Distalization using retro-tuberosity screws: Presentation of four clinical cases

Area of Science:

• Orthodontics
• Dental Implantology

Background:

• Class II malocclusions require effective treatment options.
• Retro-tuberosity screws (RTSs) are an under-documented therapeutic alternative.

Purpose of the Study:

• To present a case series managed using RTSs for Class II malocclusion correction.
• To evaluate the efficacy and limitations of RTSs in orthodontic treatment.

Main Methods:

• Presentation of four clinical cases treated with RTSs.
• Focus on sequential distalization for malocclusion correction.

Main Results:

• RTSs facilitated effective sequential distalization.
• Adverse effects were minimal, with a noted risk of vestibular-palatal angulation.
• Screw placement challenges and the need for third molar absence were observed.
• Failure rates were comparable to other intraoral screw placements when using 2 mm diameter screws.

Conclusions:

• RTSs are a viable option for distalizing teeth in adults with Class II malocclusions or asymmetries, particularly when third molars are absent.
• Further randomized controlled trials are necessary to establish definitive indications and limitations.
