Application of Alloplastic Bone Graft With Polycaprolactone (PCL) Membrane and ECM-Collagen Membrane on Secondary Socket Healing in Third Molar Surgery. (PCL ECM)

16. September 2026 aktualisiert von: Tan Chuey Chuan, University of Malaya

A Comparative Study on the Application of Alloplastic Bone Graft With Polycaprolactone (PCL) Membrane and ECM-Collagen Membrane on Secondary Socket Healing in Third Molar Surgery.

This study compared two membrane materials: 1. polycaprolactone (PCL) and 2. Extracellular matrix collagen membrane (ECM) as alternative. This is to see how well they prevent bone and gum damage after lower wisdom tooth removal. In this split-mouth trial, participants had both lower wisdom teeth removed, with one socket receiving PCL membrane and the other receiving ECM membrane after socket filled with EthOss (an alloplastic bone graft). Over a 24-week follow-up period, researchers tracked patient clinically on their comfort, gum healing, and new bone growth using X-rays.

Detaillierte Beschreibung

Surgical removal of impacted mandibular third molars (M3) often associated with post-operative morbidities such as pain, facial swelling, limited mouth opening and injuries to the inferior alveolar nerve or lingual nerve. In addition, it can result in compromised periodontal health of the adjacent second molar (M2) and reduced alveolar bone height at the M3 region. The defect can be restored using bone substitutes with membrane. This study aims to assess wound healing of the surgical sites of third molar surgery with application of alloplastic bone graft with PCL membrane and ECM-collagen membrane. This is a split-mouth, double blinded, randomized controlled study. Participants underwent surgical removal of bilateral impacted mandibular third molars with either socket covered with PCL membrane and ECM-collagen membrane after filled up EthOss® alloplastic graft. The participants will be reviewed at post-operative 1 week (T1), 1 month (T2), 3 months (T3) and 6 months (T4) to monitor for signs of graft reaction/rejection. Periodontal assessments were performed at these four visits to assess the soft tissue healing. Radiological assessment (intraoral periapical x-ray) will be done at preoperative and post-operative week 24 to assess bone depth.

Teilnehmergruppe / Arm
Intervention / Behandlung
Aktiver Komparator: PCL membrane

This is a split-mouth, randomized, within-subject clinical trial using a crossover assignment model. Each participant serves as their own control, receiving both Intervention 1. PCL membrane and Intervention 2. ECM collagen membrane after socket filled with Ethoss alloplast material simultaneously on either sides of the lower third molar

This is a split-mouth, randomized, within-subject clinical trial using a crossover assignment model. Each participant serves as their own control, receiving both Intervention 1. PCL membrane and Intervention 2.ECM collagen membrane simultaneously on opposite sides of the lower third molar after socket filled up with alloplast.
