Objective probe into method and clinical significance of casting cavity - retention form post - core crown in restoring residual crown and root of the short molar
摘要目的：探討短磨牙殘根殘冠洞固位形鑄樁核冠修復的方法和臨床意義。 -
Methods one hundred and twenty residual crowns and roots of short molars were restored with casting cavity - retention form post - core crown and followed up for 2 ~ 5 years to observe the clinical effect
方法：對120顆短磨牙殘根殘冠應用洞固位形鑄造樁核冠修復，對其臨床效果隨訪2 ~ 5年。 -
Conclusion casting post - core crown with cavity retention form is a convenient technique which can restore the residual crown and root of the short molars effectively and optimize the retention form as well
結論：洞固位形鑄造樁核冠修復短磨牙殘根殘冠既方便，簡潔，又解決修復體固位困難問題。 -
The main works and results we have accomplished are as follows : 1 ) red - detuned locking of cooling / trapping laser to the cycling transition of cesium cooling has been accomplished by means of a double - passed acoustic - optical frequency shifting system and the technique of saturated absorption spectroscopy. the short - term residual frequency jitter is less than 350khz ; 2 ) automatic controlling system by computer programs has been established for laser cooling and trapping and cavity qed experiment. the laser and magnetic fields can be controlled by the acoustic - optical modulator and the electronic - controlled logic gate respectively
具體如下： 1 ）採用了往返兩次通過的聲光頻移系統結合飽和吸收光譜技術的實驗方案，實現了冷卻俘獲激光頻率相對于銫原子冷卻循環躍遷的負失諧鎖定，短期頻率穩定度約在350khz以內，並可方便地調節其負失諧量而無須對后續光路再作調整； 2 ）建立了一套基於計算機程序控制的、銫原子激光冷卻與俘獲實驗所需的時序控制系統。
