About this study

Official title: A Histomorphometric Analysis of Bone Formation With Three Different Bone Graft Materials Following Sinus Augmentation

The purpose of this study is to compare new bone formation following bone graft in sinus using three different commercially available bone graft materials. The study hypothesis is that there is no difference in new bone formation among three bone graft materials under microscope.

Read the detailed description

The purpose of this investigation is to compare new bone formation through histomorphometric analysis following maxillary sinus augmentation using three different bone graft materials. Null Hypothesis is that there is no histomorphometric difference in new bone formation in maxillary sinuses augmented using three different materials; anorganic bovine bone graft (Bio-Oss), anorganic equine bone graft (Equimatrix) and mineralized bone allograft (OSSIF-i sem). Patients who require sinus augmentation prior to implant placement will be selected to participate in this study. All patients will be randomly placed into three groups according to bone graft materials that will be used. Group A (Control group,n=10): Maxillary sinus augmentation using anorganic bovine bone graft (Bio-Oss), Group B (Test group,n=10):Maxillary sinus augmentation using anorganic equine bone graft (Equimatrix), and Group C (Test group,n=10):Maxillary sinus augmentation using mineralized bone allograft (OSSIF-i sem). All the patients will be treated with the same surgical technique consisting of sinus floor augmentation via a lateral approach.After a full-thickness flap reflection to expose the lateral wall of the sinus each antrostomy will be outlined with a carbide round bur and sinus membranes will be carefully elevated. If a perforation to the sinus membrane occurs, and if the perforation is < 5 mm in diameter and is able to be repaired, the surgeon will continue the procedure. Any perforation > 5 mm will be excluded from this study. Bone graft materials will be placed into the each sinus compartment for the three groups. After 8 months of healing, biopsy specimen will be collected from the previous antrostomy sites. Histomorphometric measurements of the percentage of vital bone of the area of bone. The percentage of non-bone material (allograft or xenograft) and the percentage of connective tissue will be also analyzed. Then the primary hypothesis will be analyzed statistically.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The Percentage of Vital Bone in a Total Amount of a Bone Specimen

    Bone biopsy was taken in a mean of 9.1 months after sinus graft procedure from previous lateral window of maxillary sinus. The bone cores were analyzed though histomorphometric analysis.

    Measured: 24months

Secondary outcomes (1)
  1. The Percentage of Non-vital Bone/Residual Bone Graft Material in a Bone.

    Bone biopsy was taken in a mean of 9.1 months after sinus graft procedure from previous lateral window of maxillary sinus. The bone cores were analyzed though histomorphometric analysis.

    Measured: 24months

Questions about this trial

What is this clinical trial studying?

A study testing Sinus augmentation, Equimatrix and OSSIF-i sem in people with Inadequate Bone Height in Maxillary Posterior Area, run by Loma Linda University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Dec 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 13 Dec 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The Percentage of Vital Bone in a Total Amount of a Bone Specimen (time frame: 24months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Dec 2017; AzTrials last refreshed its copy on 1 Nov 2026.
