Abstract:

Objective  To explore the effects of mandibular implant junction on the growth of immature bone. Methods  Eight Beagle dogs were randomly divided into three groups: control, unjunction and junction. Twelve implants were produced on the mandible of unjunction experimental group and junction experimental group. At three months after implanting, radiographic examination was performed. Results  Three months after implanting, all implants were integrated with bone. None implants was mobile or got off. Radiographic examination demonstrated that the bone lose difference was no significant in junction and unjunction group. Conclusion  Mandibular implant connection wasn′t effect on the growth of bone.
