背景：光固化树脂是一种新型材料，具有色泽美观、强度高、应用广泛、操作简便且价廉等特点。修复时不磨牙或少磨牙，患者乐于接受。<br> 目的：观察光固化树脂充填上颌前牙过大间隙的效果。<br> 方法：共收治32例患者，75个上颌大间隙，107颗牙齿；其中男15例，女17例；年龄21-52岁；牙位分别为双侧中切牙1个间隙，14例；双侧中切牙、左侧侧切牙、左尖牙3个间隙，3例；双侧中切牙、右侧侧切牙、右侧尖牙3个间隙，2例；左侧中切牙、侧切牙、尖牙和右侧中切牙、侧切牙4个间隙，3例；双侧中切牙和侧切牙3个间隙，6例；左侧中切牙、侧切牙和右侧中切牙、侧切牙、尖牙4个间隙，4例。均采用光固化树脂充填过大上颌前牙间隙。随访观察牙冠形态，密合度、颜色、磨损程度及松动度情况。<br> 结果与结论：随访3年，32例患者中修复成功17例，树脂修得的牙冠形态及密合度良好，修复体不松动脱落，无任何变色；修复基本成功9例，修复的牙冠形态及密合度欠佳，修复体不松动脱落，但在龈缘处和牙体接触处修复体有缺陷，有轻度变色；修复失败6例，牙冠形态及密合度较差，修复体松动或脱落，修复体严重变色，需要重新修复。
揹景：光固化樹脂是一種新型材料，具有色澤美觀、彊度高、應用廣汎、操作簡便且價廉等特點。脩複時不磨牙或少磨牙，患者樂于接受。<br> 目的：觀察光固化樹脂充填上頜前牙過大間隙的效果。<br> 方法：共收治32例患者，75箇上頜大間隙，107顆牙齒；其中男15例，女17例；年齡21-52歲；牙位分彆為雙側中切牙1箇間隙，14例；雙側中切牙、左側側切牙、左尖牙3箇間隙，3例；雙側中切牙、右側側切牙、右側尖牙3箇間隙，2例；左側中切牙、側切牙、尖牙和右側中切牙、側切牙4箇間隙，3例；雙側中切牙和側切牙3箇間隙，6例；左側中切牙、側切牙和右側中切牙、側切牙、尖牙4箇間隙，4例。均採用光固化樹脂充填過大上頜前牙間隙。隨訪觀察牙冠形態，密閤度、顏色、磨損程度及鬆動度情況。<br> 結果與結論：隨訪3年，32例患者中脩複成功17例，樹脂脩得的牙冠形態及密閤度良好，脩複體不鬆動脫落，無任何變色；脩複基本成功9例，脩複的牙冠形態及密閤度欠佳，脩複體不鬆動脫落，但在齦緣處和牙體接觸處脩複體有缺陷，有輕度變色；脩複失敗6例，牙冠形態及密閤度較差，脩複體鬆動或脫落，脩複體嚴重變色，需要重新脩複。

BACKGROUND:Light-cured resin is a new kind of material with beautiful color, high strength, wide range of applications, easy-to-use and inexpensive features. Patients are wil ing to accept it because of less or no grinding of the teeth. <br> OBJECTIVE:To observe the effect of light-cured resin to fil the interdental space between maxil ary anterior teeth. <br> METHODS:A total of 32 patients aged 21-52 years were enrol ed, 107 teeth with 75 oversized maxil ary spaces, including 15 males and 17 females. One space between bilateral central incisors was found in 14 cases;three spaces between bilateral central incisors, left lateral incisor, and left canine were found in three cases;three spaces between bilateral central incisors, right lateral incisor, and right canine were found in two cases;four spaces between left central incisor, left lateral incisor, left canine, right central incisor, and right lateral incisor were found in three cases;three spaces between bilateral central incisors and lateral incisors were found in six cases;four spaces between left central incisor, left lateral incisor, right central incisor, right lateral incisor, and right canine were found in four cases. Al the oversized maxil ary spaces were fil ed with light-cured resin. Then, crown morphology, adaptation, color, degree of wear and loosening were observed during fol ow-up. <br> RESULTS AND CONCLUSION:After 3-year fol ow-up, 17 of 32 cases were successful in tooth repair:the crown morphology and tooth adaptation were good, and there was no prosthesis loosening or detachment and discoloration. The tooth space was repaired basical y in another nine cases:the crown morphology and tooth adaptation were not good enough, no prosthesis loosening or detachment was found, but there were some defects at the gingival margin and contact surface of teeth as wel as mild discoloration. Tooth repair failed in the other six cases with worse crown morphology and adaptation, prosthesis loosening or detachment, and severe discoloration, which need to be repaired again.
