Introduction: Increasing bone quality and quantity in the areas with insufficient bone volume is a major concern among scientists. Ideal bone substitute materials should have osteogenicity, osteoconductivity, and osteoinductivity. Clinoptilolite offers bovine deorganified crystalline bone materials, the advantage of being very similar to human bone with regard to its pore morphology and crystalline structure. This study evaluated the effect of adding Clinoptilolite to Bio-Oss on the osseous regeneration and bone healing process using serial dual-energy X-ray absorptiometry (DXA).
Materials and methods: A total of 64 rabbits were anesthetized and a bone defect was created on both semi-mandibles. The rabbits were divided into four equal groups: A (Bio-Oss®); B (Bio-Oss® with 2% Clinoptilolite mixture); C (allograft); and D receiving no treatment. The bone healing response of animals was tested after 2, 14, 30, and 60 days.
Results: Statistical analysis showed significant differences at time intervals before 14 days between allograft and other groups (p < 0.05). In all the defects filled with the tested materials, bone formation was observed subjectively. At 30- and 60-day intervals, there were no significant differences between allograft and Bio-Oss with 2% Clinoptilolite group (p = 0.052 and p = 0.260 respectively) although it was significant in 2- and 14-day intervals.
Conclusion: Clinoptilolite (2%) can be used to improve the osteoinduction property of bovine deorganified crystalline bone material. Clinoptilolite can be suggested as a potential material added to bone substitute materials due to its porous structure and buffering capacity and adsorption of a number of serum components which aids the osseous regeneration and healing process.
