11. RADIATIONS !

12. MATERIALS !
• IDEAL:-
• HIGH TEAR STRENGTH
• BIOCOMPATIBLE
• HIGH EDGE STRENGTH
• INERT CHEMICALLY AND SOLVENTS AND DISINFECTANTS
• LONG WORKING TIME
• REUSEABLE MOULD
• NON ALLERGIC RETAIN COLOUR
• TRANSLUCENT
• SOFTNESS AND ELONGATION

13. AVALABLE!
• ACRYLIC RESIN :-
• LITTLE MOVEMENT TAKES PLACE, COSMETIC , DURABLE, RIGID , MOLD NOT
REUSEABLE, INCREASE IN WT DUE TO WATER ABSORBTION.
• ACRYLIC POLYMER:-
• GOOD EDGE STRENGTH , TACKY STICKY AND COLLECTS DUST AND STAIN
• PVC:-
• HARD CLEAR RESIN, FLEXIBLE , ODOURLESS AND TASTELESS.DEGRADE IN UV
LIGHTS, EDGES TEAR EASILY, DISCOLORATION LOSS OF PLASTICIZER. ABSORBS
SEBACEOUS SECRETIONS.

14. • CHLORINATED POLYETHYLENE :-
• THERMOPLASTIC ELASTOMER.SUBSTITUTE FOR SILICONE FOR FABRICATION OF
EXTRAORAL MAXILLOFACIL PROSTHESIS , INEXPENSIVE.
• SILICONE:-
• MOST SUCCESSFUL
• GRADES
• 1 IMPLANT
• 2 MEDICAL
• 3 CLEAN
• 4 INDUSTRIAL
• POLYPHOSPHAZENES
• RESILIENT DENTURE LINING MATERIAL.
• FREEDOM OF MOVEMENTS OF DENTURE TOWARDS THE TISSUE

15. OBJECTIVES !
• ESTHETICS
• RESTORE FUNCTIONS
• SPEECH
• FEEDING
• PROTECT THE TISSUES
• RADIUM SHIELD
• CARRYING MEDICAMENTS AFTER SURGERY
• HEALING AFFECT
• PSHYCOLOGICAL THERAPY

16. PROSTHETICS V/S SURGICAL
REHABLITATION !
PROSTHETICS SURGICAL REHABILITATION
PLASTIC SURGERY CONTRAINDICATED INDICATED
RECURRENCE OF MALIGNANCY IS
INDICATED
NO RECURRENCE
DURING RADIOTHERAPY , RADIUM SHIELDS NILL
WHEN PLASTIC SURGERY REQUIRES
VARIOUS STEPS.
CLEFT PALATE NOT REPAIRABLE WUTH
SURGERY
IS NOT FOR TEMPORARY
EXPENSIVE
