Short Implants Produced by Additive Manufacturing in the Posterior Jaws: 3 Years of Follow-up
An observational study of Periodontal Diseases and Dental Implant Failed, run by University of Guarulhos at 1 site in Brazil.
Trial summary
Implant-supported rehabilitation of regions with severe bone resorption is a challenge for implant dentists. Structures such as the maxillary sinus and the inferior alveolar canal often make it impossible to use implants of lengths considered standard in the literature. Read more about this study

- Ages 18 years and older
- All sexes
- Adult, Older adult
Study population: Individuals (> 21 years old), of both sexes, specifically rehabilitated with Morse connection implants (Plenum Bioengenharia, Jundiai, SP, Brazil) in the posterior region of the jaws for implant-supported restorations, will be included in this study. Subjects will need to have at least baseline radiographic controls (immediately after implant placement) and radiographic controls at 12 and 36 months after implant placement. Individuals will be included in the population sample based on the following criteria: location, region of implant installation, implant diameter, and adaptation.
Who may be able to join
- Individuals (> 21 years old) with Morse connection implants in the posterior region of the jaws for implant-supported restorations; baseline radiographic controls (immediately after implant placement) and radiographic controls at 12 and 36 months after implant placement.
Who cannot join
- Immediate implants will be excluded; individuals with clinical records who, throughout the study, do not have radiographs for evaluation and/or radiographs of poor quality that make radiographic measurements impossible; medical records with insufficient data, filled out inappropriately, or that indicate doubt about the details of the procedure performed.

About this study
Official title: Short Implants Produced by Additive Manufacturing in Implant-supported Rehabilitations in the Posterior Sector of the Maxilla and Mandible: 3 Years of Follow-up
Implant-supported rehabilitation of regions with severe bone resorption is a challenge for implant dentists. Structures such as the maxillary sinus and the inferior alveolar canal often make it impossible to use implants of lengths considered standard in the literature. The use of short implants produced by additive manufacturing (AM) provides a new surface, promoting osseointegration and reducing problems such as peri-implantitis. However, longitudinal evaluations of implants produced by AM are still scarce in the literature. A total of 100 subjects rehabilitated with short implants produced by MA, with diameters between 4.0 to 6.0 mm and 5 to 7 mm in length, will be evaluated. Peri-implant bone remodeling, as well as clinical parameters, will be evaluated by implant and throughout the evaluation time. Periapical radiographs will be obtained and scanned, analyzed by software, and compared to baseline data. The data obtained will be analyzed, allowing longitudinal evaluations and the success rate of implant restorations supported by short implants.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Implant-supported rehabilitation of regions with severe bone resorption is a challenge for implant dentists. Structures such as the maxillary sinus and the inferior alveolar canal often make it impossible to use implants of lengths considered standard in the literature. The use of short implants produced by additive manufacturing (AM) provides a new surface, promoting osseointegration and reducing problems such as peri-implantitis. However, longitudinal evaluations of implants produced by AM are still scarce in the literature. A total of 100 subjects rehabilitated with short implants produced by MA, with diameters between 4.0 to 6.0 mm and 5 to 7 mm in length, will be evaluated. Peri-implant bone remodeling, as well as clinical parameters, will be evaluated by implant and throughout the evaluation time. Periapical radiographs will be obtained and scanned, analyzed by software, and compared to baseline data. The data obtained will be analyzed, allowing longitudinal evaluations and the success rate of implant restorations supported by short implants.

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 primary outcome variable of the study will be variation in bone remodeling between the initial and final values (measured in mm) (time frame: 36 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.
