摘要:

目的   通过探讨牙周炎患者种植二期术后牙龈愈合达到稳定的时间,为牙周炎患者的种植修复提供指导。方法   选择29例已植入种植体(共60枚)并达到骨结合的牙周炎患者进行种植二期手术,术后测量每枚种植体的颊侧牙龈高度2次。术后第1周测量所有种植体的牙龈颊侧最低点,并设为初测点;其后按照观察时间随机分组,分为1、2、3、4组,每组15枚种植体,分别于术后第2、3、4、5周时进行第2次测量。观察4组第2次测量与初测点的牙龈变化量并进行统计学分析。结果   4组牙龈变化量分别为(-0.25±0.66)、(-0.04±0.52)、(-0.70±0.77)、(-0.74±1.09)mm。第1、2组间的差异无统计学意义(P>0.05);第2、3组间的差异有统计学意义(P<0.05),即术后第4周牙龈呈退缩趋势,平均退缩0.66 mm;第3、4组间的牙龈变化量也无明显差异(P>0.05),即牙龈愈合状态稳定。结论   牙周炎患者种植二期术后4周,种植体周围牙龈愈合达到稳定,可以进行取模修复;根据牙龈变化量可以指导种植基台的选择。

Abstract:

Objective   This study aimed to investigate the duration of gingival healing after the stage Ⅱ surgery of dental implantation for periodontitis patients and to provide clinical guidelines for implant restoration. Methods   Twenty-nine perio-dontitis patients who had implantation surgery and achieved osseointegration were operated with stage Ⅱ surgery (a total of 60 pieces of implants). The height of buccal gingival of each implant was measured twice after the stage Ⅱ surgery. All im-plants were measured at the lowest point of buccal gingival after one week. The implants were randomly divided into four groups according to the schedule of the next test time: group one at one week from the initial test point, group two at two weeks, group three at three weeks, and group four at four weeks. Each group includes 15 pieces of implants. The amount of the buccal gin-gival change in each group between the second and first tests was determined, and the data were analyzed statistically. Results   The amount of gingival change of groups one, two, three, and four was (-0.25±0.66), (-0.04±0.52), (-0.70±0.77), and (-0.74±1.09) mm, respectively. No significant difference was observed between groups one and two in terms of the amount of gingival changes (P>0.05). However, a significant difference was found between groups two and three (P<0.05), and the amount of gingival recession was 0.66?mm. No significant difference was found between groups three and four (P>0.05), and the gingival achieved stability. Conclusion   The gingival recession achieves stability at the fourth week (after 28 d) after stage Ⅱ surgery. At this time, the implant can be restored, and the abutment can be selected according to the amount of gingival change of the periodontitis patient.
