Treatment of comminuted mandibular fractures: a critical review.

The treatment of comminuted fractures of the mandible is challenging due both to the severity of the injuries generally associated with this type of fracture, and the lack of consensus as to the most appropriate treatment method.There are two distinct approaches for treating comminuted fractures of the mandible: closed reduction with maxillomandibular fixation (MMF) - the oldest and classical treatment - and open operation and internal fixation. The morbidity rate of closed reduction is lower but, with the advent of modern anaesthesia and antibiotics, open surgery has become more frequent.

Dimensional error of selective laser sintering, three-dimensional printing and PolyJet models in the reproduction of mandibular anatomy.

Background: Selective laser sintering (SLS), three-dimensional printing (3DP) and PolyJet are rapid prototyping (RP) techniques to fabricate prototypes from virtual biomedical images. To be used in maxillofacial surgery, these models must accurately reproduce the craniofacial skeleton.

Purpose: To analyze the capacity of SLS, 3DP and PolyJet models to reproduce mandibular anatomy and their dimensional error.

The treatment of condylar fractures: to open or not to open? A critical review of this controversy.

The treatment of condylar process fractures has generated a great deal of discussion and controversy in oral and maxillofacial trauma and there are many different methods to treat this injury. For each type of condylar fracture, the techniques must be chosen taking into consideration the presence of teeth, fracture height, patient's adaptation, patient's masticatory system, disturbance of occlusal function, deviation of the mandible, internal derangements of the temporomandibular Joint (TMJ) and ankylosis of the joint with resultant inability to move the jaw, all of which are sequelae of this injury. Many surgeons seem to favor closed treatment with maxillomandibular fixation (MMF), but in recent years, open treatment of condylar fractures with rigid internal fixation (RIF) has become more common.
