OBJECTIVE: This study aimed to propose digitally designed impression trays, for newborns with cleft lip and palate (CLP) defects, using the computer-assisted design and manufacturing (CAD/CAM) technique, based on measurements of width, length, and height made on processed and scanned plaster models. Thus, we will describe the different software and concepts that can be used for the design of these impression trays.
DESIGN: A total of 59 plaster casts of newborn patients with CLP were collected and then scanned. After that, digital dental casts were three-dimensional (3D) evaluated, using precise anatomical landmarks.
SETTING: The Maxillofacial Prosthodontics Team at the Dental consultation and treatment center in Rabat, Morocco.
PATIENTS AND PARTICIPANTS: The study involved plaster casts of newborns with CLP, who had undergone presurgical neonatal treatment in the Maxillofacial Prosthodontics service in Rabat, Morocco.
INTERVENTIONS: None.
MAIN OUTCOME MEASURE(S): 3D evaluation of 59 scanned plaster casts of newborn patients with CLP.
RESULTS: This work allowed us to obtain digital impression trays for each anatomical variation of orofacial clefts. These trays will limit the problems linked to conventional techniques for making neonatal orthopedic plates. We also emphasized the importance of a multidisciplinary approach involving several professionals in Morocco from various fields and specialties.
CONCLUSION: This original technique is advantageous for the practitioner as well as for the patients and their parents. It allows for precise recording, better adaptation, time-saving, and parental comfort.
