Objectives:
This study aimed to evaluate surgical stability and cosmetic outcomes in patients with mandibular angle fractures (MAFs) using an angled screwdriver (ASD) versus transbuccal trocar (TBT) for single locking plate fixation.
Methods:
A prospective cohort clinical study was done on 44 male patients (88%) and 6 (12% females patients with MAFs, categorized into 2 groups. Group A patients were treated with strictly intraoral vestibular incision using an angulated screwdriver; group B was treated with TBT. Both groups placed a single locking 2.0 mm mini-plates at the inferior border. The main outcome variables were the perioperative complication rate.
Results:
There were no statistical differences between both groups regarding postoperative wound dehiscence, screw or/and plate looseness, infection rate, and inferior dental nerve injury. The study (ASD) approach took 28.10±3.3minutes, while the TBT approach took 37.40±1.75minutes, indicating a highly significant difference in operating time (P=0.001). Post-operative edema had decreased significantly in the ASD group.
Conclusion:
According to the present results, a strictly intraoral approach for ASD enabled stable fixation of MAFs using a single mini-locking plate. This can significantly reduce operation time and postoperative edema and prevent extraoral scarring.
Purpose:The current study was conducted to evaluate, clinically and radiographically, the results of defective ridge augmentation by external oblique ridge graft with or without the use of computer-generated surgical guide. Patients and methods: Twelve patients with alveolar ridges defect were included in this study. The patients were divided into 2 groups: Group A; The alveolar ridges defect augmentation from external oblique ridge graft using Khoury technique with computer-designed generated surgical guides. Group B; The alveolar ridges defect augmentation from external oblique ridge graft using traditional Khoury technique. Clinical and radiographic follow up was performed for 6 months. Treatment changes were evaluated for each group and a comparison was done between the 2 groups. Data were analyzed using paired t-test for each group and student t-test to compare between the two groups. Results: There was a significant increase in bucco-lingual/palatal ridge dimensions between the two studied groups. While the minimal bone distances to the nerve differ significantly (p<0.05), the computer guided group had greater amount of bone remaining around the nerve than non-guided group. Conclusion: Computer assisted surgical guides allow for accurate precise osteotomies providing safe and quick surgery that reflects positively on the postoperative clinical outcomes.
