About this study

Official title: Comparative Clinical and Histological Investigation of Graft Integration Following Piezosurgically Retrieved Lateral Bony Wall Repositioning in Maxillary Sinus Floor Augmentation - Prospective Randomized Controlled Study

The aim of the present prospective randomized controlled study is to clinically and histologically investigate the safety and efficacy of bony wall repositioning compared to rotary window preparation with membrane coverage in maxillary sinus floor augmentation.

Read the detailed description

40 patients were randomly divided in two study groups after radiological and clinical evaluation. Both groups received bone grafting by a xenogeneic bone substitute (BSM, cerabone, botiss biomaterials GmbH, Zossen, Germany) using the lateral approach. In the bony wall group (BW), following piezosurgery the retrieved bony wall was repositioned. In the collagen membrane group (CM), the lateral window was created by rotary instruments, covered via a native collagen membrane (collprotect, botiss biomaterials GmbH, Zossen, Germany). After 6 months, biopsies were taken to analyze both approaches in terms of new bone formation. Duration of treatment, the number of perforations, postoperative patient discomfort were registered. Established histopathological analysis and histomorphometrical measurements to analyze the tissue reactions and the tissue distribution, i.e., the fractions of newly formed bone tissue (NB), of remaining bone substitute material (BSM) and connective tissue (CT), were conducted.

What participants receive

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

  • Maxillary sinus augmentationProcedure or surgery

    Also called Sinus lift

    The surgery was performed under local anaesthesia in both groups, lateral window preparation and window coverage was carried out based on randomization.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Maxillary sinus augmentation in people with Maxillary Sinus Augmentation, run by Semmelweis University at 1 site in Hungary.

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 6 inclusion and 10 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 23 Mar 2021. 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 Hungary. 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?

Duration of surgery (time frame: During smaxillary sinus augmentation). 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 NCT04811768, 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 23 Mar 2021.
