Clear Aligner Technique is intended to be a clinical handbook. When a clinician plans to treat a particular case with clear aligners, it is my hope that he or she will refer to the chapter pertinent to the malocclusion present and, based on the information there, be able to (1) arrive at a proper diagnosis, (2) program in a suitable treatment plan, (3) design the digital tooth movements to match the treatment goals, and (4) execute the treatment clinically, troubleshooting when complications arise and applying techniques to finish the case to a standard of excellence.

The future is clear!

Clear Aligner Technique Book Cover

Synopsis by Quintessence Publishing

Clear aligners are the future of orthodontics, but digital orthodontics evolves so rapidly that it is hard to keep pace. This book approaches clear aligner treatment from a diagnosis and treatment-planning perspective, discussing time-tested orthodontic principles like biomechanics and anchorage and demonstrating how to apply them to orthodontic cases using these appliances. Each chapter explains how to use clear aligners to treat a given malocclusion and teaches clinicians how to program a suitable treatment plan using available software, how to design the digital tooth movements to match the treatment goals, and finally how to execute the treatment clinically and finish the case well. This clinical handbook will prepare orthodontists and dental students to exceed patient expectations with the most esthetic orthodontic appliance currently available.

This textbook is a must-have reference for the dentist or orthodontist who performs clear aligner treatment in his or her practice.
