HYLOCK® is an implant system conceived under three main premises:

1

High stability

both intraosseous and of the implant-abutment prosthetic connection to give immediate stability and also in the long run

2

Adaptation to any type of clinical situation

this means a wide range of diameters and lengths and a wide variety of prosthetic options.

3

Ease of use

both in surgery and in prosthesis, and both for the experienced professional and for those who start in this field

The Hylock® System arises from the idea of creating an implant that provides great primary stability in an easy and predictable way. To this end a highly self-tapping design has been created, with very easy penetration into any type of bone due to its progressive conical core shape and its very sharp and separated threads. On the other hand, and in order to be able to apply a high torque during the insertion, a very robust and deep connection has been incorporated into this implant with wide rails that dissipate mechanical stress very well, configuring a Torx type section

Based on scientific evidence

According to the clinical study of Dr. Paolo Trisi (JOMI 2011; 26: 837-849) regarding the direct rela-tionship between torque, primary stability and secondary stability, a high primary stability will lead us to consistently obtain an even higher secondary stability, increasing the percentage of bone-implant contact (BIC) in the medium and long term.

Ease of use

A very important aspect that has been taken into account is to ease the task to the dentist, both surgeon and prosthodontist. The implant is very tolerant with the osteotomy and allows easy pene-tration in any type of bone.

In the prosthetical field, both platforms NP and SP have exactly the same active upper part on the abutment, for both cemented or screw retained options, in a way that we can have the same pros-thetical possibilities no matter the diameter of the implant.

Wide variety of lengths and diameters

3.0
3.25

6.0

The system has two types of platform connections, NP and SP, which have the same length but different width.

  • The 3.0mm, 3.25mm and 3.5mm diameter implants have the narrow platform, NP.
  • The 4.0mm, 4.5mm, 5.0mm, 5.5mm and 6.0mm diameter implants have the standard platform, SP.
  • The narrow connection NP has a golden prosthetical color to ease the identification.
  • The prosthetical options on both platforms are the same, as a result, the implants of 3.0mm and 6.0 diameter have the same restorative capacities, both in cemented, screw-retained or just retained by clip options using our patented Fixpeek® system.

The connection:

Hylock® incorporates an internal connection of hybrid type sealed with a double parallel cone, es-pecially patented for this system.

The conical sealing of the abutment on the implant and the screw on the abutment have the same degree of convergence. This parallelism gives absolute watertightness to the system, avoiding completely the colonization of bacteria inside the implant.

This connection guaranties that the implant-abutment assembly behaves as a whole unit in front of mechanical stress, providing a perfect forces transmission. This together with the double friction of the cones, avoids screw loosening, thus solving one of the most common problems for both den-tists and patients in cases with unitary implants.

This connection provides multiple clinical advantages:

1

Indexation

It allows a much easier placement-indexation (prosthetic manipulation) by guiding the abutment through the rails long before the blockage of the cone.

2

Uniform settlement

Likewise, the prolonged orientation provided by this hybrid part causes the abutment to descend to the implant in a perfectly axial way, so that the settlement of the cone occurs completely uniformly

3

Impression prints facilitated in divergent implants.

Unlike other non-hybrid connections, Hylock® makes it possible to make direct impression to the implant head in cases of extreme divergence. Since the impression coping can index the implant being more external in it, facilitating then its exit in the drag of the silicone with the prints. This is very important infull arch restorations which are often very divergent (All on four and All on six). Because if we want to make custom abutments we will need a direct implant print.

4

Insertion torque

Together with the rails, Hylock® allows to apply a very high insertion torque without fear of nicking the connection. This characteristic is in line with the highly self-tapping form of the implant, which therefore requires high torque in order to achieve a high primary stability.

5

Short and long term stability

The column shape of the rails provides more restrictions to the movement than the classic hexa-gon, giving more stability to the connection. Together with the friction and antirotation created by the cone, they make the assembly extremely stable.

The screw:

Its cylinder-conical shape gives it several advantages:

1.- Distribution of stress.

The conical shape of settlement over the pillar, and parallel to the cone of the implant, causes the assembly (implant-pillar-screw) to behave like a block, supporting and distributing the lateral forces of shear with respect to a flat settlement.

2.- Anti-screw-loosening.

The parallel double cone lock connection, by creating more friction over the abutment than the standard planar surface avoids further loosening, which is a usual nightmare in clinical practice, for both dentist and patients.

3.- Easier insertion.

The shape of the thinned diameter screw in the central part facilitates entry into the angled chim-neys, allowing to screw in very angled implants.

External part:

Composed by two well differentiated parts:

  • 1An internal nucleus or body of the implant with progressive conicity.
  • 2An external part formed by the turns of the thread, whose thickness of cut increases progressively. The most apical part of the thread has threads whose edge is very sharp. In this same area there are also four oblique vertical cuts that form a helix that facilitates stability and penetration in all types of bone.

The surface:

However good the design of the implant may be, without a proper preparation of the surface
(cleaning, high energy, high wettability) it will be completely useless.

To avoid compromising the long-term success of the implant, nothing better than a highly contrast-ed surface, such as the SLA.

Our implants are made of grade V ELI titanium, Ti6AL-4V. This alloy is characterized by offering the following properties:

  • Very high mechanical resistance (895Mpa, four times higher to the degree I titanium).
  • Precision of the milling
  • Resistance to corrosion
  • Resistance to abrasion
  • Resistance to crack propagation

State of the surface

The SLA surface (sandblasting followed by double acid etching) is nowadays the highest contrasted in the market. It has been used in Implantology for more than twenty years.

Optimal roughness

The processes of sandblasting and acid etching the surface of the implant, allows to obtain optimal roughness values that make the adhesion of fibrin easier. Making it more tenacious to fibrine -surface detachment, and facilitating that way the process of osseoconduction and significantly re-ducing the time of final osseous integration.

The ability of the surface to retain the fibrin filaments during the contraction phase of the clot allows the osteoblasts to migrate towards the surface of the implant. Next, they reproduce, manufacturing new bone that is in contact with Titanium from the beginning (Contact Osteogenesis)

The roughness obtained with the sandblasting etching processes, together with the plasma treat-ment, reduces the percentage of carbon present, thus achieving a surface with a very low surface tension, a cells friendly surface.

Wettability

This allows the blood to wet the entire surface of the implant during its insertion, facilitating the cas-cade of events that lead to the stabilization of the clot.

The image shows how the blood rises through the turns of the implant during the insertion, due to the great wettability.

Surgical Box

The surgical box is both simple and complete, and incorporates the “drilling stops” It is intuitively distributed and has all the necessary elements to undertake any type of clinical situa-tion. The professional feels comfortable from the start.The included torque wrench has a maximum torque of 100 Ncm, according to the philosophy of the system. The milling cutters are of the cylindrical-conical type, with four cutting blades along their entire length to facilitate a progressive osteotomy without jolts. The surgical box in its upper right part has the drilling stops that ensure depths of 7, 8.5, 10, and 11.5 mm and are attached to the stem of the bur (immediately below the active part).

TECHNICAL SPECIFICATIONS OF THE HYLOCK® SYSTEM

  • Highly self-tapping design

    It favors the penetration in the bone in an atraumatic way, even applying high insertion torques. This helps to achieve high stability rates from the beginning.

  • Progressive penetration

    The very sharp design of the threads prevents bone trauma and favors the subsequent vasculari-zation. The four-bladed helix at the apex provides an atraumatic penetration in the bone and at the same time stabilizes the implant during the insertion. Which is extremely practical in immediate im-plantology procedures.

  • Less stress in the bone

    Even with high insertion torques, bone stress is minimized. Since the implant cuts but does not compress, and maintains an excellent vascularization around it. This means that the mechanical stress transmitted by the prosthesis on the implant is dissipated in the bone in a more homogene-ous way, favoring long-term survival.

  • Step of unfolded thread

    The thickness of the turns from the apex gradually increases up to an unfolding point. This provides added vertical stability, very important in type IV soft bones.

  • Platform switching automatically incorporated.

    The incorporated change of with between abutment and implant in all diameters, allows the biological width to remain unchanged from the initial placement. This avoids bone resorption, with all the aes-thetic and functional advantages that this entails.

  • A very extensive range of sizes

    HYLOCK® offers many diameters (from 3.0mm to 6mm) and lengths (from 7mm to 17mm), that way the dentist can fulfill any patient´s clinical situation.

  • High primary stability

    The design of the implant, with the turns very horizontally and vertically separated from its nucleus, provides excellent short and long-term stability. Since it allows the bone to be imbricated in the vol-umetric perimeter of the implant providing a stability much higher than it would have been if it was a cylinder. This is critical in the survival of the implant when short or small implants are used.

  • Facility of use

    The HYLOCK® implant is very tolerant with the osteotomy due to its design, it is capable of provid-ing a great stability, even with great differences in the drilling

  • Mechanically reliable

    Robust and reliable connection, prepared to withstand high insertion torques or forward-back ma-neuvers without any deformation. This connection is at the same time is deep, precise, and avoids loosening.
    This connection ensures that the implant-abutment assembly behaves as a hole set in front of me-chanical stress as a whole, providing a perfect transmission of forces. This, together with the dou-ble friction of the cones, avoids loosening, thus solving one of the most common problems that both dentist and patients have in cases with unitary implants.

  • Sealing and watertightness of double parallel cone.

    The conical sealing of the abutment on the implant and that of the screw on the abutment, both with the same degree of convergence. This parallelism provides an absolute seal to the system, avoid-ing colonization of bacteria inside the implant.
