  • Amount of New Bone Mass Formed [ Time Frame: 6 months from surgical procedure for alveolar grafting; ] [ Designated as safety issue: Yes ]
    The quantification of bone formation will be conducted by analysis of CT scans of alveolar cleft area that receive autogenous mesenchymal stem cells from dental pulp associated with the biomaterial 3 and 6 months after surgical procedure ( tissue engineering ) in comparison with CT Scan previously of tissue engineering surgery.Preoperative and follow-up examinations reveled progressive alveolar bone union in all patients. For these 5 patients final completion of the alveolar defect with an 89,5% mean bone height was detected 6 months postoperatively. We are still waiting the canine dental eruption at the new bone. For these group of patients the bone tissue engineering using autologous mesenchymal stem cells associated with biomaterial resulted in satisfactory bone healing.
  • Quality of Bone Regeneration [ Time Frame: Three months after the graft ] [ Designated as safety issue: Yes ]
    The quality of bone formation will be conducted by analysis of CT scans of alveolar cleft area through canine tooth eruption in these position of new bone formation by tissue engineering techniques. We are waiting the canine eruption at the mouth.
  • Amount of new bone mass formed [ Time Frame: 3 months from surgical procedure for alveolar grafting; ] [ Designated as safety issue: Yes ]
    The quantification of bone formation will be conducted by analysis of CT scans of alveolar cleft area that receive autogenous mesenchymal stem cells from dental pulp associated with the biomaterial 3 months from surgical procedure of tissue engineering.

Use of Mesenchymal Stem Cells for Alveolar Bone Tissue Engineering for Cleft Lip and Palate Patients
Use of Mesenchymal Stem Cells for Alveolar Bone Tissue Engineering for Cleft Lip and Palate Patients

The aim of this study is to perform the bone tissue engineering to reconstruct the alveolar bone defect in cleft lip and palate patients using mesenchymal stem cells from deciduous dental pulp associated with a collagen and hydroxyapatite biomaterial (Geistlich Bio-Oss®) through prospective qualitative and quantitative analysis of bone neoformation.

The reconstruction of the craniofacial skeleton in development between 2 and 10 years old, remains a major challenge for reconstructive plastic surgery. Local autogenous bone is practically unavailable, the distant bone graft has significant morbidity and use of alloplastic materials is incompatible with the growing facial skeleton. With the advent of bioengineered tissue, however, osteogenesis induced by the use of mesenchymal stem cells associated with biomaterials has become a potential solution to the shortage bone-related morbidity and donor bone in the region in pediatric patients.

The association of mesenchymal stem cells to biomaterials has provided new bone formation and a significant reduction of morbidity, for rehabilitation of the alveolar bone in patients with cleft lip palate.

To perform the rehabilitation of alveolar bone cleft, other donor regions of bone (iliac crest, ribs, skull) suffer morbidity for obtaining bone to be used in alveolar bone grafting. In order to eliminate the morbidity at the bone donor region for these patients and reduce costs of patient permanence in the operating room the aim of this study is to perform the bone tissue engineering to reconstruct the alveolar bone defect in cleft lip and palate patients using mesenchymal stem cells from deciduous dental pulp associated with a collagen and hydroxyapatite biomaterial (Geistlich Bio-Oss®) through prospective qualitative and quantitative analysis of bone neoformation.
