Pilot Study for Healing and Safety Outcomes in Gingival Recession

Phase 4
Completed
Conditions
Gingival Recession
Interventions
Biological: AlloDerm
Biological: Markman Biologics Microsurfaced ADM
Registration Number
NCT04614350
Lead Sponsor
McGuire Institute
Brief Summary

Prospective, randomized, within subjects-controlled design

Detailed Description

The objective of this trial is to evaluate clinical healing outcomes of microsurfaced cadaveric ADM (Markman Biologics) used in sites with \< 1 mm of attached gingiva requiring soft tissue grafting without root coverage as compared to control cadaveric ADM (AlloDerm, LifeCell) over 180-day post-op period. During the treatment period, each site will be monitored for soft tissue healing and augmentation of keratinized tissue width. All subjects will be seen at post-op day 7, 14, 30, 90, and 180.

Recruitment & Eligibility

Status
COMPLETED
Sex
All
Target Recruitment
10
Inclusion Criteria
  1. Signed informed consent by patient or Legally Authorized Representative (LAR)
  2. Patients with ≥2 non-adjacent teeth in the same jaw presenting with ≤ 1mm attached gingiva that requires soft tissue grafting without the need for root coverage
  3. Patients with good oral hygiene as indicated by presence of minimal plaque and absence of material alba and calculus.
  4. ≥ 18 and ≤ 75 years of age
  5. Sexually active subjects (both men and women) who agree to use acceptable contraceptive methods for the duration of the study.
Exclusion Criteria
  1. Vestibule depth <7mm from the base of recession
  2. Systemic condition, such as uncontrolled diabetes mellitus, HIV, cancer, or bone metabolic disease that could compromise wound healing
  3. Treatment with systemic corticosteroids, immunosuppressive agents, radiation therapy, or chemotherapy within 2 months of enrollment in the study
  4. Acute infection lesions in intended grafting sites
  5. Received intravenous or intramuscular bisphosphonates
  6. Tobacco use within 3 months of enrollment or for the duration of the study
  7. Only molar teeth suitable for soft tissue grafting (molars may be treated but not assigned as the study tooth)
  8. Miller grade ≥2 mobility on grafting sites or adjacent teeth
  9. Known hypersensitivity to bovine collagen or iodine (shellfish allergy)
  10. Previous treatment with an advanced biologic at sites selected fro grafting or the adjacent teeth
  11. Pregnant or nursing female subjects; women of child-bearing potential must have a negative urine pregnancy test.
  12. Developmental disability/significant psychological disorder that in the opinion of the investigator could impair the subject's ability to provide informed consent, participate in the study protocol or record study measures, including untreated schizophrenia, bipolar disorder and psychiatric hospitalization within the last 2 years.
  13. Active alcohol or substance abuse (including marijuana, THC, CBD oils and products) in the opinion of the investigator that could impair the subject's participation in the study.
  14. Any medical condition or co-morbidity that in the opinion of the investigator, would prevent successful participation in the study
  15. Known allergies to Cefoxitin, Gentamycin, Lincomycin, Polymyxin B, Vancomycin, or any antibiotic in these same classes.
  16. Known allergy to Polysorbate 20

graft texture assessed as smooth, stippled, rolled, or other and as more firm, equally firm, less firm

To compare graft healing at post-op day 14 between Markman Biologics Microsurfaced ADM (Active) and AlloDerm ADM (Control) as assessed by inflammationDay 14 post op

tissue inflammation using a score of 0 (normal) to 4 (severe)

Secondary Outcome Measures
NameTimeMethod
Assessment of Infection through 180 days180 days

infection assesse by redness, swelling, pus, fevers, chills

Subject Discomfortthrough 180 days

Subject discomfort will be assessed using a single questionnaire containing questions on pain and the need for anti-inflammatory and/or pain meds.
