Brief Summary

In a recent meta-analysis, Graziani et al. reported that despite the "ideal" treatment for multiple gingival recession defects is not yet identified, there are some indirect suggestions from the analyzed data that, in comparison to the traditional coronally advanced flap (CAF) approach, the use of additional grafting, modifications of the flap technique or tunnel variation with connective tissue graft (CTG) may improve clinical results. Furthermore, various allografts or replacement biomaterials have been developed instead of a connective tissue graft in order to reduce patient morbidity. A newly developed porcine-derived bio-resorbable collagen matrix (CM) (Fibro-Gide) has been recently introduced as an alternative to CTG in periodontal plastic surgery. The aim of this study will be to compare the outcomes of two muco-gingival surgery techniques, the modified coronali advanced flap (MCAF) for multiple recession defects and the modified coronally advanced tunnel technique (MCAT), performed in the Department of Periodontology of San Raffaele Hospital with the results reported in the literature. Secondarily, the study will evaluate whether patients report a preference in terms of discomfort and perception of aesthetics between the two surgical techniques.

Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • multiple (i.e., at least 2) Miller Class I and/or II gingival recessions located in the maxillary, with an apico-coronal extension (i.e., defect depth \> 1 mm with at least one defect \> 2 mm) and with at least 1 mm of residual keratinized tissue,
  • good general health, with no systemic diseases that could influence the outcome of the therapy,
  • healthy periodontal conditions (i.e., no presence of sites ≥ 4 mm and/or presence of intra-bony defects in the selected sites),
  • adequate oral hygiene (full mouth plaque score (FMPS) of \<25% at baseline (following initial oral hygiene instructions and prophylaxis),
  • an adequate control of inflammation (full mouth bleeding score \[FMBS\]) of \<25% at baseline (following initial oral hygiene instructions and prophylaxis).

You may not qualify if:

  • subjects who currently smoke \>10 cigarettes/day,
  • female subjects who are nursing, pregnant, or plan to become pregnant,
  • contraindication against oral surgical interventions,
  • contraindication against use of Fibro-Gide (acute infection in the area of surgery and patient with collagen allergy)
