Abstract
Inferior alveolar nerve lateralization one of the most common surgeries done to restore the mandibular area with severely atrophied ridges and many methods in this surgery and modifications are present and documented in the literature to decrease complication after IAN lateralization surgery. In present study is randomized clinical trial to assessment of the neurosensory alteration, and marginal bone loss after 6 month and primary stability after IAN lateralization with computer guided surgical technique versus non guided classic technique. A total of 32 sites with severely atrophied posterior mandibular ridge were selected for IAN lateralization procedure,16 sites done by computer guided surgical technique, while the other 16 sites had no guide use in surgery and surgery done by classical technique with a follow up period 6 month. Neurosensory evaluation using the modified MRC scale was held postoperative after 2 weeks, 1month, 3 months and 6 months.Implant stability using Osstell device immediately and 6 months postoperative. Immediate CBCT cuts to measure the level of crestal bone to implant platform and 6 months postoperative measurements was recorded and calculated for marginal bone loss assessment. Results of the present study for the postoperative neurosensory alterations in both study and control group was statistically nonsignificant, after 2 weeks in study group 33.3% of the patients had S3 and/or S3+, while there were 30.8% in control group, after 1 month: 66.7% of the patients had S3 and/or S3+ in study group while there were 77.0%in control. S4 was achieved in 22.2% in study group and 15.4% in control group, after 3 months: 55.6% of the patients had S3 in study group while there were 30.8% in control group
