Special Issue Information

Dear Colleagues,

In order to promote innovation in the field of dentistry, it is necessary to develop not only conventional dental materials but also an emergent dentistry by incorporating advanced science and technology. In addition to biomaterials, the development of bioengineering technologies including proteins, cells, and genetic manipulation and their application to medicine are currently attracting significant attention. The development of new materials and technologies and their development into treatment methods is expected to lead to new breakthroughs and innovations in future dental practice. In this Special Issue, we invite various papers on the application of bioengineering to dentistry.

Objectives: Hybrid implants commonly exhibit decreased corrosion resistance and fatigue due to differences in compressive residual stresses between the smooth and rough surfaces. The main objective of this study was to investigate the influence of an annealing heat treatment to reduce the residual stresses in hybrid implants. Methodology: Commercially pure titanium (CpTi) bars were heat-treated at 800 °C and different annealing times. Optical microscopy was used to analyze the resulting grain growth kinetics. Diffractometry was used to measure residual stress after heat treatment, corrosion resistance by open circuit potential (EOCP), corrosion potentials (ECORR), and corrosion currents (ICORR) of heat-treated samples, as well as fatigue behavior by creep testing. The von Mises distribution and the resulting microstrains in heat-treated hybrid implants and in cortical and trabecular bone were assessed by finite element analysis. The results of treated hybrid implants were compared to those of untreated hybrid implants and hybrid implants with a rough surface (shot-blasted). Results: The proposed heat treatment (800 °C for 30 min, followed by quenching in water at 20 °C) could successfully homogenize the residual stress difference between the two surfaces of the hybrid implant (−20.2 MPa). It provides better fatigue behavior and corrosion resistance (p ˂ 0.05, ANOVA). Stress distribution was significantly improved in the trabecular bone. Heat-treated hybrid implants performed worse than implants with a rough surface. Clinical significance: Annealing heat treatment can be used to improve the mechanical properties and corrosion resistance of hybrid surface implants by homogenizing residual stresses. Full article

The design of dental implants has undergone minor modifications over the years to reduce possible future complications that may arise from implant rehabilitation. One critical element from a clinical point of view is the implant connection. Given this, the team of authors of the present study decided to biomechanically analyze the effect of implant connection obtained in a possible implant fracture through a systematic review of the published literature. To this end, a search was conducted in the PubMed and Scopus databases. Only finite element studies carried out in vitro and simulation studies were included, discarding clinical studies and related reviews. A total of 19 studies were obtained for analysis and complete study. The conical type is the connection design that demonstrates the best biomechanical behavior. However, there was also significant heterogeneity in the design of the studies, which translates into a substantial source of bias, as well as different types of specific designs within the conical connection. In conclusion, it was established that the design of the connection seems to play a fundamental role in the fatigue resistance of the implant when subjected to load. However, more studies are needed to determine the most optimal specific design. Full article
