Marginal Bone Height Changes Around Two Different Surface Treated Dental Implants Supporting Mandibular Complete Overdenture.

Marginal Bone Height Changes Around Two Different Surface Treated Dental Implants Supporting Mandibular Complete Overdenture.

Patients participating in this study were rehabilitated by mucosa supported maxillary complete denture and mandibular overdenture supported by two different surface treated implants; resorbable blast media (RBM) on the right and Acid etched on the left; retained by ball attachments. The marginal bone height changes around RBM and acid etched surface treated dental implants retaining mandibular complete overdenture were assessed by cone beam computed tomography.

Inclusion Criteria:

• Free from any systemic diseases affecting the bone metabolism.
• Healthy, firm covering mucosa which is free from any signs of Inflammation or ulceration.
• Residual alveolar ridge with adequate height and width.
• Angel's class I classification maxillo - mandibular relationship.
• Sufficient inter arch space

Exclusion Criteria:

• Smoker.
• Patients with parafunction habits (clenching or bruxism).
