Finite element analysis: Is it justifiable?

In recent years, more specifically in the months, I have received a large number of articles to review that rely on finite element method (FEM) or analysis (FEA) study different matters related orthodontics. Some these are excellent works, but vast majority very low quality and present neither proper justification for using FEA nor correct execution. Thus, write this editorial give some insight researchers clinicians who might be planning attempting which FEM is used as an tool. The first point want emphasize strongly objective logic considering FEA. Clear needed regarding how results would affect every day clinical practice. Several papers reviewed justify their use by such has not yet been performed examine particular appliance, bracket, wire. This strong because forces applied mouth major factor considered; if new appliances similar mechanics, then why need analysis? Another issue authors acknowledge there already studies published topic, they another one modify 1 small aspect (eg, change assumed material properties) treatment modalities. By no surprise, common trend conclusions what other found respective studies. One most rationales application appliance modality proven successful practice, even presenting proving this. When outcome understood, should seriously consider could truly add our understanding problem improve Our apply it solve complicated mechanics-based issues hard answer clinically findings help clinician determine changes fix causing problems manufacturers product reduce side effects. If tangible influence protocols, combination 2, ask themselves conduct will really elucidate. simply, “this hasn't done yet,” worthwhile? Beyond surrounding applications, also whether skillset analysis. complex mathematical tool primarily analytical exact solution possible. Although absolutely case with many orthodontics, thus likely requiring FEM, automatically assume straightforward. A range properties, boundary conditions, mesh density, numerical can all output significantly. Just user gets from simulation, does mean accurate. Recent advances software made much friendly, double-edged sword. facilitated solving allows those less skilled methods obtain while necessarily was reached. article Romanyk et al1Romanyk D.L.
