Dr. Ron Barzilay, D.ABDSM works in close partnership with sleep physicians, respirologists, and family physicians across Hamilton and the Golden Horseshoe to co-manage oral appliance therapy for obstructive sleep apnea.
Scope of Practice
Sleep apnea diagnosis and treatment planning remain with the referring physician. Dr. Barzilay manages the dental components exclusively, in direct communication with your office.
Evaluates dentition, jaw anatomy, and TMJ function to determine OAT suitability and identify any dental contraindications.
Selects the appropriate FDA-cleared device based on anatomy and severity. Multiple appliance options available — not a single brand.
Progressive mandibular advancement to the therapeutic position, balancing airway patency, comfort, and joint tolerance.
Arranges or co-ordinates follow-up sleep testing to confirm AHI reduction. Written efficacy report provided to the referring physician.
Regular monitoring for occlusal changes, TMJ symptoms, and appliance wear. Bite records taken at each annual visit.
Written reports at appliance fit, post-titration, and after follow-up sleep studies. Available for phone consultation on complex cases.
Referral Criteria
The ideal OAT candidate has an established OSA diagnosis and either prefers an alternative to CPAP or has tried CPAP without success.
AHI 5–30, symptomatic — OAT is a first-line AASM-endorsed therapy.
Documented CPAP trial with mask intolerance, aerophagia, or claustrophobia.
Machine data showing <4 hrs nightly use with residual symptoms.
Informed patient who understands both therapies and wishes to trial an appliance first.
Disruptive snoring without OSA — OAT is effective and well-tolerated.
With physician co-management and objective monitoring, OAT may be an option.
Discuss with Dr. Barzilay before referring; may be a relative contraindication depending on severity.
OAT requires adequate dentition for appliance retention. Denture wearers require case-by-case assessment.
Patients with AHI >30 and significant cardiovascular comorbidity require close co-management and objective efficacy confirmation.
OAT is not appropriate for central or complex apnea. Obstructive component must be documented.
