Assessment of Skeletal and Dental Pattern of Class II Division 1 Malocclusion with Relevance to Clinical Practice
Antanas Sidlauskas, Vilma Svalkauskiene, Mantas Sidlauskas
Class II division 1 malocclusion represents the most common skeletal discrepancy which orthodontists see in daily practice. The understanding of the morphology is a key element in planning dentofacial orthopedic treatment for this type of malocclusion. The purpose of the present study was to examine prepubertal children with Class II division 1 malocclusion and to evaluate maxillary and mandibular skeletal positions in comparison with normal growth standards by means of cephalometric measurements used by clinical practitioners. For the study casts and cephalograms of 86 consecutive patients with Class II division 1 malocclusion were used. The Class II division 1 malocclusion demonstrates broad variation in its skeletal and dental morphology. The retrognathic mandible (60%), maxillary prognathism (55.8%) and reduce vertical skeletal jaw relationship is the most common characteristic of Class II division1 malocclusion.
The optimal correction of the anteroposterior and vertical dental and skeletal discrepancies could be designed on the base of individual diagnosis for every Class II division 1 patient.
Key words: Class II division 1 malocclusion, cephalometrics, mandibular retrognathism.
