Introduction: Socket preservation enhances healing and reduces bone loss during healing of extraction socket. Objectives: To assess the effect of bio-absorbable collagen wound dressing (CollaTape®; Zimmer) on the of healing of extraction sockets in rabbits when applied alone and combined with IngeniOs Beta tricalcium phosphate (β-TCP) synthetic bone particles. Materials and methods: Sixteen rabbits were included in this study in which lower left first premolars were extracted and then divided into three groups including: Control group (4 animals) in which the sockets were left for normal healing, Collatape group (the sockets were closed with CollaTape collagen wound dressing alone) and IngeniOs β-TCP group (6 animals) in which the sockets were filled with synthetic bone particles and were closed with CollaTape collagen wound dressing. Euthanasia were done 2 and 6 weeks respectively. Socket healing was examined and evaluated histologically and analyzed histomorphometrically. Results: At 2 weeks of healing, it was observed in all groups that the sockets were filled with newly formed woven bone. The percentage of newly formed bone was lowest in control group followed by Collatape group while β-TCP group showed highest values. At 6 weeks healing period, the socket entrance was sealed with compact bone and the rest of the socket was filled with trabecular bone. β-TCP group showed the highest values of the percentage of the formed bone. Conclusions: It was confirmed that IngeniOs β-TCP enhances bone formation during socket healing and could be used for socket preservation
