OBJECTIVES This study investigated the surrounding bone stress and the implant-bone interfacial sliding of implant designs and implant sizes of immediately loaded implant with maxillary sinus augmentation by using three-dimensional (3D) non-linear finite element (FE) analysis. METHODS Twenty-four FE models including four implant designs (cylindrical,(More)
PURPOSE This study investigated how the primary stability of a dental implant as measured by the insertion torque value (ITV), Periotest value (PTV), and implant stability quotient (ISQ) is affected by varying thicknesses of cortical bone and strengths of trabecular bone using synthetic bone models. MATERIALS AND METHODS Four synthetic cortical shells(More)
BACKGROUND Strain gauge analysis and finite element (FE) simulations were used to estimate the bone strain and micromovement at the bone-implant interface (BII) for platform switching and different diameters of a single, immediately loaded mandibular implant. METHODS Four models were created, including 5-mm-diameter implants assembled with abutments that(More)
PURPOSE The biomechanical effects of different strengths of grafted bone, bicortical anchorage, and dimensional alterations of a dental implant with maxillary sinus augmentation were investigated. MATERIALS AND METHODS Sixteen finite element (FE) models that included five implant lengths, two implant diameters, and grafted bone with two levels of(More)
This study aims to evaluate the inclinations of right and left sides the mandibular fossa in Asian population using computed tomography (CT) images and determine its effects according to the parameters of gender, age, and asymmetry. CT images of the heads of 198 Asian subjects [95 females aged 44.2 ± 20.7 years, range 11–88 years; and 103 males aged 44.5 ±(More)
OBJECTIVE This study evaluated the effect of bone quality on the stability of and stress in the artificial temporomandibular joint (TMJ) condylar prosthesis as well as on the stress and strain distributions in the bone. STUDY DESIGN Three-dimensional finite element models of the mandible and an artificial TMJ condylar prosthesis using 3 screws were(More)
BACKGROUND/PURPOSE Although exhaustively studied, the mechanism responsible for tooth support and the mechanical properties of the periodontal ligament (PDL) remain a subject of considerable controversy. In the past, various experimental techniques and theoretical analyses have been employed to tackle this intricate problem. The aim of this study was to(More)
PURPOSE Bone stress and interfacial sliding at the bone-implant interface (BII) were analyzed in zirconia and titanium implants with various thread designs and interface conditions (bonded BII and contact BIIs with different frictional coefficients) for both conventional and immediately loaded treatments. MATERIALS AND METHODS A total of 18 finite element(More)
Experiment with rapid prototyping technique and validation finite element model was performed to evaluate the biomechanical behavior of an immediately loaded mandibular implant. Also, 18 finite element models of six implant designs and three surface roughnesses with anisotropic bone material properties were analyzed to compare the bone stresses and the(More)
Hinokitiol is a natural component isolated from Chamacyparis taiwanensis. It has anti-microbial activity, and has been used in oral care products. The minimal inhibitory concentration (MIC) and minimal microbicidal concentration (MMC) of hinokitiol against MRSA, Aggregatibacter actinomycetemcomitans, Streptococcus mutans, and Candida albicans were(More)
