【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(P0.05);第2、3组间的差异有统计学意义(P0.05),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(P0.05),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 to explore the time for the healing of gingival healing after two stages of periodontitis, and to provide guidance for the implantation and repair of patients with periodontitis. Methods 29 cases of periodontitis who had been implanted (60) had been implanted with the bone combination were planted for two stages, and the height of the buccal gingiva of each implant was measured 2 times after operation. The gingival cheek of all implants was measured at the lowest point in 1 weeks and set as the initial test point. Then according to the observation time, it was divided into group 1,2,3,4, each group had 15 implants, and second measurements were carried out at the first 2,3,4,5 week after the operation. The gingival changes in the 4 groups were measured with the initial test points and were statistically analyzed. Results the gingival changes in the 4 groups were measured. The difference between (-0.25 + 0.66), (-0.04 + 0.52), (-0.70 + 0.77), (-0.74 + 1.09) mm., 1,2 group was not statistically significant (P0.05); the difference between group 2,3 was statistically significant (P0.05), that is, the gingiva showed a shrinking trend in fourth weeks after operation, the average contraction of 0.66 mm, and there was no significant difference between the gingival changes between the group of 3,4 (P0.05), that is, the healing state of the gums was stable. Conclusion the gingival healing around the implant is stable at 4 weeks after the two stage of implantation of periodontitis, and the gingival changes can be used to guide the selection of the implant base.
