Introduction: Among different non-invasive approaches for determining the stability of the implant within the bone is to use a dynamic device called Periotest®.It is designed to provide objective measurement of tooth mobility. The aim of the present study is to evaluate the stress transfer and stability in short and standard dental implants using Periotest®</sup...

The aim of this study was to evaluate the effect of pitch distance on the primary stability (PS) of orthodontic mini-implants (MIs) in artificial bone. Twenty experimental MIs were allocated to two groups, according to their geometric design: G1 (30o X 0.6 mm) and G2 (45o X 0.8 mm), and inserted into artificial bone of different densities: D1 (0.32 g/cm3) and D2 (0.64 g/cm3). The maximum insert...

The purpose of this experiment was to investigate whether low-intensity pulsed ultrasound (LIPUS) irradiation can inhibit dentoalveolar ankylosis in transplanted rat teeth. LIPUS irradiation (the pulsed ultrasound signal had a frequency of 3.0 MHz, a spatial average intensity of 30 mW/cm2, and a pulse ratio of 1:4) was performed on the face over the re-planted teeth of rats for 4 weeks. After t...

This study aimed to investigate a causal relationship between the stability of orthodontic anchor screws (screws) and the degree of their proximity to the root (root proximity) using mobility test device (Periotest) and cone-beam computed tomography (CBCT). In total, 165 (diameter 1.6 mm; length 8 mm) screws in 58 patients (average age, 24.4 ± 8.5 years) were evaluated. After screw placement, C...

background and aims: plasma rich in growth factors (prgfs) has been recently proposed as an aid to enhance regeneration of osseous and epithelial tissues in oral surgery. the purpose of this study was to determine the effect of local application of platelet rich plasma (prp) on implant stability measured by periotest. materials and methods: a total of 24 implants were placed in mandible of 12 l...

The objective of this study was to analyze the efficacy and correlation between clinical and histologic parameters used to evaluate oral implants. After extraction of the premolars and a healing time of 4 months in 16 Dutch goats, four Brånemark implants were placed in the maxillary left and right premolar regions. After a healing time of 6 months, followed by another 4 months with the permucos...

The Periotest percussion force acting on a dental implant was estimated by assuming a mass-spring-dashpot model of the implant-bone system constructed on the basis of a clinical experiment. A theoretical value of about 10 N, comparable to hitherto reported experimental values, was obtained for an osseointegrated implant of about 1 g. The percussion force would probably be smaller for a heavier ...

Purpose: This study aimed to evaluate the changes in damping capacity according striking and bone conditions of implants placed a porcine rib using two devices (Periotest; Medizintechnik AnyCheck; Neobiotech).Materials Methods: In first experiment, 20 implant fixtures were on ribs connected at three healing abutment heights (3.0, 4.0, 5.0 mm). The capacities measured different vertical angles (...
