Dyna Helix TM
Dyna Helix TM
A Trans-Mucosal implant for all oral endosteal implant indications for the functional rehabilitation of edentulous and partially dentate patients
- TransMucosal polished collar
- suitable for one phase surgery
- no compression zone
- sharp cutting lower edge
The Dyna Helix TM implant is based on root form core with self tapping thread up to the bone level area of the implant. The rough subtractive ART surface creates an optimal micro morphological formation favoring fast bone apposition, whereas, smooth transmucosal part allows using one stage protocol.
Because of the sharp self cutting lower edge of the implant the positioning in height during insertion is easier to manipulate.
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.
The use of several implant diameters and all-fit-all abutments gives an ideal combination of simplicity and reliability. Current concept of Dyna Helix TM implant is based on solid, straight screw cylinder with a 2µm polished collar (2.8mm) extending through the soft tissue.
The basic design of the Dyna Helix TM Implant corresponds to that of the Dyna Helix ST implant.
The absence of the compression zone at the upper part of the implant facilitates surgery for type I or II bone (as defined by Lekholm and Zarb).
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.
Statistical analysis on the available research literature supports the evidence that the bone-implant interface dependents on surface roughness. A specific surface topography with a Ra value between 1 and 1.5μm provides an optimal surface for bone integration.
Biomechanical measurements show that the best results at the moment are realized with a micro/macro roughness varying between 4 and 16μm. Dyna Helix ART implants comply to the above mentioned characteristics by having a Ra value between 1.2 and 1.5 and a micro/macro roughness between 4 and 14 micron. These characteristics are realized by means of a blasting process with different sizes HA particles. An acid etch 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
Fatigue tests proved that this design, even after more than 50 million cycles (10 x ISO norm) did not fracture. The conical shape of the universal fixation screw prevents it from loosening and fracturing if tightened with 30 to 35Ncm. 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.
