The treatment of Angle Class I malocclusion by atypical extraction is rather challenging. The extraction of four first premolars often manages it. However, in cases of compromised and non-restorable teeth, the extraction decision may be altered, making the anchorage and the treatment mechanics more challenging. This article reports the clinical case of a 16-year-old patient from Sudan who presented with a chief complaint “My teeth are crooked and sticking out.” He had Angle Class I malocclusion with a bimaxillary dentoalveolar protrusion. He had severe crowding in both arches and localized marginal gingivitis related to an ectopically erupted upper right canine (UR3) and lower right first premolar (LR4). The patient had a provisional restoration in the lower right first molar (LR6). Extraction of three first premolars and one first molar was the alternative of choice for this treatment, which restored function, providing improved periodontal health, achieved the desired facial esthetics, and allowed finishing with a stable and balanced occlusion. Management of angle class I malocclusion with atypical extraction patterns should be performed with careful mechanics and anchorage planning to obtain good results.
