The Use of a Novel CAD-CAM Splint to Simplify Open Reduction and Internal Fixation of Mandibular Angle Fracture: A Technical Note

Abstract

Mandibular angle fractures are frequently encountered as they constitute an area of weakness. Complications after open reduction and internal fixation (ORIF) of angle fractures commonly arise due to improper reduction and fixation methods that fail to counteract the dynamic muscle forces present in this region. Conventional reduction methods such as digital manipulation, intermaxillary fixation, towel clip traction, and wiring are associated with various limitations. This technical note highlights the fabrication and use of a computer-aided designing/computer-aided manufacturing–generated splint for ORIF of a superiorly displaced mandibular angle fracture. The splint consisted of 2 components: (1) a distal tooth-borne component to guide the teeth into maximum intercuspation and (2) a proximal bone-borne component to reduce the angle fracture. This composite splint facilitates simultaneous restoration of occlusion as well as reduction of mandibular angle fractures. The advantages of this technique include the following: (1) easy fabrication of splint, (2) easy and precise anatomical reduction of angle fracture, and (3) less operative time.

A Comparative Analysis of Outcome of Open Reduction and Internal Fixation of Mandibular Fracture With or Without Intermaxillary Fixation

“…As society becomes more and more complex as population, traffic, urbanization and industrialization increase, road accidents, industrial accidents, falls, violence and explosions can be expected to increase simultaneously. [1][2] As a consequence, an increase in the number of craniofacial fractures is expected. Due to the anatomical shape of the protrusion of the mandible, which is unique among the bones of the face, the fracture rate is second only to those of the nose.…”
