Mechanical Evaluation of Tatum's Dental Implants System
Objectives: To investigate Tatum's dental implants system under compressive and fatigue behavior of 4 different implant design systems using the accelerated lifetime test.
Methods: For compressive testing, a total of sixty screw implants were used in this study:
¥ Fifteen 3.5 D x 13-mm / Integrity Tapered Implants (ITI) 1 piece implant-abutment connection.
¥ Fifteen 3.5 D x 13-mm / Integrity Tapered Implants (ITI) 2 pieces implant-abutment connection.
¥ Fifteen 3.5 D x 13-mm / Unipost™ Screw implants.
¥ Fifteen 3.5 D x 13-mm / ITO One Piece Tapered Implant-abutment connection.
For fatigue testing, a total of forty-four screw implants were used in this study:
¥ Eleven 3.5 D x 13-mm / Integrity Tapered Implants (ITI) 1 piece implant-abutment connection.
¥ Eleven 3.5 D x 13-mm / Integrity Tapered Implants (ITI) 2 pieces implant-abutment connection.
¥ Eleven 3.5 D x 13-mm / Unipost™ Screw implants.
¥ Eleven 3.5 D x 13-mm / ITO One Piece Tapered Implant-abutment connection.
For compressive testing: The compression load was applied to each angulated abutment by a unidirectional vertical platform and loaded with compression at a rate of 0.02 inch per minute until failure.
For fatigue testing: The fatigue load was applied with 3 increment stages on each angulated abutment by a unidirectional vertical platform and loaded with fatigue forces for 100.000 cycles of 10% (stage 1) of the UTS obtained previously. Following by stage 2 and 3, with 200.000 and 300.000 cycles respectively with 20% and 40% of the UTS obtained previously.
Results: In the compressive Failure (UTS) results:
- ITI implants can take the most UTS(n), more than ITO and Unipost.
- Post hoc analysis found No sig diff between ITO and Unipost
- Max Elastic (n) was sig different across all groups.
From the Fatigue results:
- Unipost was sig different from all other groups between stage 1 and 2,
- Between stage 2 and 3, there is no significant difference between ITI and the other groups, otherwise Unipost and ITO are different from one another.
In the failure mode evaluation it was observed identical combined bending of the implant-abutment Connection and screw.
Conclusions: The strength of the Integrity Tapered Implant (ITI) design is much higher than the Unipost and ITO implants Design.
