Controversy over the role of orthodontics as cause of recession

If the tooth is within the envelope of the alveolar process will not undergo recession Wennstrom 1996

Investigation of periodontal change long term with bonded retainers Renkema 2013

  • 300 patients assessed prior to treatment – 5 years post treatment with bonded retainers
  • Trends observed
    • Greater recession defects with time
      1. 1st premolar / cuspid most effected tooth:14%
      2. Upper left canine: 11%
      3. Lower right central incisor: 10%

Do orthodontic patients experience more recession then untreated patients

  • Renkema 2013
    • 120 untreated patients – no malocclusion, 9 year follow up
    • OR 4.5 (2.6-7.7) statistically significant difference –
    • Greater recession in treated Vs untreated
  • Gebistorf 2018
    • Untreated patients with malocclusion
    • Greater recession in untreated Vs treated

 

Factors effect gingival recession Joss- Vassalli 2010

  • Lower incisor proclination
  • Width of gingiva
  • Thickness of attached gingiva
  • Oral hygiene
  • Thickness of symphasis
  • = No CORRELATION TO RECESSION

 

Ongoing prospective study with control to investigate factors

  • Preliminary 1 year debond – orthodontic movement does not appear to be factor
