[摘要] 目的 對比鈷鉻合金烤瓷牙和二氧化鋯烤瓷牙修復效果。 方法 回顧性分析2010年1月—2013年12月在該科進行烤瓷牙修復術的96例(172顆牙)的臨床資料,采取二氧化鋯烤瓷牙的患者有38例(70顆牙),作為二氧化鋯組;采取鈷鉻合金烤瓷牙的患者有58例(102顆牙),作為鈷鉻合金組,對比兩組患者的臨床效果。 結果 二氧化鋯的有效率34例(94.73%)與鈷鉻合金組的有效率53(91.37%)相比,差異無統計學意義(χ2=0.87,P>0.05)。但是兩組患者治療后,鈷鉻合金組并發癥發生率高于二氧化鋯組,差異有統計學意義(χ2=3.95,P<0.05)。 結論 二氧化鋯烤瓷牙的療效優于鈷鉻合金烤瓷牙,若患者經濟條件允許,應該優先考慮二氧化鋯烤瓷牙。

[Abstract] Objective To compare repairing effect of cobalt chromium alloy porcelain teeth and zirconium dioxide porcelain teeth. Methods To retrospective analyze 96 cases(172 tooth)clinical data of porcelain teeth prosthesis in our department from January 2010 to December 2013, the patients of zirconium dioxide porcelain teeth were 38 cases(70 tooth),which was zirconium dioxide porcelain teeth group,the patients of cobalt chromium alloy porcelain teeth were 58 cases(102 tooth), which was cobalt chromium alloy porcelain teeth group,the clinical result of two groups were compared. Results The effective rate 34 cases(94.73%)of zirconium dioxide porcelain teeth and effective rate 53 cases(91.37%)of cobalt chromium alloy porcelain teeth were compared, which was no difference(χ2=0.87,P>0.05). But after treatment of two groups,incidence of complications of cobalt chromium alloy porcelain teeth group were higher than those of zirconium dioxide porcelain teeth group(χ2=3.95,P<0.05), the difference were statistical significance. Conclusion The effective result of zirconium dioxide porcelain teeth are better than that of zirconium dioxide porcelain teeth. Zirconium dioxide porcelain teeth is the first choice for patients with good economic conditions.

烤瓷牙是目前臨床牙體現代美容與修復的重要之一,其指的是用鑄造貴金屬作為支撐的內核,而后通過高溫條件將專用的瓷性材料繞結在貴金屬表面,并模仿正常牙體的一種牙齒修復方式[1-2]。由于烤瓷牙具有與牙體相近的外形、色澤,臨床運用中獲得了較滿意的修復效果[3-4]。該課題研究中主要分析了鈷鉻合金烤瓷牙與二氧化鋯烤瓷牙在臨床應用中的分析效果,現報道如下。
1 資料與方法
1.1 一般資料
回顧性分析2010年1月—2013年12月在該院進行烤瓷牙修復術的96例(172顆牙)的臨床資料。其中男44例,女52例。年齡區間在為22~65歲,平均年齡45.5歲。96例烤瓷牙修復術中,采取鈷鉻合金烤瓷牙的患者有58例(102顆牙),納入鈷鉻合金組,采用鈷鉻合金烤瓷牙修復。采取二氧化鋯烤瓷牙的患者有38例(70顆牙),納入二氧化鋯組,采用二氧化鋯烤瓷牙修復。予以……
