Conventional 2.0 mm miniplates versus 3-D plates in mandibular fractures.

Sadhwani BS, Anchlia S - Ann Maxillofac Surg (2013)

Bottom Line: Chi-square test.The results of this study suggested that the treatment of mandibular fractures (symphysis, parasymphysis, and angle) with 3-dimensional plates provided 3-dimensional stability and carried low morbidity and infection rates.The only probable limitations of 3-dimensional plates were excessive implant material due to the extra vertical bars incorporated for countering the torque forces.

ABSTRACT

Aim: To compare and evaluate the treatment outcome and postoperative complications in mandibular fractures using 2- and 3-dimensional miniplates.

Materials and methods: This study consisted of a sample of 28 patients (40 fracture sites) divided randomly but equally (single-blind control trial study) into two groups. Each group contains 14 patients (20 similar fracture sites in each group). Group 1 was treated with open reduction and internal fixation using 3-dimensional (3-D) miniplates. Group II was treated using 2-dimensional (2-D) 2-mm miniplates.

Results: Out of 14 patients treated by conventional 2-mm miniplates, 2 patients developed occlusal discrepancy, another 2 had postoperative mobility at fracture site, and 1 developed plate failure and subsequent infection, which was treated by removal of the plate under antibiotic coverage. One patient treated by 3-dimensional plates had tooth damage.

Statistical analysis: Chi-square test.

Conclusion: The results of this study suggested that the treatment of mandibular fractures (symphysis, parasymphysis, and angle) with 3-dimensional plates provided 3-dimensional stability and carried low morbidity and infection rates. The only probable limitations of 3-dimensional plates were excessive implant material due to the extra vertical bars incorporated for countering the torque forces.

Mentions: The patients were divided randomly (single-blind control trial study) into two groups of 20 patients each, but the number of patients of each type were divided equally. Group I was treated with open reduction and internal fixation (ORIF) using 3-D miniplates and Group II were treated with conventional 2-mm (2-D) stainless steel miniplates. Also, 2-mm, 4-hole with gap conventional 2-D and 6-hole with gap 3-D stainless steel miniplates were used. Three-dimensional designs were formed by joining two 2-D miniplates with interconnecting vertical crossbars. Then, 2 × 8 mm and 2 × 10 mm stainless steel self-tapping screws were used to fix the plates. The diameter of head of screw was 2.8 mm with countersinking of the head corresponding to the 30-degree beveled hole in the plate [Figure 1].
