Abstrakt:	Class I bimaxillary protrusion is characterized by proclined incisors, a convex facial profile, procumbent lips, and increased lip strain. Treatment includes the extraction of premolars and the mesial movement of the proclined anterior teeth in the extraction spaces to correct the inclination. This case report describes the treatment of an 18-year-old male patient who presented with class I bimaxillary protrusion and procumbent lips. Clinical examination revealed a convex profile, potentially competent lips, and increased lip strain. The treatment plan included therapeutic extraction of all first premolars and complete retraction of the anterior teeth in the extraction spaces. Absolute anchorage was required, and therefore, mini-implants were placed in both the upper and lower arches. Sliding mechanics were used to retract the anterior teeth in the extraction spaces. The use of mini-implants for absolute anchorage allowed for complete retraction of the anterior teeth without the inadvertent mesial movement of the posterior teeth. Posttreatment, the inclination of the anterior teeth was corrected, achieving normal overjet and overbite. Lip procumbancy was reduced, resulting in a more harmonious facial profile.
