“…While the introduction of miniplates in the treatment of mandibular fractures led to a notable decrease in surgical soft tissue trauma and improved ease of handling, with sufficient stability and fixation of mandibular fractures, loosening of screws due to transmission of pressure to the underlying bone leads to loss of fracture stability and fixation failure (Gutwald et al, 2003;Sauerbier et al, 2008). Advantages of the locking system are the ease of plate adaptation, enhanced stability without transmitting excessive pressure to the underlying bone, leading to less impairment of blood supply (Ellis and Graham, 2002;Gutwald et al, 2003).…”

SUMMARY. Purpose: The use of a 2.0-mm locking plate system was evaluated in mandibular surgery. Patients and methods: 53 patients (42 male, 11 female) with a total of 56 mandibular fractures were treated with a 2.0-mm mini-locking-plate system and retrospectively examined. Gender, age, cause of fracture, surgical access, classification of fractures, osteosynthesis, postsurgical findings and complications were evaluated. Results: Assault in male patients (mean age 31) was the most common aetiological factor. Fractures in women (mean age 43 years) mostly occurred due to falls. Mandibular angle fractures were the most common and this anatomical site also presented the highest complication rate. Only 6% of patients had minor occlusal disturbance postoperatively, and minor complications (infections and dehiscence) occurred in 14% of patients in this study. Major complications only occurred in one patient included in the study (1.9%). Risk factors for the development of complications in this series were a history of alcohol or tobacco use, mandibular angle fractures, associated facial fractures, presurgical occlusal disturbance and concomitant dental infections. Surgical access to the fracture and the interval from injury to surgery was not associated with the development of complications. Conclusions: The use of a 2.0-mm locking plate system with its advantages of improved handling characteristics, increased stability, shorter surgical time and the preservation of bony perfusion is a viable alternative to conventional miniplates in the management of mandibular fractures.

“…Re-establishment of previous normal tension (alveolar border) and compression (basal portion) of functional bone trajectories is the fundamental prerequisite for the full recovery of the mechanical integrity of the mandible [15][16][17][18]. A disadvantage of conventional bone plate/screw systems is that the plate must be perfectly adapted to the underlying bone to prevent alterations in the alignment of segments and changes in occlusal plane.…”

“…Other studies report favorable results with the 2.0 mm titanium miniplate system [14]. According to Arbeitsgemeinschaft für Osteosynthesefragen (AO)/Association for the Study of Internal Fixation (ASIF) principles, the main objective of open reduction and rigid internal fixation in the management of mandibular fractures is to achieve undisturbed healing and immediate restoration of form and function without the adjunctive use of maxillomandibular fixation (MMF) [15][16][17][18]. To overcome this problem, the concept of locking bone plates was introduced.…”

Purpose The purpose of this study was to evaluate the efficacy and comparison between 2.0 mm locking plate system and 2.0 mm Champy's titanium mini plating system in mandible fractures. Materials and Methods A total of 20 patients with mandibular fractures were selected and divided into two groups A and B on randomized basis. Group A was treated with open reduction internal fixation using 2.0 mm locking plates and group B with 2.0 mm Champy's titanium miniplates. All patients were followed up for 12 weeks postoperatively.Results Results of the study show less screw loosening, less precision in plate adaptation and less alteration of the osseous or occlusal relationship upon screw tightening in group A. Chi square test was applied to compare the results between the two groups. Statistical analysis did not show significant difference of incidence of malocclusion between the two groups (p value = 0.606). Statistical analysis using un-paired t test showed significant difference of working time between the two groups (p value = 0.00296). When comparing the overall complication rates according to plates used, the v 2 test showed no statistically significant difference between the locking and nonlocking plates (p [ 0.05).Conclusion It is observed in our study that the locking plate/screw system offers significant advantages over the conventional plating system. The precise adaptation required for using conventional plates is not needed when this locking plate/screw system is used. Locking plate/ screw system provides better stability than the conventional plate/screw system.

“…19 Axial loads are those that produce compression forces or tensions in a structure. 20,26 They act at points of contact that may serve as a screen or friction zone and consequently they may be influential in inducing rotation or displacement. 19 In a clinical situation, it is important to be aware that effects of bending forces are far more important than those of axial forces.…”

“…Furthermore, studies using 3D models have shown that the areas of tension and compression are not fixed but are liable to alternate with one another. 6,18,[26][27][28] Other studies evaluating the use of RIF have applied the forces to the region of the central incisors, 29,30 which offers only a very small area of contact, making it difficult to accommodate the testing device and increasing the likelihood of its slipping from the point of contact and altering the results. 19 Our study took heed of the various recommendations made by Tams et al 25 , who determined the most effective positioning of the plates, and took particular care in the case of the superior border to respect the anatomical limits of the tooth root apices.…”

Abstract. This study constituted a comparative assessment of the mechanical resistance of square and rectangular 2.0-mm system three-dimensional miniplates as compared to the standard configuration using two straight miniplates. 90 polyurethane replica mandibles were used for the mechanical trials. Groups 1, 2, and 3 simulated complete symphyseal fractures characterized by linear separation of the central incisors; groups 4, 5, and 6 simulated parasymphyseal fractures with an oblique configuration. Groups 1 and 4 represented the standard method with two straight miniplates set parallel to one another. Square miniplates were used in groups 2 and 5, and rectangular miniplates in groups 3 and 6. A universal testing machine set to a velocity of 10 mm/min and delivering a vertical linear load to the first left molar was used to test each group. Maximum load values and load values with pre-established dislocation of 5 mm were obtained and submitted to statistical analysis using a calculated reliability interval of 95%. The mechanical performances of the devices were similar, except in the case of rectangular plates used in the parasymphyseal fractures. The innovative fixation methods used showed significantly better results in the case of symphyseal fractures.
