简要总结
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.

入选标准
- •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.
排除标准
- •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.
