A Feasibility Study for Growth Bone Vertically With Titanium Mesh and Allograft in Lower Posterior Jaw

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02255149
Recruitment Status : Completed
First Posted : October 2, 2014

Brief Summary:

This study will involve placing donor bone into the back of lower jaw then covering with a newly designed titanium mesh. The mesh will then stay in the mouth for 4 months before it will be removed. Implants will be placed in the newly formed bone.

The goal of this study is to test how well using a newly designed titanium mesh and bone particles can grow bone in the back of the lower jaw. The investigators are also checking if the newly formed bone will stay around implants that will have been in use for 12 months.

Condition or disease Intervention/treatment Phase
Alveolar Bone Loss Device: Bone/Mesh Not Applicable

Detailed Description:

Inclusion Criteria

  • Patients are at least 18 years old
  • At least two adjacent back teeth in the lower jaw are missing
  • No medical contraindication to dental surgery
  • Inadequate vertical ridge height at edentulous region (less than 10mm)

Exclusion Criteria

  • Unstable systemic diseases or conditions that would compromise the healing potential
  • Patients with osseous metabolic disorders (e.g., osteoporosis, Paget's disease etc.)
  • Patients who are pregnant or expect to get pregnant
  • Patients with unstable dental disease (e.g. caries and periodontitis) in the surgical sextant

Official Title: Vertical Ridge Augmentation Using Titanium Mesh and Allograft in Posterior Mandible: A Feasibility Study
Study Start Date : September 2011
Actual Primary Completion Date : November 2014
Actual Study Completion Date : November 2014

Arm Intervention/treatment
Experimental: Bone/Mesh
Allograft and Titanium mesh will be used to grow jaw bone vertically.
Device: Bone/Mesh
A titanium mesh (Ti-Mesh) that is more porous than other materials will be placed in order to hold a spot for the bone particles to grow.

Primary Outcome Measures :
  1. Bone Height [ Time Frame: 5 months ]
    Diameter of the bone measured from the alveolar crest to the inferior alveolar nerve after the grafting procedures from CBCT images.
