| 【】目的：研究观察美学区种植同期引导骨再生(Guided bone regeneration,GBR)术后骨厚度的变化量。方法：选取我院行上颌前牙植入种植体同时用GBR术增加骨量的上前牙缺失患者37例。采用锥形束计算机体层摄影技术(CBCT)分别测量所有患者术前、种植Ⅰ期(T1)、种植Ⅱ期(T2)、修复Ⅰ期(T3)及修复Ⅱ期(T4)后种植体颈根部以上1mm、4mm、7mm、10mm、14mm位点处的骨厚度,并分析其在不同时期同一位置的骨厚度变化情况。结果：术后种植区牙槽骨骨壁厚相比于术前明显增大；T2时种植区唇侧骨壁厚度与T1时相比,在S1、S2、S3、S4位点处均明显减小(P＜0.05),上述差异均有统计学意义(P＜0.05)。在T3与T4时在各位点的种植区唇侧骨壁厚度相比较,差异无统计学意义(P＞0.05)。结论：美学区种植同期GBR术后能有效增加上前牙缺失患者的牙槽骨骨量,减小种植术后种植区唇侧骨壁厚度,同时保持修复后骨改建的稳定性,保证其美学效果。 |

| 【】Objective: To observe the changes of bone thickness after bone regeneration guided (GBR)by the same period in the aesthetic area.Methods: In our hospital, maxillary anterior tooth implant and GBR increase bone mass forward in 37 cases of patients with missing teeth. Using the cone beam computed tomography (CBCT) were measured in all patients before, planting 1 (T1), planting stage II (T2), after primary repair (T3) and phase II (T4) restoration planting body at the root of the neck more than 1mm, 4mm, 7mm, 10mm, bone thickness at the site of 14mm and analysis its in different periods of the same position bone thickness change situation.Results: Postoperative planting area of alveolar bone wall thickness compared to preoperative increased significantly; T2 planting area LIP lateral bone wall thickness and T1 when compared to, in the S1, S2, S3, S4 sites were significantly decreased (P < 0.05), the differences were statistically significant (P < 0.05). In T3 and T4 in each of the lip of the planting area lateral bone wall thickness compared, the difference was not statistically significant (P > 0.05).Conclusion: Aesthetic cultivation period GBR can effectively increase the anterior edentulous patients alveolar bone and implantation decreases after cultivation of lip lateral bone wall thickness, while maintaining bone remodeling after the restoration of stability, to ensure its aesthetic effect.#$NL【Keywords】Aesthetic area; Implant surgery ; Guided bone regeneration; Bone mass |
