The purpose of this trial is to evaluate if the use of Bone Morphogenic Protein(BMP)/Demineralized Bone Matrix (DBM) versus the use of autologous Iliac Crest Bone Graft (ICBG) will result in an increase in total cost effectiveness for patients undergoing alveolar bone graft (ABG) for Cleft Lip and Palate (CLP) and to see if patients who are treated with DBM/BMP will have reduced post-operative pain scores,reduced operative times,and similar rates of bone healing compared to conventional ICBG.

| Intervention group (DBM/BMP) | Drug | All patients will undergo a standard procedure for exposure of the cleft alveolar defect and closure of all oronasal fistulae. After induction of general anesthesia, the patient will be intubated with an oral ray tube and prepped and draped in sterile fashion. Pre-operative antibiotics will be given to cover oral flora (i.e. Unasyn or clindamycin if penicillin allergy exists). The intra-oral space will be exposed and the nasal floor and palatal mucosa will be primarily closed to create a water-tight space for the graft. The integrity of the nasal floor mucosa will be tested using methylene blue dye. Following closure of the fistula, the alveolar bone graft will be performed. For the treatment group, 10cc of crushed DBM will be mixed with the micro-sized sponge of rh-BMP-2 (Infuse Bone Graft, Medronic, Minneapolis, MN). The sponge and DBM will then be packed into the defect to completely fill the bony space (FIGURE 3). The anterior mucosa will then be closed. |

| Health system costs per successful bone graft. | Health system costs will be reported as the total sum of all costs including incremental surgeon time costs, hospital costs, revision costs, and additional outpatient costs for clinic or ER visits. Bone graft success be defined as no need for a repeat bone graft, as well as by assessment by blinded orthodontist evaluations of the Post op Cone beam computed tomography(CBCT). | One year post graft |
| Measure | Description | Time Frame |
|---|---|---|
| Graft Success | Graft success as indicated by number of patients that did not have exposure of graft as assessed by post op CBCT | 3 months post graft |
| Infection | Graft success as indicated by number of patients that had no graft infection as assessed by post op CBCT |

To prevent surgeon bias in operative time and therefore cost, randomization assignments will be concealed at the beginning of surgery. The surgeon will start with closure of the oronasal fistula first. Once that is completed, the envelope will be opened and reveal the type of bone graft selected. The surgeon will then either harvest the additional ICBG or open the packets for the DBM/BMP and pack the selected type of bone into the alveolus.
Outcomes assessor including orthodontist and clinical research evaluator will be blinded to treatment arms.

| Control group(autologous ICBG) | Drug | The patient will be induced with anesthesia, prepped, and draped. The intra-oral space will be exposed and the nasal floor and palatal mucosa will be primarily closed to create a water-tight space for the graft. The integrity of the nasal floor mucosa will be tested using methylene blue dye. Following closure of the fistula, the alveolar bone graft will be performed.In the control group, the ICBG will be harvested percutaneously using the Accumed bone graft harvesting system. Briefly, an incision will be made in iliac crest and drill bit inserted. Multiple passes of the drill be used to harvest as much autograft bone as possible from the cancellous region of the iliac crest.Following harvest, fibrin glue will be instilled for hemostasis and a Ropivicaine On-Q pain pump inserted for post-operative pain control. The harvest bone graft will be packed into the alveolar defect in a similar fashion and the mucosa closed anteriorly. |
