Cephalometric analysis is a cornerstone of modern orthodontics, allowing for precise evaluation of craniofacial relationships. Identifying key landmarks on a lateral cephalometric radiograph is essential before applying any analysis. These landmarks provide the foundation for constructing lines and planes, enabling accurate linear and angular measurements. OrthoAnalyser streamlines this process, offering unparalleled precision and ease.
Below are the critical cephalometric landmarks, along with their definitions and clinical significance. Each point plays a crucial role in constructing the planes and angles that form the basis of cephalometric evaluation.
The midpoint of the sella turcica, a saddle-shaped depression in the sphenoid bone, marks the posterior boundary of the anterior cranial base. It serves as a key reference point for analyzing cranial base relationships.
This is the most anterior point of the frontonasal suture, marking the anterior boundary of the anterior cranial base. It is vital for evaluating facial proportions and symmetry.
Located at the deepest point of the concave profile of the maxilla, between the anterior nasal spine and the alveolar crest. Point A is a critical landmark for assessing maxillary skeletal relationships.
Found at the deepest point of the concave profile of the mandible, between the chin and the alveolar crest. Point B is used to evaluate mandibular skeletal positioning relative to the maxilla.
The highest and outermost point of the external auditory meatus, serving as the posterior landmark for the Frankfurt horizontal plane, a key reference in cephalometric analysis.
This point is located at the intersection of the posterior border of the ramus and the base of the skull. It aids in analyzing mandibular growth and alignment.
The lowest and most anterior point of the orbital rim, forming the anterior landmark for the Frankfurt plane, used for analyzing craniofacial orientation.
The most anterior and inferior point of the chin. It is crucial for evaluating vertical and sagittal skeletal relationships.
The most inferior point on the mandibular symphysis along the midline. It helps determine mandibular height and chin position.
The most anterior point on the chin, significant for assessing mandibular prominence and profile.
Located at the most posterior and inferior point on the angle of the mandible, this landmark is essential for analyzing mandibular shape and orientation.
The tip of the bony posterior nasal spine along the midline, marking the posterior boundary of the nasal cavity.
The tip of the bony anterior nasal spine along the midline, a reference point for evaluating maxillary positioning and nasal structure.
The tip of the crown of the most anterior maxillary central incisor, a landmark for dental alignment and occlusal analysis.
The apex of the root of the most anterior maxillary central incisor. This point aids in root positioning and angulation assessments.
The tip of the crown of the most anterior mandibular central incisor. It helps evaluate lower dental alignment and occlusion.
The apex of the root of the most anterior mandibular central incisor, important for root orientation analysis.
The intersection point between the nasal septum and the upper lip along the mid-sagittal plane. This point is critical for soft tissue profile evaluations.
The most anterior point on the soft tissues of the chin, used to assess the soft tissue profile and facial aesthetics.
