Two Types of PRF Membranes in Management of Dehiscence Defect in Posterior Mandible

Comparing Two Types of PRF Membranes in Management of Dehiscence Defect With Simultaneous Implant Placement in Posterior Mandible (Randomized Controlled Clinical Trial)

Background: Placement of implants in an atrophic posterior ridge is a challenge for so many clinicians. The success of dental implants depends on the volume of alveolar bone available to provide stability. Bone grafting using xenograft with PRF and e-PRF as a membrane has shown promising results in both bone healing and defect reconstruction. Aim of the study: to evaluate the effect of Platelet-rich fibrin (PRF) and Extended Platelet-rich fibrin (e-PRF) as a membrane with xenograft to increase the width of ridge in posterior mandible with simultaneous implant placement.

Inclusion Criteria:

• Patient with one or more missing posterior mandibular teeth.
• Patient with atrophic posterior mandible with residual ridge width in the range of 4 to 6mm.
• Patient with good oral hygiene and acceptable inter-arch space less than or equal to the restoration

Exclusion Criteria:

• The patient underwent alveolar ridge reconstruction in the same area.
• Patients with immune diseases, uncontrolled hypertension, and uncontrolled diabetes.
• Patient with any pathological condition at the site of surgery.
• Heavy smoker, alcohol abuse, parafunctional habits.
