Обзор

This study aims to evaluate the effectiveness of auxiliary segmental lingual appliances in leveling the Curve of Wilson at the second molars in patients undergoing labial fixed orthodontic treatment. Patients exhibiting an excessive (deep) Curve of Wilson at the second molar bilaterally (meaning lingually inclined mandibular second molar) will be recruited.. Using a split-mouth design, one side will receive the intervention (auxiliary segmental lingual appliances), while the other side will serve as the control. The 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. Measurements will be taken on digital impressions at baseline (T0), after leveling with a stainless steel labial archwire (T1), and three months after applying the auxiliary segmental lingual appliances. The effectiveness will be assessed by comparing the two groups.

Подробное описание

This study focuses on evaluating the effectiveness of auxiliary segmental lingual appliances in leveling the Curve of Wilson at the second molars in patients undergoing labial fixed orthodontic treatment. The study will recruit patients who exhibit an excessive (deep) Curve of Wilson at the second molar bilaterally (meaning lingually inclined mandibular second molar). A split-mouth design will be employed, where one side of the mouth will receive the intervention (auxiliary segmental lingual appliances), and the other side will serve as the control.

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.

Вмешательства

Процедура 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.
