Aim of Study: was to compare both clinically and radiographically between the three-dimensional plates, 2.4 reconstruction plates and superior border Champy's single miniplate fixation in the treatment of mandibular angle fractures.
Materials and Methods: The study enrolled patients who suffered from mandibular angle fractures, presented to the outpatient clinic of the oral and maxillofacial surgery department, faculty of dentistry, October 6 University as well as to the emergency unit of October 6 University Hospital. Patients were divided into 3 equal groups; Group I where open reduction and internal rigid fixation (ORIF) was performed by using 3 Dimensional miniplates through an intra-oral approach assisted by transbuccal trocar. Group II where ORIF was performed by 2.4 reconstruction plate through an extra-oral Risdon approach. Group III where ORIF was performed using single superior border Champy's miniplate through an intra-oral approach.
Follow up were scheduled 1 week then 1,3 and 6 months post-operatively. Intra-operative outcomes included: ease of accessibility, ease of adaptation, need for post-operative IMF and approach related complications.
Results: Statistical analysis of this study concluded that (Group I) presented statistically significant lower infection rate and lower possibility of sensory and motor nerve affection (Group I) and (Group II) presented proper occlusion, more segment stability and fracture rigidity in the treatment of mandibular angular fractures in comparison to (Group III).
Conclusion: The 3D plates demonstrated a superior advantage over the 2.4 Reconstruction plates of ease of insertion transbuccally avoiding any extraoral cutaneous scars, lower infection rates and negligible possibility of facial nerve affection.
