Development of Risedronate-Loaded Nano Capsules for Calvaria Healing in Rabbit

Abstract

Objective- Bone regeneration is a multifactorial phenomenon which contributed to several factors. It is reported that risedronate is effective for musculoskeletal diseases. The current study was to determine effectiveness of the risedronate-loaded nano capsules for calvaria healing in rabbit.Design- Experimental study.Procedures- 15 white adult male New Zealand rabbits were used. Four full-thickness skull defects were created in the calvarial bone. The first defect kept unfilled (control). The second was filled with nano risedronate capsules. The third hole was filled using an autogenous bone. The fourth hole was filled with nano risedronate capsules+ autogenous bone. At 4, 8 and 12 weeks after surgery, inflammation level, bone vitality grade, bone type and foreign body were determined.Results- According to the results, the most inflammation was found in control and the lowest in the nano autograft (p Conclusion and clinical relevance- The achieved results suggested have risedronate-loaded nano capsules have positive effects on bone formation and viability in calvaria healing in rabbit which be diminishing osteoclast activity improves bone formation.
