About this study

Objectives: To compare the stability of implant surface treated by dual acid etching (Porous)and implants with anodized surface (Vulcano) over a period of 16 weeks after installation.

Methods: it will be a clinical study with individuals with missing teeth requiring rehabilitation with dental implants in the maxilla and that fulfill the study inclusion criteria. The research sites will be randomized into two groups: the control group patient's sites receive implant surface treated by dual acid (AR Torque Porous, Connection Implant Systems, Aruja, Brazil) and in the test group implants with anodized surface (AR Torque Vulcano-Actives, Connection Implant Systems, Aruja, Brazil). The evaluation of the stability of the implants will be made over 16 weeks, through resonance frequency analysis with Osstell (Integration Diagnostics AB, Gothenburg, Sweden). Data will be analyzed using descriptive statistics and comparative.

What participants receive

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

  • RFADevice

    Also called Osstell mentor, resonance frequence analysis

    Each week since the surgery the implant stability will be measure with the Osstell mentor to verify the resonance frequence analysis, using the smartpeg number 21

What is being measured

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

  1. implant loss

    During the osseointegration, if the implant lose his stability and if it show spin and if the patient have pain, the implant will be removed and the implant will be considered lost

    Measured: 4 months

Secondary outcomes (1)
  1. ISQ analysis

    Since the implant installation, for the next 8 weeks, and after for the next 4 months, the implant stability will be measure with the Osstell, that will return a number between 0 and 100. This represents the Implant Stability Quotient (ISQ). The difference between the ISQ results will be the secondary outcome measure

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study testing RFA in people with Edentulous Jaws Partially, run by University of Sao Paulo at 1 site in Brazil.

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 4 inclusion and 7 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 15 Feb 2013. 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 Brazil. 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?

implant loss (time frame: 4 months). 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 15 Feb 2013.
