Abstract:
Statement of the Problem: One of the anatomical obstacles for dental implants placement in the upper jaw is the nasopalatine canal. The neurovascular contents include nasopalatine nerve, terminal branch of nasopalatine artery and anastomoses with greater palatine nerve and artery. This gives innervation and vascularization for the upper anterior region from the right canine to the left canine. Unfortunately, after extraction of the anterior maxillary teeth, high resorption rate happens on the area. In addition, presence of the incisive canal jeopardizes the ideal position of the implants placement. As a result, enucleation of the canal content and then replaced by bone graft or substitute is necessary to improve the bone bed. Neurological impairment of the soft tissue such as paresthesia or dysesthia may exist after enucleation of the canal. In order to prevent any change in sensation and having bone augmentation at the same time, partial removal of the canal content (coronal 2/3 of its contents) and placement of allograft bone is presented in this case report. Re-entry surgery after six month of the surgical site showed an adequate bone. An implant was placed then a prosthetic restoration was placed. After one year of follow up the implant was successful and no sensory disturbances were shown. A comparison was presented before and after the treatment of the case. Clinical photos and CT figures were included.
