Dental restoration by means of dental implants can provide good functional rehabilitation, particularly in patients with atrophic mandibles. IAN lateralization is a useful method for placing implants in the atrophic posterior mandible. However, there is a possibility of the neurosensory function of the IAN being disturbed, although in most cases, it resolves within a clinically acceptable period.

Piezosurgery is a recently developed system for cutting bone with microvibration [18]. The device cuts mineralized tissue exactly and smoothly, while adjacent soft and nerve tissues remain unharmed because of the cessation of surgical action when the scalpel comes into contact with non-mineralized tissues [19]. The technique has shown to be feasible in IAN transposition with the advantages of smaller osteotomies and preservation of the vascular-nervous bundle [20]. The longer time required for the operation has been reported as a disadvantage [21].

As another treatment options against the vertical discrepancy of the alveolar ridge, the placement of short implants has performed with high success rate [22]. Nevertheless, it is pointed out that biomechanics is related to the denture design, while is directly associated with the mean rates of success and failure, and the use of short implants and dentures with excessive lever arms is a factor for failure [6, 7].
