Absence of the maxillary lateral incisor creates an aesthetic problem which can be managed in various ways. The condition requires careful treatment planning and consideration of the options and outcomes following either space closure or prosthetic replacement. Recent developments in restorative dentistry have warranted a re-evaluation of the approach to this clinical situation. Factors relating both to the patient and the teeth, including the presentation of malocclusion and the effect on the occlusion must be considered. The objective of this study was to describe the etiology, prevalence and alternative treatment modalities for dental agenesis and to present a clinical case of agenesis of the maxillary lateral incisors treated by the closure of excessive spaces and canine re-anatomization. A clinical case is presented to illustrate the interdisciplinary approach between orthodontics and restorative dentistry for improved esthetic results. In this report, the treatment of a girl with a Class II malocclusion of molars and canines with missing maxillary lateral incisors and convex facial profile is shown. Treatment was successfully achieved and included the space closure of the areas corresponding to the missing upper lateral incisors, through movement of the canines and the posterior teeth to mesial by fixed appliances as well as the canines transformation in the maxillary lateral incisors. This is a 14-year follow-up case report involving orthodontics and restorative dentistry in which pretreatment, posttreatment, and long-term follow-up records for the patient are presented.
上颌侧切牙缺失会造成美观问题，对此可采用多种方法进行处理。这种情况需要仔细的治疗规划，并考虑间隙关闭或修复性替代后的各种选择和结果。修复牙科的最新进展使得有必要重新评估针对这种临床情况的治疗方法。必须考虑与患者和牙齿相关的因素，包括错牙合的表现以及对咬合的影响。本研究的目的是描述牙发育不全的病因、患病率和替代治疗方式，并呈现一例通过关闭过大间隙和犬齿重新塑形治疗上颌侧切牙发育不全的临床病例。现展示一个临床病例，以说明正畸学与修复牙科之间为改善美观效果而采取的多学科方法。在本报告中，展示了对一名患有磨牙和犬齿II类错牙合、上颌侧切牙缺失且面部轮廓凸出的女孩的治疗情况。治疗成功完成，包括通过固定矫治器将犬齿和后牙向近中移动来关闭对应于缺失上颌侧切牙区域的间隙，以及将犬齿转变为上颌侧切牙。这是一份涉及正畸学和修复牙科的14年随访病例报告，其中呈现了患者的治疗前、治疗后及长期随访记录。
