Abstract:Finite element analyses were performed for various shapes of dental implant to study effects on stress distribution generated in the surrounding jaw bone and to determine an optimal thread shape for even stress distribution. It was found that the square thread shape filleted with a small radius was more effective on stress distribution than other dental implants used in the analyses. Additional analyses were performed on the implant with the thread shape obtained from previous analyses for varying other design… Show more
“…In order to define osseointegration between the implant surface and bone tissue, an area of inactive contact was defined between the implant and bone tissue. [1,4] Three different loads were applied to the models to examine their effects on the tension distribution. In this study, the loads applied to the models were as in our previous study, [1] where u is the angle of the load in degrees and F is the magnitude of the load.…”

“…Similarly, Huang et al (2010) suggested that external threads reduce the stress and sliding at the interface. Chun et al (2002) reported that maximum effective stress in the cortical bone is higher in the plateau design as compared to the triangular or square thread designs. In another study carried out by Patra et al (1998), tapered thread design implants were found to distribute higher stress levels in bone as compared to the parallel profile thread.…”
“…These future trends concern the modifications of surface roughness at the nanoscale level for promoting protein adsorption and cell adhesion, biomimetic calcium phosphate coatings for enhancing osteoconduction and the incorporation of biological drugs for accelerating the bone healing process in the peri-implant area. [8] The main objectives for engineering new dental implant surfaces is to improve the clinical Because of the huge number of new Cap coating techniques, we decided to discuss only animal data regarding mechanical testing and/or bone-to-implant contact for PLD (Pulsed laser deposition), sputter coating, IBAD (Ion Beam Assisted Deposition), ESD (Electrostatic Spray Deposition) and biomimetic deposition. [8] PLD (Pulsed laser deposition) [9] PLD is a physical vapor deposition technique and was widely used during the last decade to deposit thin films of materials of technological interest.…”

In principle, PLO technology is based on the irradiation of a solid target by a focalized pulsed laser beam resulting in a gaseous cloud.…”
