The lower incisor to APo decreased from +4 to +2.5, which is slightly closer to norm. The E-plane was increased approximately 2 mm upper and lower, which is common in extraction cases. In his case, this did not significantly effect his profile aesthetically. 127º 87º 99º +4 mm -4.4 76º 74º 76º 44º -8/-5 mm SUMMARY Case selection and diagnosis with a clear expectation of treatment goals and results are paramount to any orthodontic case. Adult cases with skeletal discrepancies can many times only be adequately treated with surgical intervention. In some cases with mild to moderate skeletal discrepancies with significant crowd-ing, extraction of bicuspid teeth can offer a reasonable alternative to surgery and provide an acceptable result for your patient. This case shows a good and improved result, but with the expected compromise that not all teeth inclinations will be ideal. Understanding the mechanics of your bracket system and applying your treatment technique to maxi-mize benefits can greatly improve your results. www.orthodontics.com Fall 2020 13
