The Use of Dental Air Polisher

Dental air polisher was developed in the early 1970’s as a technique for fast and efficient removal of extrinsic stains, plaque and other soft deposits from the teeth. It comprises a stream of pressurized air carrying specially graded particles of a mild soluble abrasive usually sodium bicarbonate, mixed with a stream of water.

Dental root form implants are manufactured from a highgrade titanium alloy, the surface of which consists of a micro layer of titanium oxide. The implant surface can also be treated by plasma spraying, acid etching, sandblasting or coated with HA. The removal of plaque and calculus deposits from these implant surfaces with Dental Instruments designed originally for cleaning natural tooth surfaces can result in major alterations to the delicate titanium oxide layer. Altering the surface topography by roughening the surface may enhance calculus and bacterial plaque accumulation.

Resulting scratches, cuts or gouges may also reduce the corrosion resistancy of titanium, and corrosion and mechanical debris can accumulate in the surrounding tissue. The aim of procedures for debriding dental implants should be to remove microbial and other soft deposits, without altering the implant surface, and thereby adversely affect biocompatibility. Increased surface roughness can lead to an increase in bacterial accumulation and resultant soft tissue inflammation. Because of the critical nature of the implant/soft tissue relationship, metal ultrasonic scaler tips, hand scalers or curettes should not be used as they have been shown to significantly alter the titanium surface.

If inflammation becomes established in the periimplant tissues, pocketing and bone loss can develop, which if left untreated, will result in the loss of the implant. Clinicians worldwide are advocating surgical regenerative procedures to restore or repair lost periimplant tissues.These techniques attempt to achieve the repair or regeneration of lost periimplant tissues,and rely on making the implant surface biocompatible with the healing tissues. This implies a detoxification of the previously infected implant surface.

Airpolishing with the H.S.T polishing system is an efficient and gentle means of debriding the implant surface to aid the removal of bacteria and bacterial toxins. The unique H.S.T. polishing system has been shown to result in no damage to the surface of titanium implants or transmucosol elements. An initial report has indicated that the HA coating can be removed with the H.S.T. polishing system.Removal of HA is sometimes indicated when the HA coating has been seriously compromised by the inflammatory process.

The Meaning of Dental Sandblasters

Dental health has improved dramatically with falling rates of tooth decay and attention has now shifted to the needs of an ageing population, with an increased emphasis upon aesthetics – that is, having a full set of sparkling white teeth. Therefore, dental technologists spend much of their time in the lab creating cosmetic dental prostheses such as crowns and implants. This work creates dust and chemical fumes. Without proper protection, exposure to these may risk the health of the dental technologist.

An advance in adhesive dentistry has resulted in sandblasting, to increases micro-retention, being performed as a routine procedure. Instead of wearing a path from the patient’s chair to the office lab to clean excess cement from a patient’s temporary or loosened permanent crown ,or for sandblasting the fitting surface of a crown, bridge inlay or veneer, the procedure is a half- turn away, thanks to the new breed of sandblasters and hookup options.

The uninterrupted patient/doctor exchange is especially beneficial with anxious adult patients – no need to cut the reassuring golf story short for a trip down the hall, leaving the patient alone. Standard hookup kits allow, with a simple male disconnect, access to the dental unit’s air source through the female port. Many dentists have sandblasters with quick disconnects in every operatory, and these space- efficient wonders tuck easily into a drawer.

Dental laboratory equipment–sandblasters are used to increase bond strength by divesting the casting investment and increasing effective surface area as well as polishing the surface of castings. Sandblasters that are used in dental laboratories are enclosed and often operate through a vacuum or via air compressor. Dental laboratory sandblasters are operated via foot pedal and often feature gloves to work through, this keeps everything contained. Sandblasting media can be Aluminum Oxide, glass beads or Silicone Carbide grit. Be sure to choose a dental laboratory sandblaster that employs proper dust retraction.

Dental sandblasters can also be intraoral and used in dental operatories. Also referred to as air abrasion, dental sandblasters can be used instead of dental drills in various procedures. Intraoral dental sandblasters have a variety of angled tips allowing the technician to reach any part of the mouth. These tips should be autoclavable. Be sure that if a product is used intraorally, that it is FDA approved.

What Should You Know of Dental Curing Light

In the dental field, a dental curing light can use ultraviolet or visible light, depending on what it is designed for. Both dentist and patient need to wear eye protection to limit damage to the retina for even the 20 seconds to a minute that the light is in use during rapid curing, and the light needs to be well maintained so that it will work properly and effectively. It’s also important to use the right curing light for the right resin product; many lights are designed to handle a range of resins safety.

Using a curing light accomplishes two things. In the first place, it makes sure that the resin cures properly and adheres evenly. When applying fillings, this is critical to keep the filling in place in the mouth. For sealants, the curing light limits the risk of cracks and other problems with the sealant. With adhesives for implants and braces, the rapid, even cure is also designed to limit problems in the future.

The dental curing light also increases patient comfort by rapidly curing resins so that the patient is not forced to sit in discomfort while the resin sets. Since the mouth usually needs to be held open wide and may be dry for the procedure, patients usually want the procedure to end as quickly as possible so that they can close their mouths and remoisturize the dried oral membranes. Using a curing light gets patients in and out of the chair quickly so that the experience of irritation and pain is limited.

The selection of a curing light that fits your style of practicing remains one of the most important dental equipment purchases you will make. If you have an active restorative practice, it is a device that you use virtually every time you treat a patient. The right light can help you achieve success, while the converse is true – the wrong light can make your efforts more tedious and your results less consistent.

Curing lights allow us to initiate the polymerization reaction “on demand” for a vast array of materials. However, there is, perhaps, more misinformation and hype regarding this type of equipment compared to just about anything else we use on a daily basis. Most of these controversies center on how long you have to cure specific types of restorations as well as how deep you can cure specific types of materials.

Manufacturers continue to make outlandish claims of their curing capabilities, most of which fall into the “too good to be true” category. An example is the claim that a new light can accomplish a “5mm depth of cure in 3 seconds”. Please don’t be fooled by these ads – you absolutely, positively cannot cure a composite in three seconds. If you undercure a restoration, for example, you may not even be aware of the negative sequelae for years. Therefore, selecting a curing light and using it properly can greatly affect the performance and longevity of your restorations.
