Skeletal class II has always been a challenge in orthodontics and ofen needs assistance of surgical orthodontics in nongrowing
patients when it presents with severe discrepancy. Difculty increases more when vertical dysplasia is also associated with sagittal
discrepancy. Te advent of mini implants in orthodontics has broadened the spectrum of camoufage treatment. Tis case report
presents a 16-year-old nongrowing girl with severe class II because of retrognathic mandible, and anterior dentoalveolar protrusion
sagittally and vertically resulted in severe overjet of 13 mm and excessive display of incisors and gums. Both maxillary central incisors
were trimmed by general practitioner few years back to reduce visibility. Treatment involved use of micro implant for retraction and
intrusion of anterior maxillary dentoalveolar segment while lower incisors were proclined to obtain normal overjet, and overbite
and pleasing sof tissue profle. Smile esthetics was further improved with composite restoration of incisal edges of both central
incisors.
1. Introduction
Te most common reason to approach an orthodontist is
esthetic concern which is compromised by malocclusion [1].
Malocclusion, which can be skeletal or dental in origin [2],
is present in every society but with variable prevalence [3–5].
Class II div 1 is the most prevalent malocclusion in Pakistani
population [6]. Depending on the severity, class II div 1
not only causes esthetic and functional problems but also
results in psychological disturbances [7]. Te treatment of
class II involves growth modifcation in growing patients
and camoufage in adults, if the skeletal discrepancy is mild
to moderate. Complexity of treatment increases with the
severity of sagittal discrepancy particularly when it coexists
with maxillary vertical excess [8].
Maxillary vertical excess, which also can be skeletal or
dentoalveolar type, presents with excessive visibility of upper
incisors and excessive display of gingiva on smiling (gummy
smile) [9]. More than 4 mm of gingival display is considered
excessive and unattractive by patients and also by general
dentist [10]. Irrespective of the cause, gummy smiles are
rarely corrected with conventional mechanics and ofen
orthognathic surgery is recommended [10]. However skeletal
anchorage system has now widened the spectrum of ortho-
dontics and is also very well accepted by patients [11, 12].
Mini screws can provide maximum anchorage to retract and
intrude dentoalveolar segment simultaneously.
Te following case is a severe skeletal class II with anterior
maxillary dentoalveolar extrusion, which was treated with
orthodontic camoufage rather than orthognathic surgery.
