Canine deviation from its path of eruption is usually followed by either delayed or impaction of canine. One of the important and not so noticed reasons for canine displacement is formerly impacted central incisor. The difference in age of eruption of these two teeth is 4 years; however, the absence of maxillary incisor should be perceived with utmost conviction about impending canine displacement leading to its impaction as well. This case presents similar picture where composite, compound odontoma with respect to maxillary central incisor led to its impaction resulted in deviated path of eruption for erupting canine. This canine displacement to worsen prognosis ended up getting impacted if not dealt with cautiously in the later stages of occlusal development.
犬齿偏离萌出路径通常会导致犬齿萌出延迟或阻生。犬齿移位的一个重要但不太为人注意的原因是先前阻生的中切牙。这两颗牙齿的萌出年龄相差4岁;然而,上颌中切牙的缺失应被充分认识到,这极有可能导致犬齿移位并最终阻生。本病例呈现了类似的情况,即上颌中切牙处的复合性、混合性牙瘤导致其阻生,进而致使正在萌出的犬齿萌出路径偏离。如果在咬合发育的后期阶段不谨慎处理,这种犬齿移位会使预后恶化,最终导致犬齿阻生。
