Titanium Shock absorber

The natural, elastic environment of the mouth has always been the direct opposite of the rigidity of dental components; with all the resultant consequences. Until today!

With the Titanium Shock Absorber (TSA), Bonecare markets an innovative abutment for bridges that provides a natural mouth and chewing sensation for your patient. The very first biomechanical abutment in the world, resulting in added comfort for patient and practitioner.

The human body is a dynamic entity. Introducing rigid
elements such as dental implants, may cause issues:

  • Insensitive patients will bite down harder due to the absence of proprioception. This results in chipped porcelain, fractured structures, acrylic teeth, screws …
  • Tension/stress in the jaw and/or joints
Left: situation with a standard intermediary abutment. Right: the dynamic TSA abutment.

TSA is the only dental abutment that biomechanically supports the natural chewing function. It simulates the functioning of the periodontal ligament and allows for a micromovement. In return, the patient will experience the implant-supported suprastructure as a natural given.



A fixed design of the top of the abutment, only for screw-retained constructions.


The spring allows the abutment to return to its original position every time.


The variable base of the abutment connects to the implant and is available to be fitted to most conventional implant platforms and connections.


The abutment’s interior is completely filled with a layer of dental elastomer. This layer allows a micromovement of +- 20 micron.

The natural chewing function is a dynamic process: anatomic structures such as bone, the jawbone joint (TMJ) and the periodontal ligament all have a certain elasticity which absorbs and distributes the chewing force.


This absence of periodontal ligament in implants (ankylosis) prevents any physiological mobility. This evidently results in mechanical overburdening, and an increased fracture risk for the implant, the abutment, the screw as well as the restoration. Furthermore, this overburdening is discussed as an etiological factor for the occurrence of peri-implantitis.


The TSA abutment with its unique resilient function will decrease the risk of these issues. The mobility of the TSA abutment even micromassages the underlying soft tissue.


For an implant-supported bridge, connected to natural teeth, the TSA abutment will provide a synchronous movement between the periodontal ligament and the rigid implant, resulting in a continuous even distribution of the chewing force on completely different connectors. In particular cases, the number of implants can be reduced, omitting expensive and time-consuming bone augmentation.


Compared to the fixed and rigid connection of the bridge to dental implants, the use of TSA in implantsupported bridges, not connected to natural elements renders a more natural feeling for the patient.


Pressure tests (1.200.000 cycles) in a moist and warm environment demonstrate that this resilient function is sustainable.


The TSA abutment warrants a higher chewing comfort, healthier gingiva, an improved bone quality and a wider indication area.


TSA guarantees a patient-friendly solution. This unique and revolutionary concept is available to fit most conventional implant platforms, in varying heights. For the treating dentist, this abutment is very easy to apply as well.

Proscan is the distributer of the TSA abutment in the Benelux. www.proscan.be

What are the dimensions of a TSA abutment?

The dimensions of the TSA abutment are:

What warranty conditions apply to a TSA abutment?

Bonecare grants a 10-year-warranty to a TSA abutment when used properly. The implant warranty is transferred from the manufacturer.

What is the maximum divergence between 2 implants in order to be able to use a TSA?

The maximum divergence between 2 implants in order to use a TSA is 20°.

Is there an angled TSA abutment?

There is no angled TSA abutment. With use of the digital database, however, it is possible to provide an angulated screw channel in the superstructure.

What is the benefit of working on abutment (TSA) level?

Some of the benefits of working on abutment level are: preservation of the biological seal at impression and installation of prosthetics, ease of use because the platform is placed at tissue level, cleanability …

What are the contraindications for TSA?

Contraindications are:

  • Patients whose medical condition does not allow for dental implants.
  • Patients under 18 years of age (treatment not advisable until bone formation is complete.)
  • Patients for whom the number and position of the implants is not suitable.
  • Patients who are allergic to Ti 6-AI 4V (90% titanium, 6% aluminium, 4% vanadium) and silicone.
  • Cases that require a rigid construction (e.g., overly-sensitive gums).
  • Cases where the divergence between the implants exceeds 20°.
  • Patients with blood and cardiovascular diseases, peri-implantitis, periodontitis, decompensated diabetes, drug or alcohol abuse, chronic therapy with high doses of steroids, anticoagulant therapy, radiotherapy treatment.
Is it possible to sterilise a TSA?

The TSA abutment as well as the impression coping, interface and tools are supplied non-sterile and need to be sterilised before use with a patient. This requires the following procedure:

Gravity Autoclave Pre-Vacuum Autoclave
Temperature 134°C 134°C
Exposure Time 3 minutes 30 minutes
Dry Time 3 minutes 20 minutes
What is the required torque value to fix a TSA?

The torque value for the TSA abutment is indicated on the label of the packaging.

What is the interface height for TSA?

The height of the interface is 6.25mm. This can be taken into account in the height available for the prosthetic part.
