Brief Summary: Comparative Management of Skeletal Anterior Open Bite Using Mini-Screw Supported Intrusion with Clear Aligners Versus Fixed Appliances

PICO elements

Population: Adults (17-25 years) with uncompensated skeletal anterior open bite.

Intervention: TAD-supported intrusion with clear aligners. Comparison: TAD-supported intrusion with fixed appliances.

Outcomes:

Primary: Anterior open bite closure. Secondary: Molar intrusion, mandibular autorotation, incisor movement and quality of life.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The aim of the study is to compare the effects of mini-screw supported maxillary posterior segments' intrusion using fixed appliances versus clear aligners.
