What this trial studies

This clinical trial investigates the effectiveness of two different bone graft materials used during guided bone regeneration procedures for patients requiring tooth extraction and subsequent implant placement. Participants will be divided into two groups: one receiving GTO® as the graft material and the other receiving Apatos Mix®. The study aims to compare the amount of bone regeneration and the histological outcomes between the two graft materials in cases where there is significant loss of the buccal ridge wall. All materials used are commercially available and approved for human use.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old in good health requiring single-tooth implants with significant buccal ridge loss.

Not a fit: Patients with systemic health issues or those under treatments that compromise wound healing may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve bone regeneration techniques, leading to better outcomes for patients receiving dental implants.

How similar studies have performed: Previous studies have shown promising results with similar bone grafting techniques, indicating potential for success in this approach.

  * Good general health.
  * Single-tooth implant treatment. Presence of adjacent teeth and opposing occluding teeth (for measurement stent indexing).
  * Incisors, canines and premolars.
  * Presence of three intact socket walls after tooth extraction with a defect of more than 50% loss of the buccal ridge wall and no fragment of root should be left.
