What are the different gauges?

The Proportion Gauge The Crown Lengthening Gauge The Sounding Gauge

PROPORTION GAUGE

Proportion Gauge Measurement based instrument. Helps to measure the tooth width and length. Comprises of – T-bar tip (regular alignment) In-line tip ( crooked/crowded alignment) The instrument measurements have a predetermined ratio of about

78%. The clinician will be able to diagnose any tooth size and

proportion discrepancies that require correction to enhance patient aesthetics.

Incisal edge position must be determined before using this gauge

T-bar tip

T-bar tip The T-bar tip is designed to measure the width [horizontal

arm] and length [vertical arm] of a maxillary anterior tooth simultaneously.

The numbers are organized on the horizontal arm from inside to the outside - 5.5mm to 10.5mm.

Similarly on the vertical arm from bottom to the top - 7mm to 13.5mm.

All measurements start from the incisal guide. The most common width/length numbers for the lateral

(blue band), canine (yellow band), Central (red band) are 6.5/8.5, 7.5/9.5 and 8.5/11mm respectively.

T-bar in use

In-line Tip

In-line tip Indicated to be used on crowded teeth where

the use of T-bar tip may be difficult. The tip is designed to measure the width

[shorter arm] and length [longer arm] of the of the maxillary anterior teeth, independently.

The color bands on the shorter arm representing the width are aligned to the corresponding color bands on the long arm representing the length.

In-line in use

CROWN LENGTHENING GAUGE

Crown Lengthening Gauge Procedure based instrument. Used for crown lengthening procedure. Comprises of:

a) BLPG tip is used to achieve the proper clinical and biologic crown length during crown lengthening procedure.

b) Papilla tip is used to achieve an aesthetically ideal position of the interdental papilla during the crown lengthening procedure.

Incisal edge position must be determined before using this gauge

BioLogic Periogauge (BLPG) Tip

BioLogic Periogauge (BLPG) Tip The BLPG tip is designed to measure the midfacial length of

the new restored clinical crown and the length of the biologic crown [bone crest to the incisal edge], simultaneously.

The instrument is color-coded with a preset dentogingival complex measurement of 3 mm. This helps achieve the ideal 3mm difference between the clinical and the biologic crown length.

The color bands on the shorter arm representing clinical crown length portion are aligned to the corresponding color bands on the longer arm representing the biologic crown length of the instrument.

The short arm of the BLPG tip is of the same length and measurement as the long arm of the T-bar and In-line tip.

Papilla Tip

Papilla Tip The Papilla tip is designed to measure the interdental

length of the new restored clinical crown and the length of the biologic crown [bone crest to the interproximal incisal edge], simultaneously.

The tip is color coded with a preset length color ratio of 60% from the incisal edge to achieve an aesthetically ideal papilla position

The color bands on the shorter arm representing the interproximal papilla position are aligned to the corresponding color bands on the longer arm representing the interproximal biologic crown length

There is an interproximal incisal embrasure ‘guide’ to help position and orient the instrument during measurement.

SOUNDING GAUGE

Sounding Gauge

Sounding Gauge in use

• Provides quick, simple analysis of the bone crest location both mid-facially and interdentally.• Used in aesthetic and periodontal crown lengthening procedures to determine the bone level before reflecting the flap• Tip curvature allows easy manipulation and access.

Features Benefits

1. Provides precise measurements. Accurate results – Eliminates/reduces errors and chair side adjustment time.

2. Proportion Gauge can be used as a reference guide between clinicians and lab techs.

Improves the level of effective communication between the two to avoid errors and obtain high quality restorations.

3. Easy – simple – fast – less expensive. Saves time and money.

4. Easy to read color bands. Reduces chair side fatigue and stress.

5.Completely sterilizable. Reduces chances of cross-infection.
