This article presents a methodology of a comprehensive score for assessment and monitoring of dental implant success from the peri-implant tissue perspective. It involves only standard and minimally invasive techniques accessible to general dental practices, without the need for special equipment.
The proposed score methodology combines existing consensual global knowledge regarding aspects of dental implant success with the standard examination tools accepted for regular recall assessment. The score is a sum of five three-grade parameters: bone level, peri-implant inflammation, amount of attached mucosa, tissues recession (ie, exposure of implant components to intraoral environment), and the horizontal buccal profile of the alveolar process. The name peri-implant tissue score (PITS) is derived from the intended primary use of monitoring the state of implants and the surrounding hard and soft tissues. With its emphasis on buccal-aspect tissues, the score is designed to aid the detection of early signs of tissues deterioration.
The use of the score is demonstrated on a sample pool of 869 retrospectively evaluated implants with airborne-particle-abraded, acid-etched surfaces with time in service from 0 to 12 years. The parameters constituting the score were statistically tested on correlation with a reference set of success criteria, on mutual cross-correlations, and on the invariance to the implants' time-in-service. The PITS demonstrated to be highly representative of the success criteria, offering a fine scale from 0 to 10, and reversibility.
The PITS withstood the tests. It responds to an existing need in the field, is widely accessible and inexpensive, and, thus, shows promise for use in general dental practice.
本文从种植体周围组织角度介绍一种用于评估和监测牙种植体成功的综合评分方法。该方法仅涉及一般牙科诊所可采用的标准且微创的技术，无需特殊设备。
所提出的评分方法将关于牙种植体成功方面的现有共识性整体知识与常规复诊评估所接受的标准检查工具相结合。该评分是五个三级参数的总和：骨水平、种植体周围炎症、附着黏膜量、组织退缩（即种植体部件暴露于口腔内环境）以及牙槽突的水平颊侧外形。种植体周围组织评分（PITS）这一名称源于其监测种植体及周围软硬组织状态的主要用途。由于该评分强调颊侧组织，旨在有助于检测组织恶化的早期迹象。
在一个包含869颗种植体的样本库中展示了该评分的应用，这些种植体为经空气颗粒喷砂、酸蚀处理的表面，使用时间从0至12年不等，对这些种植体进行了回顾性评估。对构成该评分的参数与一组成功标准参考值的相关性、相互间的交叉相关性以及种植体使用时间的不变性进行了统计学测试。PITS被证明高度代表成功标准，提供了从0到10的精细评分范围以及可逆性。
PITS通过了各项测试。它满足了该领域的现有需求，易于获取且成本低廉，因此在一般牙科实践中显示出应用前景。
