Abstract

In 4 patients, who had lost one or both central maxillary incisors due to trauma, the incisal canals were filled with autogenous cancellous bone harvested from the chin. After a healing period of 4–5 months implants were inserted. At the time of implant surgery in all cases the canal appeared to be replaced by cancellous bone and the implants were placed partially into the grafted area. After another 6 months abutments were connected and crowns made. After follow-up of between 12 and 15 months no fixture has been lost.

Augmentation in proximity to the incisive foramen to allow placement of endosseous implants: A case series

Thus, a 2-stage technique was required, as we described in our report. Furthermore, in all our patients, we used retromolar bone instead of chin bone.4,6 The advantages of the retromolar donor site over the chin include minimal patient concern for an altered facial contour and decreased complaints of discomfort (fewer problems during eating and with speech).
To assess whether augmentation in the proximity of the incisive foramen with an intraoral bone graft to allow for reliable placement of implants is achievable, not jeopardizing the nasopalatine nerve and vessels in a way causing patients’ distress.
Five patients who had lost a central maxillary incisor due to trauma, and in whom a deficiency of bone at the palatal side was present in the proximity of the incisal canal, were augmented with autogenous cancellous bone harvested from the retromolar region. After a healing period of 3 months, implants were inserted. Patients’ acceptance, complications, and postoperative morbidity of the procedure were prospectively evaluated by standardized clinical and radiographic examinations up to 12 months after augmentation.
At the time of implant surgery, in all cases there was sufficient bone for insertion of the implants with adequate primary stability. Up to now (follow-up of 12-15 months) no fixtures have been lost and all peri-implant tissues have a healthy appearance. All patients were satisfied.
Augmentation in the proximity of the incisive foramen to enable implant placement appears to be feasible, both from the perspective of the patient and the professional.
Unilateral patent nasopalatine duct: a case report and review of the literature

On the basis of the clinical and radiographic findings, the diagnosis of unilateral PNPD was made. The PNPD was surgically resected together with the IC content as described by Rosenquist and Nyström [33]. After resection of the mucosa around the palatal opening of the duct, the IF was exposed by raising a palatal flap.
A 15-year-old white female sought our institution complaining of a chirping noise during speech and swallowing. The noise was spontaneous, perceptible, and enhanced when hard suction on the anterior palate was performed. The patient reported no trauma, infection, or other clinical feature related to the noise. Clinical examination showed 2 small grooves on both sides of the midline, lateral to the incisive papilla. The left groove was visually deeper. Careful probing with a gutta-percha cone revealed the existence of a communication on this side extending from the mouth to the nasal cavity, which was confirmed clinically and radiographically. Probing was not possible on the right side. The diagnosis was unilateral patent nasopalatine duct, which was surgically treated. We report here a new case of patent nasopalatine duct and also present a review of the pertinent literature.
