Introduction
Recent reports have suggested that anomalies involving the maxillary dentition can sometimes occur in combination. The aim of the study was to investigate combinations of maxillary dental anomalies relating to occlusal and skeletal factors which could suggest a ‘syndrome-like’ aetiology.
Method
This report is based on observations of study models and cephalograms of individuals exhibiting dental anomalies or malocclusion traits related to maxillary or maxillary arch development. A series of nine dental and skeletal anomalies was defined. A possible inter-relationship between the dental factors as well as a correlation with the skeletal malocclusion traits and skeletal factors was investigated.
Results
Of the 253 cases examined, 157 demonstrated single dental symptoms; the remainder demonstrated a combination of at least two or more. Dental and occlusal anomalies in maxillary development were usually associated with bi-maxillary jaw retrognathism and a low mandibular ramus height, indicating a vertical mandibular developmental pattern.
Conclusions
Maxillary anomalies based on the finding of aplasia, eruption problems or crossbite could occur in combination and be associated with constricted skeletal development of the palate or atypical mandibular morphology. It is proposed that these findings suggest the existence of a
