Evaluation of the Effect of Different Biomaterials on Palatal Wound Healing.

Evaluation of the Effect of Different Biomaterials on Palatal Wound Healing. A Randomized Controlled Clinical Study

All study subjects will sign written informal consent form before enrolment.

They will be divided into four groups, 10 patients each:

• Group I: Palatal wound will be left to heal spontaneously,
• Group II: Palatal wound will be covered with Composite stent,
• Group III: Palatal wound will be covered with PRF,
• Group IV: Palatal wound will be covered with Ora-aid patch. III- Surgical Procedures: -
• After harvesting the palatal soft tissue graft with the standardized dimensions (12 × 7 mm) of the graft for all patients. Graft thickness was standardized as well to be approximately 1.5 to 2 mm and confirmed with a caliper at 3 points (ends and centre of the graft). Fixing of the graft at the recipient site will be performed, back to the donor site for management, the blood clot will be wiped with gauze, then placement of different materials according to each group.
• The dressing will be then pressed gently for 10 seconds, to aid its adherence to the wound. Fixation of the patch will be followed, using 5/0 propylene suture, with performing sling horizontal figure eight suture technique.

Inclusion Criteria:-

• Medically free patients,
• Non-smokers and
• Patients with good oral hygiene. Exclusion Criteria:-
• Pregnant or lactating females,
• Patients with untreated periodontal condition and
• Patients with uncontrolled systemic condition.
