        【摘要】目的比較玻璃離子或樹脂?墊與傳統(tǒng)?墊舌簧矯治器在治療乳牙期和混合牙列早期前牙反?時的效果。方法選取10位能熟練運用這兩種方法治療前牙反?的醫(yī)師,設(shè)計21個調(diào)查項目進行問卷調(diào)查,對調(diào)查結(jié)果進行問卷打分,以評價這兩種方法的效果。結(jié)果玻璃離子或樹脂?墊與傳統(tǒng)?墊舌簧矯治器在21項比較內(nèi)容中,在矯治療程問卷評分分別為3.90±1.88和3.80±2.10,兩者比較無統(tǒng)計學(xué)意義;在口腔印模制取、矯治器制作簡單性、綜合評價等其余20項評價指標,兩種治療方法的評分比較均有統(tǒng)計學(xué)差異(P<0.05)。結(jié)論在治療乳牙期及混合牙列早期的前牙反?時,玻璃離子或樹脂?墊的療效優(yōu)于傳統(tǒng)的?墊舌簧矯治器,值得臨床推廣。

        【關(guān)鍵詞】玻璃離子或樹脂墊;墊舌簧矯治器;乳牙期;混合牙列前期;前牙反

        1對象與方法

        1.1對象選取武警總醫(yī)院和北京市平谷區(qū)婦幼保健院口腔科共10位醫(yī)師,他們能熟練采用玻璃離子或樹脂墊矯治乳牙期和混合牙列早期前牙反,同時也能熟練應(yīng)用墊舌簧矯治器治療前牙反。

        1.2調(diào)查方法調(diào)查項目共計21項,即口內(nèi)取印模、矯治器制作簡單性、佩戴初期舒適度、矯治器適應(yīng)期長短、矯治器佩戴時間、矯治器鋼絲折斷、矯治器鋼絲劃傷牙齦或黏膜、治療中前牙松動、治療中牙齒疼痛、復(fù)診間隔時間、口腔衛(wèi)生情況、矯治療程長短、醫(yī)療成本、對下前牙矯治作用、尖窩關(guān)系密合程度、咀嚼效率、發(fā)音、美觀、患兒配合程度、監(jiān)護人接受程度、綜合評價。

        1.3評定標準在評定前,對醫(yī)師評定標準進行校準,然后對這21個調(diào)查項目進行問卷打分。每個調(diào)查項目設(shè)6個等級的感受,采用5分制:不能接受(0分),一般(1分,2分),良好(3分,4分),滿意(5分)。

        1.4統(tǒng)計學(xué)處理使用SPSS17.0,將10位醫(yī)師對這兩種方法評價的21個指標的感受分數(shù)使用成組t檢驗進行統(tǒng)計學(xué)比較,P<0.05為差異有統(tǒng)計學(xué)意義。

        2結(jié)果

        兩種矯治方法在矯治療程長短上無統(tǒng)計學(xué)差異,其余項目評分兩種方法比較均有統(tǒng)計學(xué)差異,玻璃或樹脂墊的療效優(yōu)于傳統(tǒng)的墊舌簧矯治器(P<0.05,表1)。

        表1 醫(yī)師對兩種矯治方法項目調(diào)查分值比較 (n=10;±s)

        3討論

        6~12歲孿生子遺傳與環(huán)境作用的研究發(fā)現(xiàn),下頜前后位置關(guān)系最容易受環(huán)境因素的影響,而面部高度受強遺傳因素的控制,特別是面前部的高度[7,8]。這增加了本研究利用玻璃離子墊矯治混合牙列早期及乳牙期前牙反的信心。

        【Abstract】ObjectiveTo compare the advantage and disadvantage of occlusal guidance of glass ionomer cement or resin with traditional splint and lingual spring in clinical through the questionair for doctor.Methods21 research items were investigated by 10 clinical doctors who can accomplish the therapy with those two methods to correct anterior crossbite skillfully. And the research items were: whether the oral impression, making appliance simplicity, early period comfort when wearing appliance, the length of appliance adaptation, appliance wearing time, wire broken of appliance, appliance wire scratching gingival mucosa, anterior tooth loose in the treatment, dental pain in the treatment, follow-up interval, oral hygiene, treatment duration, medical cost, the lower anterior teeth correction, cusp and fossa relationship close together, masticatory efficiency, pronunciation, appearance, children with the degree, the acceptance of guardian, comprehensive evaluation.ResultsComparing the two treatment methods of 21 research items,the occlusal guidance of glass ionomer cement or resin and the traditional splint lingual spring in the course of orthodontic treatment, the questionnaire scores were 3.90±1.88 and 3.80±2.10, there was no statistically significant difference (P>0.05). However, for the oral impression, making appliance simplicity, comprehensive evaluation and other 20 evaluation items: the scores of the two treatment methods had highly significant difference (P<0.05).ConclusionCompared with the traditional splint and lingual spring to correct anterior crossbite, the occlusal guidance of glass ionomer cement or resin is a fixed functional appliance, which can be easily operated in clinic and has many advantages. This technology is worthy of extensive promotion.
