Summary

The aim of this study is to evaluate the effect of sticky bone on acceleration of recovery of the neurosensory dysfunction of the inferior alveolar nerve following inferior alveolar nerve lateralization surgery for implant placement in patients with posterior vertical bone deficiency in order to overcome the main disadvantage of this technique \& provide a reliable,saving time - computer guided simultaneous implant placement- and improved technique.

Detailed description

Lateralization of IAN allows simultaneous implant placement with longer implants and primary stability.2 IAN lateralization provides an option to avoid costly, prolonged bone graftt and also healing periods can be reduced by this option of treatment Vestibular depth remains intact as there is no augmentation in the underlying bone defect. 2 IAN lateralization technique has also some advantages such as less morbidity and less of peri-implant disease.2 In case of the IAN is located in the superior part of the body of the mandible , and presence of mild atrophy of the edentulous alveolar ridge will fetch the alveolar ridge in a close relation to the neuro-vascular bundle, The incidence of "high" IAN locations ranges from 14.6 to 30.7%. 1However there is some complications such as numbness after surgery which is considered as the most common one also prevent thermal conductivity via implants(Kahnberg et al., 2000) so sticky bone is going to be used to act as an insulator between dental imlants \& Inferior alveolar nerve and it contains a number of growth factors so it is predicted to play an important role to enhance recovery of the inferior alveolar nerve after surgery

Conditions

• Dental Implant

Interventions

Type	Name	Description
PROCEDURE	Patients receiving computer-guided immediate implant placement and inferior alveolar nerve (IAN) lateralization only.	Standard procedure without Sticky Bone application.
PROCEDURE	IAN lateralization with computer-guided immediate implant placement using Sticky Bone	The same as the control with additional application of Sticky Bone as an insulator for enhanced neurosensory disfunction
