醫(yī)源性因素對(duì)光固化復(fù)合樹(shù)脂邊緣微滲漏的影響

[摘要]光固化復(fù)合樹(shù)脂是臨床上常用的充填修復(fù)材料，但可因邊緣微滲漏導(dǎo)致修復(fù)失敗。邊緣微滲漏是多種因素作用的結(jié)果，本文就窩洞制備、粘接、充填、光固化、拋光等臨床醫(yī)源性因素對(duì)光固化復(fù)合樹(shù)脂邊緣微滲漏的影響作一綜述，以期為臨床實(shí)踐提供參考。

[關(guān)鍵詞]光固化復(fù)合樹(shù)脂;聚合收縮應(yīng)力;邊緣微滲漏;窩洞制備;粘接系統(tǒng);分層充填;光固化;拋光

Abstract： Light-cured composite resin is a filling and restorative material in Clinic， but it can fail due to microleakage. Microleakage is the result of multiple factors. This article reviews the influence of iatrogenic factors such as cavity preparation， bonding， filling， light curing， and polishing on the microleakage of light-cured composite resin， in order to provide references for clinical practice.

Key words： light-cured composite resin; polymerization shrinkage stress; microleakage; cavity preparation; adhesive system; incremental technique; light curing; polishing

光固化復(fù)合樹(shù)脂具有良好的機(jī)械性能、美觀及操作簡(jiǎn)便等優(yōu)點(diǎn)，在臨床上被廣泛應(yīng)用于充填修復(fù)治療[1]，但充填后邊緣微滲漏的問(wèn)題一直是眾多學(xué)者關(guān)注的焦點(diǎn)。（剩余14106字）
