This is a prospective, multi-center study to evaluate the use of CopiOs Pericardium Membrane, a bovine xenograft, with use of Puros Cancellous Particulate Allograft, for the augmentation of localized alveolar ridge defects on either the maxilla or mandible.

Condition Intervention
Alveolar Ridge Defect
Device: CopiOs Pericardium Membrane

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Prospective, Multi-Center Study of CopiOs® Pericardium Membrane With Puros® Cancellous Particulate Allograft for Localized Alveolar Ridge Augmentation

Further study details as provided by Zimmer Biomet:

Primary Outcome Measures:
  • Change in Horizontal Ridge Widths From Baseline to 6 Months [ Time Frame: 6 months ]
    The primary outcome measure of the study was the average change in ridge width from baseline (pre operative/pre grafting) to 6 months post surgery. The ridge measurements were taken using ridge mapping calipers and recorded for each patient at baseline and 6 months. Baseline measurements were taken at the site of greatest ridge width deficiency as determined by the investigator and repeated at the same location for subsequent measurements. A radiographic template with a radiopaque foil was utilized to standardize clinical and radiographic measurements for each patient.

Secondary Outcome Measures:
  • Mean Wound Healing Index at 6 Months [ Time Frame: 6 months ]

    Score Description

    1. Uneventful wound healing with no gingival edema, erythema, suppuration, patient discomfort or flap dehiscence
    2. Uneventful wound healing with slight gingival edema, erythema, patient discomfort or flap dehiscence but no suppuration
    3. Poor wound healing with significant gingival edema, erythema, patient discomfort or flap dehiscence with suppuration

Enrollment: 51
Study Start Date: June 2009
Study Completion Date: December 2011
Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: CopiOs Pericardium Membrane
Subject's study site must exhibit a partially edentulous ridge of the maxilla or mandible with at least one tooth-span in length and less than 5.5mm in its smallest buccolingual dimension as measured by ridge-mapping calipers.
Device: CopiOs Pericardium Membrane
CopiOs Pericardium, Puros Cancellous
Other Names:
  • Pericardium Membrane
  • Bovine Xenograft
  • Cancellous Particulate
  • Human Allograft

Detailed Description:
The study will evaluate the use of CopiOs Pericardium Membrane (CopiOs Pericardium), a bovine xenograft, with the use of Puros Cancellous Particulate Allograft (Puros Cancellous), a mineralized allograft, for the augmentation of localized alveolar ridge defects in edentulous sites. The purpose of the study will be to determine placement time, ease of use, stability, esthetics and to clinically evaluate the efficacy of the list products. A biopsy will be taken from a subset of the patient population, at one investigational site, to evaluate the grafted site's formation of new bone. The study hypothesis is that if CopiOs Pericardium and Puros Cancellous are used, the a single, localized alveolar ridge defect will clinically improve at an edentulous site.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Male or female, of any ethnicity, between 18 and 99 years of age
  • Health status of P1(ASA I) or P2 (ASA II), as classified by the American Academy of Anesthesiologists
  • Able to communicate with the investigator and read, understand, and sign the informed consent form
  • No evidence of active moderate or severe periodontitis
  • Must be available for multiple follow-up visits for the duration of the study
  • The study site must exhibit a partially edentulous ridge of the maxilla or mandible with at least one tooth-span in length and less than 5.5 mm in its smallest buccolingual dimension as measured by ridge-mapping calipers (#RIDGE-CALIPER, Salvin Dental Specialties, Inc., Charlotte, NC).

Exclusion Criteria:

  • Inability or failure to maintain adequate oral hygiene
  • Women who are bread-feeding, pregnant, or who intend to become pregnant during this study period. Women of childbearing potential should be practicing a medically accepted method of birth control
  • Patients with unstable systemic diseases
  • Patients with compromised immune system (e.g. uncontrolled diabetes, etc.) or unstable bleeding disorder
  • Patients with active infectious diseases (e.g. hepatitis, tuberculosis, HEV, etc.)
  • Patients with a mental disability that may hinder participation in the study (e.g. inability to follow through with oral hygiene instructions, postoperative instructions, follow-up commitments, etc.)
  • Patients taking steroid medications or undergoing other immunosuppressive therapy
  • Radiation, cancer therapy, and/or radiation specifically at the oral cavity within the last 6 months
  • History of previous ridge augmentation at the site of interest
  • Augmentation sites with localized pathology
  • Patient who has participated in a clinical trial within 30 days of being enrolled in this study, is currently enrolled in another study, or plans to enroll in another study before the completion of of this study.
  • Unresolved oral pathologies (e.g. periodontal disease, caries, etc.)
  • Medications or conditions contraindicated for bone regeneration: methotrexate, corticosteroids, history of bisphosphonate use, cyclosporine-A, etc.
  • Patients who have more than a minimal tobacco use (e.g. >10 cigarettes per day)
  • Other conditions the investigator may feel would inhibit the patient from being a good candidate for this study or which are contraindicated in the Directions for Use.
  • Note: Careful consideration should be given to alternative therapies prior to performing bone grafting in patients who have severe endocrine-induced bone diseases (e.g.hyperparathyroidism), or who are undergoing current therapy with drugs that intervene in calcium metabolism.
