- The old metal braces were much more visible than today's tooth-colored or translucent alternatives.smiling pretty blonde girl image by Scott Slattery from Fotolia.com
Ceramic braces are an aesthetically pleasing option for the patient needing corrective measures to straighten or properly align the teeth. The first generation of ceramic braces were only used in cases where a lighter force over a longer period of time could correct the orthodontic problem. Today's ceramics are stronger due to the addition of a metal slot that allows the braces to be moved along the metal wire connecting them without causing as much friction to the ceramic brackets cemented to the teeth. - The main advantage of ceramic brackets is that they are less visible than the old metal brackets that were traditionally bonded to the teeth. The archwire connecting them is also much less evident. The ceramic brackets do not stain but the clear elastic ties that are used to attach the wire to the braces do. Fortunately, the ties are replaced with each appointment-usually about once a month. Most ceramic brackets are made of either polycrystalline or monocrystalline alumina. The difference between the two is mainly one of color.
- Monocrystalline braces have a clear, translucent appearance. These braces are sometimes called monocrystalline sapphire. Rather than trying to match tooth color, these braces allow the natural color of teeth show through. For this reason, monocrystalline braces are preferred by patients who regularly experience staining of their teeth through the habitual use of cigarettes or coffee. Between cleanings, the contrast between the non-staining braces and the stained teeth is less pronounced.
- Polycrystalline braces are more whitish or tooth-colored. This form may be a better alternative for younger patients where staining of the enamel through food, drink or age is far less likely. The brackets blend in with the color of the teeth and maintain their invisibility between adjustments.
- The first generation of ceramics was more brittle and often resulted in more repair appointments. Ceramics can be more expensive than regular braces. Orthodontists sometimes absorb the cost difference but some may charge up to $1,000 more for ceramics than for the old metal alternatives. Ceramic is harder than tooth enamel so use in patients where teeth may be damaged through ceramic to enamel contact is avoided. Ceramic brackets can be difficult to remove and may need to be ground off if a piece breaks and sticks to the tooth. A diamond bur fitted to a grinding drill can fix the problem but may add to patient time and costs. Newer ceramics have largely mitigated this problem.

A new ceramic bracket, not yet available in the United States, was recently introduced at an orthodontic convention in Germany. The Opal Bracket is made of polycrystalline with a high portion of glass fiber. The new braces feature a self-ligating built-in hinge door that fits over the arch wire and eliminates the need for ligature elastics. A PDF file explaining the new product is available but it is written only in German. ( See Resources 1) Translation of the fact sheet may be worthwhile for the information afforded orthodontists and their patients in North America.
