Establishing well-defined treatment goals in the field of Orthodontics is imperative to enhance diagnostic precision and mitigate the potential for treatment failure. The occurrence of treatment failures is often associated with inadequate patient cooperation or incorrect wire/brace selection, which can be attributed to misdiagnosis.

An unsuccessful orthodontic outcome can manifest in various forms, including TMJ symptoms, instability, tooth wear, periodontal deterioration, or facial asymmetry. Among the contributing factors, condylar displacement emerges as a significant cause of unstable results. Condylar displacement refers to the dislocation of the condyle from its natural position within the fossa when the patient occludes their teeth. This leads to a host of problems that may manifest at different time intervals but are, unfortunately, inevitable. As the esteemed Dr. Roth used to assert, the "fruits of orthodontic labour" become evident approximately a decade after the completion of treatment. Any alteration in the temporomandibular joints directly impacts the occlusal relationship between the upper and lower teeth, underscoring the paramount importance of achieving a correct mandibular position and condyle-fossa relationship as one of the five fundamental treatment goals.

Dr. Roth advocated for establishing goals across all areas influenced by orthodontic treatment, which can be broadly categorized into the following five domains:

• Facial Esthetic
• Dental Esthetics
• Functional Occlusion
• Periodontal Health
• Healthy TMJ (Correct Condylar-Fossa Relationship)

The significance of condylar position as a treatment goal cannot be overstated. To reiterate, our objective is to ensure simultaneous contact of the teeth when the condyle is properly seated in an anterior superior position on the transversely cantered disc. As the jaw opens, the condyles and discs move in unison downward from their uppermost position within the fossae.

Complete or partial disc displacement triggers degenerative changes in the disc, condyle, and fossa. This alteration in the condyle's movement, coupled with changes in jaw position, ultimately leads to unfavourable changes in the facial profile, such as mandibular retrognathism and open bite.
