Study summary

There are some orthodontics treatments that perform risk movements ,and a bone dehiscence may be expected. In that cases mucogingival surgery , such as connective tissue grafts, is necessary prior to tooth movement.

The connective tissue graft in combination with coronal advanced flap is still considered the gold standard , although the use of porcine collagen matrix has obtained promising results for treatment of Miller class I and II recession defects.

Most of the studies report clinical results after a connective tissue graft and there is no evidence about the type of attachment obtained after the graft is performed, a few articles have shown histological results. But, as a rule , a histological study is only performed under exceptional circumstances such as a dental fracture, untreatable decay, tooth extraction for orthodontic reasons, or other reasons.

Most of the techniques results in the formation of a long junctional epithelium and connective tissue attachment with fibers parallel to the root surface. Animals studies have shown a shorter epithelium and a larger new cementum formation after the use of the collagen matrix.

Read the detailed description

The purpose of this study is to confirm that periodontal regeneration happens after mucogingival surgery The principal outcome is compare the millimeters of new attachment create after a connective tissue graft and after the use of a porcine collagen matrix in teeth that have to been extracted (because of the orthodontic planing treatment) after mucogingival surgery .

The secondary outcomes are:

  1. length of new cementum (histometry results)
  2. length of the junctional epithelium (histometry results)
  3. length of connective tissue attachment (histometry results)
  4. complete root coverage (clinical results)
  5. width of keratinized tissue
