乳牙滯留的寶寶最常見于混合牙列早期下頜中切牙,恒牙在舌側萌出,乳牙滯留在唇側,表現為雙排牙現象。其次是第一乳磨牙的殘根或殘冠滯留于第一前磨牙頰舌側或近遠中。第二乳磨牙滯留,多是恒牙胚先天缺失或埋伏阻生。上頜牙齒在滯留乳牙腭側萌出,可能會造成反合,也就是俗話說的“地包天”。

繼承恒牙已經萌出,滯留的乳牙應該拔除。上頜滯留的乳牙一定要盡早拔除,以免造成恒牙反合。如果已經出現反合現象,一定要密切監測,在前牙萌出后盡早進行矯正森林舞会APP。下頜滯留乳牙拔除后,長在后面的恒牙會自行調整到正常位置,如果因為擁擠牙齒排列不齊,應該觀察,牙齒替換后根據牙列情況擇期矯正。下頜滯留乳牙由于牙根吸收不足,在拔除的過程中可能會出現牙根斷裂現象,由于殘留牙根距離繼承恒牙牙根較近,因此可以不做處理,殘留牙根會自行吸收或隨恒牙萌出排出體外。

因先天缺失繼承恒牙導致的滯留乳牙可不予處理。但是要密切觀察滯留乳牙,積極預防齲齒森林舞会APP的發生,盡量延后牙齒脫落時間。如果寶寶牙齒脫落,要根據牙齒排列情況進行間隙管理。

如何預防乳牙滯留

 

森林舞会APP YUFANGRUYAZHILIU,YIDINGYAOCONGXIAOJIAQIANGDUIRUYADEBAOHU,XIAMIANSHIERTONGHUANYAQIJIANDEHULICHANGSHI——

乳牙保護從孕期開始

在乳牙釉質的鈣化期,即懷孕4個月到嬰兒出生后第一年,孕媽咪要注意補鈣,并拒絕吸煙或遠離二手煙。醫學研究表明,孕媽咪經常吸煙或被動吸煙,會導致胎寶寶頜面部或口腔發育畸形,引發出很多牙齒問題和牙周疾病。此外,孕期一定要慎用藥物。很多藥物對胎寶寶的口腔和牙齒發育有害。

盡量采取母乳喂養

寶寶有力吸吮母乳的動作,有利于頜面正常發育。人工喂養如果人造奶嘴使用不當,極易造成面部和牙頜異常,必須人工喂養時,應選擇模仿乳頭仿真設計的奶嘴。盡早訓練寶寶使用杯子和碗筷進食,避免形成對奶瓶的依賴性。此外,母乳還可抑制細菌在牙齒上繁殖,防止牙齒腐爛。

媽咪應積極治療齲齒

避免不正確的哺乳姿勢

控制寶寶吃糖

斷奶后,每天飲食中要有五谷雜糧、牛奶森林舞会APP及奶制品及蔬菜和水果,牛奶中盡量不加糖;多喝白開水,少喝糖分高的飲料。為寶寶提供有一定硬度的食物練習咀嚼,如蘋果、小紅蘿卜、黃瓜、玉米等。尤其是新鮮水果,咀嚼時間越長,唾液分泌越多,增多的唾液會把牙齒清洗干凈,同時增強咀嚼功能。

定期檢查

避免寶寶經常做吮指、吮唇、吐舌等動作。尤其是4歲以后,一定要徹底糾正吸吮安撫奶嘴的習慣。寶寶出現小乳牙早失時,趕快帶到牙科做牙齒間隙保持,不然會影響恒牙的發育和萌出,出現反頜、牙列擁擠、牙齒錯位等情況,也應及早去口腔科,積極配合醫生治療,盡快矯正過來。總之,要經常檢查寶寶的牙齒,一旦發現問題,就應該盡早上醫院治療。
