【摘要】：目的:研究特發(fā)性髁突吸收(ICR)患者下頜骨錐體束CT(CBCT)的影像學(xué)特點(diǎn)。方法:選取ICR患者和正常志愿者各41例,應(yīng)用Invivo5軟件測(cè)量所有受試者下頜骨CBCT數(shù)據(jù)資料,并進(jìn)行統(tǒng)計(jì)學(xué)分析。結(jié)果:ICR組與正常組間SNB、NP-FH、S-Go、S-Go/N-Me、Co-Go、H、ACo-PCo、PCo-Co、前斜角、S-Ar-Go、Co-Go-Me的差異有統(tǒng)計(jì)學(xué)意義(P0.05),而N-Me、Go-Me、S-Co、ACo-Co、后斜角無統(tǒng)計(jì)學(xué)意義(P0.05)。結(jié)論:ICR僅發(fā)生在髁突的頂端和前斜面,以髁突高度降低為主。ICR患者的下頜后縮由下頜骨后下旋轉(zhuǎn)引起,而非髁突后移所致。
[Abstract]:Objective: to study the imaging features of mandibular conical tract CTC CBCTs in patients with idiopathic condylar resorption (ICR). Methods: the mandibular CBCT data of all subjects were measured by Invivo5 software in 41 patients with ICR and 41 normal volunteers. Results between the two groups, there was a statistically significant difference between the two groups (SNBNP-FHHS-GoS-GoP / N-MeCoCo-Co-CoACo-CoA, S-Ar-Go-CoCo-Go-Me, N-MeGo-MeS-CoACo-CoCo-Co-Co.P 0.05). Conclusion the results showed that the incidence of Scole ICR was only at the apical and anterior oblique plane of the condyle, but there was no significant difference between the N-MeGo-MeS-CoACo-CoCo-Co.Conclusion the occurrence of Pregrade ICR was only at the apex of the condyle and the anterior oblique plane, and there was no significant difference in the posterior angle between the two groups. The mandibular retraction of ICR patients was caused by the posterior rotation of mandible, not by the backward movement of condyle.
