Special Issue Information

Dear Colleagues,

In modern-day dentistry, the success of restorative dental treatments is affected by several clinical and laboratorial parameters.

In former times, the assessment of biomaterials’ restorative mechanical properties was used to predict procedures’ clinical success based on a purely quantitative ranking, without considering the complexity of the oral environment and individual characteristics. Constant properties, such as compressive strength, tensile strength, hardness and toughness, were widely investigated. Nowadays, these mechanical properties are often required to characterize a new material and to understand how it should be implemented in traditional, established materials. Yet, antagonists, the fatigue effect, pH variation and other variables should also be evaluated in order to mimic an unfriendly oral environment.

Precise treatment by dentists can promote durable rehabilitation that will endure chewing loads in the long term. However, errors in dental materials processing, the wrong design of the prosthetic structure, an increased number of defects, high residual stress concentration, wrong geometry, excessive polymerization shrinkage and many others factors can affect the mechanical behavior of dentistry biomaterials.

Several studies have studied the influence of different factors on the biological response with bioengineering tools. Methods including finite element analysis, strain gauge, photoelasticity and digital image correlation are widely used to explore possible solutions in dentistry. Every year, new methods arise and a deeper knowledge of oral biomechanics is achieved.

There is still a lack of data on the clinical and laboratorial parameters that can be controlled to increase treatment performance and the biomechanical response of dental treatments using contemporary dental biomaterials. In addition, digital dentistry has opened up new possibilities, such as chairside workflows; however, these still need to be scientifically established. All of these factors are of great interest for both technicians and clinicians, considering that such findings can be applied to empirically establish adequate dental treatments.

With that in mind, this Special Issue invites you to disseminate your findings on the following themes:

  • Assessment of indirect restorations;
  • Stress generated during chewing loading;
  • Reliability and clinical performance of direct and indirect prosthetic materials;
  • Long-term simulations showing the failure origin and fracture features of failed dental treatments;
  • Evaluation of mechanical response using biomechanical tools in the maxillofacial complex;
  • Procedures to improve the restorations’ longevity and improve patient life quality.

The main objective was to examine the biomechanical behavior of the mandible under standardized trauma and to develop models of biomechanical responses when the mandible is subjected to various simulated impacts. A homogenous model based on the bone’s average mechanical properties was used. To simulate external loads on the mandible, forces on the chin, forces in an anteroposterior direction, and forces from the basilar edge were applied. To simulate mandibular biomechanics, we employed a model created in the ANSYS v19.0 software. The skull with the temporomandibular joint (TMJ) from the Grabcad website was used as the geometric mandibular model. We attempted to simulate the stresses developed in the mandible by impact forces. The amount of force (F) corresponded to the fall of a five-kilogram body (the head), from a height of two meters (F = 6666.7 N). The impact force was applied perpendicular to an arbitrary surface of an area of 10−3 m2. Impact on the chin region and lateral impact on the mandible, from the basilar edge to the gonion were examined. The investigated clinical situations were mandibular complete dentition; jaw with missing mandibular molars; missing third molar and first and second premolars; missing canine, third molar, first and second premolars, and complete edentation. In a normal bite, the highest stress was on the TMJ area. In case of impact on the chin, in complete edentation, a mandibular fracture occurred; in case of impact on the gonion, all stress values exceed the limit value above which the mandible in the condyle area may fracture.
