1 Laboratory stages of manufacture of complete dentures
Laboratory stages of manufacture of complete dentures. Peculiarities of choice of materials for prostheses in patients Gerontological profile.

2 Complete Denture

3 Complete denture prosthodontics:
involves an artificial replacement of the lost natural dentition and associated structures of the maxilla and mandible for patient who has lost all their remaining natural teeth. Complete denture A removable dental prosthesis that replaces the entire dentition and associated structures of the maxilla or mandible.

4 Diagnosis and Treatment Plan

5 Complete dentures have three surfaces:
1- The fitting surface. 2- The occlusal surface. 3- The polished surface.

6 Tissue Condition Improve Tissue Health

7 Clinical and laboratory steps of complete denture construction
1. Examination of the mouth. 2. Preliminary impression making. Pouring of impression to obtain the Construction of special (custom) trays 3. Final impression. Boxing and pouring of the final Construction of recording bases 4. Recording jaw relationships and selection of artificial teeth. Mounting of the models with occlusal rims on articulator. setting-up of teeth and waxing-up. 5. Try-in of the waxed-up denture. Processing of the dentures (flasking, wax elimination, packing, curing, deflasking & polishing 6. Insertion of the finished denture. 7. Post-insertion care.

8 Tissue Condition Resilient Liner

9 Repair Denture if Necessary

10 Preliminary Impressions

11 Pour Diagnostic Casts

12 Make Custom Trays More Accurate Impressions

13 Border Mold Accurate Registration of Peripheries for Retention

14 Remove Tray Spacer and Load Impression Material

15 Make Final Impression

16 Box Impression Stronger cast with peripheries for Processing

17 Pour Master Casts

18 Record Bases and Occlusion Rims For Making Jaw Relationship Records

19 Facebow Record Relates Maxilla to Transverse Hinge Axis

20 Mount Maxillary Cast Same Relationship to Transverse Hinge Axis

21 Determine Occlusal Vertical Dimension Facial Height/Separation of Dentures

22 Centric Relation Registration Ant/Post & Mediolateral Relationships

23 Mount Mandibular Cast on Articulator

24 Set Anterior and Posterior Teeth in Wax Ability to Visualize and Change Appearance

25 Finalize Waxup

26 Remove Denture from Articulator Flask for Processing

27 Flask Waxup

28 Boil Out Wax and Remove Record Bases Teeth Trapped in Stone

29 Pack Acrylic Resin Hydraulic Pressure or Injection

30 Remount and Adjust for Processing Errors

31 Fabricate Remount Index

32 Remove From Cast Finish and Polish

33 Remount & Adjust Occlusion

34 Variations Single Dentures

35 Delivery to the patients

36 Function of complete denture:
1- Mastication: chew food for swallowing and digestion. 2- Speech (phonetics): the teeth either natural or artificial assist the tongue and lips to form some of the sounds of speech. 3- Appearance (aesthetic): is influence by the shape of jaws together with the position and occlusal relation ship of the teeth. 4- Health of the alveolar bone and the tempro mandibular joints (T.M.J).
