Comparing guided and spontaneous bone regeneration for maxillary cyst removal

Radiographic and Histological Assessment of Guided Bone Regeneration Using Deproteinized Bovine Bone Compared to Spontaneous Bone Regeneration of Maxillary Defects , Resulted from Enucleation of Intra-bony Cystic Lesions : Randomized Control Clinical Trial

Not applicable Interventional Cairo University · NCT06749158

This study is testing whether a special bone treatment helps people heal better after having cysts removed from their upper jaw compared to letting their body heal on its own.

What this trial studies

This clinical trial involves two groups of patients with maxillary defects caused by the removal of intra-bony cystic lesions. One group will undergo guided bone regeneration (GBR) using deproteinized bovine bone, while the other will rely on spontaneous bone regeneration. Pre-operative preparations include periodontal therapy and endodontic treatment, followed by a standardized surgical procedure to enucleate the lesions. The study aims to assess the effectiveness of GBR compared to natural healing processes in these patients.

Who should consider this trial

Good fit: Ideal candidates are patients aged 20-50 with maxillary intra-bony defects suitable for implant placement.

Not a fit: Patients with systemic conditions affecting bone healing or those with active infections at the surgical site may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve surgical outcomes and healing processes for patients with maxillary cysts.

How similar studies have performed: Previous studies have shown promising results for guided bone regeneration techniques, suggesting potential success for this approach.
