Expansion and Periodontal Concerns in Adults

Transverse expansion of the maxilla in adults is feasible because the dental- alveolar complex is displaced (rather than only the teeth) by using the Haas expander. The expander is turned slowly no more than one turn every other day in patients in their 20’s and every third to fifth day in older patients. Data will be presented showing the expansion is equivalent to that seen in children, is stable long-term, and there is no opening rotation of the mandible. Measures of the clinical crown heights of the posterior teeth indicate there is minimal gingival recession seen only in females and of little clinical relevance. Also presented will be cases and data of maxillary and mandibular expansion in adults to correct arch constriction and crowding.

Learning Objectives:

  • Distinguish the difference between child and adult expansion in terms of how the expansion is achieved
  • Describe the difference in the rate of activation of the expansion screw in children, young adults and older adults
  • Discuss whether clinically relevant gingival recession occurs in adults undergoing maxillary expansion with a Haas expander

Clinical and Biologic Considerations on MARPE (Mini-screw Assisted Rapid Palatal Expansion)

Attendees of this lecture will learn how to manage transverse problems with MARPE (miniscrew assisted rapid palatal expansion).

Learning Objectives:

  • Relate the biologic and biomechanical background of MARPE
  • Evaluate clinical application and changes after MARPE
  • Compare MARPE with SARPE
