horizontal impaction

基本解釋

Most food impaction happened in the interproximal of molars. The impaction types were mainly hybrid and vertical impaction, and only 9.7% was horizontal impaction.
嵌塞部位以磨牙間隙為主，嵌塞類型以混合型和垂直型嵌塞為主，水平型所占比例為9.7%。
To study the impaction, two fundamental problems have to be solved first. One is the simplified method for simulating an urban regional seepage field with 2D horizontal seepage FEM.
為分析研究這種影響，必須解決城區(qū)滲流場(chǎng)簡(jiǎn)化計(jì)算和地層參數(shù)插值分析2個(gè)基本問(wèn)題。
Objective:To investigate the superiority by using high speed air turbine drill in extraction of impacted mandibular teeth, especially in low mesioangular impaction and horizontal impaction.
目的：探討高速渦輪機(jī)在輔助拔牙，特別是在下頜近中低位及水平位阻生牙的拔除中的優(yōu)越性。
