The exaggerated mesial eruption of the permanent first molar can result in the tooth becoming impacted, or the premature atypical resorption and exfoliation of the primary molar, with a resultant loss of space. A stainless steel crown with a distal guide plane was placed on a primary molar to correct the aberrant eruption angle of the permanent tooth. This procedure can be used successfully for both partially and totally tissue-impacted teeth, and is described in this report.
恒牙第一磨牙近中萌出过度可导致牙齿阻生，或乳牙过早出现非典型吸收和早失，进而导致间隙丧失。在一颗乳磨牙上放置带有远中导平面的不锈钢冠，以纠正恒牙异常的萌出角度。该方法可成功应用于部分和完全软组织阻生的牙齿，本报告对此进行了描述。
