The intent of this paper is to demonstrate a clinical technique for the replacement of multiple missing anterior teeth in the presence of a mutilated ridge. It also reviews basic rules governing the replacement of multiple adjacent missing teeth. The two cases presented clearly demonstrate that multiple adjacent missing teeth can be esthetically restored and still preserve that which remains; teeth, periodontium and soft tissues. The long-term success or failure of prosthodontic restorations relies heavily upon careful consideration of esthetic and foundational requirements. A technique has been described which incorporates the benefits of both fixed and removable dentures to restore multiple missing teeth in the presence of a mutilated alveolar ridge. The first patient was treated approximately twenty years ago. The anterior teeth and alveolar ridge were lost due to an automobile accident. The entire labial alveolar ridge was lost to the base of the nasal spine, thereby making a simple six-unit anterior fixed partial denture a complex and difficult problem. The second patient was recently treated. This patient's alveolar ridge and buccal plate were destroyed by a horse's hoof, again making a restoration procedure a difficult one.
本文旨在展示一种在牙嵴残缺情况下替换多颗上前牙缺失的临床技术。本文还回顾了关于替换多颗相邻缺失牙的基本规则。所呈现的两个病例清楚地表明，多颗相邻缺失牙可以通过美学方式修复，同时仍保留剩余的牙齿、牙周组织和软组织。口腔修复体长期的成功或失败在很大程度上依赖于对美学和基础要求的仔细考量。本文描述了一种结合了固定义齿和可摘义齿优点的技术，用于在牙槽嵴残缺的情况下修复多颗缺失牙。第一位患者大约在二十年前接受治疗。由于一场车祸，其上前牙和牙槽嵴缺失。整个唇侧牙槽嵴缺失至鼻棘基部，因此制作一个简单的六单位上前牙固定局部义齿成为一个复杂且困难的问题。第二位患者是近期接受治疗的。该患者的牙槽嵴和颊板被马蹄破坏，同样使修复过程变得困难。
