Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The primary variables measured include the Curve of Wilson at the second and first molars, and the distance from the mesiolingual and distolingual cusps of the second molar to the occlusal plane of the first molar. These measurements will be taken using digital impressions at three different time points: baseline (T0), after leveling with a stainless steel labial archwire (T1), and three months after the application of the auxiliary segmental lingual appliances.
The study aims to compare the effectiveness of the auxiliary segmental lingual appliances by analyzing the differences between the intervention and control sides. This comparison will help determine the impact of the appliances on achieving a more balanced and functional occlusal plane, potentially improving orthodontic treatment outcomes for patients with malocclusion issues.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Auxiliary Segmental Lingual Appliances Intervention in One Side
In this arm, patients will receive the intervention of auxiliary segmental lingual appliances on one side of the mouth. The intervention aims to level the Curve of Wilson by adjusting the lingual inclination and leveling the lingual cusps of the mandibular second molar.
Auxiliary Segmental Lingual Appliances
This intervention involves the use of auxiliary segmental lingual appliances specifically designed to level the Curve of Wilson at the second molars in patients undergoing labial fixed orthodontic treatment. The primary goal is to adjust the lingual inclination of the mandibular second molar, thereby achieving a more balanced and functional occlusal plane.
Control in Another Side
In this arm, patients will not receive the intervention of auxiliary segmental lingual appliances on another side of the mouth.
No interventions assigned to this group
