This study aimed to overview and collect the current trends and techniques in managing maxillary impacted canines by retrieving recent literature, in a chronological manner from the prevention to the very late stages of treatment in adults.
We performed a review on the recent literature regarding the current trends on the management of impacted canines. We have researched various types of available articles such as clinical trials and case presentations, meta- and systematic analyses, and literature reviews focusing on clinical management of impacted canines and their outcome evaluations. We adhered to those articles published within the last decade with a focus on treatment planning for impacted and displaced canines.
Depending on the diagnosis and its timing of it, a maxillary impacted canine can be managed by either prevention or interception, surgical opening followed by autonomous eruption or orthodontically traction, autotransplantation, and at last by removal and space closure. These techniques are elaborated one by one according to the age and severity of the diagnosis.
Impaction of the canines is a manageable abnormality which is highly dependent on the timing and localization of the displaced tooth. Early detection will give the upper hand to orthodontists to engage by either prevention through extraction of deciduous canines or intercepting via assistant devices to create more space. According to the clinical situation, open or closed surgical uncovering might be required to bond an attachment. However, generally, those techniques did not show any significant clinical distinction in the outcome assessments.
These approaches are highly technique sensitive and require collaborations with other specialties. Proper diagnosis and prognosis assessment are necessary before making any decision to bring an impacted canine in alignment.
本研究旨在通过按时间顺序检索近期文献,概述并收集成人上颌埋伏尖牙从预防到治疗后期的当前治疗趋势和技术。
我们对近期有关埋伏尖牙治疗当前趋势的文献进行了综述。我们研究了各种可用的文章类型,如临床试验和病例报告、荟萃分析和系统评价,以及专注于埋伏尖牙临床管理及其结果评估的文献综述。我们坚持使用过去十年内发表的文章,重点关注埋伏和移位尖牙的治疗计划。
根据诊断及其时机,上颌埋伏尖牙可通过预防或阻断、手术开窗后自行萌出或正畸牵引、自体移植,最后通过拔除和关闭间隙来处理。这些技术根据诊断的年龄和严重程度逐一详细阐述。
尖牙埋伏是一种可处理的异常情况,高度依赖于移位牙齿的时机和位置。早期发现将使正畸医生占据优势,可通过拔除乳牙进行预防或通过辅助装置进行阻断以创造更多空间。根据临床情况,可能需要进行开放或闭合手术暴露以粘结附件。然而,一般来说,这些技术在结果评估中没有显示出任何显著的临床差异。
这些方法对技术高度敏感,需要与其他专业协作。在决定使埋伏尖牙排齐之前,进行正确的诊断和预后评估是必要的。
