Who may be able to join

  • Males and females were at least 18 years of age and not more than 70 years old
  • A dental implant procedure was foreseen in the maxilla region corresponding to maxillary sinus
  • Patients presented a bone defect in the sinus area, which needed a sinus floor elevation to place one or more dental implants
  • The patients were unilaterally or bilaterally edentulous in the maxillary region corresponding to the sinuses
  • Residual alveolar crest height of the lateral-posterior segments of the edentulous maxilla below the floor of the maxillary sinus was less than 8 mm and at least 3 mm, measured by CT scans. Furthermore, residual alveolar crest width should be at least in average 6 mm measured by the CT scans
  • Patients were committed to the study

  • Medical conditions requiring prolonged use of steroids
  • Standard blood test performed by the medical practitioner of the patient showing: leukocyte dysfunction and deficiencies
  • Haemophilia, bleeding disorders or cumarin therapy

  • Local inflammation, including untreated periodontitis to residual dentition
  • Mucosal diseases such as erosive lichen planus
  • History of local radiation therapy
  • Presence of oral lesions (such as ulceration, malignancy)

  • Patients presenting clinical and radiological signs and symptoms of maxillary sinus disease
  • Patients presenting with residual alveolar crest height of the lateral-posterior segments of the edentulous maxilla below the floor of the maxillary sinus less than 3 mm and residual alveolar crest width less than 6 mm (measured by the CT scans)
  • The reduction in residual bone height was determined by sinus pneumatization and not by vertical resorption of the residual alveolar crest with increased interarch distance. Patients with increased interarch distance were excluded from the study
  • Existing teeth in the residual dentition with untreated endodontic or cariologic problems
  • Horizontal or vertical augmentation to correct the vertical inter-arch distance or to correct horizontal defects

About this study

Official title: Maxillary Sinus Grafting With Bio-Oss or Straumann Bone Ceramic Followed by Delayed Placement of Straumann Dental Implants: A Comparative Histomorphometric and Clinical Study

The purpose of the study was to test a clinically relevant non-inferiority of Straumann BoneCeramic treatment compared to Bio-Oss treatment 180 to 240 days after sinus grafting procedure.

Read the detailed description

This is a prospective, controlled, randomised, multicenter study. The total study duration for each patient should be three years.

In total 13 visits per patient are scheduled in this study.

The study device Straumann Bone Ceramic is CE-marked.

Height centers in Italy will participate.

What is being measured

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

  1. Histological evaluation of the ratio between new bone and residual graft material at the implant site 180 to 240 days after graft-placement.

    Measured: 180 to 240 days

Secondary outcomes (3)
  1. Histomorphometric evaluation of the amount of new bone, soft tissue and remaining graft in the treatment, control and in a 1mm compartment 1mm close to the autogenous bone and the amount of new bone on contact with the graft.

    Measured: 180 to 240 days

  2. Evaluation of the survival and success rate of Straumann dental implants placed in the grafted areas

    Measured: 3 years

  3. Clinical evaluation of peri implant soft tissue

    Measured: 3 years

Questions about this trial

What is this clinical trial studying?

A study testing Straumann BoneCeramic and Bio-Oss in people with Teeth Loss and Bone Loss, run by Institut Straumann AG at 8 sites in Italy.

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 7 inclusion and 32 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 3 Mar 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in Italy. 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?

Histological evaluation of the ratio between new bone and residual graft material at the implant site 180 to 240 days after graft-placement. (time frame: 180 to 240 days). 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 NCT00901121, 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 3 Mar 2016.
