Nasoalveolar molding of the cleft lip, nose, and alveolar palate has been a successful strategy for the restoration of oronasal function and appearance, but it has some drawbacks. The temporary implant that is inserted before surgical reconstruction is a large appliance requiring numerous adjustments, it can irritate delicate soft tissues, and interfere with the infant’s ability to nurse or feed. In the early post-operative period and for months after cleft lip repair, patients wear standardized silicone stents that come in multiple sizes, but require significant sculpting to fit the unique cleft deformity. Three-dimensional (3D) printing offers the potential of highly personalized and patient-specific treatment. We developed a method that produces a customized 3D printed stent that matches the contours and unique features of each patient and permits modification and adjustments in size and shape as the patient ages. With 3D scanning technology, the device can be designed at the first visit to create an appliance that can be worn sequentially with minimal trauma, does not impede feeding, and a prosthesis that will improve compliance. The device will be worn intraorally to help shape the alveolus, lip, and nose before surgical repair. Furthermore, the stent can be doped with drugs as each patient’s case warrants. View Full-Text
