Profile changes following orthodontic correction of bimaxillary protrusion
with a preadjusted edgewise appliance.
Large incisor retraction leads to narrowing of the upper airway in adult bimaxillary protrusion
patients.38 The extraction of upper premolars rather than non-extraction in patients decreased the pharyngeal airway space with mandibular prognathism who planned to have bimaxillary surgery.39 The ForsusTMFatigue Resistant Device (FRD) produced dento alveolar changes but did not have any significant influence on posterior airway in young adult patients.40
Malocclusions like Angles Class II div I or Class I bimaxillary protrusion
can lead to the diastemas between the teeth.
One of the study conducted in Pakistani population by Attiya and colleagues15 showed bimaxillary protrusion
with prominent chin in males which is contradicting the findings in this study.
Reports can be found that describe the successful use of ACS in the enhanced correction of severe bimaxillary protrusion
, (25) closure of complex skeletal open bites, (26) intrusions and molar uprighting combining ACS and mini-implants, 27 and optimization of treatment of patients with cleft lip and palate.
Bone development in Oriental races tends towards bimaxillary protrusion
; therefore, Oriental races have greater tooth axis bending compensating for bony protrusion.
Class I bimaxillary protrusion
is frequent type of malocclusion encountered in India.
