429 - Use of a 3D-Printed Laryngeal Mask Airway Mouth Prop During Pediatric Dental Sedation Procedures

Purpose: We have started using a flexible Laryngeal Mask Airway (LMA) to facilitate pediatric deep sedation in the office. So far we have completed ~30 patients, aged 6-8 years with a median of 8 dental procedures per patient. The aim of this prospective study is to determine effectiveness of using a 3D-Printed (LMA) Mouth Prop during Deep Sedation procedures in a dental office setting. We have previously reported the successful use of a mouth prop/ LMA in oral surgery.

Methods: We plan to recruit twenty children aged 6 to 10, ASA 1-2, who are referred to LMA (suitable for size 2.5 LMA) Deep Sedation for restorative dental work. Dental providers will complete previously planned restorative work in all cases with the 3D-Printed LMA Mouth Prop in place. This new Prop was designed on a CAD program and printed using a Sprintray 3D printer. The first 10 children will receive maintenance with sevoflurane and the second 10 will receive maintenance with propofol. 

Results: After recruitment has started data will be collected using scoring tables completed by the anesthesiologist and dental provider. Anesthesiologist scoring tables detail ease of LMA placement, management of anesthesia, airway issues and post-operative recovery. Dental provider scoring tables include ease of access of each dental procedure completed. 

Conclusion: It is anticipated that at the end of the study, a 3D-Printed LMA Mouth Prop will provide appropriate deep sedation/anesthesia, and appropriate access for dental providers to complete in-office pediatric dental sedation.
