A novel design of palatal stent to reduce donor site morbidity in periodontal plastic surgery
Abstract
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. Materials and methods: 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. Results: In the consecutive clinical cases, all patient 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 influenced by the stent. Conclusion: The novel design of palatal stent reduces donor site morbidity and provides patient with a good healing experience after soft tissue harvesting from hard palate.
