Ridge Augmentation Without Primary Closure

December 6, 2016 updated by: Henry Greenwell, University of Louisville

Ridge Augmentation Comparing the Clinical and Histologic Healing of a Cancellous Block Allograft Plus a Barrier Membrane With and Without Primary Closure

This study is designed to compare the clinical and histologic results of ridge augmentation with and without primary closure over the barrier membrane. The hypothesis is that there will be no difference in crestal ridge width between the two groups.

Study Overview

Detailed Description

A maximum of 30 patients will be selected that meet the following criteria:

Inclusion Criteria

  1. At least a one tooth area with a ridge defect, treatment planned to receive a dental implant. The site must be bordered by at least one tooth.
  2. Healthy person that is at least 18 years old.
  3. Patient understands and signs an informed consent approved by the University of Louisville Human Studies Committee.

Exclusion Criteria

  1. Patients with debilitating systemic diseases, diseases that affect the periodontium, or psychological problems that would interfere with treatment.
  2. Previous head and neck radiation or chemotherapy within the previous 12 months.
  3. Patients with known allergy to any of the materials that will be used in the study.
  4. Smokers.
  5. Patients who need prophylactic antibiotics prior to dental procedures.
  6. Patients on long-term steroid therapy or oral bisphosphonates > 3 years or any IV biosphosphonates.
  7. Patients who are pregnant.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: With primary closure
The ridge augmentation graft will be covered with a barrier membrane and the soft tissue will be primarily closed.
A cancellous block allograft will be placed for ridge augmentation and covered with a barrier membrane. The soft tissue will be primarily closed over the membrane.
Other Names:
  • Primary soft tissue closure over the membrane.
Experimental: Without primary closure
The ridge augmentation graft will be covered with a barrier membrane and the soft tissue will not be primarily closed.
A cancellous block allograft will be placed for ridge augmentation and covered with a barrier membrane. The soft tissue will not be primarily closed over the membrane.
Other Names:
  • No primary soft tissue closure over the membrane.
