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.
