ABSTRACT
Objective@# To explore the clinical effect of a guided resin cementation technique on vertical food impaction symptoms and to provide a new method for the treatment of vertical food impaction. @* Methods @#Treatment of 76 patients with vertical food impaction with guided resin cementation was performed. A specially fabricated contact shaping wire was used to aid the shaping of the contact. Cementation was applied under a rubber dam with the total-etch technique with flowable composite resin. Patient subjective perception was recorded after treatment (i.e., “totally relieved”=3, “significantly improved”=2, “slightly improved”=1 and “no change”=0). Follow-up visits lasted for one year. Scores of 1 to 3 were recorded as effective. The efficiency rates at different times were calculated. @*Results@#Patient subjective perceptions scored 2.47, 2.21, 1.79, 1.30 and 0.97 on the day immediately after and 1, 3, 6, and 12 months after treatment, respectively. There were significant differences among scores at each time point (P<0.01). The Efficacy rate reached 91.78% immediately after treatment and was sustained above 50% within half a year. Management of resin debonding or fracture successfully relieved the symptoms again.@*Conclusion@#The guided resin cementation technique relieves vertical food impaction symptoms immediately, and the effect of the guided resin cementation technique is maintained for a short period of time. Management of resin debonding or fracture helps consolidate treatment outcomes.
