NCT03003819

Brief Summary

A prospective RCT of intact extractions with delayed implant placement comparing extraction socket management effectiveness and office economics of two collagen matrices. Soft tissue wound healing will be assessed out to 4-months post-operative, when implants will be placed.

Study Arms (2)

Control Collagen Wound Dressing

ACTIVE COMPARATOR

Bovine collagen sponge used to control bleeding, stabilize blood clots and protect dental wounds

Device: Control Collagen Wound Dressing

Test Collagen Matrix

ACTIVE COMPARATOR

Bilayer, porcine collagen matrix for soft tissue regeneration used as a socket seal in extraction socket grafting

Device: Test Collagen Matrix

Interventions

Following resolution of any periodontal issues in the region of study and administration of pre-surgical antibiotic and local anesthetic, minimally traumatic extraction will be performed with periotomes . After degranulation and bone graft placement, control or test biomaterial will be placed according to the randomization schedule and surgical instructions for each biomaterial.

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subject indicated for anterior tooth extraction (from premolars forward) intended for implant placement.
  • Subjects with essentially intact extraction sockets - bony dehiscences \< 1/3 the depth of socket and mesial-distal width of tooth socket
  • Subjects will have read, understood and signed an institutional review board (IRB) approved Informed Consent Form (ICF).
  • Subjects must be able and willing to follow study procedures and instructions

You may not qualify if:

  • Subjects with healing disorders (i.e., diabetes mellitus, cancer, HIV, bone metabolic diseases) that could compromise wound healing and/ or preclude implant 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.
  • Subjects taking intramuscular or intravenous bisphosphonates.
  • Subjects who have a known allergy or sensitivity to collagen.
  • Heavy smokers/tobacco users defined as those smoking ≥ 10 cigarettes or ≥ 4 cigars or ≥ 4 pipes per day. For non-heavy smokers, smoking ≥ 10 cigarettes or ≥ 4 cigars or ≥ 4 pipes per day is prohibited for the duration of the study.
  • Female subjects who are pregnant or lactating, or who intend to become pregnant during the study duration
  • Subjects participating in other clinical studies involving therapeutic intervention (either medical or dental).
  • 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.
