Positioning Templates for Implants

Implant Positioning

Positioning templates serve as aids in implant prosthetics.

They help with the accurate positioning of abutments. In the animation "Positioning Templates", you see a tooth implant anchored in the bone. A transition piece is mounted on this implant. This is called an abutment.

The abutment is the link between the dental crown and the implant. In the animation, you see how the abutment is screwed together with the implant; only then is the crown fastened. The crown is the part you see in the mouth.

There are different types of abutment/implant links. We usually distinguish between two kinds: Those with and those without anti-rotation protection. Anti-rotation protection means that the abutment only lines up with the implant in a certain position.

The advantage of this type of link is easier handling in case of implant-prosthetic work; the disadvantage of this so-called plug connection is the micro-gap between the abutment and the implant.

In cases of plug connections, bone deterioration can frequently be observed – more on that in the video entitled "Tapered Connection". For now, let’s just say that the phenomenon of bone deterioration does not occur in conical connections because there is no micro-gap between the abutment and the implant!

However, handling is a bit more complicated because of the lack of anti-rotation protection. Without anti-rotation protection in the abutments, conical connections require the dental technician to provide the dentist with a positioning template that he can use to transfer the position from the plaster model to the patient’s mouth, so that the abutments are screwed into the correct position at the implant.
