| Objective:Comparing the clinical effects of GBR with two different biofilm at oral implant operation.Methods: Sixty implants were placed in sixty single tooth missing patients with bone defects in the implantation area and simultaneous guided bone regeneration.All the subjects were randomly divided into experimental group and the control group(n=30).Bone defects were repaired by guided bone regeneration technique with CTi-mem custom titanium mesh and the Heal-all oral biofilm respectively.Panoramic radiographs were taken to observe the amount of new-formed bone tissue and adverse reaction rate of the two groups was compared.After 1 year follow-up,the success rate of two groups was compared.Results:The amount of new-formed bone tissue and adverse reaction rate of the two groups was no statistically significant(p>0.05).The success rate of implant restoration was 100% during the follow-up period of one year.In large area bone defect,the experimental group showed more satisfactory bone regeneration effect.Conclusion:Clinical effects of CTi-mem custom titanium mesh and the Heal-all oral biofilm are satisfied on guided bone regeneration in dental implant.In large area bone defect,the experimental group showed more satisfactory bone regeneration effect,which is well deserved the clinical promotion. |
