Preparing Complete Denture
1. Personal particulars2. Present complaints3. Dental History4. Medical History5. Extra-oral Examination6. Intra-oral Examination
(stomato-onkological examination) 7. Orthopantomogram8. Examination of the denture.
Diagnosis: Complete edentulousness
Treatment plan:upper and lower complete dentures
Prognosis
Primary impression:
It is an impression in which certain landmarks of the jaw are recorded.
Characteristics:
Stock tray
Static
Overextended
Dental materials for impression taking:
Plaster of Paris (history ) AlginateSilicon
Primary impression, outlineing the special tray.
The material of the special tray: -shellaque
-acrylat:-light curing,-self curing,-clear
Close fitting or spaced tray
Adjusting the special tray:
Border trimming materials:Green stick compound,impression wax, acrylic
Secondary impression taking techniques: -mucostatic -mucodinamic
Secondary impression materials: ZnO-eugenol paste
silikon
poliszulfid
Oroplastic impression material
Combinated technique:ZnO eugenol and oroplastic impression material
Working cast,Occlusal rims:
Boxing with impression wax
Jaw registrationPreparing upper and lower occlusal rims
Measures of wax rim:Highness at the front region:
Lower: 16-18 mmUpper: 18-22 mm
Highness at the molar region: till the middle of the tuberculum alveolare mandibulae
Width:Molar region: 6 mmFront region :3-4 mm
Not longer than the second molar
Jaw registration,Tooth shade selection
Determination of RVD, interocclusal space, OVD. Carving the orientation lines.
Semiadjustable and adjustable articulators construct occlusal balance in lateral, and protrusive movement of the mandible.
Casts are mounted on an articulatorSetting up the trial denture in the laboratory
Try in procedure
Flasking and packing acrylic resin
Fitting the complete denture, Short time recall, Long time recall
