Class I malocclusion with severe double protrusion treated with first premolars extraction

Area of Science:

• Orthodontics
• Dental Malocclusion
• Facial Orthopedics

Background:

• Angle Class I malocclusion with bimaxillary protrusion presents with significant buccal incisor tipping, leading to protruded lips.
• This condition necessitates orthodontic intervention to improve facial convexity and dental alignment.

Observation:

• The case study focuses on a patient with Angle Class I malocclusion and bimaxillary protrusion.
• Severe buccal tipping of incisors was a key characteristic, contributing to the protrusion of both upper and lower lips.

Findings:

• First premolar extraction is a recommended strategy for reducing facial convexity through anterior teeth retraction.
• Controlled space closure, focusing on overbite and incisor torque, is crucial for achieving ideal esthetic and cephalometric results.
• Maximum posterior anchorage is often required for successful treatment outcomes.

Implications:

• Effective management of bimaxillary protrusion can significantly enhance facial esthetics and patient satisfaction.
• The findings contribute to the understanding of orthodontic treatment strategies for complex malocclusions.
• Successful case presentation to the Brazilian Board of Orthodontics and Facial Orthopedics (BBO) validates the treatment approach.
