Two or three in one?
The conventional implants build up from three separate parts: the implant, the abutment, and the crown. The reason is, following the implant’s insert, for the healing (bone integration) period, the doctor closes up the implant with a healing screw, and then sews the affected gum part. After the 3-6-month period, he replaces this healing screw with an abutment, then he takes a print, and based on that, the dental technicians make the crowns, bridges.
On the other hand, the Bi-cortical (Swiss) implants build up from two parts: the implant (which already has the abutment) and the crown parts. This is possible, because in this case, there is no need for a 3-6-month “healing period”, in which we close up the implant. After inserting the Swiss implants, making a print can happen immediately, and after a few dasys the patient receives the new crowns and bridges.
Which one’s which?
So, how can we determine easily which implant means which type? The difference is perceptible to the eye:
- Conventional implants are shorter, the Bi-cortical is longer.
- The conventional implant is screwless all the way, while the Bi-cortical is only on its end.
- The conventional implant is cone-shapes, while the Bi-cortical is cylindrical around its middle part.
- The conventional implant’s abutment is removable, while it’s fixed on the Bi-cortical.
Why are they different in length?
Like we mentioned in the listing, conventional implants are shorter than Bi-cortical implants. The reason is in the bone: Conventional implants lock in the outer hard bone and below that, in the spongy bone layers, while the longer Bi-cortical reaches even the second hard bone layer. Thanks to this, even at inserting it, before the ossification process, a stable holding can be achieved.
The screw thread is also different
Conventional implants are threaded all the way on their surface. This has several reasons. On one hand, the screw thread automatically increases the surface of the implant, so the receiving bone can connect to it on a bigger area. On the other hand, thanks to the threads, the implant receives a more stable holding before the osseointegration (bone integration) process occurs.
In contrast, only the bottom of the Bi-cortical implant is screwless, because this stabilizes it in the second hard-bone layer.
Is the sinus lift treatment avoidable?
As long as the patient doesn’t have sufficient bone to accept the implants around the sinus, there are two opions:
- Before inserting the conventional implants, the patient takes part in a so-called sinus lift treatment, where they fill his sinus bone substance with bone-replacing materials. This material needs 3-6 months to develop into bone, so inserting the implant can only begin after that.
- In case we use Bi-cortical implants, we can avoid the sinus area, and the sinus lift treatment as well. Bi-cortical implants are pliable, this way we can stabilize the tooth replacement below the sinus without touching the sinus.
To sum up, conventional implants and Swiss Bi-cortical implants differ in the following standpoints:
- From how many parts do they build up (two or three)
- How long does the whole treatment take (more than 3 months or a week)
- Their length is also different
- In which bone layer do they stabilize
- Where are they screwless
- Is the sinus lift treatment necessary or is it avoidable
