The risk profile is displayed as a diagram on the left-hand side of the graphic by selecting the findings values and can be printed out as a PDF. The risk is assessed according to the traffic light system.

The vector diagram risk analysis (VDR) visualises the patient’s individual risk profile on the basis of disease characteristics that can make a statement about the applicability of UPS therapy (predictors). With the VDR, several predictors in a patient-specific constellation of findings can be easily visualised as a risk profile and compared with each other over the course of the recall. The risk assessment of the predictors is carried out according to the three risk levels low (green), medium (yellow) and high (red) for the three areas of periodontology, prosthetics and function [20,21,22,23,24]. Two of the five periodontological predictors, the maximum radiographic bone loss (BL, in per cent) and the age-related maximum radiographic bone loss (BL/A, BL in per cent divided by age in years) are recorded after evaluation of the OPTG. The findings of the other periodontological predictors, the bleeding after probing (BOP in per cent), the probing depths (PPD, number of teeth in per cent with PPD ≥4 mm) and the maximum clinical interdental attachment loss (CAL, in millimetres) are recorded clinically using the WHO probe. The prosthetic predictors record the degree of loosening (LG, number of teeth with LG ≥1), the number of missing teeth (F, number of missing teeth without consideration of wisdom teeth) and the Eichner classification (EK, without consideration of teeth with an LG ≥1). The Eichner classification is carried out separately for the implantological and dental prosthetic abutments (prosthetic classification) and for the occlusion, including prosthetics if applicable (occlusal classification). The occlusal classification is marked with an asterisk (*) in the vector diagram.

Performance monitoring in the form of a vector diagram can be helpful when evaluating the results from the patient’s subjective assessments of adherence, the assessment-relevant endpoints and the objective measurements using the UPS. In the Performance Monitor, the labels of the results are arranged on the outside of their vector beams and the patient-specific results themselves are arranged on the vector beam. The designations for the subjective assessments of the evaluation-relevant endpoints are marked in blue with their vector arrows, the designations for the subjective assessment of adherence are marked in green with their vector arrows and the designations for the objective measurements are marked in black with their vector arrows. Three colour areas red, yellow and blue are grouped eccentrically around the centre for easier visualisation of the result areas with low, red, medium, yellow and high, blue, performance. The patient-specific results are marked on the vector arrows according to the result areas specified in the diagram, which are shown circled in the diagram. The combination of all the markings ultimately results in the patient-specific performance profile.

The effectiveness of UPS therapy can be assumed if the performance profile is at least medium (yellow area in the vector diagram) and there is no indication for readjustment after the medical and dental risk-benefit analysis.
