“…In the vertical plane, molar hook exhibited extrusion of anterior teeth, whereas implant positions showed intrusion Rokutanda et al . [ 20 ] studied to assess the movement pattern of the anterior teeth using power arms and miniimplant. En-masse retraction with sliding mechanics using a force of 250 g parallel to the occlusal plane was applied to the power arm hooks with elastic chains.…”

Engineering has not only developed in the field of medicine but has also become quite established in the field of dentistry, especially Orthodontics. Finite element analysis (FEA) is a computational procedure to calculate the stress in an element, which performs a model solution. This structural analysis allows the determination of stress resulting from external force, pressure, thermal change, and other factors. This method is extremely useful for indicating mechanical aspects of biomaterials and human tissues that can hardly be measured in vivo. The results obtained can then be studied using visualization software within the finite element method (FEM) to view a variety of parameters, and to fully identify implications of the analysis. This is a review to show the applications of FEM in Orthodontics. It is extremely important to verify what the purpose of the study is in order to correctly apply FEM.

“…22 Height of implant placement and the length of the power arm, play a critical role in determining the biomechanics and the nature of the tooth movement produced. [23][24][25] Based on these considerations we used a medium-length hook (8-10 mm) which was placed distal to the maxillary canine to achieve the nearest possible point and line of action of force in relation to C r es of maxillary dentition. Kuroda et al stated that the major drawback of placing intra-alveolar implants is the high risk of root approximation that obstructs the tooth movement and is already touching the implant, even before reaching to the desired position.…”

The correction of skeletal malocclusions in orthodontics has always been a contest for clinicians, especially in non-growing individuals, and often necessitates the distalization of maxillary or mandibular skeletal bases. To accomplish this, diverse treatment modalities have been employed by researchers, and the most recent one is the use of extra-alveolar bone screws such as Infra-zygomatic Crest (IZC) implants. Unlike conventional methods such as extraction and orthognathic surgery, this technique is an effective and efficient treatment alternative for predictable total arch distalization in borderline surgical cases, without interfering with the root movements and with minimal dependence on patient compliance. For achieving the displacement of teeth in a bodily controlled manner, an appropriate direction and magnitude of force must be carefully chosen. Therefore, this case report attempts to measure the amount and pattern of maxillary molar distalization using Infra-zygomatic Crest (IZC) implants with long power arms as a workable treatment option, in an 18-year-old female patient with a skeletal Class II pattern, with no extra mini-implants in the anterior region for intrusion.
