼齒、第一大臼齒和第二大臼齒,左下顎缺第一大臼齒和 第二大臼齒,使用ITI植體重建其咬合恢復其咀嚼功能,並且臨床追蹤兩年。上顎齒槽骨和 鼻竇腔底部垂直骨量不足,使用osteotomes法植入植體。下顎植體植入後近冠部之鈦噴漿 裸露開裂,缺損部位放入脫鈣冷凍乾燥骨並覆蓋不可吸收再生膜,採埋入式兩階段處理。半 年後手術取出再生膜,缺損已被硬組織填滿。組織切片的結果顯示有新骨產生,脫鈣冷凍乾 燥骨顆粒被新長出的織狀骨圍繞兩者界面接合很好,周圍的結締組織沒有發炎現象。贗復完 成後病人持續接受維持治療一年後效果良好,病人沒有任何不舒服的感覺,對於咀嚼功能恢 復感覺滿意。 |
英文摘要 | The ITI implants system is designed for one-stage, non-submerged operation. Many studies demonstrated that the clinical results and healing response between implants and surrounding soft tissues compared with two-stage, submerged implants are similar. Guided bone regeneration has been extensively applied in the areas where large bone defect, ridge insufficiency, dehiscence or fenestration were noted. Our patient missing upper left second bicuspid, first and second molars, lower left first and second molars was placed with ITI dental implants to restore chewing function and has been followed for one years after complete prothesis. ITI implants using osteotome technique were placed in the upper arch. ITI implants using decalcified freeze-dried bone allograft (DFDBA) and Gore-Tex membrane were placed and submerged in the lower arch. Flap surgery was performed six months later to remove membrane and the regenerated hard tissues surrounding the healing cap was removed for tissue biopsies. Biopsy result revealed that DFDBA particles were surrounded by woven bone. Due to good home care and regular recall, no discomfort was noted and the patient was satisfied with the implants during the one-year follow-up. |
