Dr. Patch, a qualified physician and dental surgeon with over forty years practice, has undertaken the necessary sub-specialty training to enable him to help diagnose and treat OSA in conjunction with the sleep specialist doctors and the respiratory therapists at the sleep lab in Royal Inland Hospital. He has taken the necessary courses to qualify as a “Sleep Dentist” and is qualified to fabricate and titrate mandibular repositioning appliances for the treatment of Obstructive Sleep Apnea. He initially trained with Doctor Wayne Halstrom of the Vancouver Institute of Sleep Medicine where he qualified to fabricate and titrate the ‘Silencer’, a custom fitted oral sleep appliance designed and fabricated by Dr. Halstrom since the 1990’s. While the ‘Silencer’ is no longer available due to technical and material availability problems, several thousand of these oral appliances are continuing to provide excellent treatment for their existing sleep apnea owners. For the past year, both Dr. Halstrom and I have been providing a set of new sleep appliances manufactured by the SomnoMed Company of Australia with excellent results.
