Adjunctive Applications of Clear Aligner Orthodontic Therapy in Periodontal Plastic Surgery & Implant Therapy

Homa H. Zadeh, DDS, PhD

Course Description

Inflammatory periodontitis results in many negative sequalae, including marginal bone loss, gingival recession, interdental tissue loss, pathologic migration of teeth. Periodontal therapy is design to arrest the progression of attachment loss. Regenerative periodontal therapy can go one step further, seeking to restore some of the lost components of the periodontal attachment apparatus.

However, periodontal therapy alone is not adequate to restore optimal esthetics and function. Adjunctive orthodontic therapy is quite useful to reposition teeth, which have drifted as a result of pathologic migration. Moreover, tooth position can potentially predispose to attachment loss. For example, crowding and facially positioned roots are examples of potential predisposing factors to attachment loss and gingival recession. Treatment of recession defects is not as effective when teeth are positioned outside of the alveolar bone. Orthodontic therapy and optimize tooth position within the alveolar bone to improve the chances of root coverage periodontal surgery.
Implants are often needed in situations where adjacent teeth have drifted and in poor position. Orthodontic therapy can improve spacing of teeth to optimize implant positioning.
Multiple clinical trials and systematic reviews have demonstrated better periodontal parameters of clear aligner orthodontic therapy, compared with conventional fixed orthodontic appliances.

Recent improvements of digital tools, have provided advantages of clear aligner therapy to reposition teeth. In particular, root torqueing aims to reposition cervical regions of roots back within the alveolar housing. Interproximal reduction can reduce the size of embrasure spaces to improve the esthetics of “black triangles” without restoration. Drifted teeth can be repositioned to open spaces which were not optimal for implant positioning.

This course will review the adjunctive value of clear aligner therapy to enhance the esthetic and functional outcomes of periodontal plastic surgery, as well as optimize teeth position in preparation for implant therapy.

Educational Format

This course offers a flexible educational format to accommodate all clinicians’ needs and interests.

Participation may take place either:

  • In-person or remotely (held over Zoom)
  • Live (synchronous) or on-demand (asynchronous)

The hybrid education model provides some of the information in an online format, so that prior to the live presentations, participants have an opportunity to review the content and gain basic background information. This information is accessible on an on-demand basis.
