BACKGROUND/ PURPOSE: The connective tissue graft from hard palate is a reliable graft technique that has been used for achieving root coverage, increasing keratinized tissue width and thickness in periodontal plastic surgeries. Donor site morbidities, including complications from postoperative bleeding, pain during healing phase, difficulties in eating and speaking and unexpecting healing patterns, are always a concern for both doctors and patients. The aim of this study was to investigate a novel design of palatal stent to reduce these complications and provide patient with a smooth healing experience after soft tissue harvesting from hard palate.
Eight patients requiring connective tissue graft from palatal site were included in the study. The palatal stents made with light-curing hybrid composite resin were fabricated and tried in for patients prior to the periodontal plastic surgeries. Stent was delivered immediately without other dressing material or suture after the graft harvesting procedure for blood clot stabilization. Bleeding tendency was evaluated at the completion of the procedure. Patients came back for follow up in 1 week, 2 weeks and 1 month after the surgery. In the consecutive clinical cases, all patients reported minimal postoperative pain and discomfort (score ranged between 0 and 2). Both chewing and swallowing were not affected when wearing the stent, while four patients reported speaking inconvenience influenced by the stent.

背景/目的：硬腭结缔组织移植是一种可靠的移植技术，已用于牙周整形手术中实现牙根覆盖、增加角化组织宽度和厚度。供区并发症，包括术后出血、愈合期疼痛、进食和说话困难以及意外的愈合模式，一直是医生和患者关注的问题。本研究的目的是探讨一种新型腭部支架的设计，以减少这些并发症，并为患者在硬腭软组织采集后提供顺利的愈合体验。
本研究纳入了8例需要从腭部获取结缔组织移植的患者。在牙周整形手术前，制作了用光固化混合复合树脂制成的腭部支架，并为患者试戴。移植采集手术后，立即放置支架，不使用其他敷料材料或缝线以稳定血凝块。手术结束时评估出血倾向。患者在术后1周、2周和1个月回来进行随访。在连续的临床病例中，所有患者均报告术后疼痛和不适轻微（评分在0至2分之间）。佩戴支架时咀嚼和吞咽均未受影响，而4例患者报告说话受支架影响。
