Brief 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. 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.

Conditions

Periodontal Diseases; Dental Implant Failed

Outcome Measures

Primary Outcomes (1)

• The primary outcome variable of the study will be variation in bone remodeling between the initial and final values (measured in mm)

  Bone loss measured from the abutment-implant junction to the first visible bone to implant contact visible in a X-ray

  36 months

Interventions

diagonstic OTHER

The aim of the study will be to evaluate the bone loss and peri-implant complications of short implants produced by additive manufacturing

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

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.

You may qualify if:

• 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.

You may not qualify if:

• 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.
