Abstract
Abstract In an ultrasonic dental cleaning and scaling device, the ultrasonically energized scaling tip and the water nozzle are positioned adjacent to one another. The scaling tip is within a grooved shield and the water nozzle is positioned along the longitudinal groove of the shield. A wafer like stabilizing element is positioned and mounted around the shield. A tab portion of the stabilizer extends into the groove of the shield to fix the rotational position of the stabilizer. A small opening in the tab portion of the stabilizer accepts the water nozzle thereby positioning the water nozzle relative to the scaling tip and the shield.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
186 words
A stabilizer improvement for use with an ultrasonic dental device of the type having a water nozzle and a scaling tip positioned adjacent to one another and having a shield around the tip, the shield having a longitudinal groove within which the water tube extends, the stabilizer improvement comprising: a wafer-like body portion having a major first opening adapted to receive the shield and a minor second opening adapted to receive the shield and a minor second opening adapted to receive the water nozzle, said body portion including a tab extending into said first opening, said tab being dimensioned and positioned to extend into the groove of the shield when said stabilizer is mounted on the shield, whereby, when said stabilizer is mounted with said shield extending through said first opening, said water tube extending through said second opening and said tab extending into the groove of said shield, the water tube is positioned at a predetermined location to avoid contact with both the edges of the shield and the scaling tip as well as to be positioned adjacent to and directly over the scaling tip.
Claim 2
Dependent Claim
186 words
A stabilizer improvement for use with an ultrasonic dental device of the type having a water nozzle and a scaling tip positioned adjacent to one another and having a shield around the tip, the shield having a longitudinal groove within which the water tube extends, the stabilizer improvement comprising: a wafer-like body portion having a major first opening adapted to receive the shield and a minor second opening adapted to receive the shield and a minor second opening adapted to receive the water nozzle, said body portion including a tab extending into said first opening, said tab being dimensioned and positioned to extend into the groove of the shield when said stabilizer is mounted on the shield, whereby, when said stabilizer is mounted with said shield extending through said first opening, said water tube extending through said second opening and said tab extending into the groove of said shield, the water tube is positioned at a predetermined location to avoid contact with both the edges of the shield and the scaling tip as well as to be positioned adjacent to and directly over the scaling tip.
Claim 3
Dependent Claim
16 words
The stabilizer improvement of claim 1 wherein said second opening is positioned adjacent to said tab.
Claim 4
Dependent Claim
37 words
The stabilizer improvement of claim 1 wherein said first opening is dimensioned to provide a slip fit relationship with the shield and said second opening is dimensioned to provide a slip fit relationship with the water tube.
Claim 5
Dependent Claim
15 words
The stabilizer improvement of claim 3 wherein said second opening is adjacent to said tab.
