چکیده

The main objective of this research is to establish a connection between orthodontic mini-implant design, pull-out force and primary stability by comparing two commercial mini-implants or temporary anchorage devices, Tomas®-pin Perfect Anchor. Mini-implant geometric analysis quantification bone characteristics are performed, whereupon experimental in vitro test conducted. With the use CATIA (Computer Aided Three-dimensional Interactive Application) CAD Design)/CAM Manufacturing)/CAE Engineering) system, 3D (Three-dimensional) models segments created. Afterwards, those same imported into Abaqus software, where finite element generated with special focus on material properties, boundary conditions interactions. FEM (Finite Element Method) used simulate test. Then, results structural compared results. contain information about maximum stresses implant–bone system caused due force. It determined that core diameter screw thread conicity factors design have direct impact stability. Additionally, model lower than Anchor, even though endures greater forces, implant implemented still represents more stressed uniform distribution bigger values.

Mechanical influence of thread pitch on orthodontic mini-implant stability.

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...

Evaluation of primary stability of inclined orthodontic mini-implants.

The aim of this study was to investigate the initial stability of mini-implants when placed slanting or perpendicular to the bone surface, and to examine the effects of differences in tractional direction. Titanium mini-implants were inserted into rabbit nasal bones, slanting (60 degrees , 120 degrees ) or perpendicular (90 degrees ) to the bone surface. These implants were then loaded with a f...

Effects of Orthodontic Mini-implant Diameter on Microdamage

Microdamage reduces bone mechanical properties and thus could possibly contribute to implant failure. The objective of this study was to investigate whether the diameter of mini-implants (MI) affects microdamage generation and whether this differs between the mandible and maxilla due to their contrasting cortical thicknesses. Methods: Maxillary and mandibular quadrants of 5 dogs were randomly a...

Finite element analysis of mono- and bicortical mini-implant stability.

OBJECTIVES Loosening and loss rates of monocortical mini-implants are relatively high, therefore the following null hypothesis was tested: 'The local bone stress in mono and bicortically-anchored mini-implants is identical'. MATERIAL AND METHODS Anisotropic Finite Element Method (FEM) models of the mandibular bone, including teeth, periodontal ligaments, orthodontic braces, and mini-implants ...

Evaluation of orthodontic mini-implant placement: a CBCT study

BACKGROUND Optimal positioning of orthodontic mini-implants is essential for a successful treatment with skeletal anchorage. This study aims to compare the accuracy of two-dimensional radiographs with a cone beam computed tomography (CBCT) for mini-implant placement. METHODS An ideal site for mini-implant placement at the buccal interradicular space between the second premolar and the first m...
