Assessment of primary stability of the implant placed in prepared infected extraction sockets

Abstract Background 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. Aim This study aimed to evaluate the clinical and radiological fate of immediately placed dental implants in debrided infected dentoalveolar sockets. Materials and methods 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. Results 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. Conclusion 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.
