未经授权:骨折固定术,在当下,是经典的使用迷你盘子。固定下颌角骨折的钢板的位置和数量已经并且仍然在文献中进行了广泛的研究和报道。最近增加的是3D迷你板。
UNASSIGNED:比较和评估一个2.0mm钛3D微型板固定板(4-孔)和一个2.0mm钛4-孔微型板在下颌角骨折内固定中的生物力学行为。
UNASSIGNED:要测量断裂时的载荷,最大负载,分别使用3D微型钢板和常规微型钢板进行内固定的最大载荷下的位移。
未经授权:将五个干燥的尸体下颌骨分成10个半下颌骨。以下颌骨的角度对每个尸体下颌骨进行切片,以模拟不利的下颌角骨折。将获得的半可食性分为实验组(组1和组2),每组5个样品,分别镀有线性迷你板和3D迷你板。最大负载,断裂载荷,和最大载荷下的位移是唯一获得的比较参数。
UNASSIGNED:与记录平均最大载荷值为106.96N±23.86的3D微型板相比,常规微型板显示出更大的平均最大载荷值为174.93N±54.45。发现断裂载荷和最大载荷下的位移均微不足道。
UNASSIGNED:这项研究的结果表明,除最大载荷外,上述任何参数在统计学上都没有显着差异,两组之间进行评估。根据Champy的骨合成线,传统的线性微型板可以成功地用于提供令人满意的骨合成,并具有成本效益的决定性优势。
UNASSIGNED: Fracture fixation, in the present times, is classically done using mini plates. The position and number of plates to fixate a mandibular angle fracture have been and are still extensively researched and reported in the literature. A more recent addition is 3D mini plates.
UNASSIGNED: To compare and evaluate the biomechanical behavior of one 2.0 mm titanium 3D miniplate fixation plate (4- hole) and one 2.0 mm titanium 4-hole
miniplate in internal fixation of mandibular angle fractures.
UNASSIGNED: To measure load at break, maximum load, and displacement at maximal load for internal fixation done with 3D mini plates and conventional mini plates respectively.
UNASSIGNED: Five dry cadaveric mandibles were sectioned into 10 hemi-mandibles. Each cadaveric mandible was sectioned at the angle of mandible to simulate unfavorable mandibular angle fracture. The obtained hemimandible were divided into experimental groups (GROUP 1 and GROUP 2) with 5 samples in each group, plated with a linear miniplate and 3D
miniplate respectively. Maximal load, Load at break, and displacement at maximum load were the only obtained parameters for comparison.
UNASSIGNED: Conventional
miniplate showed greater mean maximum load values of 174.93 N±54.45 compared to 3D mini plates which recorded a mean maximum load value of 106.96 N ± 23.86. Load at break and displacement at maximum load were found to be both insignificant.
UNASSIGNED: The results in this
study showed statistically no significant difference with any of the above parameters except maximal load, between the two groups evaluated. Conventional linear
miniplate according to Champy\'s lines of osteosynthesis can be used successfully for providing satisfactory osteosynthesis with the definitive advantage of cost-effectiveness.
