简要总结
Study the effect of neurectomy of nasopalatine nerve on the sensation of anterior palate in patients undergoing rehabilitation of anterior maxillary ridge with dental implant
详细描述
Replacement of missing teeth in the anterior maxilla could be challenging if enlargement of the nasopalatine canal which is located in the midline of the palate posterior to the maxillary central incisors or ridge atrophy occur after tooth extraction. This could place the neurovascular content of the nasopaltine canal in the path of the dental implant which may lead to complications such as nasopalatine canal cyst, sensory dysfunction or implant failure. Technique to overcome this problem have evolved including neurectomy of the nasopalatine canal content and obliteration of canal with bone graft.
Loss of sensation in anterior palate following this procedure could be an annoying complication for patients. In recent studies regaining of sensation following such procedure have been reported, Confirmation of such results is essential to rule out the side effect of loss of sensation in the anterior palatal region

结局指标
主要结局
two point discrimination test
时间窗: six months
This test will be performed using a calliper, the two points of the calliper are opened progressively in 1mm increments and care should be taken that the two points are touching the mucosa in the same time until the patient can discriminate two points of contact at which the distance between the two points is recorded
