Technical Bulletin

• Treatment time is greatly reduced over the use of Sagittal and Bionator appliances.
• Corrects open bites.
• It correctly positions the TMJ and mandible.
• It can develop the maxilla in transverse/sagittal directions.
• It corrects facial asymmetry.
• It allows the first permanent molars to erupt to proper vertical, thus eliminating deep bites quickly.
• The occlusal plane is leveled as the alveolar vertical height of the buccal segments of both jaws increase.
• Overjets are corrected as the mandible is relocated forward.
• Improved premaxillary and bimaxillary profiles.
• Mild to moderate lower anterior crowding is corrected.

Disadvantages
The doctor may need to monitor the progress of the UltraBlock a little more closely than other appliances since there are several changes taking place at the same time. The sequence of treatment must also be carefully followed. Patients will notice some impaired speech for a short time.

Lab Requirements
Mount case and adjust for correction of planes. Create bite on a Denar/Witzig articulator and adjust to the correct Gelb 4/7 position. Send to Johns Dental for appliance fabrication along with a set of good working models.

WARNING: THEY CAN ERUPT AND PRODUCE AN OPEN BITE IF THERE IS A LACK OF SUPERVISION.

This appliance can develop the maxilla by incorporating a Sagittal or Transverse configuration into its basic design. Thus, it has all the advantages of the Sagittal, Transverse, Orthopedic Corrector, plus it is much faster. Since only one appliance is used, rather than several appliances, there is better compliance of the patient, while achieving faster and more controlled results. Additionally, it can be fixed into place by bonding above the adams clasps to the primary teeth and removed weekly by the dentist for cleaning purposes. Compliance is improved as well as learning to eat with the appliance.

The UltraBlock, shown here on a permanent dentition model, also has applications for mixed dentition treatment. The incline is used here to bring the mandible forward and the expansion screws were added to achieve additional arch width.

Appliance Variations
Basic UltraBlock- Without expansion screws
Molars covered- This is done to prevent eruption because of a mild overbite.
Molars uncovered- This version is used for a deep bite.
Transverse UltraBlock- Expansion screws are added to the basic UltraBlock style. Options with molars covered and uncovered are also available.
Sagittal UltraBlock- Two or three sagittal screws are used for gaining additional arch length/width. Options with molars covered and uncovered are also available.
