Correction of mild bimaxillary protrusion can be achieved by full retraction of the arches in a single stage, using intra-alveolar miniscrews, which are placed in the region between first molars and second premolars.
How do you fix a protruding mouth?
In mild and moderate cases, protruding teeth can be fixed with clear aligners. In mild cases where the protrusion is up to 2mm, clear braces can either move the lower teeth forward, or create more space for the upper teeth to move backwards.

How do you fix maxillary Prognathism?
How is prognathism treated? An orthodontist can adjust a protruding jaw and misaligned teeth by using braces. They work closely with oral surgeons who can fix protruding jaws with orthognathic surgery. You might choose to have this done to correct misaligned teeth or for cosmetic reasons.
How much does Bimaxillary protrusion surgery cost?
Without insurance, the typical costs of jaw surgery to correct an underbite can run from $20,000 to $40,000. Costs are usually lower if surgery is only needed on one jaw.

Some people are simply born with a lower jaw whose shape or position puts pressure on their teeth, pushing them forwards. Other causes include having larger teeth than normal, and overcrowding. If your teeth are large for the size of your mouth, they can appear to protrude.
Is prognathism curable?
Prognathism, if not extremely severe, can be treated in growing patients with orthodontic functional or orthopaedic appliances. In adult patients this condition can be corrected by means of a combined surgical/orthodontic treatment, where most of the time a mandibular advancement is performed.

Upadhyay in 2008 RCT compare treatment of bimaxillary protrusion with extraction of 4 premolars using conventional anchorage or TAD with Enmass retraction and found that i. TAD is better anchorage and the reduction of protrusion was high in TAD group ii. Also the TADs group showed a reduction in the VH due to intrusive effect of the TADs. iii.
