Immediate implantation has the important advantages, as possibility to minimize of alveolar bone loss after physiological healing of tooth socket, decrease of surgical stages and terms of treatment. The purpose of our research was increasing of efficiency of immediate implantation in infected tooth socket.

Materials and methods: 19 screw implants were installed in tooth sockets with periapical/periodontal infection on 15 patients. 11 implants of them were included in experimental group and 8 were included in control group. In experimental group after extraction we used sterile ophthalmic ointment of 1% tetracycline. Then the sockets were washed by 0.9% NaCl solution.

Results: 6 implants in control group were lost. The remaining patients with 13 implants were examinated clinically and radiografically later 6 months. Stability of implants, full healing of sockets and osteointegration were observed.

Conclusion: Tetracycline can be use successfully in infected tooth socket at immediate implantation. This application can increase of efficiency of immediate implantation in infected tooth socket and decrease of number of potential complications.
