“…Navarro et al [ 34 ] selected ninety patients with Class I and Class II malocclusions for their study, with subgroups divided into horizontal, vertical and balanced growth patterns. The changes of 1-NB before and after treatment considering the values proposed by the Steiner analysis were examined thoroughly.…”

Background The fundamental part of every successful orthodontic treatment is the detailed treatment planning including a precise determination of the virtual treatment objective (VTO) while considering the biological and anatomical limits. The aim of this study is to investigate and to compare the feasibility of the established reference values before and after orthodontic treatment and to determine the usefulness of this parameters as guidance for the sagittal anterior, sagittal posterior and transverse biological boundaries. Materials and methods Thirty-two patients aged 9 to 18 years (12 male and 20 female) with all permanent teeth present were randomly selected for orthodontic treatment with fixed multibracket appliance regardless of the potential malocclusion. The parameters 6-PTV, 1-NB [mm] and the WALA ridge were set for the identification of the transverse, sagittal anterior and sagittal posterior tooth position. The measurements were carried out at the beginning (T0) and at the end (T1) of the orthodontic treatment. They were set in relation with their individual threshold values (G). After the results of the measurements were conducted using the software OnyxCeph3TM (version 3.2.185 (505), Image Instruments GmbH, Chemnitz, DE), they were statistically calculated in the software RStudio (2022.12.0 Build 353 © 2009–2022 Posit Software PBC). Results Among the 32 patients, the mean pre- and post-treatment changes measured through the three parameters in relation to the individual reference values were statistically significant (p < 0.01). The mean values for 6-PTV, 1-NB and the WALA ridge amounted 15.37 mm, 2.56 mm and 4.23 mm at the beginning of the treatment, while after the treatment the measured values amounted 20.31 mm, 2.4 mm and 5.55 mm. These measurements combined with the statistical analysis of the changes of WALA ridge (T0, T1) confirmed that the teeth have been successfully uprighted and aligned. Furthermore, the maxillary first molars have been moved slightly mesially, as proven by the changes in 6-PTV, without certainty as to whether bodily movement or mesial tipping took place. Additionally, the lower incisors have been protruded, slightly exceeding the individual threshold values. Conclusion The parameters investigated provide a suitable assessment tool for recording the limits of the sagittal posterior, the sagittal anterior and the transverse dimension.

“…Analisis Steiner adalah analisis yang paling populer dalam menentukan rencana perawatan ortodonti, karena analisis ini dianggap mudah dan cepat dalam pelaksanaanya. 16 Analisis Steiner berfokus pada pada hubungan antara sudut ANB dan sudut U1-NA/L1-NB, juga pada posisi tepi insisal dari mandibular dan maksila yang berelasi dengan garis NA dan NB. 17 Analisis Steiner meliputi posisi dan inklinasi gigi insisif terhadap rahang serta posisi rahang terhadap basis cranium.…”

Background: Cephalometric analysis is an important tool in the field of orthodontics. It is used to examine the growth and development of facial bones in treatment planning, and changes between before and after treatment in evaluation stage. Steiner's analysis uses angle dan distance measurements to determine the patient's skeletal position. Steiner's analysis includes the position and inclination of the incisors to the jaw and the position of the jaw to the cranial base. This study was thus carried out to describe the value of cephalometric parameter measurements of Deutro-Malay race patients aged 6-12 years using Steiner's analysis. Materials and Methods: This study is a descriptive observational method with a cross-sectional study design. Samples were taken from secondary data of cephalogram orthodontic patients RSGM FKG Usakti in 2017-2018. The analysis was carried out by measuring 11 Steiner's analysis parameters, namely: SNA, SNB, SND, ANB, Go-Gn to SN, U1-NA, L1-NB, U1-L1, Occl-SN. Results: Based on Steiner's analysis, the cephalometric mean value of RSGM FKG Usakti orthodontic patients was SNA of 80.80; SNB of 76.60; SND of 72.990; ANB of 4,240; Go-Gn to SN is 36.80; U1-NA is 26,920 and 3,93 mm; L1-NB of 32.10 and 5.98 mm; U1-L1 of 116,890; Occl-SN is 20,680. Conclusions: Malay Deutro Race has a tendency for class II, skeletal class II malocclusion, retrusive symphysis, less developed horizontal growth patterns, and incisive proclination.

Assessing the predictability of ANB, 1-NB, P-NB and 1-NA measurements on Steiner cephalometric analysis

Abstract: The limitations of the estimates of the measures do not invalidate its clinical or teaching use, if aware of its deficiencies, the analysis can be used with restrictions.
