摘要： 目的:不同牙周生物型对美学区同期行引导骨再生术(Guided Bone Regeneration,GBR)的延期种植的红白美学效果的影响。方法:通过缺牙区同名牙或临近牙牙周探诊目测法随机分为A组:薄龈生物型15例;B组:厚龈生物型17例,共32例患者。种植体植入前进行牙槽嵴顶和牙槽嵴顶下3 mm牙龈厚度的测量,基台带入前再次进行相同位置牙龈厚度的测量;上部结构完成后的0、6、9月,修复及正畸医师对红色美学区进行红色美学指数(Pink Esthetic Score,PES)和牙冠的白色美学指数(White Esthetic Score,WES)分别评分。结果:A组:术前种植区牙槽嵴顶下3 mm牙龈厚度(1.39±0.34 mm)＜1.5 mm,P＞0.05,差异无统计学意义;B组:术前术后种植区牙槽嵴顶下3 mm牙龈厚度均＞1.5 mm,P＜0.05,统计学差异明显。A、B组牙槽嵴顶牙龈厚度在术前术后均＞1.5 mm,P＜0.05,统计学差异明显。A、B组两位点术前术后配对比较P＜0.05,有明显统计学差异。第0、6、9月PES评分:A组:为(9.90±0.99)、(11.53±0.82)、(10.77±0.77)。B组:为(11.03±0.80)、(12.32±0.64)、(11.59±0.61)。第0、6、9月WES评分A组:为(7.23±0.63)、(8.20±0.48)、(7.83±0.59)。B组:为(7.50±0.56)、(8.38±0.49)、(8.15±0.61)。B组的PES指数评分优于A组(P＜0.05)且组内0、6、9月统计学差异明显;WES评分A、B两组间无明显统计学差异,组内0、6、9月统计学差异明显。PES和WES存在明显相关性。结论:1)同期行GBR延期种植修复可以增加种植区牙槽嵴顶及牙槽嵴顶下3 mm的牙龈厚度;2)厚龈生物型患者较薄龈生物型患者在延期种植同期GBR的修复方式中较易获得良好的红色美学效果;3)不同牙周生物型患者在在延期种植同期GBR的修复方式后PES与WES存在正相关(r2=0.185)。

Abstract: Objective: To determine whether periodontal biological types influence the aesthetic result of delayed implantation underwent guided bone regeneration (GBR) in the aesthetic zone. Methods: A total of 32 patients were randomly enrolled. Through observation or periodontal probing, 15 cases with thin gingival biotype were included in Group A, and 17 cases with thick gingival biotype were included in Group B. The thickness of gingiva at the crest of alveolar and 3mm under the crest of alveolar was measured before implantation and before the abutment was connected. After the completion of upper structure for 0, 6, and 9 months, both pink aesthetic index (PES) and white aesthetic index of crowns (WES) were evaluated, respectively. Results: As to the thickness of gingiva at 3 mm under the crest of alveolar bone, for Group A, it (1.39±0.34 mm) was less than 1.5mm before implantation (P>0.05); for Group B, it was more than 1.5 mm before and after implantation (P<0.05). As to the thickness of gingiva at the crest of alveolar bone, for both Group A and Group B, it was more than 1.5 mm before and after implantation (P<0.05). There was difference between Group A and Group B before and after implantation (P<0.05). The scores of PES after 0, 6, and 9 months were: Group A (9.90±0.99), (11.53±0.82), (10.77±0.77), Group B (11.03±0.80), (12.32±0.64), (11.59±0.61). Group B was better than Group A (P<0.05) and there was significant difference among different time points within each group. The scores of WES after 0, 6, and 9 months were: Group A (7.23±0.63), (8.20±0.48), (7.83±0.59), Group B (7.50±0.56), (8.38±0.49), (8.15±0.61). There was no difference between Group A and B (P>0.05) and significant difference among different time points. There was significant correlation between both groups. Conclusion: 1) The delayed implantation underwent GBR can increase the gingival thickness at the alveolar crest and 3mm under the alveolar crest; 2) The patients with thick gingival biotype were more likely to acquire good red aesthetic result during the delayed implantation underwent GBR. 3) PES is positively related to WES in patients with different gingival biotype after delayed implantation underwent GBR (r2=0.185).
