Objective: This study aimed to determine the orbit vector relationships between different types of malocclusion supported by cephalometric analysis. Materials and Methods: This retrospective study was conducted on 69 patients who were diagnosed with orthodontic malocclusion. Demographic information, such as age and gender, were provided from the medical records of the patients. Cephalometric analysis was performed by an expert orthodontist to determine the anteroposterior skeletal relationship. The orbit vector relationship was evaluated by digital patient photographs taken by the Frankfort horizontal plane by two different ophthalmologists. Results: The mean age of the patients was 14.58±3.95 (range, 8-28) years. Forty-five (65.2%) of the patients were female and 24 (34.8%) were male. Positive orbit vector patients had significantly higher SNA measures and ANB readings than negative orbit vector patients (pSNA=0.014, pANB=0.001). There was no difference in orbit vector status between Class I and II malocclusion groups (p=0.580). Negative vectors were more common in the Class III group than in the Class I (p=0.039) and Class II (p=0.004) groups. Conclusion: The majority of patients in the Class I and II groups had a positive orbit vector, whereas patients in the Class III group had a negative orbit vector relationship.
