Treatment outcomes of orthodontic treatment, corticotomy-assisted orthodontic treatment, and anterior segmental osteotomy for bimaxillary dentoalveolar protrusion
. Plast Reconstr Surg 2007;120:1027-36.
An increased procumbency of the upper lip and convex profile are seen due to overjet of upper incisors in patients with Class II Division I malocclusion, or Class I bimaxillary dentoalveolar protrusion
. Orthodontic treatment of such patients aims to reduce teeth proclination and to improve the relation between the teeth and lips, and thus provide the patient with a more linear profile (1).
Effects of bimax and segmental surgeries for correction of bimaxillary dentoalveolar protrusion
class I on soft tissue parameters: upper lip thickness and curvature, nasolabial angle and nasal prominence.
Also, the cephalometric analysis indicated bimaxillary dentoalveolar protrusion
with protruded upper and lower incisors.

The objective of this study was to see the effect of lip morphology in the study sample presenting with bimaxillary dentoalveolar protrusion on normal skeletal pattern.
This article reports on a cross sectional analytical study that was conducted on subjects presenting with bimaxillary dentoalveolar protrusion. The aim of this study was to see the effect of lip morphology in the development of bimaxillary dentoalveolar protrusion on normal class I skeletal pattern.
The study was based on cephalometric analysis and it involved 50 subjects presenting with bimaxillary dentoalveolar protrusion on skeletal class I pattern.
