title: [Papilla-preserving flap procedure in periodontal implantation of alloplastic materials. Comparative study].
abstract: 40 periodontal defects with probing depths of 5 mm in 10 patients were treated with a conventional flap or with the "papilla preservation flap". In addition, half of the defects received granular hydroxyapatite. In terms of pocket depth and probing attachment-level no significant differences were seen between the 4 groups after 3 and 6 months. Regarding the development of gingival recession, however, the papilla preservation technique has significant advantages and showed better aesthetic results.
