The assertion that the treatment plan should aim for canine guidance and functional occlusion is indeed accurate. Canine guidance refers to the functional relationship where the canines contact during lateral movements of the jaw, allowing the other teeth to disclude. This is a desirable occlusal scheme because it helps to protect posterior teeth and promote efficient movement in function, which is important for overall dental health and stability.

Functional occlusion encompasses a wider range of considerations, ensuring that all teeth contact properly during functional activities such as chewing. This balance is essential in preventing undue stress on the teeth and supporting structures, which can lead to various dental issues over time. By focusing on both canine guidance and functional occlusion in the treatment plan, orthodontic treatment not only addresses aesthetic concerns but also prioritizes the long-term functional health of the patient's occlusion.

Thus, this approach contributes to a comprehensive orthodontic strategy that improves both the appearance and functionality of the bite, fostering greater patient satisfaction and health post-treatment.
