Computer Guided TMD Therapy for the DFW Metroplex

Dr. Allen Sprinkle is one of the first dentists in the United States to be certified by Dr. Robert Kerstein as a Fellow of the Center for Neural Occlusion.

DTR,  Disclusion Time Reduction Therapy, was developed by pioneer Dr Robert Kerstein, using T-scan computer bite analysis (Tekscan-Boston, Massachusettes) and the BioResearch EMG (Bio Research-Milwaukee).

The technology allows a dentist to observe precise measurements of pressure and time on the teeth. Disclusion Time, or the time it takes to separate the teeth, is combined with with the pressure on the teech, triggers the pain center in the brain to create hyper muscle activity.  This causes head, neck and facial pain and results in damaged to the joints of the jaw.

The treatment approach using DTR technology provides comprehensive and conservative care that brings the most complete and lasting results.   It is for those reasons, that Dr. Sprinkle offers this new and exciting therapy known as Disclusion Time Reduction Therapy.  It has been particularly helpful in the treatment of TMD and provides a faster, more permanent result, than most appliance based treatments.

The Benefits of Disclusion Time Reduction Therapy

Disclusion Time Reduction Therapy uses computerized occlusal analysis technology and eletromyography (EMGs) to measure the duration of frictional forces on the teeth every 0.003 of a second. The technology is both reproducable and quantifiable and helps patients achieve results that virtually eliminate the need for other treatment options.  This is especially true for patients who consistently grind their teeth.

How Many Treatments Are Needed?

Treatment time with Disclusion Time Reduction averages 3  to 12 visits, depending on severity.  Based upon a nine year follow up study, results last years past the initial treatment.  Recent study also support the effectiveness of the treatment and show that Disclusion Time Reduction provides patients with a more comfortable life, without splints,  soft food diets and physical therapy.  The study also showed a long term reduction of 90 per cent in pain medications.

Dr. Sprinkle appeared on Joni's Table Talk TV show sharing his experience using DTR and his patients experiences.  To view the episodes click below.  You can also visit Dr. Sprinkle's Facebook page, Headache Relief Alternatives, or his You Tube Channel.  And don't forget to like us and share the videos with others.

Dr. Sprinkle (center) had lunch with Joni Lamb of Daystar Television Network and her guests Dr. Andrew Wakefield (left) and Del Bigtree (right) of the movie "Vaxxed."

Wakefield and Bigrtree, along with Dr. Sprinkle's friend and patient Kelly Gallager, produced the accalimed documentary "Vaxxed" about Center for Disease Control whistleblower Dr. William Thompson.  He exposed fraudulent research used to promote the safety of the MMR vaxccine which has resulted in the epidemic rise in autism.

Dr. Wakefield talked about the largest consumer recall ever recorded involving defective airbags, which have killed 10 people.  Reported by network news,the airbag manufacturer's recall involves more than 100,000,000 vehicles and has been removed from the market due to "safety reasons."  Wakefield asked the question, "Where is the outrage for the over 100,000 families devastated by the diagnosis of autism each year?"  Seldom, Wakefield noted, is there a word about the cause behind this life-changing condition. 

Why has the media remained silent?  Why hasn't the government initiated a recall? Where is the justice for these families? Is it because they don't want to loose "big Pharma's" advertising dollars?
