Vibrational Force on Accelerating Orthodontic Tooth Movement: A Systematic Review and Meta-Analysis

European Journal of Dentistry (2022)

Amin Akbari Vaibhav Gandhi Jie Chen Hakan Türkkahraman Sumit Yadav

Abstract This study aimed to systematically gather and analyze the current level of evidence for the effectiveness of the vibrational force in accelerating orthodontic tooth movement (OTM). This systematic review was conducted using three electronic databases: Scopus, PubMed, and Google Scholar until March 2022. The search was done through the following journals: European Journal of Orthodontics, American Journal of Orthodontics and Dentofacial Orthopedics, The Angle Orthodontist, Progress in Orthodontics, and Seminars in Orthodontics. Human or animal studies that have evaluated the effect of vibrational force on the rate of OTM were selected. A meta-analysis was performed for the rate of canine movement per month. Database research, elimination of duplicate studies, data extraction, and risk of bias assessment were performed by authors independently and in duplication. A fixed and random-effect meta-analysis was performed to evaluate the effect of vibrational forces. A total of 19 studies (6 animal and 13 human studies) that met the inclusion criteria were included. Meta-analysis was performed based on four human clinical trials. Three out of four studies showed no significant difference in the rate of canine movement between vibrational force and control groups. The limitation of this study was the small sample size and significant heterogeneity among the studies. Although vibrational forces have been shown to accelerate OTM in experimental studies, the results are inconsistent in clinical studies. The inability to apply desired peak load to the targeted teeth may be the main factor in inconsistent clinical outcomes.

Finite Element Modeling for Orthodontic Biomechanical Simulation Based on Reverse Engineering: A Case Study

Research Journal of Applied Sciences Engineering and Technology (2013)

Yunfeng Liu Nan Ru Jie Chen Sean Shih-Yao Liu Wei Peng

In order to improve the validity and feasibility of the solid model of oral tissue, a new method is provided based on reverse engineering. Biomechanical simulation with FEM is an important technique for orthodontic force analysis and evaluation, as well as treatment design. As the base of FEM simulation, the solid geometrical models of oral tissue including tooth, Periodontal Ligament (PDL) and alveolar bone are difficult to construct through conventional solid modeling methods because the oral models are very complicated in geometry and topology which are generally represented as triangular meshes. But in many cases, solid model is necessary for FEM performing. So how to construct the solid model of oral tissue with good quality and efficiency is a problem should be faced and solved in orthodontic biomechanical simulation. Aiming at this problem, reverse engineering modeling is adopt to transfer triangular meshes to four-sides surface model and together with techniques of medical image processing, three dimensional triangular meshes calculating, surface fitting and solid modeling, the solid geometrical model of oral cavity for FEM analysis is constructed from CT (computerized tomography) images. With a simulation case of rat molar movement test, the whole procedure of solid modeling based on reverse engineering and some main techniques are presented and the validity and feasibility are proved also by the simulation results.

Biomechanical validation of an artificial tooth–periodontal ligament–bone complex for in vitro orthodontic load measurement

The Angle Orthodontist (2012)

Zeyang Xia Jie Chen

ABSTRACT Objectives: To develop an artificial tooth–periodontal ligament (PDL)–bone complex (ATPBC) that simulates clinical crown displacement. Material and Methods: An ATPBC was created. It had a socket hosting a tooth with a thin layer of silicon mixture in between for simulating the PDL. The complex was attached to a device that allows applying a controlled force to the crown and measuring the resulting crown displacement. Crown displacements were compared to previously published data for validation. Results: The ATPBC that had a PDL made of two types of silicones, 50% gasket sealant No. 2 and 50% RTV 587 silicone, with a thickness of 0.3 mm, simulated the PDL well. The mechanical behaviors (1) force-displacement relationship, (2) stress relaxation, (3) creep, and (4) hysteresis were validated by the published results. Conclusion: The ATPBC simulated the crown displacement behavior reported from biological studies well.

Quantification of three-dimensional orthodontic force systems of T-loop archwires

The Angle Orthodontist (2010)

Jie Chen Serkis C. Isikbay Edward J. Brizendine

To demonstrate the three-dimensional (3D) orthodontic force systems of three commercial closing T-loop archwires using a new method and to quantify the force systems of the T-loop archwires.An orthodontic force tester (OFT) and a custom-made dentoform were developed to measure force systems. The system simulated the clinical environment for an orthodontic patient requiring space closure, which included measurement of three force components along, and three moment components about, three clinically defined axes on two target teeth. The archwires were attached to the dentoform and were activated following a standard clinical procedure. The resulting force system was measured using the OFT.The force systems of the T-loops on the teeth were 3D. Activation in one direction resulted in force and moment components in other directions (side effects). The six force and moment components as well as the moment-to-force ratios in the clinically defined coordinate system were quantified.The commercial archwires do not provide force systems for pure translation. Quantification of the force system is critical for the selection and design of optimal orthodontic appliances.

[Influence of different restorations on the fracture resistance of endodontically treated premolars with minor loss of dental defect].

PubMed (2015)

Xiaoxia Qiu Xiaoping Zhang Jie Chen Yue Chang

To evaluate the influence of 3 different restorations on the fracture resistance of endodontically treated premolars with minor loss of dental defect in order to direct clinical design.Seventy-two recently extracted intact and single-rooted human mandibular premolars for orthodontic reason were collected and randomly divided into 3 groups (group A, B, C, n=24). Each group was respectively prepared into 1/3 defect of occlusal surface (group A), 1/2 defect of occlusal surface (group B) and 1/3 defect of proximal-occlusal surface model (group C). Then each group was divided into 3 subgroups with one restored with a light-curing composite resin(group A1, B1, C1), one restored with cast metal full crowns following a light-curing composite resin (group A2, B2, C2), and one restored with fiber posts and resin cores and cast full crowns after teeth preparations (group A3, B3, C3, n=8). Static loading tests were performed on each specimen until cracked.Fracture strength was tested and fracture patterns were examined. The data was analyzed using SPSS17.0 software package.The fracture resistance of subgroup A2 was different when compared with subgroup A1 and subgroup A3. In group B and C, the fracture resistance of teeth in subgroup B2, B3, C2 and C3 were significantly higher than that in subgroup B1 and C1. There was no significant difference in the fracture mode of 3 restorations in group A, B and C.A composite resin combined with cast metal full crowns can be used as the first choice to restore endodontically treated premolars with proximal-occlusal 1/3 defects and occlusal defects that do not surpass 1/2 dimension of occlusion.
