Resumen
Introduction: The performance of orthodontic treatments is not only limited to dental changes, but also implies changes in the patient's soft tissues, thus generating changes in the smile and in turn, has an impact on facial aesthetics. The approach towards the correct realization of the initial facial diagnoses leads to the selection of correct reference planes for each population. Multiple lines have been used to determine the lip position in both research and clinical practice such as Rickets, Burstone, Suscher, Steiner; Previous research has evaluated the level of consistency and sensitivity among these as they are prone to high variability by having soft tissue points that are not stable over time. Objectives: To establish the degree of agreement between the measurements of Rickets, Burstone and Spradley to determine the labial position in digital profile radiographs in the Nemoceph software of patients from a radiological center in Bucaramanga, Colombia. Materials and methods: Digital radiographs of a radiological center of Bucaramanga taken in a natural position of the head included in the Nemoceph software for determination of cephalometric points in order to build the Rickets, Spradley and Burstone planes. Taking measurements and diagnoses for analysis of variables and comparison of them. Results: There is no agreement between the diagnoses given by each of the reference lines, probably associated with the significant and continuous variation of the anatomical soft tissue reference points. Conclusions: There is a high variability in all measures in terms of concordance, so the use of a single measure to diagnose the position of the lips is not reliable. The Spradley line is presented as a slightly more reliable option as it does not depend on variable anatomical structures and only an x-ray is taken in a natural position of the head.
