Impact of Hyaluronic Acid and Bone Graft on Peri-Implant Tissue
Impact of Hyaluronic Acid and Bone Graft on PeriImplant Tissue Phenotype."A Randomized Controlled Trial"
This randomized controlled clinical trial aims to evaluate the effect of hyaluronic acid (HA) and particulate bone graft on the peri-implant tissue phenotype in patients receiving dental implants. Healthy adult participants requiring dental implant placement will be randomly allocated into one of three equal groups (12 implants per group): Group 1 will receive dental implants combined with hyaluronic acid gel (Gengigel); Group 2 will receive dental implants combined with both hyaluronic acid and particulate bone graft; and the control group will receive dental implants alone.
Clinical and radiographic assessments will be performed using a customized measurement stent to ensure standardized evaluations at baseline, immediately postoperatively, and at 8 and 16 weeks of follow-up. The primary and secondary outcomes include alterations in ridge width, keratinized tissue width/thickness, radiographic soft tissue height, and marginal bone height. The study aims to determine whether the adjunctive use of hyaluronic acid and bone grafts enhances the quality of the peri-implant soft and hard tissue phenotype.

Postoperative Pain Scores
기간: Three times daily (morning, afternoon, and evening) for the first 7 days postoperatively
|
Patients received a standardized pain assessment chart for self-evaluation over seven consecutive postoperative days.
This chart featured an 11-point (0-10) Numerical Rating Scale (NRS) integrated with the Wong-Baker Faces Pain Rating Scale and supplemented with descriptive pain expressions ranging from a minimum value of 0 (representing no pain) to a maximum value of 10 (representing the worst possible pain), where higher scores indicate a worse outcome (greater pain severity).
