During orthodontic treatment with miniscrews, complications such as aphthous ulceration, soft-tissue coverage of the miniscrew head, soft-tissue inflammation, infection, and peri-implantitis can occur. Good hygiene can prevent inflammation by infection but does not prevent traumatic oral mucosal lesions at the buccal mucosa. The authors review and describe the use of a physical barrier to cover the miniscrew head and prevent soft-tissue trauma.
