A classification scheme for periodontal and peri-implant diseases and conditions is necessary for clinicians to properly diagnose and treat patients as well as for scientists to investigate etiology, pathogenesis, natural history, and treatment of the diseases and conditions. This paper summarizes the proceedings of the World Workshop on the Classification of Periodontal and Peri-implant Diseases and Conditions. The workshop was co-sponsored by the American Academy of Periodontology (AAP) and the European Federation of Periodontology (EFP) and included expert participants from all over the world. Planning for the conference, which was held in Chicago on November 9 to 11, 2017, began in early 2015. An organizing committee from the AAP and EFP commissioned 19 review papers and four consensus reports covering relevant areas in periodontology and implant dentistry. The authors were charged with updating the 1999 classification of periodontal diseases and conditions and developing a similar scheme for peri-implant diseases and conditions. Reviewers and workgroups were also asked to establish pertinent case definitions and to provide diagnostic criteria to aid clinicians in the use of the new classification. All findings and recommendations of the workshop were agreed to by consensus. This introductory paper presents an overview for the new classification of periodontal and peri-implant diseases and conditions, along with a condensed scheme for each of four workgroup sections, but readers are directed to the pertinent consensus reports and review papers for a thorough discussion of the rationale, criteria, and interpretation of the proposed classification. Changes to the 1999 classification are highlighted and discussed. Although the intent of the workshop was to base classification on the strongest available scientific evidence, lower level evidence and expert opinion were inevitably used whenever sufficient research data were unavailable. The scope of this workshop was to align and update the classification scheme to the current understanding of periodontal and peri-implant diseases and conditions. This introductory overview presents the schematic tables for the new classification of periodontal and peri-implant diseases and conditions and briefly highlights changes made to the 1999 classification. It cannot present the wealth of information included in the reviews, case definition papers, and consensus reports that has guided the development of the new classification, and reference to the consensus and case definition papers is necessary to provide a thorough understanding of its use for either case management or scientific investigation. Therefore, it is strongly recommended that the reader use this overview as an introduction to these subjects. Accessing this publication online will allow the reader to use the links in this overview and the tables to view the source papers (Table 1).
牙周病和种植体周围病的分类方案对于临床医生正确诊断和治疗患者以及科学家研究疾病和病况的病因、发病机制、自然史和治疗方法是必要的。本文总结了牙周病和种植体周围病分类世界研讨会的会议记录。该研讨会由美国牙周病学会（AAP）和欧洲牙周病学会（EFP）共同主办，来自世界各地的专家参加了会议。会议于 2017 年 11 月 9 日至 11 日在芝加哥举行，会议的筹备工作于 2015 年初开始。AAP 和 EFP 的一个组织委员会委托撰写了 19 篇综述文章和 4 篇共识报告，涵盖了牙周病和种植体牙科的相关领域。作者的任务是更新 1999 年牙周病和病况分类，并为种植体周围病和病况制定类似的方案。审稿人和工作组还被要求确定相关的病例定义，并提供诊断标准，以帮助临床医生使用新的分类。研讨会的所有发现和建议都经过一致同意。本文介绍了牙周病和种植体周围病的新分类概述，以及四个工作组部分的浓缩方案，但读者可参考相关的共识报告和综述文章，以全面讨论拟议分类的原理、标准和解释。强调并讨论了对 1999 年分类的更改。尽管研讨会的目的是基于现有最有力的科学证据进行分类，但只要缺乏足够的研究数据，就不可避免地使用较低水平的证据和专家意见。本次研讨会的范围是使分类方案与牙周病和种植体周围病的当前理解保持一致和更新。本文介绍了牙周病和种植体周围病新分类的示意图表，并简要介绍了对 1999 年分类的更改。它无法提供包含在综述、病例定义论文和共识报告中的丰富信息，这些信息指导了新分类的制定，因此，有必要参考共识和病例定义论文，以充分理解其用于病例管理或科学研究的用途。因此，强烈建议读者将本文作为这些主题的介绍。在线访问本出版物将允许读者使用本文概述中的链接和表格查看源论文（表 1）。
