下颌骨缺损的修复重建对提高患者的生存质量具有重要意义。下颌骨重建的目的不仅仅是为了恢复颌骨的连续性、维持患者正常的容貌形态,而且要恢复患者的咀嚼、吞咽、语言等正常生理功能,达到牙-颌-肌肉-神经反射的协调及功能统一,即功能性重建。本文回顾了下颌骨缺损修复重建的现状和研究进展,包括下颌骨修复重建的原则、常见的下颌骨缺损的修复重建方法、下颌骨功能性重建的若干问题、牵张成骨及组织工程在下颌骨修复重建中的应用等。  相似文献

由于整复外科的发展,因肿瘤切除术后或创伤等原因造成的下颌骨缺损,临床上采用自体游离骨移植,自体骨肌瓣移植修复等均可成功地恢复下颌骨的连续性,并获得较为理想的形态恢复。但在口腔功能的重建,尤其在咀嚼功能的重建方面,往往很难达到满意的效果。本文较系统地复习了下颌骨缺损移植修复后牙列重建的有关文献,着重介绍了在移植骨上行种植牙修复的方法:即small氏U型夹板修复法和Branemark氏骨整合性种植体修复法及其相应的应用指征。为了在移植骨上行种植牙修复并获得高的成功率,下颌骨缺损的骨移植修复宜选用带旋髂深动静脉的复合髂骨肌皮瓣。文中也介绍了移植骨上行种植体牙列重建的临床应用情况,指出种植体牙列重建对恢复下颌骨缺损行植骨修复后患者的咀嚼功能重建,外形和语言功能的改善均具有良好的应用价值,是提高该患者生存质量的一种有效手段,并为功能外科的开展开辟了一条非常有意义的道路。  相似文献

目的 探讨应用腓骨瓣及CAD/CAM技术修复大面积下颌骨缺损的经验。方法 根据16例患者下颌骨缺损的部位和特征,通过螺旋CT扫描获取缺损区的数据,在软件中应用CAD/CAM技术模拟下颌骨切除及重建手术,利用快速成型机加工制作出实物模型,依据模型对腓骨进行塑形、钛板重建,恢复下颌骨的形态和功能。结果 CAD/CAM技术的应用使术中截骨、腓骨塑形、定位速度明显加快;术后患者面部外形基本对称,影像学检查显示下颌骨缺损区的重建形态及固位良好;无严重并发症。结论 腓骨瓣联合CAD/CAM技术重建下颌骨缺损,能够明显缩短手术时间,提高手术质量,保证手术效果,是值得推广的重建下颌骨缺损的理想方法。  相似文献

目的:对重建下颌骨缺损的血管化腓骨肌瓣制备和塑形方法进行外科改良。方法:(1)非驱血状态下于大腿安放电子止血带加压后直接进行腓骨组织瓣制备;(2)暴露腓骨后,在待取腓骨的上下端各截除小段骨再实施腓骨的带血管制备;(3)对腓骨施行阶梯状截骨塑形。结果:7例腓骨瓣制备和术后出血(渗血)少,制备时间缩短。术后均一期成活,未发生感染或其他并发症。骨段固定稳固,下颌轮廓和外形良好。结论:(1)非驱血制备腓骨瓣不增加出血机会,反而减少出血机会,简化手术操作;(2)在待取腓骨的上下端截除小段骨可以使待取腓骨段充分游离,便于带血管制备和减少损伤血管的机会;(3)阶梯形截骨塑形,既增加了骨断面的接触面积和稳定性,又避免了楔形切骨骨量的丧失。  相似文献

Purpose

The aim of this study was to investigate how the physical variables of fibular reconstructed mandibles with dental implants affects the relative bite force in oral cancer patients.

Materials and methods

Over 7 years of follow-up, 13 oral cancer patients were enrolled who included 51 successful implants in the fibular flap. The tactile sensor analyzer evaluated the bite force. The crown-implant ratio, fibular, and rehabilitated dental length were measured using radiographic images. Linear regression was used to analyze the bite force related to the variables of the implants in the fibular reconstructed mandible.

Results

Even when the results showed no statistical significance (P > 0.05), increasing the crown-implant ratio, length of the fibular flap, and implant prosthetic reconstructed dentition had a tendency to decrease the bite force (estimate from ?0.08% to ?4.27%); there was a positive trend of occlusal force and the length of rehabilitative dentition compared with the dental antagonist (estimate = 6.95).

Conclusion

In this study, the crown-implant ratio, implant dentition, and fibular flap length revealed no significant impact on the bite force or implant success in oral cancer patients; however, a trend to weaken the bite force was suggested once the numerical values of these variables increased.  相似文献

Background

Vascularized fibular flaps are considered the gold standard for the reconstruction of segmental defects in the mandible. This review compares the complication and success rates of these techniques between primary and secondary reconstruction, as well as between lateral and antero-lateral defects.

Type of studies reviewed

A systematic review and meta-analysis were conducted according to PRISMA protocol and the Cochrane Handbook for Systematic Reviews of Interventions. The authors performed an independent comprehensive search using PubMed, Ovid MEDLINE, Web of Science, the Cochrane Central Register of Controlled Trials, ClinicalTrials.gov and COS Conference Papers Index according to established inclusion and exclusion criteria. The methodological index for nonrandomized studies (MINORS) was used to assess the quality of the included studies. Meta-analysis was conducted to compare the type of reconstruction and location of the defect.

Results

Seventy-eight studies, involving 2461 patients, were eligible. 83.7% of the included patient received primary reconstruction with vascularized fibular flap. The overall flap success rate was 93%. There was improvement in MINORS quality score over time with positive correlation with the publication year (r = 0.5549, P < 0.0001, CI 0.3693 to 0.6979). Meta-analysis indicated no significant association in flap success between primary and secondary reconstruction, or lateral and antero-lateral defects.

Conclusion

Based on the available studies, this review found no evidence of difference in success or complication rates between primary and secondary reconstruction or between lateral and anterolateral defects. High-quality clinical studies are required to analyze the outcome of these techniques, especially regarding the impact of chemotherapy, radiation therapy, implant-supported dental prostheses, and preoperative planning, on the outcome of reconstruction.  相似文献

Computer-aided design/manufacturing (CAD/CAM) is now widely used, but whether it can help to overcome complications in mandibular reconstruction and accelerate dental implantation is still a matter for debate. Therefore, we aimed to evaluate the benefits of this technique using vascularized iliac crest or fibula flaps in mandibular reconstruction, with respect to the time between reconstruction and implantation, and the ratio of planned to inserted implants. We reviewed retrospectively the records of 54 patients who underwent mandibular reconstructions between 2012 and 2016, and included in our study the last 10 cases representing each of the following groups: iliac crest flap with CAD/CAM (Group 1); fibula flap with CAD/CAM (Group 2); and fibula flap without CAD/CAM (Group 3). Groups 1 (p = 0.045) and 2 (p = 0.034) showed significantly shorter delays when compared with Group 3. Significant differences in average counts of implants placed were also found between Group 1 and Groups 2 (p = 0.04) and 3 (p = 0.019). The ratio of planned to placed implants was highest in Group 1. The observed differences between Group 1 and Groups 2 (p = 0.04) and 3 (p = 0.019) were significant. Our results indicate an accelerating effect of CAD/CAM on graft consolidation and dental rehabilitation.  相似文献
