【摘要】：目的:探討幾種表面處理方法對氧化鋯修復(fù)體粘接強度的影響,為提高氧化鋯修復(fù)體的粘接力提供依據(jù)。方法:加工10mm×10mm×2mm釔穩(wěn)定氧化鋯瓷坯60件,根據(jù)表面處理方法不同將試件分成噴砂組、硅涂層組、Z-PRIME Plus組、噴砂+Z-PRIME Plus組、噴砂+硅涂層組和硅涂層膠+Z-PRIME Plus組,每組10件。使用通用型粘接劑Scotchbond~(TM) Universal制作氧化鋯-樹脂粘接樣本,在37℃水浴中儲存24h后采用萬能力學(xué)試驗機測試其剪切強度,體視顯微鏡記錄樣品斷裂模式,各組斷裂樣品隨機抽取1件,在掃描電子顯微鏡下觀察其表面形貌。結(jié)果:Z-PRIME Plus組試件所測得的剪切強度明顯高于其他組(P0.05)。斷裂模式觀察,粘接破壞主要出現(xiàn)在噴砂、硅涂層、噴砂+硅涂層和硅涂層+Z-PRIME Plus組試件中。噴砂+Z-PRIME Plus組試件混合破壞4例,噴砂+硅涂層組試件混合破壞8例;各組試件均未出現(xiàn)內(nèi)聚破壞。掃描電鏡下觀察,噴砂、Z-PRIME Plus和噴砂+Z-PRIME Plus組試件斷裂面發(fā)生在粘接劑-氧化鋯界面,硅涂層、硅涂層+Z-PRIME Plus組試件斷裂面發(fā)生在硅涂層-氧化鋯界面,噴砂+硅涂層組試件斷裂面部分發(fā)生在硅涂層-粘接劑界面。結(jié)論:Z-PRIME Plus用于氧化鋯表面預(yù)處理可以明顯提高其與樹脂的粘接強度。
[Abstract]:Objective: To study the effect of several kinds of surface treatment on the bonding strength of the repair body of the oxidized silicon oxide, and to provide the basis for improving the adhesive force of the oxygen-oxidizing agent. Method:60 pieces of 10-mm,10-mm and 2-mm high-pressure stable oxidation-resistant porcelain were processed, and the test pieces were divided into sand-blasting group, silicon coating group, Z-PRIME Plus group, sand-blasting + Z-PRIME Plus group, sand-blasting + silicon coating group and silicon-coating adhesive + Z-PRIME Plus group according to the surface treatment method. using a universal adhesive, Scotch-(TM) Universal, to make an oxidized-resin adhesive sample, storing the sample in a water bath at a temperature of 37 DEG C for 24 hours, testing the shear strength by using a universal mechanical testing machine, recording the fracture mode of the sample according to a stereomicroscope, and randomly extracting one piece of fracture samples in each group, The surface morphology was observed under a scanning electron microscope. Results: The shear strength of Z-PRIME plus group was significantly higher than that of other groups (P0.05). The fracture mode was observed and the adhesion failure mainly occurred in the sandblasting, silicon coating, sandblasting + silicon coating and the silicon coating + Z-PRIME Plus group test piece. In the sand-blasting + Z-PRIME Plus group,4 cases were mixed and destroyed, and 8 cases were mixed and destroyed by the sand-blasting + silicon coating group, and no cohesive failure occurred in each group of test pieces. The fracture surface of the test piece of the sand-blasting, Z-PRIME Plus and the sand-blasting + Z-PRIME Plus group was observed under the scanning electron microscope, and the fracture surface of the test piece on the adhesive-oxidation interface, the silicon coating, the silicon coating and the Z-PRIME Plus group occurred on the silicon coating-oxidation interface, The part of the fracture surface of the sand-blasted + silicon coating group occurred on the silicon coating-adhesive interface. Conclusion: Z-PRIME Plus can obviously improve the bonding strength of Z-PRIME plus the resin.
