About this study

Official title: A Prospective, Multi-centre Study Evaluating Creos™ Xenogain Bone Graft Substitute in Horizontal Ridge Augmentation in the Premolar and Molar Region of the Mandible

This clinical investigation is a prospective, multi-centre study to evaluate bone gain after horizontal augmentation using creos xenogain bone graft substitute. Patients included in the study are in need of a GBR procedure prior to implant placement in the premolar and posterior region of the mandible.

Read the detailed description

This clinical investigation is a prospective, multi-centre study to evaluate bone gain after horizontal augmentation using creos xenogain bone graft substitute.

Patients included in the study are in need of a GBR procedure prior to implant placement in the premolar and posterior region of the mandible.

Primary endpoint include the bone gain after 8 months healing period, while secondary endpoints includes histological analysis 8 months after performance of the augmentation procedure as well as Implant survival, implant success and marginal bone levels evaluated over a period of 1 year after definitive prosthetic delivery.

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

  • creos xenogainDevice

    GBR procedure will be performed using creors xenogain bone graft substitute in patients that need horizontal bone augmentation prior to implant placement. The defect should be located in the pre-molar and molar region of the mandible

What is being measured

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

  1. Bone gain 8 months after bone augmentation procedure for implant placement.

    To evaluate bone gain 8 months after bone augmentation procedure for implant placement.

    Measured: 8 months

Secondary outcomes (6)
  1. Implant survival

    To demonstrate cumulative survival rate of the implants placed in the augmented bone at 6 months and at 1 year after definitive prosthetic delivery.

    Measured: 6 months and 1 year after definitive prosthetic delivery

  2. Implant success

    To demonstrate cumulative success rate of the implants placed in the augmented bone at 6 months and 1 year after definitive prosthetic delivery.

    Measured: 6 months and 1 year after definitive prosthetic delivery

  3. Marginal bone levels

    To demonstrate the changes in marginal bone levels (ΔMBL) around the implants placed in the augmented bone as measured and evaluated by periapical films, 6 months and 1 year after definitive prosthetic delivery

    Measured: 6 months and 1 year after definitive prosthetic delivery

  4. Histological analysis prior to implant insertion including percentage of vital bone, residual graft and connective tissue or other non bone components

    A bone sample using a trephine bur will be collected after 8 months and prior to implant insertion in order to perform histological analysis. The analysis will include the following parameters: percentage of vital bone and residual graft and connective tissue and if present other non bone components

    Measured: 8 months

  5. Soft tissue outcome 1 year after definitive prosthetic delivery

    Soft tissue outcome is a combination of different parameters that include gingival index, bleeding index, keratinized mucosa and pink esthetic score

    Measured: 1 year

  6. oral health related quality of life assessment

    To demonstrate pre- and postoperatively the oral health related quality of life assessment using the Oral Health Impact Profile questionnaire (OHIP-14).

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A study testing creos xenogain in people with Horizontal Bone Augmentation, run by Nobel Biocare at 6 sites in 3 countries.

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 10 inclusion and 13 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: status not confirmed, as of the sponsor's last update on 18 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in Germany, Italy, Serbia. 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?

Results are not available in the source record.

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?

Bone gain 8 months after bone augmentation procedure for implant placement. (time frame: 8 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 NCT03028922, 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 Mar 2020.
