The aim of this paper is to present a system for taking standardized photographs at different phases of treatment and making objective measurements based on these photographs, thus providing an objective comparison of various stages of therapy. This system situates a digital camera in a fixed relationship to stone casts of preselected clinical situations. After the photographs are imported to computer software, lines and points can be traced and then independently transferred from one picture to another. The technique makes it possible to compare the outcome of a certain procedure with a linear error < 0.1 mm. The system can be used to analyze, compare, and measure vertical changes of the soft tissue margins, thus allowing for an objective, reproducible evaluation. The ability to measure results is important not only for clinicians who are committed to increasing their knowledge and improving their clinical procedures, but also for researchers who aim to compare a situation before, during, and after treatment to determine the efficacy of different techniques.
本文的目的是介绍一种系统，该系统可在治疗的不同阶段拍摄标准化照片，并基于这些照片进行客观测量，从而对治疗的各个阶段进行客观比较。该系统将数码相机与预先选定临床情况的石膏模型建立固定关系。照片导入计算机软件后，可以绘制线条和标记点，然后独立地从一张图片转移到另一张图片。该技术能够以小于0.1毫米的线性误差比较特定程序的结果。该系统可用于分析、比较和测量软组织边缘的垂直变化，从而实现客观、可重复的评估。测量结果的能力不仅对致力于增加知识和改进临床程序的临床医生很重要，对于旨在比较治疗前、治疗期间和治疗后的情况以确定不同技术疗效的研究人员也很重要。
