Connection Design

Implants Connections

Dental Tech provides clinicians and dental technicians with different types of prosthetic connections, depending on the implant line: internal and external hexagonal, octagonal, conical and ball connections.

HX3 submerged Implant

The external connection of HX3 dental implants is characterised by a standard 2.7 mm x h 0.7 mm hexagon and by a Ø 4.1 and 5.0 mm base which makes it compatible with the majority of commercially available external hexagon connection implants.

The internal portion of the anti-rotational hexagon has six grooves which are useful for receiving the mounting device which, being conical, is used to remove the implant from the packaging, transfer it to the oral cavity, finally screw it into position in the surgical site.

Horizontal gap

With regard to the external implants with a hexagon connection, in addition to retaining the device in the vertical gap, the horizontal gap between the hexagonal connection of the abutment and implant must be reduced as much as possible, in order to minimize rotation between the devices.
This phenomenon, impossible to prevent with this type of connection, places the prosthetic stability at risk and, above all, leads to premature loosening of the prosthetic screws.

A number of scientific papers, written during the 1990s by Paul Binon in the United States, consider a connection which does not exceed 4° of rotation to be acceptable. Few international companies are able to achieve these results and Dental Tech is one of these. By working to tolerances reduced to a minimum and maintaining tight control over all devices, Dental Tech is able to obtain a minimum and maximum rotation from 0.18° to 0.93° between the parts in question, guaranteeing excellent stability of the connection and prosthetic screws which hold in place.

Submerged Implants: ImpLassic FT3, FT2 Short and ImpLogic® AT and GII

These implants have an internal design containing a 45° chamfer in the coronal portion and a hexagon in the underlying portion.

The connection zone characterised by the 45° chamfer allows the pillar to be positioned with total easiness and security, orients the distribution of the load, avoiding accumulation along the surface of the implant and permits the realization of prosthetic devices with a very low screw stop, a feature which facilitates the work of the technician in the process grinding of the pillars.

The internal hexagon is about 2mm deep and provides optimal stability to the prosthetic abutment, counteracts the lateral forces and safeguards the implant screw from excessive stress.

In summary, we can confirm that the internal hexagonal connection of the ImpLassic and ImpLogic® implants is functional and reliable because they:

 

  • facilitate insertion of the prosthetic devices providing the clinician greater tactile security within the oral cavity;
  • allow a more natural outcome to be achieved, and therefore a better appearance as a result of the low profile of the abutment and of the implant screws;
  • reduce the risk of the implant screw loosening due to the enhanced stability provided by the internal hexagon, thereby increasing the predictability of the prosthetic.

Transmucosal Implants ImpLassic TR2 e TRW2

Transmucosal implants are characterised by a Morse Taper connection which have an internal hexagon. This structure marries the advantages of the conical seal to those of the anti-rotational structures, providing the prosthetic devices with both biological and mechanical stability, without complicating the work of the prosthodontist and the dental technician.

Conical Implant ImpLassic FTP

Conometric connection at 6°, with hexagonal position index and screw through.

It allows a precise and stable coupling of the prosthetic components; precision that has always marked Dental Tech over the years.

Precision of the connection

The scrupulous inspection of every product we manufacture is a well-known hallmark of Dental Tech: the critical dimensions of both implants and prosthetic devices are checked at 100%.

The connection zone between the implant and the abutment plays a fundamental role from a biological point of view; in fact, the width of the gap between the devices described above may lead to peri-implant bone loss. Reducing the gap to a minimum in this point means reducing the area of inflammatory infiltration, one of the major causes of peri-implant bone resorption.
