3D Image-Aided Diagnosis and Treatment of Impacted and Transposed Teeth

This chapter provides insights into evidence-based use of cone beam computed tomography (CBCT) for treating impacted and transposed teeth and how best to utilize the information thus derived for predictable and efficient treatment of these teeth. Specifically, it provides the foundational background on impacted and transposed teeth and extends this to contemporary insights gained by imaging these teeth with CBCT. The chapter then discusses protocols for CBCT imaging, interpretation, and treatment planning for impacted and transposed teeth. Finally, it uses cases to demonstrate the potential pitfalls of suboptimal diagnosis and treatments resulting partially from the limitations of two-dimensional (2D) radiographs and to demonstrate approaches for individualized three-dimensional (3D) image-based biomechanics for efficient and predictable treatment of impacted and transposed teeth while minimizing damage to neighboring roots or periodontium.
