About this study

Official title: Randomised, Clinical Controlled Study on Treatment of Intra-bony Defects With Enamel Matrix Protein (Emdogain®) vs. Nanocrystalline Hydroxyapatite (Ostim®)

The aim of this investigation is to determine whether a synthetic hydroxyapatite is as effective as an enamel matrix protein for periodontal regeneration in patients who have intra-bony periodontal defects.

Read the detailed description

Regeneration of periodontal tissues that have been diminished by periodontal disease is the main goal of periodontal therapy. While conventional surgical therapy only offers limited potential towards recovering tooth-supporting tissues, more recently developed techniques lead to a greater and more predictable regeneration of the periodontal structures. Among these techniques, application of enamel matrix proteins or bone grafts can promote periodontal regeneration.

The study is a prospective, controlled, mono-center, randomized, clinical trial, that is open to the operator, blinded to the examiner. It will be conducted in a parallel group design. Participants who have at least 1 intra-bony periodontal defect will receive regenerative surgery at baseline with the randomly selected devices. A newly developed synthetically manufactured bone grafting material made of hydroxyapatite (Ostim) will be the product under investigation. An enamel matrix protein derivative (Emdogain) will act as control device. Both materials will be applied in intra-bony defects during periodontal flap surgery. Follow-ups will take place at 7 and 14 days post surgery, and at 3, 6, 9, and 12 months.

The primary aim is to compare the effectiveness of the test product with the control in the treatment of 1- and 2-wall intrabony periodontal defects on the amount of bone fill 12 months after surgery. Secondary parameters will be the clinical attachment level gain and reduction of probing pocket depth at 6 and 12 months.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • OstimDevice

    Also called synthetic hydroxyapatite

    Ostim® is synthetically manufactured and comprises nanocrystalline hydroxyapatite. The small particle size facilitates resorption. Ostim is an aqueous watery paste and can be used to fill bone defects or to build up bony structures in the region of the jaws. Ostim is osteoconductive, facilitating bone growth. It will act as a scaffolding for the new bone. Ostim is absorbed during the healing process, in the beginning it is osseously interweaved and finally replaced by natural bone.

  • EmdogainDevice

    Also called enamel matrix protein

    Emdogain® consists of sterile lyophilised Enamel Matrix Derivative with sterile aqueous solution of Propylene Glycol Alginate, 30 mg/ml.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ostim and Emdogain in people with Periodontal Disease and Periodontal Attachment Loss, run by Technische Universität Dresden at 1 site in Germany.

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 8 inclusion and 23 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 18 Jan 2012. 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 Germany. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Amount of bone fill after surgery (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00757159, which also lists 1 linked publication.

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 18 Jan 2012.
