About this study

Official title: Osteogenic Effects of Concentrated Growth Factors Applied in Maxillary Sinus Floor Elevation Via a Lateral Window Approach With Simultaneous Implant Placement: a Single-center Randomized Controlled Trial

To investigate the effects of concentrated growth factors applied in maxillary sinus floor elevation via a lateral window approach with simultaneous implant placement on repair of bone defects and new bone formation.

Read the detailed description

Maxillary sinus floor elevation via a lateral window approach is the most effective method of overcoming the shortage of bone mass deficiency in atrophic maxillary posterior region. Bone transplantation is considered to be a prerequisite for the success of maxillary sinus floor elevation. Platelet-rich plasma and platelet-rich fibrin have been used to accelerate bone formation, regeneration, and repair. However, few in-depth studies are reported on the effects of concentrated growth factors on new bone formation.

Being tested
concentrated growth factors, hydroxyapatite and autogenous bone

What participants receive

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

  • concentrated growth factorsOther

    These patients were randomly assigned to receive concentrated growth factors, hydroxyapatite and autogenous bone at bone defect sites in the experimental group.

  • hydroxyapatite and autogenous boneOther

    These patients were randomly assigned to receive hydroxyapatite and autogenous bone at bone defect sites in the control group.

What is being measured

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

  1. Excellent and good rate of bone repair

    X-ray examination was performed to evaluate bone repair as per excellent and good rate.

    Measured: changes of month 1, month 3 and month 6 after surgery

Secondary outcomes (1)
  1. Bone density at bone defect sites

    The thickness of the cortical bone at the defect sites was measured using a dental cone beam CT scanner to reflect bone density.

    Measured: changes of month 1, month 3 and month 6 after surgery

Questions about this trial

What is this clinical trial studying?

A study testing concentrated growth factors and hydroxyapatite and autogenous bone in people with Maxillary Sinus Disease, run by Deyang Stomatological Hospital.

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 14 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: status not confirmed, as of the sponsor's last update on 8 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

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?

Excellent and good rate of bone repair (time frame: changes of month 1, month 3 and month 6 after surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 8 Feb 2017.
