the purpose of this study was to compare the effects on the periodontium of two of the more commonly used surgical techniques for labially impacted canines -- ( 1 ) exposure of the entire labial aspect of the anatomic crown with total excision of all keratinized tissue ( the window approach ) and ( 2 ) a technique which exposes only 4 to 5 mm of the most superficial portion of the labial aspect of the cusp tip while maintaining 2 to 3 mm of keratinized tissue .
