Aim: To evaluate neurosensory disturbance after using separators Vs chisels in bilateral sagittal split osteotomy. Methods: A total of (18 patients) 36 sides indicated for BSSO randomly assigned to 2 equal parallel groups; 9 patients (18 sides) treated using chisels (control group) and 9 patients (18 sides) were treated by separators (intervention group). The neurosensory disturbance was assessed for each side. Result: After one year follow up in separator group showed neurosensory dysfunction by 11.1% while chisel group showed 44.4%. Conclusion: The use of separators (splitting forceps and elevators) led to a low percentage of persistent post-operative neurosensory dysfunction.

BACKGROUND: Short implants have been proposed as an option for management of deficient alveolar ridges without the need for complex augmentation procedures. AIM: In this study, we aim to assess the use of short and ultrashort implants for the management of deficient alveolar ridges in posterior mandibular and maxillary areas with a 1-year post-loading follow-up. METHODOLOGY: Ten patients were recruited in this trial with a total of 14 implants to be placed. The patients all needed implants in the maxillary/mandibular posterior regions for prosthetic rehabilitation with deficient alveolar ridge heights. Implants of 5 mm diameter and lengths either 6 or 8.5 mm were to be placed in the edentulous spaces after proper radiographic assessment. Two-stage surgeries were followed with ¾ months between implant placement and loading. The follow-up lasted for a year to allow for peri-implant clinical assessment and radiographic analysis. RESULTS: All patients showed uneventful healing and no infection, wound dehiscence or inflammation was noted. Prosthetic rehabilitation was successful and satisfactory to the patients. None of the cases showed excessive marginal bone loss and stability was maintained at acceptable levels to the end of the follow-up period. CONCLUSION: Within the limitations of this study, short and ultrashort implants seem like a valid option for management of posterior edentulous regions with deficient ridge heights.
