V Shaped Plate Vs Champy Technique in Mandibular Angle Fractures

The Effect of (v) Shaped Plate on Occlusion and Condylar Position Compared to Champy Technique in Fixation of Mandibular Angle Fracture (Randomized Clinical Trial)

assessing fixation of mandibular angle fracture using two different mini plates, the standard champy technique and the new V shaped plate with comparing occlusion and condylar position between the two plates.

The mandible is one of the most frequent bones of the face that is susceptible to fractures because its prominent position, as it comes in the second place after nasal fractures . Mostly, such fractures are a result of trauma caused by vehicle accidents, physical altercations, industrial accidents, falls, and contact sports, males usually suffer from mandibular fractures more than females. The angle of the mandible is the most frequent area of the mandible to be fractured after the body, the reasons behind that is the presence of a third molar especially if it was impacted one which weakens the region even more, another reason is the existence of a very thin cross sectional area compared to the anterior parts of the mandible. Most common causes of mandibular angle fractures are motor vehicle collisions and assaults or altercations. Therefore, the aim of this study is to evaluate a novel method which is using a (v) shaped plate in fixation of mandibular angle fracture, The new (v) shaped plate have provided easy reduction and stabilized fixation along both sides of the fracture, as it has two arms that can be easily adjusted over the angle of the mandible covering both lines of osteosynthesis along the superior border and lateral surface of the external oblique ridge using a single plate. Although champy technique has been proven to be successful way for treating angle fractures with low complication rates it covers only one line of osteosynthesis which is the superior border of external oblique ridge unlike the (v) shaped plate.

its a new plate that have been used in fixation of fractures in various areas of the mandible,V shaped plate was used in the treatment of three angle fracture cases which provided the advantage of including both lines of osteosynthesis which are the superior border and the lateral surface of the external oblique ridge using one plate.

champy technique is one of the standard methods that are used in fixation of mandibular angle fractures by applying a mini-plate in the superior border of the external oblique ridge.

It's Clinically assessed outcome. Follow up will be carried out immediate post-operative (after1 week), 3months and after 6 months for general clinical assessment of the patient including proper occlusion.

C.T scan will be taken post operatively after periods of 1week and 6 months to measure condylar position by specialized (software mimics) C.T superimposition.

Inclusion Criteria: Patients with unilateral angle fracture. Patients free from any systemic diseases that affect bone healing. No sex predilection. Age 18-50 Exclusion criteria: Comminuted angle fractures. Infected angle fracture. Bilateral angle fracture. Patients with any systemic diseases that affect bone healing.
