Efficacy in Alveolar Bone Regeneration With Autologous MSCs and Biomaterial in Comparison to Autologous Bone Grafting

A phase III multi center clinical trial, randomized and controlled.The study subject is lacking one or more sheet behind the canine in the upper or lower jaw, and the alveolar ridge is too narrow to place a dental implant. The test objects will have augmentation using autologous mesenchymal stromal cells and a biomaterial, biphasic Calcium Phosphate. The control is the traditional bone block from the ramus.

Inclusion criteria

• Healthy, non smoking patients in need of dental implants in the upper or lower jaw, with loss in vertical height and less that 4 mm in lateral width.

Exclusion criteria

• General contraindications for dental and/or surgical treatments
• Contraindications for both bone marrow harvesting and bone grafts
• History of any malignant diseases
• Concurrent or previous radiotherapy of head and neck region
• History of contagious diseases (HIV, HTLV and/or syphilis seropositivity, hepatitis B or C infection)
• Uncontrolled diabetes mellitis, e.g. patients with diabetes not regulated with medications or diet. This will be verified based on patient's history and concurrent HbA1c levels (HbA1c > 53 mmol/mol).
• Inflammatory and autoimmune disease of the oral cavity.
• Concurrent or previous immunosuppressant, bisphosphonate or high dose corticosteroid therapy.
