Aim: The aim of this retrospective study was to evaluate the maxillary transverse dimensions in individuals with palatal impacted maxillary canines relative to the control group without dental impactions using cone-beam computed tomography(CBCT). Methods: Sixty CBCT images of the individuals were classified into two groups: 29 in the palatal impacted canine group and 31 in the control group. To determine the maxillary width at four levels, CBCT DICOM files were processed using the software OnDemand 3D to analyze maxillary transverse parameters. Basal width at molar (BWM), alveolar width at first molar (AWM), basal width at premolar (BWPM), and alveolar width at premolar (AWPM) were the four levels at which the maxillary transverse dimensions were measured. The independent T- test was utilized when comparing the impacted canine group and the control group. The level of statistical significance was set at a P-value less than 0.05 for all tests.Results: Regarding the transverse maxillary measurement, there was no significant difference between the impacted canine group and the control group for the BWM, BWPM, and AWPM (P≥0.05). For the AWM, statistically significant differences were not found between the maxillary palatal impacted canine group and the control group (P=0.05).Conclusion: No significant differences were observed between the impacted canine group and the control group in terms of maxillary transverse dimensions. Further research is needed to explore the relationship between maxillary canine impaction and maxillary transverse dimensions.

Aim: Maxillary transverse deficiencies pose significant challenges in orthodontics, necessitating effective treatment methods. Traditional approaches like rapid maxillary expansion (RME) have demonstrated limitations, especially in skeletally mature patients. Skeletal anchorage-based expansion methods, such as miniscrew-assisted rapid maxillary expansion (MARME), have emerged as viable alternatives, offering advantages in terms of reduced dental side effects and improved stability.Report of a Case: A 14-year-old female presented with a severely constricted maxillary arch and intricate occlusal issues. This case report details the utilization of MARME as a treatment modality. Miniscrews were strategically placed by an orthodontist specialist, and the expansion process was carefully monitored. Post-treatment outcomes revealed a significant increase in midpalatal suture opening width, showcasing the effectiveness of MARME. Cone beam computed tomography images demonstrated a notable expansion of the transverse dimension, leading to improved occlusal relationships.Conclusion: Skeletal anchorage-based expansion, particularly MARME, stands out as a preferred method for addressing maxillary constriction in adolescents. This case serves as an illustration of the feasibility and distinctive advantages of Temporary Anchorage Devices (TADs) in the context of maxillary expansion for skeletally mature patients.
