背景与目的:狭窄的牙槽嵴是牙列最佳康复的障碍。有几种复杂且侵入性的技术来应对山脊增加的困境,他们中的大多数表现出很低的可行性。因此,这项随机临床试验旨在评估极简岭增强(MRA)技术的有效性,与低水平激光治疗(LLLT)。材料与方法:选取20例患者(n=20),其中10个分配到测试组(MRALLLT),另外10个分配到对照组(MRA)。将大约10毫米的垂直切口放置在缺损的近旁,并在缺损的整个宽度上形成骨膜下袋。在测试现场,使用二极管激光器(AnARCFoxTM外科激光器810nm)递送LLLT(参数:100mW,在连续波模式下,每点60s的最大能量分布为6J/cm2),其次是移植物(G-移植物,SurgiwearTM,Shahjahanpur,印度)用骨移植载体沉积。对照位点没有用激光照射。结果:在两组中观察到>2mm的水平脊宽度增加。试验组和对照组的骨密度变化分别为-136±236.08HU和-44.30±180.89HU,分别。此外,试验组和对照组在这些参数方面没有统计学上的显著差异.结论:研究结果表明,MRA技术用于牙槽隆突相对简单可行。LLLT在该过程中的作用需要进一步阐明。
Background and Objective: A narrow alveolar ridge is an obstacle to optimal rehabilitation of the dentition. There are several complex and invasive techniques to counter the ridge augmentation dilemma, with most of them exhibiting low feasibility. Hence, this randomized clinical
trial aims to evaluate the effectiveness of a
Minimalistic Ridge Augmentation (MRA) technique, in conjunction with low-level laser therapy (LLLT). Materials and Methods: A total of 20 patients (n = 20) were selected, with 10 assigned to the test group (MRA+LLLT) and the other 10 to the control group (MRA). A vertical incision of approximately 10 mm was placed mesial to the defect and tunneled to create a subperiosteal pouch across the entire width of the defect. At the test sites, a diode laser (AnARC FoxTM Surgical Laser 810 nm) was used to deliver LLLT (parameters: 100 mW, with a maximum energy distribution of 6 J/cm2 in the continuous wave mode for 60 s per point) to the exposed bone surface inside the pouch, followed by graft (G-Graft, SurgiwearTM, Shahjahanpur, India) deposition with a bone graft carrier. The control sites were not irradiated with a laser. Results: A horizontal ridge width gain of >2 mm was observed in both groups. The changes in bone density for the test and control groups were -136 ± 236.08 HU and -44.30 ± 180.89 HU, respectively. Furthermore, there was no statistically significant difference between the test and control groups in these parameters. Conclusion: The
study findings reveal that the MRA technique is relatively simple and feasible for alveolar ridge augmentation. The role of LLLT in the process requires further elucidation.
