Parcial 2 Pt2 Flashcards
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:
- pacient interview
- clinical examination
- evaluation of diagnosis records
Mention the 4 medical conditions that contraindicate the use of orthodontic appliances:
- cancer
- diabetes
- osteoporosis
- reumatic feber
Describe what are some of the most importante things that we can see in the intraoral pictures that can be helpful for the orthodontic diagnosis:
Assess to the general condition of the hard and soft tissues of the mouth and the functional status of the patients occlusion
Describe what are some of the most important things that we can see in the extraoral pictures that can be helpful for the orthodontic diagnosis:
Determine facial shape, symmetry, soft tissue harmony and the state of the perioral muscles.

Write the 3 types of facial form:
Square
Oval
Round
Write the name of each orthodontic diagnostic records:
- lateral X ray
- Panoramic x ray
- dental cast
- intraoral and extraoral photographs
