Restoring the extensively damaged dentition has always been a difficult decision-making process for the dental practitioner. Decisions to restore these teeth were primarily based on the fact that "fixed" teeth are typically better functionally than "removable" teeth and better esthetically than "no" teeth. Prior to dental implants, restoring missing teeth and extensively damaged teeth utilizing traditional therapy such as crown lengthening, root hemisection/amputation, endodontic therapy, apical surgery, post and cores and splinting were the options available to our patients. These teeth typically required the expertise of additional specialist, however their prognosis and success rates were typically guarded at best. Presently, dental implant success rates have been clearly identified and documented in the literature which now questions the survivability and success rates of the traditional mode of therapy for extensively damaged teeth. This paper will attempt to review the dental literature for various traditional modes of therapy for restoring the extensively damaged to provide a consensus of their survivability to help the practitioner to present options and prognosis for their patients.
对于牙科医生来说，修复严重受损的牙列一直是一个艰难的决策过程。修复这些牙齿的决定主要基于这样一个事实，即“固定”牙齿在功能上通常比“可摘”牙齿更好，在美观上比“无”牙齿更好。在种植牙出现之前，利用传统治疗方法，如牙冠延长术、牙根半切术/截根术、根管治疗、根尖手术、桩核修复和夹板固定等，来修复缺失牙和严重受损牙，是我们为患者提供的选择。这些牙齿通常需要其他专科医生的专业知识，然而，它们的预后和成功率充其量也只是一般。目前，种植牙的成功率已在文献中得到明确认定和记录，这使得人们对传统治疗严重受损牙齿方法的生存率和成功率产生了质疑。本文将尝试回顾牙科文献中各种修复严重受损牙齿的传统治疗方法，以就其生存率达成共识，帮助医生为患者提供各种选择和预后情况。
