FROM ARCH TO DOME: MAXILLARY EXPANSION FOR SLEEP

Friday, 21 May 2021 (PM)
Galleria I, Level 3, Grand Copthorne Waterfront Hotel, Singapore

  • PROGRAMME

Maxillary expansion has attracted attention for the treatment of nasal breathing, particularly in children and adults with sleep-disordered breathing, ranging from UARS to OSA. 

While clinical indications for maxillary expansion in dentofacial deformity and malocclusion are well-understood, modifications to establish favorable nasal breathing and tongue position during sleep are evolving. 

Since the advent of DOME (distraction osteogenesis for maxillary expansion) from Stanford, we have successfully designed a protocol for expansion with efficiency and efficacy in adults ranging from 15 to 58 years old. From surgical techniques to mechanism of action to large series outcomes, we have published in both otolaryngology and sleep medicine journals. (See References 1-6) 

We are now ready to share with all surgeons and dentists the nuances of maxillary expansion, from the pediatric to the adult patient, to address the unfavorable phenotype of high-arched, narrow hard palate. 

​This is a hands-on course. Real cases with their associated 3-D printed models (jaw and skull) will be provided to all attendees. The idea is to return home and start providing a much needed service to patients with this phenotype. Small teams of dental and surgical attendees will be assigned together, where the collaborative nature of maxillary expansion will be demonstrated.

​At the conclusion of the workshop, attendees will understand
  • Why the nasomaxillary Complex is a target for OSA treatment
  • What are the short and long-term implications of maxillary expansion
  • How to design a maxillary expander for all ages
  • When to perform minimally invasive osteotomy for DOME
