Patient Details

Age: 34 years old Gender: Female Chief complain: Anterior openbite and severe mandibular joint clicking with pain


  • Anterior openbite 3-4mm
  • Slight crowding in upper anteriors
  • Class I canine and molar relationship on right side
  • Slight class II canine relation left side
  • Right condyle mild dislocation on mouth opening
  • CMD
  • Tongue thrust habit on swallowing.

Treatment planning

We will start with Aquasplint for 1.5 months to eliminate the mandibular jaw dysfunction symptoms. Bluegrass appliance will be used for 4-6 months to treat the tongue thrust habit. Then Clear aligner treatment using K Clear from K Line Europe follows in sequence. Number of aligners: Upper: 14 upper and 14 lower aligners Total 12 months treatment

Treatment objective

  • Align upper teeth
  • Treat the CMD
  • Treat the tongue thrust habit
  • Close the anterior openbite.

Results and conclusion posttreatment

Attachments were placed on the buccal teeth for intrusion. The intrusive effect of the posteriors relieved the TMJ and put condyle in a favorable position. The intrusion of the posteriors helped as well in the anterior openbite closure in only 6 months after finishing the Bluegrass appliance treatment. The Condyles position were significantly corrected and the patient doesn’t have pain nor TMJ clicking anymore on mouth opening.
