NCT06900036

Brief Summary

This randomized controlled trial is designed to assess the use of platelet-rich fibrin (PRF), a biomaterial derived from a participant's own blood, in alveolar ridge preservation following premolar extraction for orthodontic purposes. Participants aged 17 to 38 years requiring premolar extractions will be randomly assigned to receive either PRF application or natural healing without intervention. Cone beam computed tomography (CBCT) will be used to evaluate changes in alveolar bone dimensions and density at 30 and 120 days post-extraction. Measurements will be taken at standardized vertical levels (1 mm, 3 mm, and 5 mm apical to the crest) to analyze bone height, width, and density over time.

Outcome Measures

Primary Outcomes (1)

  • Change in alveolar bone height (mm) at 30 and 120 days post-extraction as measured by CBCT

    Alveolar bone height will be measured from the most apical point of the socket to the crestal margin using CBCT (cone beam computed tomography) scans at baseline (day of extraction), 30 days, and 120 days post-extraction. Measurements will be recorded in millimeters and compared between PRF-treated sites and control sites (no PRF). The mean difference in height over time will be calculated within and between groups.

    Baseline (immediately post-extraction), 30 days, and 120 days post-extraction.

Secondary Outcomes (2)

  • Change in alveolar bone depth (mm) at 1 mm, 3 mm, and 5 mm from crest, at 30 and 120 days post-extraction

    Baseline, 30 days, and 120 days post-extraction.

  • Bone tissue density (HU) at 30 and 120 days post-extraction measured via CBCT

    Baseline, 30 days, and 120 days post-extraction.

Study Arms (2)

Platelet-Rich Fibrin (PRF) Application for Alveolar Preservation

EXPERIMENTAL

This arm involves the application of Platelet-Rich Fibrin (PRF) immediately after premolar extraction to evaluate its effectiveness in preserving alveolar bone structure and enhancing bone regeneration. PRF is a natural, autologous biomaterial obtained from the patient's own blood, promoting wound healing, bone preservation, and tissue regeneration.

Procedure: Platelet-Rich Fibrin (PRF) Application for Alveolar Preservation

Control Group - Natural Healing (No PRF Application)

NO INTERVENTION

This arm represents the control group, where participants undergo standard premolar extraction without the application of platelet-rich fibrin (PRF). This allows for a direct comparison to assess the effectiveness of PRF in preserving alveolar bone and enhancing healing.

Interventions

This intervention involves the application of platelet-rich fibrin (PRF) in the extraction socket following premolar extraction to assess its effectiveness in alveolar bone preservation. PRF is a biological autologous material derived from the patient's own blood, promoting bone regeneration, wound healing, and tissue repair.

Eligibility Criteria

Age17 Years+
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Healthy individuals with no systemic diseases.
  • Age range: 17 to 38 years old.
  • Orthodontic indication for premolar extraction (two maxillary or two mandibular premolars).
  • Candidates for orthognathic surgery or extraction of impacted/retained teeth (e.g., third molars with a relationship to critical anatomical structures).
  • Clinical justification for CBCT imaging instead of standard radiographic -techniques.

You may not qualify if:

  • Patients with systemic diseases that may alter periodontal therapy outcomes.
  • Platelet count below 200,000 mm³.
  • Immunosuppressed patients.
  • Pregnant or lactating women.
  • Smokers.
  • Patients taking medications that interfere with healing (e.g., bisphosphonates, corticosteroids, anticoagulants).
