Abstract

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.

摘要：

目的探究引导树脂粘接技术对垂直型食物嵌塞的治疗效果,为垂直型食物嵌塞的治疗提供新的方法。方法对76例垂直型食物嵌塞患者用流体树脂进行引导树脂粘接治疗,使用特殊的触点成型线辅助触点成型,粘接在橡皮障环境下使用流动树脂用全酸蚀技术进行;治疗后按“完全不塞”=3、“改善明显”=2、“轻微改善”=1、“完全没变化”=0的评分标准对患者主观感受进行评分,并在12个月内对患者感受进行随访。记录1~3分为有效,统计不同时间点有效率。结果在治疗当天、治疗后1、3、6、12个月患者主观感受评分分别为2.47、2.21、1.79、1.30、0.97。各时间点的评分差异存在统计学意义(P<0.01)。治疗当天有效率达到91.78%,在半年内维持50%以上。树脂脱落或断裂的患者经过处理后症状均得到重新改善。结论引导树脂粘接技术可即刻缓解垂直型食物嵌塞症状,在短期内持续有效。对树脂脱落或断裂的进一步处理有助于巩固其疗效。

Figure 1 Interproximal contact shaping wire for teeth Contact shaping wire includes a guiding segment and a shaping segment. The guiding segment is thinner, similar to dental floss, and continues with the thicker shaping segment. The diameter of the shaping segment is constant

Figure 2 Operation process of composite resin cementation guided by contact shaping wire for the treatment of vertical food impaction a: application of resin adhesive with air blowing and light curing; b: engagement of the contact shaping wire into the interdental space, the guiding segment of the wire was oriented to enter the interdental space from the occlusal direction, and was then pulled until the shaping segment enters the interdental space; c: the wire was then clamped tightly with a vessel clamp; d: flowable resin was injected into the area delimited by the contact shaping wire. Excessive resin was removed with a probe; e: final outcome of guided resin cementation, teeth 35 and 36 were cemented with composite resin. The surface of the resin was smooth, continuous with the tooth configuration. No overhang was formed in the process
