PURPOSE
The purpose of this study was to evaluate and compare the strain developed in D2 and D3 types of bones on vertical loading by platform switch implants of different diameters.
MATERIALS AND METHODS
Implants of diameters 3.25 mm, 4.2 mm, and 5.0 mm and of length 11.5 mm were taken and placed each on D2 and D3 bone models. Strain gauges were attached on the buccal and the lingual sides on each of these samples, and a vertical load of 190N was placed on the samples. The strain was recorded using a data logger. The data obtained was analysed using one-way ANOVA and post hoc Tukey test.
RESULTS
In D2 and D3 bone models, 3.25 mm significantly showed greater bone strain values. The buccal side strain was higher irrespective of the implant diameter and density of bone.
CONCLUSION
Within the limitations of the study, it may be concluded that the narrow diameter implant produces greater strain than 4.2 and 5.0 mm diameter implants, respectively. The buccal side consistently produced higher bone strain values.
目的
本研究的目的是评估和比较不同直径的平台转换种植体在垂直加载时D2和D3型骨中产生的应变。
材料与方法
选取直径为3.25mm、4.2mm和5.0mm、长度为11.5mm的种植体，分别放置在D2和D3骨模型上。在每个样本的颊侧和舌侧粘贴应变片，并对样本施加190N的垂直载荷。使用数据记录器记录应变。使用单因素方差分析和事后Tukey检验对获得的数据进行分析。
结果
在D2和D3骨模型中，3.25mm的种植体显著显示出更大的骨应变值。无论种植体直径和骨密度如何，颊侧应变均较高。
结论
在本研究的局限性内，可以得出结论，窄直径种植体分别比直径为4.2mm和5.0mm的种植体产生更大的应变。颊侧始终产生较高的骨应变值。
