Orthodontic tooth movement requires skillful management of the periodontium and, oftentimes, there are situations that require the direct intervention of the periodontist. Conversely, the resolution of periodontal problems can often be facilitated with orthodontics. This lecture will discuss the interactions between orthodontists and periodontists, and how important communication is among all dentists providing care for interdisciplinary patients, illustrating all the major topics with clinical cases.

Orthodontic movement involves significant changes in tooth supporting structures. Hence, dentoalveolar tissue management becomes critical in patients who are highly prone to periodontal tissue breakdown and necessitate close collaboration between orthodontist and periodontist.

Multidisciplinary therapy has been a concept in dentistry for the past years, and there is an intimate biological relationship between orthodontics and periodontics. Orthodontics has significantly impacted the field of periodontics and prosthetics. The objective of this type of tooth movement is to level and modify hard and soft tissue morphology, create biological optimal inter-root and "root to implant" relationships.
