Impacted teeth: Their place is in the dental arch

ABSTRACT The starting point for the treatment of unerupted teeth should consider the fact that, biologically, the pericoronal follicle maintains the ability to release EGF and other mediators responsible for eruption over time. The eruptive events may be guided and directed, so that teeth may occupy the space prepared to receive them in the dental arch, as showed in the case presented to evidence the following principle to be considered in these cases: “Regardless of the position of an unerupted tooth, it may be biologically directed to its place in the dental arch. The orthodontist should apply a mechanics to guide it and park it at its site.”

摘要 未萌出牙的治疗起始应考量如下生物学事实：牙冠周囊（pericoronal follicle）可持续释放表皮生长因子（EGF）及其他参与牙齿萌出过程的介质。牙齿萌出进程可被引导与调控，使其能够精准占据牙弓内预先预留的萌出间隙，正如本病例所呈现，用以佐证此类病例需遵循的下述核心原则：“无论未萌出牙的初始位置如何，其均可通过生物学机制导向至牙弓内的正常萌出位点。正畸医师应采用矫治力学手段引导该牙齿，并将其稳固安置于目标位点。”
