A composite resin as an implant material in bone. Histologic, radiologic, microradiologic and oxytetracycline fluorescence examination of rats.

The potential of a bis-GMA composite resin as implant material in bone is evaluated. The material is claimed to have mechanical and physical properties superior to those of the bone cements used today. A groove made in the cortex of the tibia in 18 rats was filled with bis-GMA, while a similar groove was left empty in the contralateral tibia. The reaction of the bone to this material was evaluated by histologic, radiologic, microradiographic and OTC-fluorescence methods. The material was well tolerated by the bone; after 1, 3 and 6 weeks no reaction to the material was observed.
