Abstract

Unilateral posterior crossbite case is quite complicated and difficult for orthodontist. The etiology may include any combination of dental, skeletal and neuromuscular functional components. This case is a 23 years old female with severe class II skeletal pattern and right side posterior teeth complete buccal crossbite. With the aid of TADs (temporary anchorage device) and full coverage biting plate, unilateral posterior buccal crossbite was corrected in an efficient way. Without an orthognathic surgery, the results of good dentition control in vertical direction and large amount of overjet reduction can still be obtained.
