Combined Bilaminar Tunnel Technique in Treating Difficult Gingival Recessions
Taiwan12 participantsStarted 2022-04-27
Plain-language summary
The goal of this clinical trial is to learn if the combined bilaminar tunnel technique works to treat anatomically difficult gingival recessions. It will also explore whether anatomical factors are associated with root coverage outcomes. The main questions it aims to answer are:
Does the combined bilaminar tunnel technique improve root coverage outcomes in patients with anatomically difficult gingival recessions? Are specific anatomical factors associated with root coverage outcomes after the combined bilaminar tunnel technique?
Participants will:
Receive root coverage surgery using the combined bilaminar tunnel technique Visit the clinic for follow-up evaluations after surgery Receive clinical measurements to assess gingival recession and root coverage outcomes Receive radiographic evaluation to assess anatomical characteristics, if clinically indicated or available

Inclusion Criteria:
* Orthodontic patients who were going to be treated with cTUN approach for soft tissue modification.
* Healthy periodontal condition or well controlled periodontitis with periodontal probing depth ≦ 3mm, and absence of bleeding on probing.
* Thin gingival phenotype, determined with visible metal shade\[27\]
* Intact clinical and pre-surgery radiographic data (CBCT) was available, and the patient followed the recommended supportive post-surgery treatment at least 6 month after the surgery.
* Informed consent had been obtained prior to the mucogingival surgery.
Exclusion Criteria:
* Uncontrolled systemic disease, such as hypertension, diabetes.
* Untreated periodontitis
* History of radiation therapy on head and neck regions.
* Heavy smokers (more than 0.5 pack per day).
* Patient with pregnancy or breastfeeding.

* Patient who did not comply to the recommended supportive treatment was regarded as erratic complier.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
