The Observation of Bone Absorption of Buccal and Palatal Bone-wall with Bone Splitting Technique in Anterior Region of Maxilla
摘要
Abstract
Objective:To evaluate the clinical treatment effects of the absorption of buccal and palatal bone-wall by improved bone splitting technique.Method:20 patients with missing maxillary anterior teeth,the sufficient vertical bone height and the maxillary anterior alveolar ridge of 3-5 mm were enrolled in this study. 28 implants were placed using bone splitting technique ,bone substitute grafting and guide bone regeneration technique would be used. 28 implants were randomly divided into the observation group and the control group,each group had 14 dental implants. The bone split position in the control group was in the middle of the lip side and palatal side,while the bone split position in the observation group was 1 mm by palatal side. Two-stage operations were after 6 months,the bone of implants around and caculating the loss of bone wall height were observed.Result:The absorption of buccal bone wall was(0.77±0.11)mm and the absorption of palatal bone wall was(0.41±0.12)mm in the observation group. The absorption of buccal bone wall was(1.57±0.16)mm and the absorption of palatal bone wall was(0.34±0.11)mm in the control group. The difference of absorption in buccal bone wall between the two groups was statistically significant(P<0.05).The difference of absorption in palatal bone wall between the two groups was not statistically significant(P>0.05).Conclusion:The split buccal bone wall retained relatively more cancellous bone in the improved bone splitting technique,that effectively prevented further absorption of buccal bone wall.关键词
