Abstract

Improved methods and apparatus for the removal of plaque from interproximal areas of the dental anatomy and from periodontal pockets. An orbital vibratory motion about the longitudinal axis of the bristles is utilized to impart frictional forces from a multitude of bristles positioned within the interproximal area of two adjacent teeth and in the periodontal pockets of the gum. An advanced embodiment utilizes ultrasonically enhanced bristle tufts to transmit ultrasonic vibrations into the gingival fluids in the periodontal pockets, producing standing ultrasonic waves within the gingival fluids which augments and enhances the plaque removal capability of the orbitally vibrating nylon bristles.

Claims

1. A dental device for removing plaque from interproximal areas of the dental anatomy and from periodontal pockets, comprising:

A. a rigid elongated member having a handle portion and a bristle portion, said dental device having a central axis extending through said handle portion and said bristle portion;

B. means located within said handle portion for creating orbital vibration of said dental device about said central axis;

C. said bristle portion adapted for insertion into said interproximal areas between adjacent teeth and for insertion into said periodontal pockets having one or more bristle tufts, said bristle tufts comprising of bristles having diameters in a range between 0.03 mm and 0.40 mm, the longitudinal axis of said bristles oriented substantially in line with said central axis of said dental device;

D. said tuft of bristles activated by said orbital vibration imparting frictional forces to remove plaque through contact of said bristles with said plaque on surfaces of said teeth in said interproximal areas between said teeth and surfaces of said teeth and said gum in periodontal pockets.

2. A dental device according to claim 1 wherein said bristle portion is removably mounted into said handle portion.

3. A dental device for removing plaque from interproximal areas of the dental anatomy and from periodontal pockets, comprising:

A. a rigid elongated member having a handle portion and a bristle portion, said dental device having a central axis extending through said handle portion and said bristle portion;

B. first means located within said handle portion for creating orbital vibration of said dental device about said central axis;

C. second means located within said handle portion for creating ultrasonic vibrations within said bristle portion and generating standing ultrasonic waves within the gingival fluids filling said periodontal pockets;

D. said bristle portion adapted for insertion into said interproximal areas between adjacent teeth and for insertion into said periodontal pockets having one or more tuft of bristles, said tuft of bristles comprising of bristles having diameters in a range between 0.03 mm and 0.40 mm, the longitudinal axis of said bristles oriented substantially in line with said central axis of said dental device;

E. said tuft of bristles activated by said orbital vibration and said ultrasonic vibrations imparting frictional forces to remove plaque through contact of said bristles with said plaque on surfaces of said teeth in said interproximal areas between said teeth and said surfaces of said teeth and said surface of said gum in said periodontal pockets.

4. A dental device according to claim 3 wherein said bristle portion is removably mounted into said handle portion.

5. The method of facilitating the removal of plaque from the periodontal pockets of the dental anatomy defined by the external surfaces of the necks and roots of teeth and the internal surfaces of the gum separated from said necks and said roots of teeth comprising, inserting at least one bristle tuft into said periodontal pocket, inducing orbital vibration of said bristle tuft about the longitudinal axis of said bristle tuft of sufficiently high intensity to cause removal of said plaque from the said neck and root surfaces of teeth and said internal surfaces of gum by the friction generated between the cylindrical surfaces of said bristles and said plaque covering said neck and said root surfaces of teeth and said internal surface of gum by said orbital vibration of said bristle tufts.

6. The method as defined in claim 5 wherein the step of inducing said orbital vibrations of said tuft of bristles preceding the step of inserting said tuft of bristles into said periodontal pocket.

7. The method as defined in claim 6 wherein said tuft of bristles are also imparting ultrasonic wave vibrations to the gingival fluids between said neck and said root surfaces of teeth and said internal surface of gum.
