1) In guided surgery there is no way to irrigate the drills. How does Toltac® in order to allow it?
> Toltac® does it because there is no obstacle between the handpiece's irrigator and the drills, as in the normal freehand surgery.
2) Is it Toltac® precise and safe?
> For a reliable implant planning the CBCT must be correct, the scan of the cast models must be precise, and their matching must be accurate. Since Toltac® system does not modify the usual software's workflows, this allows the same level of prediction as in the other systems of guided surgery. On the other hand, the mechanics of Toltac® allows visual control, the drills are guided before their first contact with the bone and the Toltac® guide is much longer than a normal sleeve for guided surgery. Furthermore, diversely from other conventional guided surgery systems, Toltac® allows the use of safety drill stops, they can ensure that the drill will not be able to go deeper than planned: the drill is stopped at the planned depth by the contact with the bone, not by the contact with the sleeve, which, due to a template's wrong positioning, could be closer than expected to the bone and produce a deeper site preparation. Nevertheless, the operator must ALWAYS take into consideration adequate safety margins as in all procedures of implant surgery, and refrain from using Toltac® or other ways of guided surgery if there is not enough space between the planned implant's position and critical anatomical structures.
3) To whom is Toltac® System addressed?
> Toltac® System is addressed to all customers of freehand surgery they wish an help in the implant positioning without distort their operating habits. Toltac® allows them to test guided surgery also for a single intervention: there is no need to buy a whole dedicated surgical kit. Of course it is available also for all customers of conventional guided surgery looking for a solution of the problems they can experience, mainly when the patients don't open the mouth enough to insert the drills into the sleeves.
4) May Toltac® System be used also with transmucose implants with neck wider than the intraosseous portion?
> Yes, Toltac® has been particularly tried with transmucose implants of this kind, with neck wider than intraosseous portion, even though it may be used also with the other kinds of implants.
5) May the system be used also with tilted implants?
6) I am not familiar with planning software, can I still use the Toltac system?
> Yes. HCS Italy offers a complete consulting service from implant planning to delivery of the Toltac® template. Just send HCS the DICOM data of the CBCT and the stl files of the optical scans made according to the Toltac® protocol, then the HCS specialists will do the rest. If you already have a planning set up in Codiagnostix™ or Implant3D™ you can send it to HCS for completion and design of the Toltac® template. Toltac® specialists will do the rest. If you already have a planning set up in Codiagnostix™ or Implant3D™ you can send it to HCS for completion and design of the Toltac® template.
7) Are the Toltac® components CE certified?
> Yes. Toltac® drivers and Toltac® guides have CE certification as Class 1 medical devices
8) Is it possible to have a Toltac® template if one has not followed the Toltac® data acquisition protocol?
> In all cases, when the customer sends them to HCS, the data are checked by HCS specialists. Planning is only carried out if the data are of sufficient quality to make them compatible with the Toltac® protocol; in some circumstances, even CBCT performed without a diagnostic template may be compatible and therefore allow planning according to the Toltac® System, but in order to be more probable that the Toltac® service could be provided, it is strongly recommended to follow it.
