This report describes a treatment modification for a patient presented with severely resorbed bilateral edentulous posterior mandible and mobility of the anterior teeth. There was less than 8 mm of bone between the crest of the alveolar ridge and the mandibular canal as revealed by radiographic examination. A modified technique for inferior alveolar nerve lateralization (IANL) in conjunction with ridge expansion was performed using threaded bone expanders, which allowed for better primary stability and placing longer implants. A total of four postextraction implants were in the anterior region of the mandible. The mandible received a total of nine one-piece implants to allow for immediate nonfunctional loading. The definitive ceramometallic prosthesis was delivered 3 months postoperatively. The 10 years clinical and radiographic assessment showed minimal bone resorption around osseointegrated implants. One-piece implants showed great success rate and minimal bone resorption following the modified technique of IANL and immediate implantation.
本报告描述了对一名双侧下颌后牙严重吸收且前牙松动患者的治疗改良。影像学检查显示,牙槽嵴顶与下颌管之间的骨量不足8毫米。采用螺纹式骨扩张器进行了改良的下牙槽神经侧方移位术(IANL)并结合牙槽嵴扩张,这使得种植体获得了更好的初期稳定性并能植入更长的种植体。下颌前部共植入了4颗拔牙后种植体。下颌总共植入了9颗一体式种植体,以实现即刻非功能性负载。术后3个月交付了最终的烤瓷金属修复体。10年的临床和影像学评估显示,骨结合种植体周围的骨吸收极少。采用改良的IANL技术和即刻种植后,一体式种植体显示出很高的成功率和极少的骨吸收。
