早在70年代,Rochette就报告用树脂粘接以贵金属铸造有孔固位体义齿修复,随后Howe等报告用有孔的非贵金属支架,作前牙固定局部义齿(FPD),用树脂粘接临床上获得成功。Thompson等为树脂粘接修复体开展了蚀刻金属技术,使铸造修复物固位力增加。本文对酸蚀金属树脂粘接FPDS进行了临床评价。本研究选择患者标准 (1)桥基牙无龋病及修复体或非受累面有小的修复体;(2)咬合接触关系不紧;(3)桥基牙排列适当;(4)牙齿无松动;(5)有适合的酸蚀釉质面。共选33例患者,男15例,女18例,
As early as the 1970s, Rochette reported on the use of resin-bonded, cast-in-place, precious metal cast denture prostheses. Then Howe et al. Reported using a perforated non-noble metal stent as an anterior fixed partial denture (FPD) On the success. Thompson et al. Performed an etched metal technique for resin bonded prostheses to increase the retention of the cast restoration. In this paper, the clinical evaluation of acid-etching metal bonded FPDS. This study selected patient criteria (1) bridge abutment caries-free and repair or non-involved surface with a small prosthesis; (2) the relationship between the occlusal contact is not tight; (3) the abutment teeth arranged properly; Loose; (5) there is a suitable acid etching enamel surface. A total of 33 patients were selected, 15 males and 18 females,
