Abstract:

The aimof this study is to investigate the effect and complication of immediate implantation of particulate hydroxy2 lapatite artificial bone after teeth extraction.Methods : Particulate hydroxylapatite artificial bone was implanted into 65 extraction sockets after teeth extraction. All patients were followed up until 3 months after the operation. They are examined with clinical ex2 amination and X- ray examination to observe the effect and complication of the implantation operation.Results :The wound healed well in all cases without any complication. Compared to the alveolar ridge before teeth extraction , and the height of the alveolar ridge after teeth extraction didn’t decrease. Conclusion : Implantation of particulate hydroxylapatite artificial bone after teeth extrac2 tion could maintain the height of the alveolar ridge and reduce the complication of teeth extraction. It would be helpful for the fol2 lowing prosthetic restoration. The immediate implantation of artificial bone is therefore needed further study.
