What is X-ray cephalometric measurement
Normal value
No abnormal shadows and patterns were found during the inspection.
Clinical significance
Abnormal results: 1. Research on craniofacial growth and development: X-ray cephalometric measurement is an important method to study craniofacial growth and development. It can also be used for the measurement and analysis of individuals in different periods, and for longitudinal study of craniofacial growth and development.
2. Diagnosis and analysis of dentition and craniofacial deformities: by measuring and analyzing individuals with craniofacial deformities through X-ray cephalometric measurements, it is possible to understand the mechanism, main nature and location of the deformity, whether it is a skeletal deformity or an occlusal deformity. Deformity can make a correct diagnosis.
3. Determine the corrective design of malocclusion: From the X-ray cephalometric analysis and research, it is concluded that the normal joint relationship can exist in various craniofacial skeletal structure relationships, and the position of some teeth can be under a certain maxillofacial structure. It is stable. Therefore, after measuring and analyzing the dental jaw and craniofacial structure, according to the mechanism of misalignment, the ideal position of the jaw position and tooth correction can be determined, so as to formulate a correct and feasible correction plan.
4. To study the changes in the morphology and structure of the dentition and craniofacial during and after the correction: X-ray cephalometric measurements are also often used to assess the changes in the morphology and structure of the dentition and craniofacial during the correction process, so as to understand the mechanism and mechanism of the orthodontics. Stability and recurrence after correction. For example, the effects and changes of the extraoral anchorage lip arch correction device and mandibular chincup correction device on the dental jaw and craniofacial structure were only clarified and clarified after the use of X-ray cephalometric measurements.
5. Design of diagnosis and correction of surgical orthodontics: Analyze the soft and hard tissues of patients with severe craniofacial deformities who require surgical orthodontics through X-ray cephalometrics, and obtain the main mechanism of the deformity to determine the location of the operation, Methods and the number of jaws to be moved or resected. At the same time, X-ray cephalograms are used for cutting to simulate the position of the postoperative teeth and jaws to obtain a facial map of the postoperative dental jaw and craniofacial relationship, which is orthodontic surgery Provide a sufficient basis, thereby improving its diagnosis and correction level.
6. Mandibular function analysis: X-ray cephalometric measurement can also be used to study mandibular movement, palatal function during language pronunciation, and functional analysis of the rest gap. It is also used for the functional study of the movement trajectory of the mandible from the resting position to the occlusal condyle and jaw position.
People who need to be checked: people with abnormal craniofacial growth and facial deformities.
