Open Bite: Case Study with Clear Aligners


Patient details:

Age: 34 years old

Gender: Female

Chief complaint: unpleasant gap in front and severe clicking in the mandibular joint with pain upon mouth opening.


Diagnosis:

  • Anterior open bite, 3-4mm

  • Slight crowding in the upper anterior teeth

  • Class I canine and molar relation on the right side

  • Slight class II canine relation

  • Slight displacement of the condyle when opening the mouth

  • Craniomandibular dysfunction

  • Tongue thrust during swallowing


Treatment Goal and Plan


To begin treatment, we use Aquasplint for 1.5 months to eliminate the symptoms of mandibular dysfunction. The Bluegrass appliance is used for 4-6 months to correct the habits of the tongue. This is followed by clear aligner treatment with K Clear from K Line Europe.


Orthodontic goals list: straighten teeth, treat dysfunction, correct tongue thrust and bite. Includes aligner count and 12-month duration.

Results and conclusion after open bite treatment


Attachments were placed on the buccal teeth for intrusion. The intrusive effect of the posterior teeth relieved the temporomandibular joint and brought the condyle into a favorable position.


The intrusion of the posterior teeth also helped close the anterior open bite only six months after completion of treatment with the Bluegrass appliance.


The condylar position has been significantly corrected and the patient has no pain, nor is the cracking of the jaw heard when opening the mouth.
