Abstract The cranial base has always been a subject of special interest in the field of Orthodontics, as its growth and development is interrelated to the development of the face. Anatomically, it is divided into two limbs; the anterior and the posterior limbs which meet together at the sella turcica to form a flexion commonly known as the cranial base angle. It is evident that the maxillary complex is attached to the anterior cranial base, while the mandible articulates with posterior cranial base through the temporomandibular joint. Therefore, it is thought that the cranial base as a whole plays a major role in affecting how the maxilla and mandible relate to each other in both anteroposterior and vertical directions, hence affecting the whole facial skeletal pattern and appearance. The relationship between the cranial base orientation, facial proganthism and jaw base relationship has been investigated by numerous scholars in the past few decades. However, their results have been always inconsistent and inconclusive with each other leaving this conflicting matter in debate. Therefore, this study was performed to assess the relationship between the cranial base flexion and measurements of both maxillary and mandibular jaw bases among subjects of different skeletal patterns. The sample involved in this study included lateral cephalometric radiographs of 180 adult Egyptian orthodontic patients of both sexes and of different skeletal malocclusion patterns who attended for treatment at the Orthodontic Department at the Faculty of Dentistry, Tanta University and some other private orthodontic clinics. |
