Abstract
To date, treating vertical food impaction with open contact effectively, especially with an atraumatic therapy, remains a challenge. In this study, we developed a simple, atraumatic, and economic therapeutic measure to treat vertical food impaction. The scientific rationale of our therapeutic technique is to restore an intact and firm proximal contact with proper location and form relationships to prevent forceful interproximal wedging of food, which in turn protects interdental papilla. We performed the procedure using flowable composite resin or composite resin cement with the aid of a cerclage wire under tension to rebuild the contact area. The reported method is especially useful for some challenging clinical cases, such as food impaction after crown and inlay on onlay restoration, and some conventional treatment methods, such as contouring the marginal ridge and developmental grooves, are ineffective.
Highlights
Food impaction is the occlusal force wedging of food into interproximal periodontal tissue and is classified into vertical and horizontal [1]
Horizontal food impaction is characterized by lateral pressure from lips, cheeks, and tongue, forcing food dregs and fibers into the enlarged interproximal gingival embrasure for gingival recession caused by all kinds of periodontal disease
Food impaction associated with open contact causes more probing depth and clinical attachment loss interproximally than that associated with uneven marginal ridge
Summary
Food impaction is the occlusal force wedging of food into interproximal periodontal tissue and is classified into vertical and horizontal [1]. Horizontal food impaction is characterized by lateral pressure from lips, cheeks, and tongue, forcing food dregs and fibers into the enlarged interproximal gingival embrasure for gingival recession caused by all kinds of periodontal disease. This situation is relatively more tolerable compared with vertical food impaction because the food dregs can be removed using a dental floss or a tooth pick in gingivoocclusal direction, giving a momentary relief.
