Effects of artificial bone particles in maxillary sinus augmentation in rabbits:An experimental study / 实用口腔医学杂志

ABSTRACT

Objective: To compare JGW with autogenous bone when used as grafting material in maxillary sinus floor augmentation.Methods: A study was conducted by performing a bilateral maxillary sinus floor augmentation with autogenous bone and JGW(Jin Gu Wei,Golden Bone,bone substitute,Shanghai Xiaobo Tec.) on rabbits.The process of bone formation was evaluated during different periods by imageology and histomorphology methods.Results: At 2nd week the gray scale of JGW was very lower than that of autogenous bone,but no significant difference was found at 12th week.The number of osteoblasts decreased with the time,no significant difference was found at 12th week.The degradation of JGW was relatively faster.Conclusion: JGW is feasible in maxillary sinus floor augmentation.
