| Number of platforms |
Two |
One |
| Small diameter implants able to use standard abutments |
No, there are no 2.5mm or 3.0mm diameter two-piece implants |
Yes, 2.5mm and 3.0mm diameter implants. |
| Strength of the implant, 5 million cycle FDA implant
fatigue test |
Unknown. 3.5mm implants are recommended only for replacement of
lower incisors. 4.5mm or greater diameter implants are recommended
for replacement of all other teeth |
425 N for a 3.5mm diameter implant. 3.5mm implants can be used in molar region because of high strength and large surface area |
| Implant stability immediately after placement |
Difficult to achieve good primary stability due to press-fit design |
Excellent primary stability can be achieved in most cases due to screw design |
| Ease of implant removal if implant is not fully seated into prepared osteotomy |
May be difficult because of press fit design |
Easy due to screw design |
| Ease of abutment removal from the implant |
May be difficult, requires the use of forceps |
Easy due to internal thread inside the abutment |
| Osteotomy diameter for implant placement |
Has to be the same as the implant diameter |
Much smaller osteotomy diameter is needed, especially in soft bone |
| Implant level impression technique |
Accuracy of the implant level impression technique is not stated |
Accuracy of the Pick-Up™ impression technique is in 10 microns range for a single restoration |
| Pick-up coping for an implant level impression |
Needed |
Not needed, abutment acts as a pick-up coping |
| Can the vertical "sliding" of the components be predictably reproduced during implant indexing and abutment installation? |
Impossible to achieve due to machining tolerances if a conical or a locking taper connection is utilized |
Yes, to within 10 microns for cement retained restorations; even more accurate with screw retained restorations |
| Is the fit of the screw-retained prosthesis influenced by the machining tolerances? |
Yes, since the fit of the prosthesis depends on the dimensional accuracy between the pick-up coping and the abutment, and between the implant analog and the implant |
No, since a screw-retained abutment is a pick-up impression coping |
