The duration of orthodontic treatment in class III patients is mainly influenced by factors related to patient compliance. Patients who missed more appointments did not show a worse orthodontic finish, but rather a longer treatment. No occlusal, cephalometric, or demographic variable obtained before treatment could provide a significant prediction of treatment time in class III patients. After nine years in the United States Army Dental Corps, he returned to his hometown of Redmond, Washington, and bought the office where he had orthodontic appliances as a teenager.
Another factor related to class III treatment is that severe anterior crossbite is usually related to substantial and obvious skeletal discrepancies, which require surgical treatment3, unlike class II patients, whose skeletal discrepancies are more “aesthetically acceptable” 1.5 and can be treated compensatory. It is not enough to classify orthodontic malocclusions based solely on the classification of the teeth. It's often difficult class III malocclusions that challenge orthodontists to think creatively and progressively. Therefore, knowing the factors that contribute to treatment over time can help orthodontists to control some of these variables and to perform a more effective treatment for class III malocclusion, to have a more fluid relationship with patients and to achieve greater success in practice.
The passive self-ligature treatment approach, together with the first lightweight elastics and tongue trainers, resulted in a class I occlusion with better smile aesthetics and greater visualization of teeth at rest and in animation. Class II problems are treated by redirecting growth to harmonize upper teeth, lower teeth, and jaws. Therefore, our objective is to evaluate the variables present in orthodontic intervention for class III malocclusion that could influence the duration of treatment. In all cases, and especially in difficult class III cases, patient education is of utmost importance to achieve a high degree of patient compliance with intraoral elastic wear, oral hygiene and bite compression exercises, which work together to correct multiple problems simultaneously.
In addition, the class III growth pattern has some peculiarities compared to class I and class II patients, since a more vertical pattern and a longer growth peak in class III patients than in class III patients. The initial position of the upper and lower anterior teeth and mandibular growth are not favorable to non-surgical treatment. 13,28. This may occur because it is known that moderate to severe class III malocclusions can have a significant impact on aesthetics and the quality of life for the patient., keeping them more motivated and easier to manage.
