ALVEOLOCONDYLAR PLANE Meaning and
Definition
-
The term "alveolocondylar plane" refers to an anatomical reference plane used in dentistry and orthodontics to assess the spatial relationship between the maxilla (upper jaw) and the mandible (lower jaw). It is a horizontal plane that is defined by the alignment of specific landmarks, namely the midpoint of the condyles of the temporomandibular joints and the highest points of the alveolar ridges (where the teeth are located).
This plane is considered significant as it helps determine the occlusal relationship between the upper and lower jaws, particularly in the context of orthodontic treatment planning and evaluation. By assessing the angulation and inclination of the alveolocondylar plane, dentists and orthodontists can better understand the positioning of the jaws and the coordination of the teeth within the oral cavity.
Furthermore, the alveolocondylar plane acts as a reference for cephalometric analysis, which involves the measurement of various facial and skeletal structures using radiographic images. It helps quantify the vertical and sagittal discrepancies between the jaws, aiding in the diagnosis of conditions such as skeletal malocclusions, asymmetries, and abnormal crowding.
Overall, the alveolocondylar plane is an essential anatomical reference in dentistry and orthodontics, allowing clinicians to assess the relationship between the maxilla and mandible, and aiding in the planning, evaluation, and treatment of various occlusal and skeletal abnormalities.
