AbstractObjectives:-The objective of this retrospective study is to evaluate the skeletal maxillomandibular changes after orthodontic treatment through Steiner’s cephalometric analysis. Materials & Methods:-Pre and post treatment cephalometric radiographs of 50 orthodontic patients were used for this retrospective study, where they have been divided into two groups (25 Extraction and 25 Non extraction cases). Evaluation of Steiners - SNA, SNB and ANB angles in both the Pre and Post treatment cephalogram were done. Statistics:The data was tabulated and computed using SPSS software version 21.0.The Pre and Post cephalometric parameter were analysed through paired sample T tests, by calculating the mean difference, Standard deviation and Standard error and paired differences. Results:-ANB angle showed a decrease of 1.12° among the patients treated with extraction procedures, and the ANB angle showed increase of 0.2° among patients treated with non extraction procedures.
Conclusion:- The result of the above study suggested that the ANB reduced in patients who underwent extraction orthodontic therapy and the patients treated as non extraction did not show much significant difference
