Diagnostic Protocols for Alveolar Clefting and Barriers to Acquiring Imaging: A Survey of ACPA-Approved Cleft Teams in the United States.

Objective: To report current diagnostic protocols, practices, and barriers related to imaging of alveolar clefting among American Cleft Palate-Craniofacial Association (ACPA)-approved cleft/craniofacial teams.

Methods: An electronic survey was sent to 162 ACPA-approved teams in the United States. Key items were team location, venue of orthodontic treatment, imaging modality(s) and access, barriers to imaging, billing, imaging protocols including team members involved in decisions pre- and post-alveolar bone grafting (ABG), and craniofacial fellowship status of team orthodontist(s).

Results: A total of 66 responses were received (40.7%). Responding teams were university-based (47%), hospital-based (42.4%), and independent clinics (10.6%). Orthodontic treatment for most patients was in private practice (53%). On-site 2-dimensional (2D) and 3-dimensional (3D) dental imaging capabilities were reported by 42% of teams; 29% have no on-site imaging. One or more barrier(s) to acquiring imaging were reported by 67%, with insurance challenges reported by 47%. Most teams bill medical payors for cleft-related dental imaging (58%). Pre- and post-ABG imaging was most frequently 3D (35% and 36%, respectively). Surgeons and orthodontists commonly evaluate ABG timing and outcome together (53%-65%). Periapical radiographs were included significantly more often in cleft imaging protocols by orthodontists with versus without fellowship training ( = .011,  = .04).

Conclusions: Barriers to acquiring imaging are frequent. 3D is the most common imaging pre- and post-ABG. Our study endorses multi-level advocacy for improved medical insurance coverage of diagnostic cleft-related dental imaging to decrease barriers to providing timely care.
