A clinical controlled study on the recovery process of the palatal donor site after free gingival transplantation with personalized palatal guard plate intervention
个性化腭护板干预对游离龈移植术后腭侧供区恢复进程的临床对照研究

摘要

目的 探讨个性化腭护板在游离龈移植术后腭侧供区的应用评价。方法 选取2025年1月-2025年12月期间在我院种植科行游离龈移植术的90例牙列缺损患者，对照组（n=45）采用硬腭供区创面覆盖胶原蛋白海绵封闭创口，观察组（n=45）在此基础上，实施术前口扫取模制作的个性化腭护板于供区干预。护理团队指导佩戴与随访，系统化评估对比2组患者术后1、3天供区术后出血评分、疼痛视觉模拟评分（VAS）及涵盖进食、睡眠、语言、情绪等多维度的舒适度评分。结果 观察组患者术后1、3天出血评分、VAS评分均显著低于对照组（P<0.05）。在舒适度方面，观察组患者在进食受限、睡眠障碍、语言困难、负面情绪及社会活动影响等维度的评分均显著优于对照组，差异具有统计学意义（P<0.05）。这表明个性化腭护板有效提升了患者的游离龈移植术后生活质量。结论 个性化腭护板的制作与应用是一项关键且有效的供区干预措施。该举措能显著减轻患者游离龈移植术后痛苦，提升舒适度，体现了精准干预在治疗中的重要价值。

Abstract

Objective To explore the application evaluation of personalized palatal guard plates in the palatal donor area after free gingival transplantation.
Methods A total of 90 patients with dental arch defects who underwent free gingival transplantation in the implantology department of our hospital from January 2025 to December 2025 were selected. In the control group (n=45), the hard palate donor site wound was covered with collagen sponge to seal the wound. On this basis, the observation group (n=45) implemented personalized palate guard plates made by preoperative oral scanning and modeling for intervention in the donor site. The nursing team guided the wearing and follow-up, and systematically evaluated and compared the postoperative bleeding score, Visual Analogue Scale (VAS) for pain, and comfort score covering multiple dimensions such as eating, sleep, language, and emotion in the donor area of the two groups of patients on the 1st and 3rd days after surgery.
Results The bleeding score and VAS score of the observation group on the 1st and 3rd days after the operation were significantly lower than those of the control group (P<0.05). In terms of comfort, the scores of patients in the observation group in dimensions such as restricted eating, sleep disorders, language difficulties, negative emotions and the impact of social activities were significantly better than those in the control group, and the difference was statistically significant (P<0.05). This indicates that the personalized palatine guard plate effectively improves the quality of life of patients after free gingival transplantation.
Conclusion   The production and application of personalized palatal guard plates is a key and effective donor site intervention measure. This measure can significantly alleviate the postoperative pain of patients after free gingival transplantation and enhance their comfort level, demonstrating the significant value of precise intervention in treatment.
