目的讨论金属烤瓷的临床修复。方法查阅文献资料并根据个人临床经验进行归纳总结。结论金属与瓷粉相匹配是金一瓷修复体成功的关键,同时,也是金一瓷结合的关键。因此,应严格控制烤瓷合金与瓷粉的热膨胀系数,瓷粉的热膨胀系数应略小于烤瓷合金。烤瓷完成后,要控制冷却速度,防止出现急冷瓷裂。活髓牙固定修复,牙体制备较少时,对牙髓的影响不大。随着人们对牙齿美容的重视以及金属烤瓷冠桥修复技术的普及,前牙活髓烤瓷冠以及活髓牙作为烤瓷桥固位体的应用日益广泛。
Objective To discuss the clinical repair of metal porcelain. Methods Access to literature and summarized according to personal clinical experience. Conclusion The matching of metal and porcelain powder is the key to the success of gold-porcelain restoration. At the same time, it is also the key of gold-porcelain combination. Therefore, the coefficient of thermal expansion of porcelain alloy and porcelain powder should be strictly controlled. The thermal expansion coefficient of porcelain powder should be slightly smaller than that of porcelain alloy. After the completion of porcelain, to control the cooling rate, to prevent the emergence of cold cracking porcelain. Live pulp fixed dental pulp, tooth preparation less, little effect on the pulp. With people’s attention to the beauty of the teeth and the popularity of metal porcelain crown and bridge restoration techniques, the use of anterior pulp living porcelain crowns and live pulp teeth as a ceramic bridge retainer is increasingly widespread.
