invisible brace case

Below is a case treated with the latest brace on the market the incognito invisible lingual brace, this case was treated without taking any teeth out. A lingual brace is a brace which is fitted on the inside of your teeth.  Notice when the patient bites together before treatment she has a space between the upper and front teeth, and mild crowding, at the end of treatment the teeth are aligned and the gap between the teeth is closed.

The advantages of the invisible lingual brace , is  that more complicated  cases can be treeated this way,  where an  invisalign  brace may be contraindicated. One of the questions commonly asked is does it interfere with the tongue,  it usually takes 3 days for the tongue to get used to the brace. As each brace is customised to your mouth ( see our section of the blog on how this brace is made), which makes each bracket  as low a profile as possible. This brace is literally the ” Rolls Royce” of braces, and enables more cases to be treated without taking any teeth out with the minimal of discomfort.   Trishan Malhi at the Park Dental Clinic is currently offering this treatment, our contact details are tel: 01332 299700, email : info@theparkdentalclinic.co.uk 

 

Lingual Braces (Incognito)

     

Advantages of Lingual Treatment with Incognito™
Appliance system fabricated to deliver individually defined treatment objectives     

To begin an Incognito therapy it is necessary to take a two-phase  impression. High quality impressions are extremely important to ensure a high quality appliance. The plaster models produced from this impression are used to prepare an individualized therapeutic setup that is created by cutting the teeth and setting them up in to the target position in wax.     

An articulator and a wax bite are used to simulate the correct jaw relationship.     

     

      

      

      

A high-resolution optical 3D scanner permits non-contact scanning of the therapeutic setup. The result of the scan is a 3D digital representation of the teeth consisting of many thousands of minute triangles that can be documented and processed in the computer

Creating Individualized Bracket Bases       

Specialized CAD/CAM software is used to design and build customized brackets. The fabrication process begins with the creation of individualized bases being customized to the lingual surfaces of the patient’s teeth. Because of the extreme accuracy of the scan, the bases mold precisely to the teeth. Large pad surfaces provide greater bond strength and make them easy to place on the teeth for bonding and re-bonding.   

    

    

    

     

                                               

Positioning the Bracket Bodies     

After the design of the bracket bases, the appropriate bracket bodies are selected from the digital archive and arranged by the software. The vertical height, angulations and torque are preset into each bracket. In this way the patient’s individual prescription is designed into the brackets.     

     

      

      

      

      

      

      

Each wing is adjusted to make the bracket profile as low as possible while allowing room for elastics to be attached to the bracket.       

     

      

      

                   The individualized brackets conform to the dental anatomy.

Bracket Manufacturing     

Wax patterns of the customized brackets are created using rapid prototyping machines. The patterns are then placed in an investment cast, burned out and a dental gold alloy is poured into the cast to create the brackets. After casting the brackets are tumbled and polished until they are smooth to ensure high patient comfort.     

     

      

      

      

      

                          

      Gold brackets are placed on the original malocclusion model 

     

  

  

 
 
 

   

 
 
 
 
        

           Indirect bonding trays are made from the model      

     

      

      

      

      

      

      

Wire Fabrication      

The wire geometry is calculated by the CAD/CAM program and then sent to a machine for fabrication. Each wire in the sequence has the same geometry targeted to the final position of the teeth.
