Cephalometric Analysis Flashcards
(55 cards)
Consist on tracing points on acetate paper and from these points the desired angular and linear values are measured to obtain a concise and understandable description of the craniofacial pattern and classify the patient, this is going to helps us to identify what the objectives of the study will be, choose the treatment modality and predicting its success.
Cephalometric analysis
The cephalometric analysis Is responsible to study the horizontal and vertical relationships of the most important functional components: (8)
the skull and cranial base, the maxilla, the dentition and the upper alveolar processes, the mandible, the dentition and the lower alveolar processes.
Serial cephalometric X-rays obtained before, during, and after treatment can be superimposed to study changes in the position of
Jaws and teeth

Is essential to carry out the correct treatment planning. This must be done based on a thorough study of the patient and the problems they present, both bone and dental
Orthodontic diagnosis
The orthodontic diagnosis deals with recognition of the various characteristics of the maloclussion. Based on:
- Patient interview
- Clinical examination
- Evaluation of the diagnostic records
Mention the 4 medical conditions that contraindicate the use of Orthodontic appliances:
- Osteoporosis
- Cáncer
- Diabetes
- Rheumatic fever
Dx records:
Lateral
Panoramic
Dental cast
Intra/extra oral pictures
Describe what are some of the most important thigs that we can see in the intraoral pictures that can be helpful for the orthodontic diagnosis:
The general condition of the hard and soft tissues of the mouth (including the periodontium) and the functional status of the patient’s occlusion.
open bite or close bite
Describe what are some of the most importante thigs that we can see in the extraoral pictures that can be helpful for the orthodontic diagnosis:
((FSSymStPmDevRe))
facial shape,
symmetry,
soft tissue harmony and
the state of the perioral muscles.
This determines deviations from normal with respect to a patient’s sagittal, vertical, and transverse maxillofacial relationships and
evaluates the relationship of the dentition and facial structures.
Steiner analysis:
- skeletal analysis
- dental analysis
- soft tissue analysis
