About this study

Official title: Compare Articaine 1:100.000, 4% Epinephrine, Subperiosteal With Loco-regional Anesthesia for Placing Dental Implants in Posterior Mandible - Double-Blinded Randomized Clinical Trial

In patients that are going to receive a dental implant in the posterior mandible (distal from canine), does the subperiosteal anesthetic technique with Articaine 1:100.000 4 % Epinephrine compared to the loco-regional one, produces the same analgesia during surgery ?

Read the detailed description

Inter/Intra observer agreement will be made for administration of local subperiosteal, loco-regional anesthesia, operatory evaluation of pain and radiologic examination.

One group will receive articaine 1:100.000, 4% epinephrine subperiosteal and the other 1:100.000 4% epinephrine loco-regional for dental implant installation in posterior mandible.

The evaluation parameters will focus on intraoperatory pain, Intraoperatory anesthetic complications, anesthetic efficiency, correlation between distance from implant to inferior alveolar nerve, intraoperatory pain, post-operatory at 3 and 10 days and correlate changes, and survival rate of dental implants during and post osseointegration period.

What is being measured

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

  1. Anesthesia efficiency

    Evaluate subperiosteal vs loco-regional anesthesia for implant installation in posterior mandible.

    It will be measured by the amount (mean) of anesthesia pre and intraoperatory

    Measured: During Surgery for Dental Implant installation

Secondary outcomes (5)
  1. Intraoperatory Pain

    It will be measured with a direct measure composed by pre and post operatory questionnaires with Visual Analog Scales (VAS) to patient and by two indirect measures, one to the clinician that performed the surgery and one by an external clinic psychologist, both by means of VAS score

    Measured: During Surgery for Implant Installation in posterior mandible

  2. Intraoperatory Anesthesia Complications

    measure the amount of adverse effects of both types of procedure (subperiosteal vs loco-regional)

    Measured: During Surgery for implant installation in posterior mandible

  3. Post-Operatory Outcome Changes

    measure post-operatory magnitude changes in both groups (subperiosteal vs loco-regional anesthesia) from baseline to 10 Days. It will be measured in VAS the amount of pain experienced by the patient.

    Measured: Baseline (T0) 3 Days (T1) 10 Days (T2)

  4. Time of Surgery

    Measure the amount of time needed to perform dental implant installation in posterior mandible in both groups (subperiosteal Vs loco-regional)

    Measured: During Surgical Procedure

  5. Distance To Inferior Alveolar Nerve (IAN)

    measure in a panoramic (orthopantomography) the distance from the implant apex to the most coronal part of the IAN and correlate to the anesthesia efficacy and operatory pain

    Measured: Post operative Panoramic radiograph

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Dental Implants in Posterior Mandible, Subperiosteal 1:100.000 Articaine 4% epinephrine and Loco-regional 1:100.000 Articaine 4% epinephrine in people with Surgical Complications From Local Anesthesia and Dental Implant Failed, run by Implantology Institute at 1 site in Portugal.

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 8 inclusion and 8 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 21 Apr 2020. 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 Portugal. 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?

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?

Anesthesia efficiency (time frame: During Surgery for Dental Implant installation). 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 21 Apr 2020.
