Han J, et al. - This prospective, multi-center study was performed to evaluate clinical and radiographic outcomes of 6 mm-short implants placed in the posterior maxilla and mandible applying an early loading protocol. In posterior regions with low marginal bone resorption, the use of splinted 6 mm-short implants was a viable treatment. Among patients with known risk factors, early loading after 6 weeks ought to be undertaken cautiously.
