Which type of orthodontic method is characterized by assessing both the models and X-rays?

The assessment of both models and X-rays in orthodontics is referred to as diagnostic records. This method involves collecting detailed information about a patient’s dental and facial structure, which includes not only impressions or models of the teeth but also radiographs that provide insight into the underlying bone structures and overall dental alignment. The use of both types of records enables orthodontists to make informed decisions regarding the diagnosis of dental issues and the planning of appropriate treatment strategies. These diagnostic records serve as a foundational step in understanding the specific needs of the patient and play a critical role in formulating effective treatment plans.

The other options highlight different aspects of the orthodontic process but do not specifically focus on the combination of models and X-rays used for initial assessment. Expert assessments might involve professional input but aren't limited to the direct evaluation of models and radiographs. Initial treatment plans arise after an assessment has taken place and may not explicitly rely on both types of records. Comprehensive evaluations may suggest a broader assessment that includes models and X-rays but does not emphasize them as a primary focus in the same way that diagnostic records do.
