There are several treatment options for patients with coronal fractures, subgingival caries perforations, and root resorption. Frequently, forced eruption is not considered, although in many cases of single-rooted teeth, forced eruption is the "gold standard" for producing an esthetic result without jeopardizing periodontal support for adjacent teeth. Sufficient tooth length, achieved through forced eruption, ensures the periodontal health of the "biologic width" and crown margin and thus a successful restorative outcome.
对于患有冠折、龈下龋穿孔和牙根吸收的患者,有多种治疗选择。通常,不考虑进行正畸牵引,尽管在许多单根牙病例中,正畸牵引是在不危及邻牙牙周支持的情况下获得美观效果的“金标准”。通过正畸牵引获得足够的牙冠长度,可确保“生物学宽度”和冠边缘的牙周健康,从而实现成功的修复效果。
