About this study

Official title: Using Boned-Apatite Cement at the Time of Extractions for Ridge Preservation at These Sites

To assess efficiency of ridge preservation (in vertical and horizontal dimensions) after tooth extraction using Calcium Sulfate with hydroxyapatite(®Bond-apatite) compared to the use of bovine bone substitute (BioOss®) and to extration only as negative control.

Read the detailed description

Dental implants have become in the past ten years a popular and promising treatment in the rehabilitation of missing teeth. However, using implants depends on adequate alveolar bone volume. Anatomical restrictions are mostly present in posterior mandibular and maxillary regions. Alveolar bone loss usually occurs because of active periodontal disease, trauma or teeth extractions.

Teeth extractions are associated with some loss of alveolar bone in the horizontal and vertical dimensions. This loss is more pronounced when teeth are extracted because of periodontal disease. Bone grafts from different origins (autogenic, allogenic, xenogenic or alloplastic) can partly reduce the alveolar bone loss. Different ridge preservation techniques were succesfully used in clinical trials, using membranes only or as a combination of membranes and bone substitutes.

Synthetic bone grafts have been proven successfully for ridge preservation. Calcium sulfate is the oldest material, being in use in dentistry for more than 30 years , and in orthopedics for more than 100 years . Calcium sulfate is completely absorbed and constitutes a matrix on wich bone is able to grow (osteoconductive). It does not induce inflammation and doesn't alter calcium levels in the blood flow.Previous studies has shown that calcium sulfate is completely replaced by bone. On the other hand, fast absorption of calcium sulfates can alter the dimensional stability of the graft. Adding Hydroxy Appatite may improve stability during bone remodeling.

This study includes patients who need extractions of incisors, canines or premolars. The extraction sockets must be mostly intact with a maximum 4 mm of one wall missing in the vertical dimension.

30 patients who need extractions from region of interest, with no extended bony defects, will be enrolled from the department of Periodontology, school of graduate dentistry, Rambam Health Care Campus

What is being measured

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

  1. socket dimensions

    Measurement of socket width (B-L aspect) in two vertical points and Distance from alveolar crest height in the middle of the socket to the marked point in the bottom of the stent.

    Measured: 4 months

Secondary outcomes (1)
  1. Complications

    Complications will be documented: Infection, swelling, discomfort, pain, bone substitutes particles moving away from the tissue.

    Measured: 4 month

Questions about this trial

What is this clinical trial studying?

A study testing Bond Apatite synthetic bone substitute and BioOss bovine bone substitute in people with Alveolar Bone Loss, run by Rambam Health Care Campus at 1 site in Israel.

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 4 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 11 Apr 2018. 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 Israel. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

socket dimensions (time frame: 4 months). 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 11 Apr 2018.
