Short Implants in Unitary Implant-supported Rehabilitations in the Posterior Maxilla and Mandible: 5 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 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.
