ABSTRACT
Objective To analyze the clinical effect of membrane guided bone regeneration technique combined with 3 I implant system in anterior dental implant.Methods 50 patients with anterior teeth missing were selected as the experimental group,they received membrane guided bone regeneration technique combined with 3 I implant system of dental implant.50 cases alone with 3 I implant system of dental implant were selected as the control group.The clinical data were retrospectively analyzed.The effects of the two groups were compared.Results Statistical results showed that the satisfaction of appearance and function had significant difference between the two groups(χ2 =6.73,P<0.05).The operation area of plaque index (PLI) (t=3.16,P<0.05),gingival sulcus bleeding index (MBI) (t=6.32,P<0.05),probing depth (PD) (t=2.63,P<0.05) had significant differences between the two groups.The thickness of the buccal tongue of the bone graft,and other indicators of the top of the implant to the top of the alveolar ridge showed significant differences between the two groups (t=17.65,P<0.05,t=8.48,P<0.05). Conclusion Using membrane guided bone regeneration technique and 3 I implant system combined application can improve dental implant in the anterior and the success rate of patients on the appearance and function of satisfaction after dental implant in the anterior,and to broaden the bone defect of anterior tooth planting the indication effect,it is worthy of clinical promotion.
