In conclusion, we investigated the quality of postoperative neurosensory function after IAN transposition for dental implant placement. IAN transposition is a useful method for placing implants in the atrophic posterior mandible. However, the procedure is complicated, with the possibility of some degree of neurosensory disturbance, although in most of our cases, it resolved within a clinically acc...
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.

Although the previous studies reported good results concerning ND in IAN transposition surgery, the methods for evaluating ND differed, and most of the studies did not fully describe the evaluation procedure. The evaluation of ND of the IAN can be performed by purely subjective (questionnaire), relatively objective (static light touch, 2-point discrimination, etc.), and purely objective methods (t...
IAN reposition may serve as a viable treatment option in the severely resorbed mandibles. Repositioning is performed via one of the two surgical techniques, lateralization, or transposition, with lateralization yielding lower degrees of nerve deficiency. In lateralization, the IAN is exposed and retracted laterally, held in this position during implant placement, then released to rest against the ...
In total, eight IAN transposition procedures were performed in seven patients. One patient underwent bilateral surgery. Surgery was performed under general anesthesia in four patients and under local anesthesia in three patients. The IAN was lateralized for a four-tooth breadth on one side, three-tooth breadth on three sides, and two-tooth breadth on three sides. In total, 22 dental implants were ...
This study was conducted in compliance with the principles of the Declaration of Helsinki, and was approved by the Committee for Ethics at Shinshu University School of Medicine. Patients who underwent dental rehabilitation by insertion of dental implants between 2000 and 2012 in our hospital were reviewed. Of these, seven patients underwent transposition of the IAN for dental implant placement and...
Tooth loss is one of the common causes of reduced quality of life in adults. Dental implants have become a widely accepted treatment option for both partially and completely edentulous patients [1–3]. However, in cases of posterior mandibular atrophy, suitably sized implants cannot be placed without encroaching on the inferior alveolar nerve (IAN). In such cases, restorative options include the ...
The purpose of this retrospective study was to accumulate data regarding the quality of postoperative neurosensory function after inferior alveolar nerve (IAN) transposition for dental implant placement.
The study included seven consecutive patients who underwent IAN transposition surgery for the insertion of a dental implant into the atrophic posterior mandible. Of these, six patients (seven sid...
