Facilitating Direct Bonding for Lingual Retainers.

Directly bonded lingual retainers are not always easy because the available techniques do not keep the wire totally stable in position and there is risk of moist contamination. Indirect methods help to keep a moist-free environment and reduce chair time but have other drawbacks, such as lack of control over the composite placement leading to adhesive-tooth failure or undesirable flow of adhesive to gingival embrasures. The purpose of this report is to show a direct bonding method, helped by a laboratory made acrylic guide, which has benefits of direct and indirect techniques.
