Maxillary incisor proclination
effect on the position of point A in class II division 2 malocclusion.
This change in the lower incisors might be due to the use of lip bumper with Teuscher activator combined that might break the muscular equilibrium zone and enhanced the proclination
of lower incisors.
The most prominent features recorded were frontal bossing, seen in 54% cases, Parietal bossing in 88%; Depressed nasal bridge in 70% ; Pallor of oral mucosa in 84%; Intra oral pigmentation in 88%; Proclination

First premolar extraction effects on upper airway dimension in bimaxillary proclination
A correction of fractured anterior teeth to their proclination
This assertion was supported by Nielsen who found that the FR did not induce proclination
of the mandibular incisors relative to the cranial base.
Orthodontic treatment may be resumed after improvement of periodontal disease; however, in cases of excessive incisor proclination
, special attention must be paid during new follow-ups in order to avoid recurrent periodontal disease.
Shortened chair time and slightly less incisor proclination
appear to be the only significant advantages of self-ligating systems over conventional systems that are supported by the current evidence.
The presence of excessive labio-axial inclination of the anterior teeth was considered as proclination
and as anterior open bite when the anterior teeth in the maxilla did not occlude those in the mandible.
Treat- ment of class II div 2 cases of growing patients with moderate to severe skeletal discrepancy usually involves proclination
of the upper labial segment, converting the incisal relationship to a Class II division I malocclusion.
The morphological arrangement of the teeth in the sagittal plain has been related to the slope of the articular eminence, craniofacial morphology,3 lower incisor proclination
, the incisor overbite,4 the molar cusp height and lower arch circumference.
They are more vulnerable as compared to other teeth to such injuries owing to their exposed nature and the chance of injury further increases as their anterior proclination
