Orthodontics OSCE Practice Exam

Creating additional space in the dental arch can be achieved through a variety of orthodontic techniques, each serving a unique purpose and benefiting the overall treatment plan.

Stripping, also known as interproximal reduction, involves the removal of a small amount of enamel from the sides of teeth. This method helps in creating space by reducing the mesiodistal width of certain teeth without significantly affecting their overall size and aesthetics. Clinically, it is often used when teeth are slightly over-crowded and minimal space is required.

Proclination focuses on tilting the teeth in a facial direction. By angling the incisors forward, slight spacing can be gained in the arch, particularly in cases where the incisors are initially positioned more upright. This technique is often incorporated into treatment strategies when improving the arch form or alignment is needed.

Distalisation, on the other hand, refers to moving the posterior teeth back in the arch. This approach helps in creating space by shifting the molars distally, thus increasing the overall arch length and relieving crowding, particularly in the anterior region. Distalisation is commonly employed in cases where extraction is avoided, or when expanding the dental arch is necessary for aesthetic or functional improvements.

Recognizing that all three methods—
