ABSTRACT
Objective To observe the effect of all-ceramic crowns and metal ceramic crowns in the application of full denture prosthesis. Methods 86 patients who received full denture prosthesis in the Yunnan Transportation Center Hospital of Yunnan Province from January 2012 to September 2012 were chosen as the research object. According to the order of patients admission tag,patients with the odd tag were as the control group,patients with the even were as the observation group, and 43 patients in each group. Patients in the control group received metal ceramic crown repair, and patients in the observation group received all-ceramic crown repair. Patients in the two groups were followed up for 12 months to 24 months, and the black line on the gingival cervical margin, periodontal damage and porcelain crowns crack were compared between the two groups. Results The cervical margin black line ratios in the observation group and the control group were 2.33%(1/43) and 18.60% (8/43), the difference was statistically significant ( <0.05) . 11.63% (5/43) of patients in the observation group appeared cracks and fracture, compared with the control group of 2.33% (1/43), there was a statistically significant difference ( <0.05) . Conclusion Compared with etal ceramic crowns, all-ceramic crowns in full denture prosthesis have less injury in periodontal tissue and weaker anti-crack intensity, so the clinicians should choose the all-ceramic crowns based on the patients' indications.
