Over the past two decades, using clear aligners to realign or straighten teeth has gained popularity. A particular type of compact, transparent aligner used in orthodontic practice goes by the brand name Invisalign. Even though Invisalign aligners are clear, they fit over the teeth firmly and are considerably less obvious than the wires and brackets of conventional braces. Many dental problems can be treated with Invisalign, including various forms of underbite, crossbite, overbite, open bite, filled-in teeth and teeth gaps. A session with an orthodontist is the first stage of the procedure, during which the mouth and jaw will be captured in 3-D. Using this as a guide, a strategy for repositioning the teeth into their proper positions is devised. The aligners must typically be worn for 20 to 22 hours per day. The degree to which Invisalign works depends on how complicated spacing or biting problems are. Consult Dr. Aneesh Katyal for Invisalign treatment cost in Gurgaon at AK GLOBAL DENT.
