This document discusses treatment planning in orthodontics. It begins by defining treatment planning and outlining its goals, which include achieving functional occlusion, jaw function, and aesthetics. It then describes the logical sequence of treatment planning, which involves prioritizing problems, considering treatment possibilities, evaluating interactions, and developing alternative plans while considering risks and costs. Key aspects of treatment planning discussed include pathological versus developmental problems, setting treatment priorities, evaluating treatment possibilities, compromising when goals cannot all be fully achieved, and the importance of timing treatment appropriately based on a patient's age. The document also outlines principles of orthodontic triage and maximizing esthetic outcomes at both the macro and micro levels.
