2018 Annual Session Conference

New Horizons in Orthodontics

May 5, 2018 2:05pm ‐ May 5, 2018 2:50pm


Preformed Clark Twin Blocks: A new design and protocol for fixed or removable Twin Blocks improves patient comfort and compliance and can be integrated with fixed appliances. Preformed lingual wires link the occlusal blocks with minimal interference to speech and comfort and this simplifies construction and management of Twin Blocks. TransForce Lingual Appliances represent a revolution in interceptive orthodontics in all classes of malocclusion from mixed dentition to adult therapy and may be combined with fixed appliances or clear aligners. Transverse and sagittal appliances are pre-activated with enclosed nickel titanium springs to achieve amazing changes in arch form using ‘patient friendly’ invisible lingual appliances.

Learning Objectives:

  • Simplify treatment of Class II malocclusion using preformed removable or fixed Twin Blocks.
  • Transform your interceptive treatment using aesthetic, comfortable and efficient appliances to deliver light physiological forces.
  • Integrate fixed and functional therapy and enhance treatment objectives with invisible appliances.
