Mandible; Deformity
Conditions
Brief summary
Atrophic alveolar bone presents a unique difficulty, preventing correct implant placement and affecting long-term results. There are different techniques that are recommended to restore the proper length of the posterior ridge of the mandible and thus achieve proper form and function, one of those is distraction osteogenesis. Refinements in the technique of distraction can improve the treatment outcome and decrease postoperative complications.
Interventions
DEVICEGuided biaxial alveolar distraction device
A crestal incision will be done, a surgical guide will be placed to assist the correct position of osteotomy, an Extraosseous alveolar distractor will be placed on the ridge to mark screw sites and then will be removed, A distractor will be stabilized to the basal segment with a monocortical screw.

Inclusion criteria
* Patients with the posterior atrophic mandible. * The distance from the alveolar crest to the upper border of the canal is not less than 5 mm. * Adult patients from 30-60 years old with no gender predilection who agreed to present for follow-up visits for a minimum postoperative period of 4 months. * Patientswithanadequateoralhygiene. * The patient should be psychologically accepting of the involved procedures.
Exclusion criteria

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in bone density | Baseline,1 month, 3 months | Bone density at the distracted area, the length will be gained and displacement of transported segment lingually will be evaluated using CBCT |
| Change in Pain scorre | at 1, 7 and 14 days | It will be assessed on daily basis for one week through a 10-point Visual Analogue Scale (VAS). (0-1= None, 2-4= Mild, 5-7= Moderate, 8-10= Severe) |
| change in wound healing | at 1, 7 and 14 days | The sutured wounds will be examined for wound dehiscence as (Yes for present and No for absent) |
| Change in mental nerve reflex | Baseline, after 2 weeks and 1 month | Mental nerve blink reflex responses to electrical stimuli given with a small bipolar pediatric stimulating electrode to the center of the mental nerve distribution on the chin and lower lip on each side will be recorded bilaterally with surface electrodes on the orbicularis oculi muscles with Viking IV EMG equipment |
