“…Dental implants have become increasingly common as a method for replacing missing teeth in recent decades [1][2][3][4]. However, while some studies have reported an implant success rate as high as 78-100% [5], other studies have indicated that single tooth replacement failures may occur for a variety of reasons [6], including implant surface, implant design, and bone quality factors [7] and early bone loss in the dental implant region [8].…”

“…The bone material property also has an important effect on the stress distribution in dental implant systems. However, the accurate modeling of bone-related organs using finite element modeling (FEM) methods is challenging due to their inherent inhomogeneous and anisotropic characteristics [1,4,37,58]. As a result, almost all previous studies consider the implanted bone to be isotropic, homogeneous, and linearly elastic [3,4,25,41,[59][60][61][62][63].…”

Variations in the implant thread shape and occlusal load behavior may result in significant changes in the biological and mechanical properties of dental implants and surrounding bone tissue. Most previous studies consider a single implant thread design, an isotropic bone structure, and a static occlusal load. However, the effects of different thread designs, bone material properties, and loading conditions are important concerns in clinical practice. Accordingly, the present study performs Finite Element Analysis (FEA) simulations to investigate the static, quasi-static and dynamic response of the implant and implanted bone material under various thread designs and occlusal loading directions (buccal-lingual, mesiodistal and apical). The simulations focus specifically on the von Mises stress, displacement, shear stress, compressive stress, and tensile stress within the implant and the surrounding bone. The results show that the thread design and occlusal loading rate have a significant effect on the stress distribution and deformation of the implant and bone structure during clinical applications. Overall, the results provide a useful insight into the design of enhanced dental implants for an improved load transfer efficiency and success rate.

“…For this experiment foam blocks with a thickness of 10 mm, a width of 15 mm, a length of 15 mm, and density of 0.64 g/cm 3 (40 pounds per cubic foot = 40 pcf) were used. Polyurethane (PUR) foam blocks have been commonly used in experimental studies replacing cadaver or animal bone specimens [4,7,[12][13][14][15][16][17]. According to Schim [18] and Horn [19] polyurethane foam is a good alternative for human cancellous bone as it displays similar mechanical properties and may be used as a medium for implant testing.…”

The aim of this experimental study was to verify thermal diffusion differences, by measuring the maximum temperature achieved with different drill shapes. Synthetic bone blocks of type I density made from solid rigid polyurethane (PUR) foam were used to perform the drilling procedures. The experiment was conducted at three different rotation speeds: 800, 3000 and 5000 rpm. Conical drills (with and without an internal cooling hole) were compared with horizontal drills and disc drills. The temperature during drilling for implant bed preparation was estimated with the use of thermocouples and an infrared (IR) camera. The temperature during drilling with disc cutters for lateral basal implants did not exceed 33 ∘C and the temperature decreased in proportion to higher drill speed. The results indicate that the tested design is safe and will not cause bone overheating.
