Dental conditions like periodontal, periapical pathologies and failed endodontically treated teeth are one of the commonest reasons for tooth removal. These conditions also contraindicate replacement of such teeth with immediate implant procedures.
This study aimed to evaluate the clinical and radiological fate of immediately placed dental implants in debrided infected dentoalveolar sockets.
A total of 24 implants were immediately placed into prepared infected sockets. The pathology at the receptacle sockets included subacute periodontal infection, perio-endo infection, chronic periapical infection, periodontal cyst and traumatic infected teeth. The treatment protocol emphasized on meticulous debridement of the infected sockets under pre- and post-surgical antibiotic therapy. Follow up of at least 24 months was done to evaluate the survival of implants.
At the end of follow up time period of 24 months, all 24 implants were stable with no signs of clinical mobility and infection. However, on radiological examination, crestal bone loss was observed during the osseointegration periods which settled at the level of first thread.
Survival of immediately placed implants in infected sockets is predictable and depends on the meticulous debridement of dentoalveolar sockets along with adequate pre- and post-operative antibiotic coverage.
牙周病、根尖周病变以及根管治疗失败的牙齿等口腔疾病是拔牙最常见的原因之一。这些情况也禁忌采用即刻种植手术来替换此类牙齿。
本研究旨在评估即刻植入清创后的感染牙槽窝内的牙种植体的临床及影像学转归。
总共24枚种植体即刻植入准备好的感染牙槽窝。种植体植入部位的病变包括亚急性牙周感染、牙周牙髓联合感染、慢性根尖周感染、牙周囊肿以及外伤感染牙。治疗方案强调在手术前后抗生素治疗的同时，对感染牙槽窝进行细致的清创。随访至少24个月以评估种植体的存留情况。
在24个月的随访期末，所有24枚种植体均稳定，无临床松动及感染迹象。然而，影像学检查显示，在骨结合期观察到嵴顶骨吸收，最终稳定在第一螺纹水平。
即刻植入感染牙槽窝内的种植体的存留情况是可预测性的，并且取决于对牙槽窝的细致清创以及充分的术前和术后抗生素覆盖。
