Clinical Trial Summary

The goal of this study is to evaluate the capacity of allogeneic bone marrow mesenchymal stromal cells (MSC) to induce bone regeneration in patients with periodontal disease. MSC cultured are loaded on a collagen scaffold, included into autologous platelet rich plasma clot and implanted in the bone defect.

Description:

The clinical protocol is designed to evaluate the bone regeneration capacity of allogeneic MSCs for the treatment of patients with chronic or aggressive periodontal disease. Patients with either a 2- or 3-wall intrabony defects are included in this study. A bioengineering construct, constituted by allogeneic MSCs and a collagen scaffold, is incorporated into platelet rich plasma (PRP) clot, which is implanted at the bone defect site. Follow up of treated tooth are assessed by clinical evaluation, intraoral radiography and cone-beam CT.

Intervention

Biological:
• Transplantation of allogeneic MSCs in periodontal disease
Oral surgery is performed in patients with periodontal disease, under local anesthesia. An incision will be made on the periodontal lesion, A full-thickness flap is elevated on both the buccal and lingual areas and the inner epithelium of the flap removed. Granulation tissue is removed from bone defect area, and a root planning is performed. MSC construct is placed around the bone defect and a collagen membrane is used to cover and close off the bone defect site. The flap will be repositioned and the wound closed by a suture

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in clinical attachment level (CAL)	Expressed as the distance in millimeters from the cemento-enamel junction (CEJ) to the bottom of the probable gingival/periodontal pocket.	Follow-up includes evaluation at 3, 6, 9 and 12 months post-transplantation
Primary	Change in probing pocket depth (PPD)	The distance from the gingival margin to the bottom of the gingival sulcus/pocket, is measured by means of periodontal probe.	Follow-up includes evaluation at 3, 6, 9 and 12 months post-transplantation
Primary	Gingival recession (GR)	Exposure of the tooth through apical migration of the gingiva will be recorded as the distance in millimeters from the CEJ to the gingival margin	Follow-up includes evaluation at 3, 6, 9 and 12 months post-transplantation
Primary	Change in bone density	Changes in the density of the periodontal bone defect will be detected by Cone beam Tomography	Follow-up includes evaluation at 3, 6, 9 and 12 months post-transplantation
Primary	Change in Tooth Mobility (TM)	Changes from baseline in tooth mobility will be recorded.	Follow-up includes evaluation at 3, 6, 9 and 12 months post-transplantation
Primary	Change in bone depth	The vertical bone defects will be assessed by X-rays. The postoperative depth of the intrabony defect will be calculated from the distance between the cemento-enamel junction and the bone crest on the preoperative and postoperative radiographs at the same magnification.	Follow-up includes evaluation at 3, 6, 9 and 12 months post-transplantation
