Orthodontic management
of a Class-III openbite cleft lip-palate patient:A case report
Introduction: Cleft lip-palate is one of the most common
congenital anomalies of the orofacial structure. The purpose of this case
report is to present the multidisciplinary treatment of a nonsyndromic
unilateral complete cleft lip and palate patient.
Case: A 25-year-old female patient presented
to our clinic with a chief complaint of an unpleasant smile esthetics.Intraoral
clinical examination showed bilateral class III molar and class II canine
relationship, openbite,total circular crossbite,congenital deficiency of upper left lateral and
supporting alveolar bone in cleft area,dental midline discrepancy. Convex facial profile with a
flattened nasal tip, shortened columella, and diminished malar prominence were
observed in the extraoral examination. Radiographic examinations revealed
skeletal class III pattern with maxillary retrognathia,vertical growth pattern
with transversal deficiency in the maxilla and retroclined
upper/lower incisors.
Discussion:
The aim of
the treatment was to correct crossbite with maxillary expansion, increase bone
density with alveolar graft operation, correct open bite, ensure class I
relationship and functional occlusion, and improve facial and dental
aesthetics. QuadHelix was applied for slow maxillary expansion to correct the
transversal discrepancy. Following the expansion, alveolar bone graft operation
was performed. In order
to increase anchorage in the posterior region a transpalatal arch was used. By
distalization of the right premolars, leveling was achieved in the anterior segment.
Adequate overbite was achieved by retraction and extrusion of the incisors.
Conclusion: With multidisciplinary treatment
methods, aesthetic, satisfactory results, and a stable and functional occlusion
can be achieved in non-growing cleft lip and palate patients.
