None to declare except that patent filing is supported by King George’s Medical University, Lucknow.

3. FIELD OF INVENTION
The present invention relates to dental instruments and devices
Made of plastic and glass parts which allows the mixing of adhesive and non-adhesive dental materials on the same slab
Back side is flat surface which is used to mix large amount of materials

4. DESCRIPTION OF THE RELATED ARt
A number of products are available in the market in the form of dental mixing slab made up of double thick glass for mixing of ionomer cement & other preparations or solutions

5. Dental mixing pads and disposable mixing pads - limited in numbers and disposable.
Always a chance of cross contamination when material used directly from the pack.
Mixing of various kinds of materials like adhesive and non-adhesive materials on the same slab is also not possible.

6. OBJECTIVES OF THE INVENTION
Use of adhesive and non-adhesive dental materials on the same slab.
Prevents wastage of mixing materials.
Prevents the contamination
Useful to Prosthodontics and Orthodontics
Maintains sterilization and save time

8. Drain: Slanting coating drains and have partial cylindrical tunnel like configuration
Well: Smoothly curved configuration similar to partial sphere

9. SUGGESTED CLAIMS for plastic mixing slab
Used for the mixing of adhesive dental restorative and endodontic materials- flowable/liquid adhesive dental materials like etchant, bonding agent of composite restoration.
Slanting drain is used for easily coating of mixed adhesive sealer (liquid state) on lantulo spiral or file and then transfer in the root canals without bending of the instruments.

10. SUGGESTED CLAIMS for Glass mixing slab
Slanting drain is used for transferring the intra-canal medicaments and mixed sealers in root canal with the help of file or lantulospiral.
Well dispenser is used for the non-adhesive liquids like varnish, eugenol, pulp devitalizing agents and other restorative materials.

11. Suggested claims continue…
Flat plastic mixing part: mixing of the adhesive restorative materials like glass ionomer cement, zinc polycarboxylate cement, resin cement, endodontic sealer like AH sealer, mixing of two shades of composites restorative material
Flat glass mixing part: mixing of non-adhesive dental cements like zinc phosphate, zinc oxide eugenol, calcium hydroxide and sealers

12. Suggested claims continue…
In Prosthodontics: mixing zinc oxide eugenol impression paste, light body elastomeric impression paste, self cure acrylic resin and dispensing cold mold seal, pressure indication paste etc.
In Orthodontics: orthodontic bracket is easily pre-coated with adhesive in the plastic well dispenser.

13. SUMMARY OF THE INVENTION
The present invention increase the multiple use of dental materials on one slab therefore reduce the time, effort and ultimately treatment cost to patients.
