Dyna Helix DC Implant

A Two phase bone level implant with one phase surgical option

  • ideally suited for maxilla type III and IV bone
  • compression zone
  • excellent primary stability
  • platform switching
  • rounded lower edge

The design

The Dyna Helix DC implant is a tripartite cylinder screw designed to give secure mechanical fixation and load distribution in all clinical situations. It is a two- stage, screw type implant that can be used in one-stage surgery if the criteria for one stage surgery are met. It achieves sufficient primary stability in class IV bone whereas in class I, dense cortical bone guarantees safe and a-traumatic insertion. Dyna Helix DC implant has a root form Dual Core with self tapping thread.

The core of the implant allows for bone condensation during insertion supporting the primary stability in all bone types and stimulates the healing process. The rounded lower edge of the implant makes the positioning of implants above the nerves more secure and surgical procedures of closed sinus lift easy and a-traumatic. 

The use of the Cortical reamer and pre-tapping is necessary when, especially in the cortical bone, there exists the risk of overheating or creating too much stress in the surrounding bone. The lower part of the treads are designed more horizontally. Because of this design the axial forces are transferred more vertically to the alveolar bone.

Based on the new principles to prevent bone resorption the implants are totally treated with the ART surface. The biological width principe is respected by means of the V-shape connection to the abutment coined as platform switching. The uncoated collar gives a smooth transition to the abutment. The use of several implant diameters and all-fit-all abutments gives an ideal combination of simplicity and reliability.

The system

The Dyna Helix Implant system combines the successful features in Implantology

  • root shaped with straight self tapping thread
  • high primary stability in all bone qualities
  • early or immediate loading option
  • platform switching
  • ART roughened titanium surface

The special thread shape results in a combination of forces providing a mechanical fixation and load distribution. This will contribute to primary stability of the implant.

The Dyna Helix Implant System gives you an option for use in one or two phase surgery. Excellent primary stability in all bone qualities will be achieved by the implant characteristics. It gives the option to be used in standard, early or immediate loading indications.

The bone level implants have the platform switching concept. Insertion is performed without mounting device by means of a special octa driver.

To realize the best mechanical and biological properties in combination with ideal surface treatment properties Dyna Helix implants are made in the medical Titanium grade 5 ELI.

Research shows that best results are realized with a micro/macro roughness by having a Ra value between 1 and 1.5. Dyna Helix® ART implants comply to the above mentioned characteristics by having a Ra value between 1 and 1.4. These characteristics are realized by means of a blasting process with different sizes HA particles. An acid etched washing process ensures a clean surface with an optimal morphology.

1 conical abutment connection

Precise closure of the abutment connection by the use of an octagon with press-fit

  • press fit internal octagon
  • conical abutment connection
  • one universal crown and bridge conical fixation screw
  • each abutment fits all implant designs & diameters

At the same time this conical connection provides a stable fit in the implant, which makes the whole construction very solid and generates the ideal distribution of the applied forces. Dynamique loading tests according to EN ISO14801:2016 show appropriate levels of fatigue strength. The conical shape of the universal fixation screw prevents it from loosening and fracturing if tightened with 35 Ncm before the final prosthetic treatment. This provides high stability and makes the whole system self-centering. Due to friction forces, only a small amount of the applied torque will be transferred to the thread of the screw resulting in a considerable tension relaxation. This, in combination with the conical connection, makes it almost impossible to overload and break the screw during normal physiological use.

1 instrument cassette

The standard Dyna Helix instrument cassette is used for all Dyna Helix implants. So during operation it is possible to choose the type of implant without opening other instrument cassettes.
