Abstract: Background and Aim: Modern procedures, such as maxillary arch distalization using mini - implants like infrazygomatic crest (IZC) implants, can yield improved outcomes. the purpose of this study was to compare the cephalometric parameters before and after treatment using IZC/buccal shelf (BS) screws and the traditional method of retraction. 7 Additionally, we aimed to evaluate the effectiveness of IZC screws in retracting teeth while preserving the arch length. Material and Methods: A split - mouth study was conducted with 20 patients at the Department of Orthodontics, NIMS dental college and hospital. The selection of cases was based on Class 2 malocclusion. Patients in the control group had class 2 malocclusion and willingly underwent extraction of their first premolar. IZC screws were utilized to facilitate distalization for the study group. Study models were created and radiographs of the individuals were taken six months after the retraction began. On the lateral cephalogram, several parameters were compared, including U6 to Ptm, upper lip to E - line, lip strain, L1 - Apog, L1 - NB (angular), L1 - NB (linear), U1 - SN, U1 - NA (linear), and L1 - NA (angular). To measure the length of the arch, a horizontal line was drawn connecting the mesial fossa of the first molars in the same arch. Additionally, a perpendicular line was drawn from the center of the two central incisors. Results: There was a significant difference in the measurements of U1 - SN (degree), U1 - NA, L1 - Apog (in mm), and L1 - NB (in mm) before and after treatment in the IZC group. There was a significant difference in the measurements of U1 - SN, U1 - NA (mm), L1 - Apog (in mm), and L1 - NB (in mm) before and after treatment in the IZC group. Conclusion: The effectiveness of IZC screws in en masse distalization and tooth retraction while maintaining arch length was found to be statistically significant, as shown by radiographic measures and cast measurements in the maxilla and mandible, when compared to conventional procedures.
