Localized Alveolar Ridge Augmentation With Dental Implant (RidgeDI)

An Open Label, Non-randomized, Single-arm, Multi-center Study to Assess Localized Alveolar Ridge Augmentation Utilizing INFUSE® Bone Graft Concurrent With Dental Implant Placement

The purpose of this research study is to shorten the treatment time course for patients who are scheduled for surgery to have a dental implant(s) placed into the upper front part of their mouths and need to have more bone in their jaws to support the implant.

Study Overview

• Status: Terminated
• Conditions: Alveolar Bone Loss
• Intervention / Treatment: Device: INFUSE® Bone Graft

Detailed Description

The INFUSE® Bone Graft is a device approved by the FDA to be used instead of using your own bone (from another site on your body) to replace missing bone in your jaw. INFUSE® Bone Graft is commercially available and is made up of 2 parts - recombinant human Bone Morphogenetic Protein-2 (rhBMP 2) placed on an absorbable collagen sponge (ACS). The rhBMP-2 is a genetically altered protein which recruits bone-forming cells to the surgical area and changes local cells to bone. ACS is made from Type I collagen from bovine (cattle) tendon. It helps to hold the rhBMP-2 in place and acts as a support for the growing bone. The sponge itself will reabsorb in time as the new bone forms.

The purpose of this research study is to shorten the treatment time course for the patients. This post-market study has been designed to further evaluate the effectiveness and safety of INFUSE® Bone Graft, along with dental implant placement, in a single procedure.

Cohorts and Interventions

Group / Cohort

Intervention / Treatment

INFUSE® Bone Graft; all study participants will receive INFUSE® Bone Graft

Device: INFUSE® Bone Graft; Patients will be treated with the commercially available INFUSE® Bone Graft material applied to an ACS in the area of the dental implant on Day 0 (Surgery). A follow-up visit will take place 2 weeks after implant of the INFUSE® Bone Graft material, or as regularly scheduled as per the standard of care (SOC) for the facility. Patients will return to the facility for final End of Study (EOS) assessments 6 months after surgery for placement of the appropriate prosthetic, and assessment of osseointegration and stability. Between the follow-up visit and the EOS visit, patients will be seen as per the SOC schedule for the facility.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Time Frame
Stability and osseointegration of endosseous dental implants	6 months post-implantation

Secondary Outcome Measures

Outcome Measure	Time Frame
Evaluate evidence of successful initial INFUSE® Bone Graft and dental implant placement. Assess percent bone fill within the defect and safety of INFUSE®. Outcomes will be assessed via CT scans and periapical X-rays.	6 months post-implantation
