Primary stabilityis not sufficientin less contact area between the implant and bone, the healing process because will be disrupted due to micro-motions and fibrous tissue affects osseointegration.
We implemented an in vitro experimental study of total 135 XiVE® implants were inserted in 22.5 bovine cow ribs with bone quality similar to a type IV human bone. Each rib end received a group of three different implant lengths, which were 8mm, 13mm and 15mm and had the same diameter 3.8mm. Immediately after the implant placement, its primary stability was measured using Osstell Mentor equipment. ANOVA Tukey's honest to test the significant difference were performed for data analysis between the resonance measures of the different lengths of implants. Statistical significance was assessed at a level < 0.05.
A total of 45 implants were inserted for each length at cortical bone level. A significant difference between the three groups in favor of implant with 15mm length group ( = 0.000).
Increasing dental implant length is considered to play a fundamental role in increasing dental implant primary stability, even in poor bone quality, through controlling the bone preparation process. Dental implants, primary stability, resonance frequency analysis.
种植体与骨之间接触面积较小时，初期稳定性不足，愈合过程会因微动和纤维组织而受到干扰，进而影响骨整合。
我们开展了一项体外实验研究，将总共135颗XiVE®种植体植入22.5根牛肋骨中，这些牛肋骨的骨质与IV型人类骨质相似。每根肋骨末端植入一组三种不同长度的种植体，分别为8mm、13mm和15mm，直径均为3.8mm。种植体植入后立即使用Osstell Mentor设备测量其初期稳定性。采用方差分析中的Tukey诚实检验对不同长度种植体的共振测量数据进行分析，以检验显著差异。显著性水平设定为<0.05。
在皮质骨水平，每种长度的种植体各植入45颗。三组之间存在显著差异，15mm长度组的种植体更具优势（P = 0.000）。
通过控制骨预备过程，增加牙种植体长度被认为在提高牙种植体初期稳定性方面起着重要作用，即使在骨质较差的情况下也是如此。牙种植体、初期稳定性、共振频率分析。
