Cleft lip and palate (CL/P) is the most prevalent craniofacial cleft type, appearing in 1 in 500-700 newborns. Alveolar bone graft surgery is just one of several surgeries CL/P patients undergo during infancy and childhood to correct the significant functional and esthetic deficits that result from clefting. Prior to this surgery, CL/P patients undergo rapid palatal expansion, which aligns the alveolar segments and provides sufficient space for the surgeon to place the bone graft. Conventional rapid palatal expanders (RPEs) are either tooth- or bone-borne and present obstacles to ideal treatment due to design constrictions. The goal of our proposed research is to design and fabricate a Smart Rapid Palatal Expander (S-RPE) that overcomes these obstacles. Our S-RPE has three key components: 1) The main mechanical frame that will apply stress to the palate by having a mechanical tensioning device, 2) A strain gage to measure the forces being applied by the tensioning device, 3) A microprocessor to read the strain gage measurement and store it in memory for wireless readout by an external device. The target of the S-RPE design is to significantly improve treatment outcomes of alveolar bone graft surgery and orthodontics in CL/P patients.
