1.3治療結(jié)果
病人戴用改良固位型活動矯治器后,矯治器在口內(nèi)固位良好,無明顯不適感,部分全天戴用的病人在進(jìn)食時亦無松動脫落而影響矯治器佩戴的情況。每次復(fù)診時檢查固位、加力裝置及病人的口腔衛(wèi)生情況,觀察粘接劑的磨損情況。病人全部完成矯治,時間2~8個月,平均矯治時間4.5個月。
固位是加力型活動矯治器矯治成功的關(guān)鍵。評價一個活動矯治器的臨床表現(xiàn)如何,固位甚至比矯治彈簧更重要,如果矯治器經(jīng)常脫位,矯治就起不到應(yīng)有的作用。為了獲得更好的固位,卡環(huán)的固位點(diǎn)必須與倒凹區(qū)吻合,對于替牙期病人,該點(diǎn)可能必須稍微進(jìn)入部分牙齦溝。如果加力頻繁或者加載的力值大,就需要更多的卡環(huán)來幫助增強(qiáng)固位?;顒映C治器的固位裝置主要包括單臂卡、鄰間鉤和箭頭卡等卡環(huán),對于活動矯治器佩戴的固位效果來說,固位牙條件差的病人,都沒有合適的倒凹區(qū)讓卡環(huán)卡入,無論是箭頭卡、單臂卡或者鄰間鉤,都難以形成良好的固位,一旦加力,矯治器就會明顯松動、出現(xiàn)間隙甚至脫落。
