About this study

Official title: Effect of Antibiotic Prophylaxis in Dental Implant Surgery - a Multicenter Placebo-controlled Double-blinded Randomized Clinical Trial

The overall aim of the study is to investigate whether routine administration of antibiotic prophylaxis 1 hour prior to implant surgery may prevent postoperative infection and implant loss in healthy or substantially healthy patients (ASA Class 1 and Class 2).

Read the detailed description

The prevalence of bacteria resistant to antibiotics is increasing and there is a correlation between high consumption of antibiotics and high incidence of antibiotic resistance. It is therefore important to reduce the prescription of antibiotics. Antibiotics in dental care are used to treat oral infections as well as to prevent infections associated with surgical procedures. An example of the latter is antibiotic prophylaxis associated with dental implant surgery in order to reduce the risk of postoperative infection that can lead to loss of implant.The study will be conducted as a multicenter placebo-controlled randomized clinical trial. Eligible patients will be asked for participation and those who leave oral and written information will be included in the study. Patients included will be allocated to either active treatment (antibiotic prophylaxis) or placebo. Both clinicians and patients will be blinded to group affiliation. A total of 10 clinicians in 8 centers in the south of Sweden have agreed to participate and each clinicians will be allowed to use the implants and routines that they usually work with.

Specific aims of the study are to test the following hypotheses:

  1. There is no difference in proportion of patients with early implant losses in patients receiving 2 g of amoxicillin preoperatively and patients receiving identical placebo tablets.
  2. There is no difference in proportion of patients with early infections between patients receiving 2 g of amoxicillin preoperatively and patients receiving identical placebo tablets.
  3. There is no difference in infections (within 3-6 months postoperatively) between patients receiving 2 g of amoxicillin preoperatively and patients receiving identical placebo tablets.

If it appears that antibiotic prophylaxis does not lead to any risk reduction, this result may provide a basis for guidelines rejecting antibiotic prophylaxis in dental implant surgery.

What participants receive

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

  • AmoxicillinDrug

    Also called Amoxicillin oral tablets

    Antibiotic prophylaxis consisting of 4 amoxicillin tablets, totally 2 g, orally 1 hour before implant placement

  • PlaceboOther

    Also called Placebo oral tablets (for Amoxicillin)

What is being measured

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

  1. Implant failure

    Early implant mobility and/or infection, which requires the implant to be removed.

    Measured: 3-6 months after implant placement

Secondary outcomes (2)
  1. Postoperative infection

    Presence of swelling, redness, pus, pain and wound dehiscence

    Measured: 7-14 days after implant placement

  2. Infection

    Presence of any type of infection such as abscess, fistula

    Measured: 3-6 months after implant placement

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Amoxicillin in people with Infection Control and Antibiotic Prophylaxis, run by Malmö University 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 2 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 25 Aug 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 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. Some participants in this study may receive a placebo. 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?

Implant failure (time frame: 3-6 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 NCT03412305, 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 25 Aug 2021.
