Retentive properties of a threaded split post with attachment sleeves cemented with various luting agents

摘要: Abstract This study determined the retention, in pounds, of Nos. 1 through 3 stainless steel attachment sleeves for threaded split post system cemented with various cements. Post heads and matching were also sandblasted compared attachments not sandblasted. Four luting agents selected, zinc oxyphosphate cement (ZOP), three brands composite resin (CRC). The experiment was divided into two parts; part 1, samples treated, 2, Retentive values recorded a universal testing machine. A 2 × 4 factorial three-way analysis variance used to compute effects sandblasting, sleeve type, agent. No statistical differences sandblasted, regardless nonsandblasted No. Panavia CRC had significantly greater retention than All-Bond or ZOP. There no despite type For 3, ZOP CRC. However, there difference between sandblasting sleeve. Mean loads substantially
