About this study

Official title: Retrospective Observational Study of Implant-supported Restorations With Implants Produced by Additive Manufacturing

This retrospective study aims to value the bone loss and the success and survival of the dental implants produced by additive manufacturing installed in an area grafted with Plenum® Osshp (synthetic bone graft). In addition, the biological and biomechanical performance of implant restorations supported through an observational retrospective solution will be observed. From 50 to 100 survey participants will be selected, who will be invited to attend the clinic for clinical, radiographic, and prosthetic evaluation and successful parameters between baseline, 3, 6, and 12 months. The data obtained regarding bone loss (primary outcome) of the analyzed regions and implant success and survival in area grafted with Plenum® Osshp (secondary outcome) will be evaluated by the paired t-test for the evaluation of the times (3, 6, and 12 months) and survival curves of the installed dental implants.

What is being measured

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

  1. The survival rate of dental implants produced by additive manufacturing installed in pristine bone and grafted areas with synthetic bone graft (Plenum® Osshp).

    The main outcome is the survival rate (%) of successful implant-supported restoration after at least 1-year of occlusal loading (less than 0.5mm of bone loss)

    Measured: 12 months

Secondary outcomes (2)
  1. The survival rate of dental implants produced by additive manufacturing installed in different areas grafted with synthetic bone grafts (Plenum® Osshp)

    Survival rate (%) of successful implant-supported restorations (less than 0.5mm of bone loss) placed in different bone areas (pristine bone, grafted areas with Plenum Oss including maxillary sinus augmentation, guided bone regeneration for both vertical and horizontal augmentation, and extraction sockets).

    Measured: 12 months

  2. Rate of bone loss

    A periapical x-ray will be performed at the implant placement region to check the bone level concerning the implant platform. Then, a vertical line will be drawn from the initial line to the bone level for measurement (mm). Standardized intraoral periapical radiographs will be obtained using a dental X-ray machine with a 35 cm long cone. The exposure parameter was 70 kV (Peak), 15mA, and 1/4s at a focus-sensor distance of 30cm. The X-rays will be captured with a digital camera and transferred to a personal computer. Image processing software will be used to store the scanned images. Subsequently, the images will be made available on a monitor and a linear measurement will be performed with software.

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A study testing Dental Implants installed in an grafted area (sinus lifting), Dental Implants installed in an grafted area (ridge augmentation) and Dental Implants installed in an grafted area (extraction sites) in people with Oral Surgical Procedures, run by M3 Health 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 18 inclusion and 1 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: stopped early, as of the sponsor's last update on 20 Oct 2026. 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?

The study was stopped early (reason given: The study was not terminated because we changed the methodology of the patient recruitment). 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?

The survival rate of dental implants produced by additive manufacturing installed in pristine bone and grafted areas with synthetic bone graft (Plenum® Osshp). (time frame: 12 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 20 Oct 2026.
