Are there any other alternatives to metal rail-tracks?
Apart from the traditionally used metal brackets, semi-transparent brackets made of ceramic or reinforced plastics are gaining popularity. Clear braces are more aesthetically pleasing as they are less visible at a distance. The brackets may be made of ceramic material or plastic. Ceramic material is very hard and can lead to wear of opposing teeth. They are also more expensive than metal braces. Plastic braces are not as durable as metal or ceramic ones and require addition care. If you need total invisibility there are lingual brackets to consider. With recent advances in technology, teeth can now be straightened with a series of clear, plastic, removable aligners without metal wires or brackets. Teeth will move - little by little, week by week - by a series of aligners until they have straightened to the final position the orthodontist has prescribed. These sequential plastic aligners (Invisalign®) can align teeth, but they cannot correct significant bite discrepancies. Your orthodontist would recommend the best alternatives, most suitable for your type of malocclusion.
