This book presents useful tips and strategies on how to integrate aligner orthodontics successfully into clinical practice, whether outsourced or with in-office aligner treatment. This second edition sees the authors review the diagnostic protocols and the biomechanics of aligners before presenting aligner orthodontics protocols. Supported by accompanying case documentation, the discussion of each malocclusion includes information on the associated symptoms, the rationale behind the selected treatment approaches, and the various outcomes achieved. The separation into sections on each malocclusion helps patients and clinicians in deciding whether this system can provide optimal treatment outcomes for a particular clinical situation. This is a practical manual for any clinician interested in the treatment modality of aligner orthodontics.
