Impact of Hyaluronic Acid and Bone Graft on Peri-Implant Tissue

28. juni 2026 opdateret af: Monya Noori Hassan, Al-Mustansiriyah University

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.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Group 1: Dental Implants + Hyaluronic Acid
Patients receive dental implants combined with hyaluronic acid gel applied at the implant site.
Procedure: Dental Implants with Hyaluronic Acid
Surgical placement of dental implants, followed by the application of hyaluronic acid gel at the implant site, was performed to evaluate its impact on peri-implant tissue phenotype.
Eksperimentel: Group 2: Dental Implants + Hyaluronic Acid + Bone Graft
Patients receive dental implants combined with hyaluronic acid gel and particulate bone graft applied at the implant site.
Procedure: Dental Implants with Hyaluronic Acid and Particulate Bone Graft
Surgical placement of dental implants, combined with the application of hyaluronic acid gel and particulate bone graft at the implant site, was performed to evaluate its impact on peri-implant tissue phenotype.
Aktiv komparator: Group 3: Control Group: Dental Implants Alone
Patients receive standard dental implants placement alone without any adjunctive materials.
Procedure: Standard Dental Implants Placement only
Standard surgical placement of dental implants following conventional clinical protocols without the application of any adjunctive materials.

Tidsramme
Ridge Width Changes (RW)
Tidsramme: Baseline (preoperative), immediate postoperative, 8 weeks, and 16 weeks.
The changes in Ridge Width is measured at the reference points using a digital vernier caliper.
Baseline (preoperative), immediate postoperative, 8 weeks, and 16 weeks.
Bone Width (BW)
Tidsramme: Baseline (preoperative), and 16 weeks postoperatively
Measured in millimeters by subtracting the buccal and lingual mucosal thickness from the ridge width.
Baseline (preoperative), and 16 weeks postoperatively
Change in width of keratinized tissue (KTW)
Tidsramme: Baseline (preoperative), 8 weeks, and 16 weeks
Measured in millimeters at the mid-buccal aspect of the implant site using an endodontic rotary file and digital vernier caliper.
Baseline (preoperative), 8 weeks, and 16 weeks
Keratinized Tissue Thickness (KTT)
Tidsramme: Baseline (preoperative), and 16 weeks postoperatively
Measured in millimeters at the buccal, crestal and lingual reference points using a periodontal probe and a digital vernier caliper.
Baseline (preoperative), and 16 weeks postoperatively
Radiographic Mucosal Thickness (RT)
Tidsramme: Baseline (preoperative), immediate postoperative, 8 weeks, and 16 weeks
Measured in millimeters on periapical radiographs using digital software from the crestal bone level to the crest of crestal oral mucosa 5 mm away from the height distal surface of the adjacent tooth on the mesial side of the implant.
Baseline (preoperative), immediate postoperative, 8 weeks, and 16 weeks
Crestal Bone Height (BH)
Tidsramme: Immediate postoperative, 8 weeks, and 16 weeks

Postoperative Pain Scores
Tidsramme: 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).
Three times daily (morning, afternoon, and evening) for the first 7 days postoperatively
