Trial summary

Straumann Bone Ceramic (SBC) and BioOss will be used as bone grafting materials when there is a need for bone augmentation in the posterior upper jaw. 9 months later the bone formation is evaluated. The patients are followed for 3 years.The study hypothesis is that the SBC is not worse than BioOss. Read more about this study

About this study

Official title: Randomized, Controlled Clinical Study to Compare Bone Formation Around Micro-implants in the Maxilla After Sinus Floor Augmentation With Straumann Bone Ceramic or Bio-Oss in a Split Mouth Design

Straumann Bone Ceramic (SBC) and BioOss will be used as bone grafting materials when there is a need for bone augmentation in the posterior upper jaw. 9 months later the bone formation is evaluated. The patients are followed for 3 years.The study hypothesis is that the SBC is not worse than BioOss.

Read the detailed description

Straumann Bone Ceramic (SBC) and BioOss will be used as bone grafting materials when there is a need for bone augmentation in the posterior upper jaw. The bone grafting materials will be placed into the sinus cavity,(a routine procedure), one material randomly at each side and a micro-implant will be inserted simultaneously. 9 months later the micro-implant is removed and a regular Straumann SLActive implant is inserted. The micro-implant is evaluated histologically. The site is evaluated every 12 months for 3 years in regards to clinical measurements. The study hypothesis is that the SBC is not worse than BioOss.

Study design: Prospective, randomized, open, controlled, single center, split mouth

Study population: 11 male and female patients at an age of between 18 and 80 years, affected by edentulism of both lateral-posterior maxilla and presenting two pneumatized maxillary sinuses and necessitating rehabilitation with implant-supported prostheses will be recruited in the study and treated by means of maxillary sinus floor augmentation and delayed implant placement.

What is being measured

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

  1. Histologically Measured Bone to Implant Contact (BIC)

    Results from morphometric measurements of percentage of new bone in contact with the total surface of the titanium implant, area of new bone and bone graft particles in contact with bone

    Measured: 9 months after implant placement

Secondary outcomes (2)
  1. Implant Survival Rate

    The percentage of implants remaining in the jaw.

    Measured: 12 months after loading the implant

  2. Implant Success Rate

    Implant success is defined as the absence of any continuous peri-implant radiolucency based on radiographic findings, absence of implant mobility, absence of a recurrent per-implant infection with suppuration (where an infection is termed recurrent if it is observed at two or more 3-month follow-up visits after treatment with systemic antibiotics), and bone level changes around the implant less than 1 mm during the first year of loading and less than 0.2 mm per year thereafter.

    Measured: 12 months after loading the implant

Questions about this trial

What is this clinical trial studying?

A study testing Straumann Bone Ceramic and BioOss in people with Jaw, Edentulous, Partially and Alveolar Bone Loss, run by Institut Straumann AG at 1 site in Sweden.

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 9 inclusion and 15 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 31 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 1 site in Sweden. 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 31 Aug 2012). 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?

Histologically Measured Bone to Implant Contact (BIC) (time frame: 9 months after implant placement). 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 NCT00900822, which also lists 2 linked publications.

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 31 Mar 2016; AzTrials last refreshed its copy on 26 Oct 2026.
