Orthodontics, the oldest discipline of dental specialty concerns with the treatment of malocclusion both dental and skeletal. Although etiology of malocclusion is multifactorial, genes do have influence on this condition, beside their role in mechanism of tooth movement and unwanted sequel like external root resorption following orthodontic treatment. This short communication will focus the issue on role of gene in various conditions which have paramount effect either on the etiology of malocclusion or mechanism by which tooth movement occurs. Human genome project and future advancement in genomic medicine will help us in clear identification of conditions causing mutation and the unsolved zigzag puzzle of molecular interaction can be solved.

Orthodontic wires, which generate the biomechanical forces communicate through brackets for tooth movement. In the rational selection of wires for a particular treatment, the orthodontist should consider a variety of factors, that includes the amount of force delivery, the elastic range or spring back, formability or ease of manipulation, the need for soldering or welding to assemble an appliance, in vivo corrosion with release of metal ions and the biocompatibility concerns for the patient. To accomplish this objective, four archwire alloys were only available in contemporary orthodontics, that is stainless steel, cobalt chromium, nickel titanium, and beta titanium. Orthodontic wires have evolved from noble metal alloys to the newer esthetic archwires. The choice of most suitable wire for treatment requires adequate knowledge about the biomechanical properties of various orthodontic wires.Research in the field of orthodontic biomaterials have accelerated the development of newer archwire materials with superior quality and biomechanical properties. Here we have discussed about the evolution of archwires and general properties of the wires till date.

We are living in an era where time is money and money is time. So even in the field of dentistry, orthodontic patients are now looking for optimal results with minimal effort as quickly as possible. To be a successful orthodontist, one must not only provide the best dental and facial results possible but also deliver esthetic soft tissue results under shortest duration of time and efficiency. Thus, with the advancement in technology, laser has become more and more important in the field of orthodontics as well.
