Aetiology of gingival recession and orthodontics
Caution: Some images may be suitable for practitioners only
Wennstrom(1987) suggested thickness may be a more important
dimension to concern orthodontists and periodontists than
the width of the keratinised tissue
Orthodontic movement beyond the basal bone limits greatly increases the
recession risk
Increased by non-extraction, arch expansion techniques
Consider limits of non-surgical treatment- especially careful evaluation of
borderline cases (Handleman 1996)

Poor oral hygiene,
Periodontal inflammation
