For any FPD, diagnostic impression with putty is most useful and economical
It serves as diagnostic impression,
Diagnostic Casts made from it,
Mock preparations can be done from these casts
It can be used for making immediate temporaries
Same can be used to make final impression with Light Body
STEP THREE: GROSS TOOTH PREPARATION STEP BY STEP PREPARATION:
Do the occlusal/Incisal preparation first
This will reduce the tooth bulk a lot, gives more clarity of long axis of the tooth
Always do preparation by cutting motion
Do not follow wiping or swiping motion for preparation
Use new burs for preparation. I can’t explain the details of preparation but if you follow my unique technique of crown preparation, your preparation will be highly predictable , conservative and fast. It needs little Hands on Extracted teeth with 2 ,3 preparations only you will get to know how exactly this cutting motion works. Better join our Fixed Prosthetic Session or Clinical Dentistry Fellowship.
STEP FIVE: GINGIVAL RETRACTION:
Start gingival retraction with temporaries this will facilitate easy insertion of cord
Remove temporaries
Do final preparation and finishing
STEP SEVEN: BITE REGISTRATION
Take bite if necessary I will explain in detail About in my next Blog
STEP EIGHT: CEMENTATION OF TEMPORARIES:
Lute temporaries with temporary cement
Use noneuzenol cement for all ceramic or zirconia crowns
Use Euzenol cement for metal ceramic crowns
STEP TWO: SHADE MATCHING
Shade matching should be done before tooth preparation
You can’t get accurate shade from comparing adjacent tooth
STEP FOUR: TEMPORIZATION
Before going for final impression or gingival retraction
Prepare temporaries first
Lubricate the prepared teeth with petroleum jelly
Cut out excess material from the impression to have smooth re-seating
Prepare vent hole channels along with the cervical margins of the prepared teeth to the outer surface of the impression with a scraper /BP Blade
This will let out the excess material out of the impression without creating any undue pressure
Add temporary resin or acrylic mix into the diagnostic putty impression into the prepared teeth sockets and place it over the teeth
After initial setting when material starts polymerization(increase in the temperature of mix), take out the impression and temporaries
Remove excess material
Finish And polish it
Try these temporaries in patient’s mouth
Check seating and high points
STEP SIX: FINAL IMPRESSION
Now take final impression after few min of cord insertion
Take wash impression with light body, with or without cord, no need to add complete arch, just fill prepared teeth impression sockets and insert in patients mouth
Wait for 3 min and take out the impression Inspect for any voids, bubbles, irregularities
SUMMARY:
Here we used same putty for diagnostics, temporaries and for final impressions also
My sincere request is try using rubber base impressions for FPD’s and give immediate temporaries, may be metal ceramic or all ceramic
Alginates are used for diagnostics not for final impression
Cost may be higher by 200 Rs. But we are getting temporary along with that
We are giving immediate temporaries that’s a great relief for patients.
All together patients perception and your work standards will be improved with this.
Better join with us in the Fixed prosthetic session at Asian Dental Academy Hyderabad or NRDC Dental College Nanded, your complete perception towards Fixed prosthetics will be changed. We started Clinical Dentistry Fellowship where you will be given 10 cases of Endo, 10 cases of FPD’s and 10 cases of Restorative and Extractions. We also cover Laminates and Veneers in this.
BEST AND MOST ECONOMICAL STEPS FOR CROWN AND BRIDGE PROSTHESIS.
We are excited to share the news regarding the recent evolution of our academy. We have transformed Asian Dental Academy into Kosmo Dental Services. For any dental program-related queries you can visit our new website
