Dentists often encounter patients with missing or malformed teeth. The maxillary lateral incisor is the second most common congenitally absent tooth. There are three treatment options that exist for replacing missing lateral incisors. They include canine substitution, a tooth-supported restoration, or a single-tooth implant. Selecting the appropriate option depends on the malocclusion, specific space requirements, tooth-size relationship, and size and shape of the canine. The ideal treatment is the most conservative option that satisfies individual esthetic and functional requirements. Often the ideal option is canine substitution. Although the orthodontist positions the canine in the most esthetic and functional location, the restorative dentist often needs to place a porcelain veneer or crown to re-create normal lateral incisor shape and color. This article closely examines patient selection and illustrates the importance of interdisciplinary treatment planning to achieve optimal esthetics. It is the first in a three-part series discussing the three treatment alternatives for replacing missing lateral incisors.
Patients with congenitally missing lateral incisors often raise difficult treatment planning issues. Therefore, to produce the most predictable esthetic results, it is important to choose the treatment that will best address the initial diagnosis. This article is the first in a three-part series that describes the different treatments available for patients with congenitally missing lateral incisors. This first article focuses on canine substitution as a method of tooth replacement for these missing teeth. The general dentist will learn to evaluate specific patient selection criteria and determine whether canine substitution is an appropriate treatment alternative for replacing missing lateral incisors. The orthodontist will understand how to position the canines to satisfy functional requirements and achieve proper esthetics. Finally, the importance of interdisciplinary team treatment planning is emphasized as a requirement for achieving optimal final esthetics.
牙医经常会遇到牙齿缺失或畸形的患者。上颌侧切牙是第二常见的先天性缺失牙。对于缺失的侧切牙，有三种治疗选择。它们包括尖牙替代、牙支持修复或单颗牙种植。选择合适的治疗方案取决于错颌畸形、特定的间隙要求、牙齿大小关系以及尖牙的大小和形状。理想的治疗方法是最保守且能满足个体美观和功能需求的方案。通常理想的选择是尖牙替代。尽管正畸医生将尖牙放置在最美观和功能最佳的位置，但修复牙医通常需要放置瓷贴面或牙冠以重塑正常侧切牙的形状和颜色。本文仔细研究了患者选择，并阐述了跨学科治疗计划对于实现最佳美观效果的重要性。这是一个由三篇文章组成的系列中的第一篇，讨论了替代缺失侧切牙的三种治疗方案。
先天性侧切牙缺失的患者常常会引发复杂的治疗计划问题。因此，为了获得最可预测的美观效果，选择最能解决初始诊断问题的治疗方法很重要。本文是一个由三篇文章组成的系列中的第一篇，描述了针对先天性侧切牙缺失患者的不同治疗方法。第一篇文章重点介绍尖牙替代作为这些缺失牙的一种牙齿替代方法。全科牙医将学会评估特定的患者选择标准，并确定尖牙替代是否是替代缺失侧切牙的合适治疗方案。正畸医生将了解如何定位尖牙以满足功能需求并实现适当的美观效果。最后，强调跨学科团队治疗计划对于实现最佳最终美观效果的重要性。
