Solitary Median Maxillary Central Incisor Syndrome (SMMCI
Syndrome) is a rare developmental disorder consisting of
morphological defects that mainly affect structures in the
midline of the body. The aetiology of this syndrome has
not been fully explained, and SMMCI syndrome is observed
more frequently in females. The presence of a solitary
median maxillary incisor in the midline of the maxilla is
a typical trait in the stomatognathic system, and this anomaly
is found in both deciduous and permanent dentition.
Regarding developmental abnormalities accompanying
a solitary incisor with an atypical structure, the most
common ones include: lack of the frenulum of the upper
lip, deformations in the nasal cavity and cranial base, heart
defects, cleft lip and palate, and mental disability of various severity. Aim. The aim of this work is to present the
characteristic traits of a solitary median maxillary central
incisor syndrome on the basis of a case study of a 9-yearold
female patient and the analysis of available literature.
Material and methods. The literature review was
performed using the PubMed database and the following
key words: incisor, maxilla, syndrome, development, SMMCI
syndrome. Case report. When the clinical examination and
medical history were performed the patient was diagnosed
with signs of solitary median maxillary central incisor
syndrome. The outcomes of a computed tomography scan
confirmed choanal stenosis. Except for allergies to animal
hair and grass, the patient did not suffer from any systemic
diseases. On the basis of a clinical examination and analysis
of additional tests the following diagnosis was made:
I skeletal class, complete distocclusion with incisor
protrusion, partial lateral bilateral cross bite and dental
abnormalities. Summary. Patients diagnosed with SMMCI
syndrome often require complex care provided by specialists
from various fields of medicine and dentistry, due to the
possibility of coexistence of numerous developmental
abnormalities involving different body structures. (Molska
