摘要:

目的：探究游离龈移植术对重建下颌后牙种植区角化龈的宽度、厚度以及骨吸收量的影响。方法：选取2018年3月-2020年3月笔者医院收治的重建下颌后牙患者106例。采用随机数字法将所有患者分为观察组（n=53）和对照组（n=53），观察组患者实施游离龈移植术，对照组患者实施根向复位瓣术。术后2个月、5个月，分别对两组患者的角化龈宽度进行比较；术后5个月，对两组患者的角化龈厚度及两组患者骨吸收量进行比较。术后5个月，分别对两组患者的组织瓣宽度和表面积进行比较。对术后1周内两组出现的出血、水肿以及疼痛进行评分并比较。结果：与对照组比较，观察组术后2、14个月的角化龈宽度显著上升（P＜0.05）；观察组术后5个月的角化龈厚度显著提高（P＜0.05），观察组的骨吸收量显著低于对照组，差异有统计学意义（P＜0.05）。与对照组比较，观察组术后5个月的组织瓣水平向和垂直向宽度以及组织瓣表面积均显著上升，差异有统计学意义（P＜0.05）。术后1周内，两组患者的出血、水肿以及疼痛评分比较差异均无统计学意义（P＞0.05）。结论：游离龈移植术能够显著提高重建下颌后牙种植区角化龈的宽度和厚度，且能够降低骨吸收量，术后出血量较少，值得临床推广应用。

Abstract:

Objective To investigate the effects of free gingival transplantation on the width, thickness and bone absorption of keratinized gingival in reconstructed mandibular posterior tooth planting area. Methods 106 patients with reconstructed mandibular posterior teeth admitted to our hospital from March 2018 to March 2020 were selected. All patients were divided into observation group (n=53) and control group (n=53) by random number method. Free gingival transplantation was performed in observation group, and radical reduction flap was performed in control group. The width of keratogingival was compared 2 months and 5 months after operation. The thickness of keratogingival was compared between the two groups 5 months after operation. The bone absorption of fever was compared between the two groups. The tissue flap width and surface area of the two groups were compared 5 months after surgery. Bleeding, edema, and pain were scored and compared between the two groups within one week after surgery. Results Compared with the control group, the width of keratinized gingival in the observation group increased significantly at 2 and 14 months after operation (P ＜0.05). The thickness of keratinized gingival in the observation group was significantly increased 5 months after operation (P＜0.05). Bone resorption in the observation group was significantly higher than that in the control group (P＜0.05). Compared with the control group, the horizontal and vertical width and surface area of the tissue flap in the observation group were significantly increased 5 months after the operation (P＜0.05). There was no significant difference in bleeding, edema, or pain scores between the two groups within one week after surgery (P ＞0.05). Conclusion Free gingival transplantation can significantly improve the width and thickness of keratinized gingival in reconstructed mandibular posterior tooth planting area, reduce bone absorption, and reduce postoperative blood loss, which is worthy of further clinical application.
