NCT01952301

Brief Summary

A split-mouth study comparing soft tissue augmentation results using free gingival graft (FGG) versus xenogeneic collagen matrix (CM) for the generation of keratinized tissue (KT) around teeth with insufficient (\< 2mm) KT.

Eligibility Criteria

Age8 Years - 70 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • At least two non-adjacent teeth in contralateral quadrants of the same jaw with \< 2mm of KT that requires soft tissue grafting (1-4 teeth may be treated). In case of adjacent teeth requiring grafting, only one tooth at each site will act as test or control tooth, but all teeth will get the same treatment). The number of teeth treated must be the same on the test and control sites.
  • Root coverage is not desired at the time of grafting.
  • Females of childbearing potential must have a documented negative urine pregnancy test.
  • Read, understood and signed an institutional review board (IRB) approved Informed Consent Form (ICF).
  • Able and willing to follow study procedures and instructions.
  • Multi-rooted teeth may be treated but will not be included as study teeth

You may not qualify if:

  • Vestibule depth of less than 7mm from base of recession, and/or teeth with Miller Grade 2 or higher mobility.
  • Any systemic conditions (i.e., diabetes mellitus, cancer, HIV, bone metabolic diseases) that could compromise wound healing and/ or preclude periodontal surgery; or who are currently receiving or have received within two months prior to study entry, systemic corticosteroids, immunosuppressive agents, radiation therapy, and/or chemotherapy which could compromise wound healing and preclude periodontal surgery.
  • Presence of acute infectious lesions in the areas intended for surgery.
  • History of any tobacco use within the last six months.
  • Taking intramuscular or intravenous bisphosphonates.
  • Known hypersensitivity to collagen products, and/or allergy to iodine or shellfish.
  • Participating in other clinical studies involving therapeutic intervention (either medical or dental).
  • Previously undergone a gingival grafting procedure on the test or control teeth or the teeth adjacent to the study site.
  • Female subjects who are pregnant or lactating, or who intend to become pregnant during the study duration following entrance into the study.
  • Subjects, who in the opinion of the investigator, for any reason other than those listed above, will not be able to complete the study per protocol.
