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 7 and 8 mm implants with new macrogeometries and surface treatments, in addition to the application of Morse taper prosthetic connections, has shown results that increasingly encourage their use. However, the longevity of these rehabilitations needs to be constantly evaluated. In this work, unitary implant-supported rehabilitations in the posterior jaws, supported by short (7 and 8 mm) tapered Morse connection implants, will be followed for a period of 5 years. A total of 100 subjects rehabilitated with tapered Morse connection implants, with diameters between 3.5 and 4.5 mm, will be evaluated. Peri-implant bone remodeling, implant stability measured through ISQ and clinical parameters will be evaluated per implant and over the evaluation time. Periapical radiographs will be obtained and digitized, analyzed by software and compared with the initial data. The data obtained will be analyzed, allowing longitudinal evaluations and the success rate of implant restorations supported by short implants.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: Yes
• 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 (Implacil De Bortoli, São Paulo, SP, Brazil) in the posterior region of the jaws for single-sided unsupported restorations, will be included in this study. Individuals will also need to have at least initial radiographic controls (immediately after implant placement) and 12 and 60 months of follow-up after implant placement. Individuals will be included in the population sample, with the following criteria observed: location, implant installation region, implant diameter, and adaptation.

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.
