Final answer:
Pre-vs.-post ortho pics are used to show the changes that occur before and after orthodontic treatment. They are an essential tool in orthodontics to demonstrate the effectiveness of braces or aligner therapy.
Step-by-step explanation:
In orthodontics, pre-vs.-post ortho pics are used to show the changes that occur before and after orthodontic treatment. These pictures are taken as part of the dental records to track the progress and outcomes of braces or aligner therapy.Pre-ortho pics are taken before the treatment begins and are used to assess the initial alignment of the teeth, jaw relationships, and any pre-existing conditions. Post-ortho pics are taken after the treatment is complete to compare the results with the initial condition and evaluate the success of the treatment.By comparing the pre-ortho and post-ortho pics, orthodontists can identify the specific changes that occurred during the treatment, such as teeth alignment, jaw positioning, and overall improvement in the bite and smile. These pictures are an essential tool in orthodontics to demonstrate the effectiveness of orthodontic treatment.
