Modular dental chair equipment mounting system

Chair systems for the practice of dentistry and other similar procedures are known. A chair system typically includes a chair that is adjustable in height and is shaped to support the patient’s body, generally from the head to the lower legs. The chair can usually be reclined to position the patient, and particularly the patient’s mouth, for convenience to the dentist and other attending personnel.

According to one style of dental chair systems, various supplies used in dental procedures is positioned within reach of the attending personnel by movable support arms that are connected to the dental chair and dental instruments, usually near its base. Such equipment traditionally included tools and fluid systems for providing water, compressed air and vacuum. In the past, such support arms have been connected at various points, including either side of the chair, the front of the chair or the rear of the chair. In another style of chair system, such equipment arms are attached to nearby walls and are not attached to the chair itself.

Conventionally, both “two-handed” and “four-handed” dentistry styles are practiced. Two-handed dentistry refers to practices involving a single practitioner (e.g., dentist, assistant or hygienist), whereas four-handed dentistry refers to practices in which two individuals work together. In the past, available dental chair systems have been optimized for either two-handed or four-handed dentistry, and could not easily be adapted to switch between the two modes conveniently, as may be required in a busy practice.

In addition, most prior dental chair systems or ultrasonic scaler were optimized for either a right-handed practitioner or a left-handed practitioner and could not be easily switched between the two configurations. Thus, in modem practices where multiple dentists might each oversee a number of patients, scheduling each patient according to the dedicated equipment required by the supervising dentist can be quite cumbersome.

Also, in typical modem dentistry practice, much more equipment is made available to the dentist and to the patient than in the past. Such equipment may include information displays (such as one or more computer monitors), controls, lights, cuspidors, amalgam collection units, as well as traditional dentistry tools such as drills and compressed air, water and vacuum tools. Thus, providing such equipment in a safe and flexible handling arrangement that allows for its use in various modes presents additional challenges.

Sonic dental device and method

Presently, a majority of dental disease occurs on interproximal surface areas of teeth (i.e. the surface areas between teeth). A program of good dental hygiene which includes keeping the interproximal surface areas clean helps prevent dental disease from occurring in these areas.

Flossing is a well known and commonly used method of good dental hygiene by which interproximal surfaces of teeth are cleaned. Proper flossing cleans the interproximal surfaces both above and below the gum line thereby reducing the likelihood of dental disease on these surfaces. Although flossing is a valuable part of good dental hygiene, it is a tedious and time consuming task and, therefore, is seldom done properly.

There are various methods of cleaning teeth. Toothbrushes are used to clean teeth. However, toothbrushes cannot adequately clean interproximal surface areas because of the lack of access to these areas. Toothpicks are also used to clean teeth and also suffer from an inability to reach all interproximal surfaces adequately. Hydraulic dental irrigation systems may be used to clean these areas. However, it is well accepted that hydraulic irrigation alone is inadequate to remove the sticky plaque film which build up on teeth surfaces including interproximal surfaces.

If done properly, dental flossing is a highly effective method of improving dental hygiene with autoclave sterilizer and health of both teeth and periodontium which is between natural teeth and/or dental restorations in the mouth. Flossing action actually mechanically cleans bacteria laden plaque from tooth surfaces, particularly from interproximal tooth surfaces. Essentially, the floss wipes or scrubs off plaque and other undesirable debris from tooth surfaces. Although flossing is commonly known to be as important and as necessary as tooth brushing, it is widely neglected. Some of the most common complaints about flossing include that it is difficult to perform and is time consuming.

A variety of supplies have been introduced which attempt to make flossing easier. Most of these devices simply act as holders for the floss to reduce the manual dexterity required to floss. While such floss-holder devices like dental instruments may simplify some aspects of flossing, they generally have a fixed or limited range of motion and, therefore, have limited cleaning action and effectiveness. In addition, floss-holder devices are used manually, the cleaning energy conveyed to plaque covered tooth surfaces must be supplied by the user.
