The purpose of this study was to ascertain the effect of different abutment height and different taper of abutment on retention force of cemented implant-supported prostheses.
Test specimens consisted of different abutment height group(3 , 4 , 5 , 6 , 7 ) and different
taper(degrees) abutment group(4°, 5°, 6°, 7°, 8°).
The surfaces of abutments and crowns were manufactured and finished by automatic lathe(CNC).
Luting cement(Tokuso Ionomer) was prepared according to the manufacturer’s instruction. And the cylinders were sealed onto the abutments and loaded in compression at 5 for 10minutes. Excess cement was removed from the abutment-cylinder junction and the specimens were stored at room temparature for 24 hours.
Specimens were tested in tension using a universal testing machine.
Within the limits of this study, the following conclusions were drawn:
1. The increase in abutment height result in improvement in retention strength(P<0.05).
2. The increase in taper of abutment result in decrease in retention strength(P<0.05).
3. The decrease in abutment height result in decrease in retention strength, besides has a significantly lower retention strength at 3 abutment height.
4. The increase in taper of abutment result in decrease in retention strength, besides has a significantly lower retention strength at 7° abutment.
