Dr. Simmons’ Research in Encino & San Fernando Valley

Dr. Simmons’ research study has been approved by the Western Institutional Review Board.

This is a reflection of the dedication and interest of Dr. Simmons in helping patients, as it takes considerable commitment to receive this type of research approval. 

This research project evaluates the workflow of an auto-titration mandibular positioner in helping subjects, under the care of a dentist, decide if an oral appliance would be helpful to them in treating their obstructive sleep apnea. An auto-titrating oral appliance moves the mandible in tiny increments during sleep, so as not to disturb the subject. The movements of the mandible are within the normal range of motion of each individual subject. The movements are determined by a computer algorithm and are based upon continuous feedback from the sleep testing equipment worn at the same time and connected to the adjustable mandibular positioner. Information used in the algorithm includes airflow from each nostril, pulse rate, oxygen saturation, breathing effort and other data. This study helps determine if the subject’s sleep apnea can be managed by an oral appliance. The study also gives information as to the best position for the mandible to enable that subject’s best breathing during sleep. This is landmark information that is difficult to find otherwise. Similar equipment has been used in the past few years in limited sleep laboratory settings controlled by a sleep technician but has not been available as a home device in the U.S.   Dr. Simmons office is one of only two current sites in the U.S. approved to use this equipment as part of a study protocol.

I Actually Look Forward to Dental Visits! True! I have been seeing Dr. Simmons biannually for over 20 years and every single visit without exception has been up to the highest standard in every way. From the moment you walk into his beautifully appointed office you are met with genuine smiles from courteous office staff. In 20+ years I’ve never had to wait but a few moments before being seen. Dr. Simmons is kind, empathetic, adept at making you feel at ease but most importantly he is gentle. He employs awesome dental hygienists who are also gentle, kind, and very professional in demeanor and approach to handling patients. Dr. Simmons office staff members from front to back are exceptional with their pleasing personalities and willingness to be helpful with all matters. It is always a pleasure indeed to see my Dentist!

A Doctor That Cares. My jaw hurt, headaches were awful, and the inside of my mouth looked like hamburger…not in a good way.
Dr. Simmons treated my TMD (temporomandibular joint disorder) and the relief is fantastic. He is a problem fixer….he figures out creative ways to treat nearly impossible ailments.

If you are looking for one of the best Dentists… I recently became a patient of Dr Simmon’s after facing numerous issues ranging from sleep apnea, jaw/tooth pain as well as needing a replacement crown on a moler. After being referred to Dr Simmons by my internist who holds him in the highest regard, I had immediate confidence in his diagnostic abilities, highly technical skills as well as the thorough and compassionate manner in which he and his lovely staff cares for his patients. If you are looking for someone who will provide you the highest level of care avail from basic dentistry to complex sleep issues, you should absolutely make an appt with Dr. Simmons.
