Three-dimensional locking plate and conventional miniplates in the treatment of mandibular anterior fractures

Abstract

Context:Three-dimensional (3D) locking plates has been designed with the hypothesis that this will overcome the disadvantages of both the systems and also advantages of both systems will be combined for the management of mandibular fractures.Aims:The purpose of this study was to evaluate the efficacy of 2-mm 3D locking miniplate in the management of anterior mandibular fracture and to compare it with Champy's miniplate.Settings and Design:A prospective, randomized, clinical trial was carried out in thirty patients who were divided equally in two groups.Subjects and Methods:Group I and Group II patients were treated with 2-mm 3D locking plates and 2-mm standard miniplates, respectively. They were evaluated according to the outcomes of the study, that is, working time, wound dehiscence, infection, segmental mobility, postoperative occlusion, need for postoperative intermaxillary fixation (IMF), and radiological evaluation of reduction and fixation.Statistical Analysis Used:Student's t-test and Mann–Whitney test were used to compare the two systems. The data were analyzed using Statistical Package for the Social Science version 14.0. The P value was taken as significant when <0.05 (confidence interval of 95% was taken).Results:The mean duration of procedure for Group I was found to be 49.33 min, whereas for Group II was 59.67 min. There was significantly greater pain on day 1 and at 1 week in Group II patients. 6.7% (n = 1) of both groups showed incidence of infection. Postoperative stability was adequate in most cases except in one patient (n = 1) of 3D locking system, which was revealed as postoperative occlusal disharmony, unsatisfactory radiological reduction of the fracture fragments, and the segmental mobility. There was no incidence of wound dehiscence, tooth damage, and nerve damage in either group.Conclusions:The result of the study can conclude that there is no major difference between both systems in terms of treatment outcome.

Comparison of Bone Healing After the Use of a Three Dimensional Miniplate and a Conventional Miniplate in Mandibular Body Osteotomy (An Experimental Study)

“…On the basis of this study, we can conclude that 3D plate is an alternative approach with a similar outcome profile to miniplates. This finding was in accordance with the clinical work of Budhraja, et al: 3-D plate versus conventional miniplates (27).…”

“…Farmand emphasized in his results the decrease in fixation material needed to stabilize the fracture and that no patient required additional fixation for fracture stabilization (6). The 3-D mini plates itself was a misnomer as the plates themselves were not 3 dimensional, but holds the fracture segments rigidly by resisting the 3 dimensional forces namely shearing, bending and torsional forces occurring on the fracture site in function (27).…”

Complications of locking and non-locking plate systems in mandibular fractures

“…Conflict of interest was not reported in 12 studies 12,[25][26][27]32,33,37,39,41,42,46 . In 18 studies informed consent was reported 11,13,22,23,27,29,31,[35][36][37][38][43][44][45][48][49][50][51] .…”

“…In total, 16 studies were selected for the meta-analysis. Reasons for not being included in the meta-analysis were: comparison of different diameter plates n = 5 38,39,41,44,45 (e.g., 2.0-mm locking vs. 2.3-mm non-locking), comparison of different plate designs n = 8 35,37,40,42,43,48,50,51 (i.e. 3D vs. 2.0 mm), comparison of single and double plates n = 2 36,47 , identical study n = 1 23 and duplicated study n = 1 24 .…”

Three-Dimensional Osteosynthesis Plates for the Surgical Treatment of Mandibular Fractures

“…Usually, two plates are used if the fractures are anterior to mental foramen and one plate for fractures posterior to foramen 5 . The Champy technique is proposed as a semi-rigid fixation 6 . The use of 3D plates for the treatment of mandibular fractures was introduced by Farmand in 1992 7 .…”
