Purpose: To investigate the effect of tooth/implant -supported restoration.
Methods: Twenty patients were divided into 2 groups randomly. In the group A, ten patients received tooth/implant supported restoration and in the group B, ten patients received implant only restoration. The absorption rate of bone tissue, the change of soft tissue, the survival rate of the implant and the degree of patients' satisfaction were collected during the follow-up three years after treatment. The data was analyzed by SPSS 14.0 software package for Student's t test.
Results: The survival rate of the implants in the 2 groups was 100%. The bone tissue absorption rate in the group A was (1.0±0.28)mm and (1.0±0.23)mm in the group B, the difference was not significant(P>0.05). No significant difference was found in bone absorption, change of soft tissue and degree of patients' satisfaction.
Conclusion: Short-term success can be achieved to use tooth/implant-supported restoration for implant without any physical mobility.
