In the diagnosis of the angle of the upper incisor, the cephalometric technique in Jaraback differs from that used in the Ricketts cephalometric technique, as they use different planes, which may lead to differences in their interpretations. The objective of this study was to compare the differences in the interpretations of the Jaraback and Ricketts cephalometric techniques regarding skeletal class I to determine the angulation of the upper incisor. The sample consisted of 30 cephalometric radiographs taken from patients treated at the Wiener dental center, selected based on inclusion and exclusion criteria. The angle of the upper incisor was first measured using the Jaraback cephalometric technique, which takes the measurement from the most anterior point of the maxillary bone, called the anterior nasal spine (ENA), to the most posterior point of the maxillary bone, called the posterior nasal spine (ENP). These points are connected to form the palatal plane, which forms an angle with the upper incisor axis, and this is then measured. Next, using the Ricketts technique, the measurement is taken from the posteroinferior point of the occipital bone at the anterior margin of the foramen magnum, called Basion (Ba), to the anterior point of the frontonasal suture, called Nasion (Na). These points are connected to form the cranial base plane, which forms an angle with the upper incisor axis and is then measured. These two results were compared to determine if there was equality or variation. The study found no difference in the interpretation between the Jaraback and Ricketts cephalometric techniques for determining the upper incisor angle. The different positions of the upper incisor are very important in orthodontic diagnosis and treatment, as they help determine how much torque should be applied to the dental piece, thereby helping to decide the most effective prescription to be used in the treatment process.
