What is the Biobloc Orthotropic Appliance?

Biobloc Appliance


The Biobloc appliance is a removable orthotropic device that looks like a retainer. The Biobloc can straighten teeth and improve the jawline by slowly stimulating the jaws to grow larger. The treatment is endorsed by Dr. Mike Mew and creates more room in the mouth so teeth fit better and are less crooked. The Biobloc can stimulate the jaws to grow wider, taller and more forward. As the upper jaw grows forward, it allows more space for the mandible to move forward and grow wider. As the lower jaw moves forward, it increases the vertical height of the mouth and creates more volume. The process also decreases facial elongation. The result is more room in the mouth and nasal passageways, straighter teeth and better facial profile. Our Biobloc therapy helps our patients, not only have a better smile, but also sleep, breathe and posture in a healthier way.

Dr Adams uses the Biobloc and many other adult expanders and orthodontic appliances for children at the TMJ Sleep and Breathe Center.


Dr. John Mew and Dr Mike Mew in the Documentary, “Open Wide”

Open-Wide, a documentary about orthotropics, Mewing and Dr John and Mike Mew. The truth usually lies somewhere between what he said and she said, so we will let you be the judge. The world may not know for sure for years before the research never comes out. The British dentist licensing agency took Dr. John Mews license away years ago for bad mouthing orthodontics and saying unprofessional things about traditional orthodontics. Now the same board is hot to trot to take Dr. Mike Mews license away. Is the profession or orthodontics attempting to hide something or are the Mews really selling snake oil?


How the Biobloc works with Mewing


The Biobloc works with biological forces. Dr. Mike Mew recommends keeping your mouth closed and keeping your tongue on the palate. Dr. Mew recommends what he calls “Mewing” which is a form of tongue and mouth exercises similar to some Myofunctional Therapy exercises.

The Biobloc is only worn at night and is taken out during the day. It is not worn while eating. Oral hygiene is very easy since the appliance is removable. The treatment does not hurt because expansion pressure is very light compared to braces and conventional orthodontics. As long as the appliance is worn every night, designed properly and adjusted as advised, the treatment will go as planned.


What is our Biobloc Therapy About?


Drs Gary Adams and Viet Le welcome you to our practice. If you are looking for information about the Biobloc appliance therapy, you have found the right place. Many of our patients are children who have crowded teeth, tied tongues, and mouth breathing problems. Some also have posture and sleep disordered breathing issues. We integrate orthodontic expanders (such as Biobloc), chiropractic services, breathing exercises and myofunctional or tongue correction therapy. Our therapy helps our patients have a straighter smile, sleep better and live a pain-free and healthier life. We are located in Vienna Virginia near Tysons Corner and just outside of Washington DC.


Objectives of Biobloc Appliance Treatment:


  • Improve facial growth and profile
  • Improve smile
  • Optimize tongue function
  • Establish healthy breathing patterns
  • Create a good bite
  • Balance upper and lower jaw relationships
  • Establish healthy posture


Why Do Teeth Grow-in Crooked?


Teeth become crooked because of poor tongue function, unhealthy mouth breathing patterns and a diet consisting of foods that are too soft. This is why kids mouths and faces do not grow large enough for all their teeth to fit and bite properly. If tongue and breathing problems are not corrected, your child will fall behind again in their development 1-2 years after appliance therapy. That is right, the teeth will get crowded and crooked all over again, if the root cause of developmental problems are not corrected. Kids continue to grow till at least the age of 19.


Why Jaws and Faces Under Develop?


Poor tongue movement is the root cause of underdevelopment of the face. Tongue pressure naturally expands the mouth and lower part of the face. Tongue ties cause diminished range of motion of the tongue. The tongue does not move out far enough and cannot reach the palate easily. Tied tongues often get pointy and curl down when extended out of the mouth. There is a sequential cause and effect relationship in the following order:


  1. Tongue Tie
  2. Poor Tongue Function
  3. Under Development of the Palate and Nasal Passageways
  4. Poor Nasal Breathing
  5. Mouth Breathing


How to Release Tongue Ties


tongue tie release


Tongues can be untied with a soft tissue laser.  It is very quick, mostly painless and there is not bleeding. The dentist needs to verify the tongue is functioning correctly at the time of the procedure. Untying the tongue alone is not enough. The procedure is called a “functional tongue untie.”


What is Myofunctional Therapy


Myofunctional therapy is basically tongue physical therapy. Tongue exercises to achieve healthy movements. If tongue therapy and exercises are done with a functional untie procedure, tongue reattachment is less than 20%. Without myofunctional therapy, tongue reattachment is closer to 80%.


How to Correct Mouth Breathing Patterns


  1. Remove all Tongue Ties
  2. Myofunctional Therapy
  3. Orthodontic Expanders to correct jaw and facial under growth
  4. Breathing Exercises to restore proper nasal breathing patterns
  5. Posture Therapy with a chiropractor or qualified PT


What is our Most Popular Kids Appliance?


The Schwarz appliance  is our most popular orthodontic appliance for children. We believe in the Biobloc, but the Schwarz is more versatile and can sometimes save the patient from having to do multiple rounds of orthodontic treatment. The Schwartz is very easy to tolerate and it only needs to be worn at night. Unlike braces and other fixed expanders, the appliance does not get in the way of daily activities and is not worn during meal time. The appliance does not hurt when being adjusted.


Appliances We use for Children

  1. ALF appliance
  2. Schwarz
  3. Myobrace
  4. Twin Block
  5. Crozat
  6. Healthy Start


What are Orthodontic Expansion Appliances?


We prefer the use of the term “growth appliances.”  They are small retainer-like devices that promote growth of the jaws. The goal is to grow the jaws into a more optimal size and shape. Growth appliances work by applying a light force in the direction the jaws need to grow. They are not mechanical devices and do not cause pain. The appliance mimics tongue pressure and encourages proper tongue position. Appliance therapy is synergistic with swallowing and tongue movement.


How Long Does Biobloc Therapy Last?


Most kids only need to wear the appliances at night for 6-9 months during treatment. The appliances are usually not worn during the day or while eating. The patient is usually seen in the office every 5-7 weeks. During the office visits we will evaluate the growth, adjust the appliances and verify patient compliance. Treatment is usually performed between the ages of 5 and15 years of age.
