The News of Dental Implant

If you have one or more missing teeth, or have broken or decayed teeth that might be beyond repair, implants are usually the answer. If you’re uncomfortable with your dentures, partial denture, or bridge, you could benefit from dental implant technology.

In the past, patients with insufficient bone or who had certain health conditions or habits were not considered candidates for implants. Advances in diagnostics and bone reconstruction have made it so that most patients can receive implants.

Up until fairly recently, most dentists relied on procedures such as root canals, bridges and the use of dentures as the best methods of fixing lost or broken teeth. While these methods have always been effective in some cases, for many people they did not provide a viable, long-term solution. Root canals( endo equipment ) and bridges fail over time and dentures have proven to be uncomfortable and cumbersome to wear and use for many people. It is only through the development of methods, tools and technology that a better way to replace damaged or lost teeth has come along.

One of the biggest advantages of an dental implant is that it restores full chewing power. Most patients can’t tell the difference between their natural teeth and the implant tooth( dental implant motor ). They can eat with it completely normally, and they can brush and floss normally as well.

Where there is no tooth, the jaw bone in the empty space deteriorates due to lack of stimulation. If no implant is placed in the first year of losing a tooth, that bone area loses 25% of its volume, and bone loss continues over the years.

Dentures can even accelerate bone loss as they often become loose, and then rub against the bony ridge, gradually wearing it away. Because an implant replaces the root as well as the tooth, and chewing is restored to normal, it provides the needed stimulation for natural bone growth.

Dental Curing Lights and Your Vision

When dentists or any member of a dental team uses dental curing lights, protective eyewear or a shield to cover the light-curing unit (LCU) is a must. The Orbiter allows dental professionals to cure resin-based composite restorations and sealants in a manner that provides safety for your eyes and convenient treatment.

Light with wavelengths of less than 500nm, also known as near ultraviolet or blue light, has been shown to cumulatively harm the eye’s retina and decrease the ability of the macular region of the retina to provide sharp vision. This light may also be connected to the formation of cataracts.

The retina is located at the back of the eye and covers about 65 percent of the interior surface. Rods and cones are the photosensitive cells in the retina that convert light energy into signals that travel along the optic nerve to the brain. In senile or age-related macular degeneration, the eye’s macula begins to breakdown and can lead to blurriness or dark areas in your central vision. The macula is a small area in the retina that allows you to see fine details clearly.

Resin-based restorations and dental sealants are cured by light in the 370nm to 470nm range. Reliable research shows that this area below the 500nm range can be harmful to vision. Therefore, the use of appropriate eye protection or a shield when operating a dental curing light is essential. Any protection should filter out the majority of light that is less than 500nm.

The filter material that is used in The Orbiter blocks approximately 99.8 percent of harmful near ultraviolet and blue light. In addition, because of The Orbiter’s counterweight design, the shield constantly readjusts itself to the upright position as you change the angle of the unit to cure different surfaces or different restorations. Thus, The Orbiter positions itself so that the user does not need to interrupt his or her work to adjust the shield.
