Stomatologiia (Mosk). 1994 Apr-Jun;73(2):54-6.
A total of 262 patients aged 32 to 58 were examined and 246 patients aged 30 to 60 were treated. Of the 944 cermet crowns examined complications were found in 88 (9.34%). Ceramic fractures occurred in 20 crowns, inflammatory processes in the gingiva developed in 22 cases, functional overexercise of the periodontium in 21, failure of cement fixation in 18, apical periodontitis in 7 cases. The causes of these complications are analyzed and measures to prevent them worked out. If all preventive measures were adhered to in the treatment of 246 patients fitted with dentures, complications occurred three times more seldom (in only 3.14% of cases).
共检查了262名年龄在32至58岁之间的患者，并治疗了246名年龄在30至60岁之间的患者。在检查的944个金属陶瓷冠中，发现88个（9.34%）出现了并发症。20个冠发生了陶瓷骨折，22例出现牙龈炎症，21例出现牙周功能过度活动，18例出现粘结固定失败，7例出现根尖周炎。分析了这些并发症的原因并制定了预防措施。如果在治疗246名佩戴假牙的患者时坚持所有预防措施，并发症的发生率会降低两倍多（仅为3.14%）。
