Purpose: This study aimed at assessing the radiographic consequences of implants supporting mandibular overdenture. Two implants located in expanded anterior– knife-edge ridges with crest ridge-splitting, bone graft, membrane placement followed by laser application. The anterior implants were compared to posterior ones implanted in unexpanded ridges with no modifications. Materials and methods: Twenty completely-edentate patients had anterior -knife-edge mandibles, two implants were received in the 1st premolar areas without ridgeexpansion or further alterations (Group I; control group). Another two implants (lateral-incisor areas) were placed. Ridge-expansion, bone graft, low-level laser therapy LLLT and membrane placement were all accomplished (Group II; test group). 6 months following placement of implants, Locator attachments were used to connect the mandibular overdentures to implants. Radiographic (Vertical bone loss; VBL and Horizontal bone loss; HBL) parameters were then respectively recorded at: overdentures delivery (baseline, T0), 6 months (T6), and 12 months (T12). Results: For each group, insignificant differences in HBL between observations were noted. Whereas, For Group I, VBL significantly increased (T6 to T12). Howbeit, insignificant differences in VBL and HBL among groups were revealed. Conclusion: Within this study limitation, mandibular knife-edge ridge expansion along with concurrent implants placement exhibited comparable radiographic outcomes to those implanted in unexpanded ridges. Yet, ridge-expansion together with LLLT seems advantageous respecting VBL.

Such treatment confers improved retention and stability, masticatory performance, quality of life, patient satisfaction coupled with the cost compared to conventional dentures (1, 2) .

目的:本研究旨在评估种植体支持下颌覆盖义齿的放射学后果。两个种植体位于扩展的前刀口嵴，嵴分裂，骨移植，膜放置，然后激光应用。将前牙种植体与后牙种植体进行比较。材料和方法:20例完全无牙患者为前刀口下颌骨，2例在第一前磨牙区种植，无嵴扩张或进一步改变(组I;对照组)。另外放置两个种植体(侧切牙区域)。嵴扩张、骨移植、低水平激光治疗LLLT和膜放置均完成(II组;测试组)。种植体放置6个月后，使用Locator附着体将下颌覆盖义齿与种植体连接。x线摄影(垂直骨丢失;VBL与水平骨丢失;然后分别记录覆盖义齿交付(基线，T0)， 6个月(T6)和12个月(T12)时HBL参数。结果:各组间HBL差异无统计学意义。而第1组VBL明显增高(T6 ~ T12)。各组间VBL、HBL差异无统计学意义。结论:在本研究的限制范围内，下颌刀缘脊扩展与种植体同时放置显示出与未扩展脊植入的放射学结果相当。然而，脊状扩展与LLLT在VBL方面似乎是有利的。Denewar BA *1, El Waseef FA 2, El Mekawy N 3, Ahmed S.Salem 4, Hegazy SA 51埃及曼苏拉大学口腔医学院口腔修复系助理讲师，2埃及曼苏拉大学口腔医学院口腔修复系副教授，3埃及曼苏拉大学口腔医学院口腔修复系教授，4埃及曼苏拉大学口腔医学院口腔外科副教授，4埃及曼苏拉大学口腔医学院口腔外科副教授，5埃及曼苏拉大学牙科学院口腔修复系教授。提交:2021年9月24日接受:2021年9月30日发布:2021年10月30日www.ijsrm.humanjournals.com引文来源:Denewar BA et al。Ijsrm。人,2021;Vol. 19(4): 112-124。引言:显然，骨整合种植体支持覆盖义齿是一种成功的治疗方法，用于治疗与下颌牙槽嵴萎缩相关的患者的义齿问题。与传统义齿相比，这种治疗可以改善固位和稳定性、咀嚼性能、生活质量、患者满意度以及成本(1,2)。附着体是真正用来固定种植覆盖义齿的。有趣的是，各种系统都很容易得到。其中，Locator成为一种越来越受欢迎的附着系统，可用于独立的非夹板植入物。该系统被归类为通用铰链弹性覆盖义齿附着体内种植体。定位附件是常见的地方低姿态附件，此外，它可以抵消角度校正高达40◦。简单地说，脊裂技术导致侧脊扩张并通过纵向截骨创造新的种植床。这将允许颊(唇)皮质向外侧定位，最终在颊和舌皮质板之间形成一个空间。如果需要，这个空间将被填入骨内植入物和移植物材料。该技术有利于立即同时植入，具有最小的技术并发症，避免供体部位的发病率，并显著减少治疗时间。低水平激光治疗(LLLT)对骨再生的有效性目前受到关注，因为它可以改善血管化和增强胶原蛋白合成。它能调节炎症，加速成纤维细胞增殖，促进伤口愈合。此外，LLLT还能刺激骨干细胞并加速其修复过程。显然，即刻植入已经变得越来越流行，并且被许多患者更好地接受。它避免了第二次手术的需要，通过手术后立即加载植入物来简化配置。本研究旨在评估和比较种植体支持下颌覆盖义齿的放射学结果;两个放置在下颌骨扩展的刀口脊上，进行脊裂，骨移植物加上膜放置，然后激光应用，那些植入物放置在未扩展的脊上。原假设为不存在www.ijsrm.humanjournals.com引文:Denewar BA et al。Ijsrm。人,2021;Vol. 19(4): 112-124。 在所有时间间隔内，植入物放置在扩展和未扩展脊上的放射学结果存在显著差异。材料与方法
