2nd Quizz Flashcards
What does the Diagnostic Records include?
- Lateral X-Ray
- Panoramic X-ray
- Extra oral & intraoral photographs
- Dental casts
What does ortho takes care of?
Dx, prevention, interception and tx of all malocclusions
Elements based for an ortho dx:
- px interview
- clinical examination
- Evaluation of the dx records
Mention the 4 medical conditions that contraindicate the use of orthodontic appliances
osteoporosis
Cancer
Diabetes
Reumatic fever
Extraoral and intraoral images (photographic analysis).
May include digital or video images to supplement the clinical findings
Dental casts (digital models).
To assess the inter-arch and intra-arch relationship of the teeth, to help determine arch length and to assess arch symmetry
To assess the condition and developmental status of the teeth and associated structures, and to identify any dental anomalies or pathology
Panoramic X-ray.
Allow the evaluation of the size, shape, and positions of the craniofacial structures and dentition, and in the identification of skeletal anomalies or pathology.
Cephalometric X-ray.
May be used as an alternative source to obtain dentofacial information, but is not routinely required for orthodontic X-rays*.
Cone-Beam computer tomography (CBCT).
Assess the general condition of the hard and soft tissues of the mouth (including the periodontium) and the functional status of the patient’s occlusion
Intraoral pictures
Determine 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.
Extraoral pictures
Mention de facial shapes
Oval
Round
Square
Profile types
straight
Convex
Concave
Profile that indicates a Class II jaw relationship, which may result from a maxilla that projects too far forward or mandible too far back.
Convex profile (A
indicates that the relationship of the maxilla and mandible is in harmony.
Straight profile (B)
indicates a Class III relationship, which may result from a maxilla that is too far back or a mandible that protrudes forward.
Concave profile (C)
Type of X-ray to assess dental anomalies.
Intraoral
X-ray to assess the dental condition and adjacent structures
Extraoral
studies the craniofacial growth patterns is mainly used to assess dentofacial proportions and to evaluate the anatomical bases of malocclusion.
Cephalometry
1- 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 dx record
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:
- Condition of the tissues
- functional status of the patient’s occlusion
- Arch
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:
- facial shape,
- symmetry
- soft tissue harmony
- state of the perioral muscles
