INGEO was involved in a lot of biomechanics articles. This term refers to the behavior of a prosthesis (hip, knee, teeth, spine, shoulder, hand) during its normal operation in the human body.
INGEO initiated several collaborations about scientific research on biomaterials and biomechanical behavior of implants (especially dental implants).
Here are presented some italian research and publications by the PhD Luigi Paracchini concerning biomechanic.
| Different geometric patterns of pacifiers compared on the basis of finite element analysis |

This study was carried out with file purpose to show on a virtual model of oral cavity the mechanical behaviour of different kinds of pacifiers with . different pressure levels that can be likened to a condition of the rest and deglutition.

The efficacy and reliability of an implant design to biocompatibly transfer the occlusal forces on its prosthetic restoration to its surrounding bone is a significant engineering challenge. The BICON® short implant is an example of a time proven geometric design that successfully transfers the occlusal forces on its prosthetics to its surrounding bone by appropriately integrating the following features: a bacterially-sealed, 1.5 degree locking taper abutment to implant connection and a sub-crestally placed, sloping shouldered implant with a plateaued tapered root form body.

| 3D finite element analysis to detect stress distribution: Spiral family implants |
Top |
Spiral family implants are a root-form fixtures with increasing thickness of tread. This characteristic gives a self-tapping and self-condensing bone properties to implants. To study spiral family implant inserted in different bone quality and connected with abutments of different angulations a Finite Element Analysis (FEA) was performed.

Biomechanical optimization is an important objective in the design of dental implants. Finite element analysis (FEA) has become an increasingly useful tool for predicting the biomechanical stress on an implant and the surrounding bone. The components in a dental implant-bone system are geometrically complex. The use of FEA in implant biomechanics offers many advantages over other methods when it comes to simulating the complexity of clinical situations. FEA facilitates predictions of stress distribution in the contact area between implant walls and cortical bone and between the apical aspect of the implants and trabecular bone. Although the success rates of some implant systems have been high, implant failures do occur.

3D model of the bone and dental implant |
Important studies have been done concerning the biomechanics of the mandible. In particular, the evaluation of the stress, according to von MISES, in the system with the presence of mandibular teeth have been achieved. In the two pictures below you can see the stress that exchange the lower and the upper dentition.
