口内数字印模用于全瓷冠修复的优势

The Advantage of Intraoral Digital Impressions on All- ceramic Crowns

为研究口内数字印模在全瓷冠修复方面的应用优势,选取2014年1月——2015年5月,在本院口腔科就诊要求全瓷单冠修复的患者40人、共40颗牙齿,随机分为a、b两组,每组20人、20颗牙齿,a组采取传统印模方式制取石膏模型,b组采用口内数字印模方式取得数字化印模,分别制作全瓷冠修复牙齿,观察记录两组全瓷冠边缘的密合程度及制取模型所用的操作时间,两组比较,以判断数字印模的优势。发现两组全瓷冠边缘的密合程度均可,数字印模组成功率优于传统印模组。数字印模组操作时间大大短于传统印模组,明显优于传统印模组。说明口内数字印模在全瓷冠制取方面有明显优势,精准度高且节约时间、材料,可提高患者舒适度、满意度。

To study the advantages of intraoral digital impression in the preparation of all ceramic crowns. 2014 and 2015 in the hospital, Department of Stomatology, the requirements of all ceramic single crown repair of 40 patients with, a total of 40 teeth teeth, were divided to two groups, with 20 cases in each group, 20 teeth, respectively, to take the traditional impression way for preparing gypsum model and intraoral digital impression made digital impression, make all ceramic crown in the restoration of teeth respectively, to observe and record operating time of the two groups all ceramic crown on the edge of the dense degree and production model, two groups compared to determine the advantages of digital impression. The two groups all ceramic crown edge sealing degree can group the success rate is better than the traditional digital impression impression group. The digital impression group operation time is much shorter than the traditional impression group is obviously superior to the traditional model. Intraoral digital impression in all ceramic crown preparation has obvious advantages, high precision, and to save time, materials, and improve the comfort degree of patients satisfaction.
