Non-surgical treatment of anterior open bite
Patient is 28 years old. She had already undergone orthodontic treatment in her teens (11.5 to 14.5 years). She underwent genioplasty 2 months after removal of fixed appliances. Photos taken 4 years (in 2010) after the braces were removed showed a normal overbite.
In 2015, she consulted a prosthodontist in the Montreal area who took charge of her and fabricated a balanced occlusal plate with coverage of all occlusal surfaces.
She returns to me in 2019 after seeing 2 orthodontists and an oral surgeon who recommended orthodontic treatment and orthognathic surgery.
I explain that it’s a good solution, but I can offer her an alternative treatment with anchoring minivis at both arches.
She accepts this non-surgical treatment.
The slides show mechanotherapy.
The minivis were installed at the 11th week of treatment.
The buccal minis between the premolars had to be replaced and repositioned between the upper incisors.
Progressive radiographs showed vertical skeletal changes of the order of 5 mm in terms of vertical reduction.
Intrusion of the upper and lower posterior teeth resulted in a mandibular plane closure (FMA) of 3.6°. The occlusal plane was rotated counterclockwise by 8°.
Comparative profile photos show clear improvement.
The frontal view of the smile shows normal exposure of the anterior teeth and a consonant arch with the lower lip.
Treatment is not yet complete, but the evolution is definitely favorable.
The advent of anchorage minivis enables corrections that once required surgery.
