The purpose of the study was to analyze whether adequate fracture fixation can be achieved by three-dimensional (3D) stainless steel mini-plates its ease of placement, whether the patient can resume function early and to find out the need to do intermaxillary fixation.
In the prospective study, we treated 12 patients and 17 fractured sites using 3D mini-plates. Once fracture reduction was achieved temporary intermaxillary fixation (IMF) was done occlusion was achieved and the fractured segments were fixed using 3D plates either 4-holed or 6-holed of 2.5 mm thickness and 6-8 mm length screws. IMF was removed subsequently.
In none of the cases non-union or malocclusion was noted. Similarly except for 2 cases which had associated subcondylar fractures IMF was not done postoperatively. The patients were able to achieve function immediately with a reasonable level of success. The interincisal opening ranged from 18 to 23 mm in the first week to 40-56 mm after 1 month.
本研究的目的是分析三维(3D)不锈钢微型钢板能否实现充分的骨折固定,其放置是否容易,患者能否早期恢复功能,并确定是否需要进行颌间固定。
在这项前瞻性研究中,我们使用3D微型钢板治疗了12例患者和17个骨折部位。一旦实现骨折复位,就进行临时颌间固定(IMF),实现咬合,然后使用厚度为2.5毫米、长度为6 - 8毫米的4孔或6孔3D钢板固定骨折段。随后去除IMF。
在所有病例中均未发现骨不连或错牙合。同样,除了2例伴有髁突下骨折的病例外,术后未进行IMF。患者能够立即恢复功能,且取得了合理程度的成功。术后第一周切牙间开口度为18至23毫米,1个月后为40至56毫米。
