Introduction and Objectives: The extraction versus nonextraction controversy is the oldest as well as the most enduring controversy and still remains a topic of debate in the field of orthodontics. The “American Board of Orthodontics” (ABO-1998) introduced an index called the objective grading system (OGS) which evaluates posttreatment dental casts and panoramic radiographs. It assesses the final occlusion in first, second, and third orders according to eight different occlusal components. The aim of the present study was to evaluate the treatment outcome of extraction and nonextraction cases in borderline cases by ABO-OGS system. Materials and Methods: Forty borderline orthodontic patients with Angle's Class I malocclusion with an age group of 13–20 years were selected and equally divided into two groups: twenty patients were treated by extraction of all first premolars and twenty patients with a nonextraction treatment protocol. MBT 0.022” slot prescription was used for all forty patients. With the aid of an ABO measuring gauge and panoramic radiographs, the total OGS scores between the two groups were calculated and compared using Student's t-test. Results: The mean OGS scores were significantly less negative in the extraction group (−22.0 ± 2.29) as compared to the nonextraction group (−26.80 ± 5.18, P < 0.005). Conclusion: According to this study, in the borderline cases, the final occlusion and radiographical characteristics were more acceptable in the patients treated with extraction than the nonextraction patients.
