目的论普通金属烤瓷冠与全瓷冠在前牙应用中的比较。方法选择普通金属烤瓷冠的患者(100例)选择全瓷冠的患者(100例),观察两种瓷冠在修复前牙时在临床上的优缺点。结果普通烤瓷冠和全瓷冠在修复前牙时均有美观实用的特点。但是全瓷冠的优点是光泽度好看起来非常的自然,更接近自然牙,也不容易出现牙龈黑线。缺点是内冠的强度不如金属内冠的强度大,造价也比较高。普通烤瓷冠的优点是金属内冠的强度大,价格也较便宜。但是缺点是普通的烤瓷冠例含有镍具有轻微的毒性也易产生牙龈黑线。全瓷冠更适用于前牙。
Aim To compare the application of general metal porcelain crowns and all ceramic crowns in anterior teeth. Methods All patients (100 cases) with all-ceramic crowns were selected, and the clinical advantages and disadvantages of the two kinds of porcelain crowns were observed. Results Common porcelain crowns and all-ceramic crowns have beautiful and practical features when repairing the anterior teeth. However, the all-ceramic crown has the advantage of good gloss looks very natural, closer to the natural teeth, not prone to black line gums. The disadvantage is that the strength of the inner crown is not as strong as the strength of the metal inner crown, the cost is relatively high. Ordinary ceramic crown has the advantage of the strength of the metal crown, the price is cheaper. But the disadvantage is that ordinary porcelain crown cases contain nickel with slight toxicity but also easy to produce gingival black lines. All-ceramic crown is more suitable for the front teeth.
