[Effect of implant junction on bone growth by X-ray analysis].

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.

[Effect of implantation and implant connection on craniofacial bone growth in Beagle dogs].

PURPOSE: To study the effects of implantation and implant connection on Beagle craniofacial bone growth. METHODS: Eight Beagle dogs were randomly divided into two groups: unconnection group (4 dogs) and connection group (4 dogs). Two implant were implanted respectively in the lateral maxilla and zygomatic bone in each dog, the contra lateral side was used as normal control. Two implant was connected in the connection group 1 month later. Student's t test was used to analyze the data using SPSS11.5 software package. RESULTS: In the unconnection group, the distance increased between implants along with craniofacial bone growth; In the connection group, the distance fixed between implants along with craniofacial bone growth. The craniofacial values revealed no significant differences in the two groups (P > 0.05). CONCLUSION: The effect of implantation is localized and no inhibition in development of craniofacial bone is noted.
