Rigid internal fixation of fractures of lower jaw. Multi-functional display device having an electronic programming guide and method for controlling the same. In our study, not a single patient treated by 3-D plate developed infection or plate failure, which is not in accordance with Zix et al. Also, 2-mm, 4-hole with gap conventional 2-D and 6-hole with gap 3-D stainless steel miniplates were used. Quadrangle geometry of plate assures a 3-D stability of fracture sites as it offers good resistance against torque forces, thereby avoiding the need for inter-maxillary fixation, ensuring early restoration of mandibular function, and reduced rate of infection at fracture site postoperatively.

Preoperative OPG show right parasymphysis fracture between right lateral incisior and canine with fracture line runs downward and backward. Also, a broad platform is created that may increase the resistance to the torsional forces along the axis of the plate.

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 3e antibiotic coverage.
In the angle region where horizontal and vertical rami of mandible meet and where powerful elevator muscles are attached to the ramus, strong distractive forces are created; therefore, to counteract these forces, a strong fixation device is required. Advantage of conventional 2-D miniplates over 3-D miniplates is their small size and easy adaptability, which minimizes the chances of tooth damage [ Table 4 ].
Also, 2-mm, 4-hole with gap conventional 2-D and 6-hole with gap 3-D stainless steel miniplates were used.
Conventional 2.0 mm miniplates versus 3-D plates in mandibular fractures
Reduction and fixation of fracture segments was done intraorally under GA, except in some inaccessible angle fractures where transbuccal approach was used. X-ray OPG shows fractured 2. This study consisted of a sample of 28 patients 40 fracture sites divided randomly but equally single-blind control trial study into two groups.
Small size of the plate, easy adaptability, easy placement, and use of intraoral approach led to increased use of mono-cortical plates in maxillofacial surgery. This coincides with the study of Gutwald et al. RESULTS Patients of both groups were evaluated for malunion, non-union, damage to root by screw, implant failure, infection at site, neurosensory deficit, occlusal discrepancy, and postoperative mobility at fracture site.
It consisted of mono-cortical, juxta alveolar, and subapical osteosynthesis without compression and intermaxillary fixation using miniaturized malleable plates. One patient treated by 3-dimensional plates had tooth damage.
Natl J Maxillofac Surg. A multi-functional display device and a method for displaying an electronic programming guide EPG in the same are disclosed herein. Condylar fractures — open vs closed reduction: The small sample size and limited follow-up could be considered as the limitations of this study.
J Oral Maxillofac Surg. There are two fundamentally different philosophies for the treatment of mandible fracture using plates and screws:.
Table 4 Comparsion of complication between group I and group II. Group II was treated using 2-dimensional 2-D 2-mm miniplates. Exclusion criteria for study were comminuted, malunited, and infected fractures as well as mandibular coronoid and condylar fractures.
Because of the quadrangular configuration of the plates, they provided good stability and resistance to torsional forces.
In Group I, none of patients had immediate postoperative mobility present at the fracture site [ Table 4 ]. Nil Conflict of Interest: All patients were within the 3f group of years, excluding medically compromised patients. Preoperative photograph of patient with right parasymphysis fracture showing deranged occlusion.
Difficulty in adaptation, bulk of the plates, scar formation due to extraoral approach, and increased chances of nerve injury were their disadvantages Concept of semi-rigid fixation: Table 3 Distribution of fracture site, favorability of fracture site, methods of fixation of fracture site. In the region posterior to mental foramen, 3-D plates was placed in such a way that upper cross bar was between root apex and inferior alveolar nerve.
Among patients in Group II, in 1 patient, there was intraoral exposure of plate and intraoral pus discharge at left lower-third molar region. National Center for Biotechnology InformationU. Use of straight and curved 3-dimensional titanium miniplates for fracture fixation of mandibular angle. Eight patients had bilateral mandible fracture and 12 bipib unilateral fracture.
