1. Unit 1- Introduction to Complete Denture

2. What is definition of dentistry ? Dentistry, the profession concerned with the prevention and treatment of oral disease, including diseases of the teeth and supporting structures and diseases of the soft tissues of the mouth.

3. Branches or specialty's in dentistry Orthodontics Pediatric dentistry Periodontics Prosthodontics Oral and maxillofacial surgery Oral and maxillofacial pathology Endodontics Public health dentistry

4. Prosthodontics Prosthodontics  is concerned with the restoration and maintenance of oral function, comfort, appearance, and health by the replacement of missing teeth and contiguous tissues with artificial substitutes, or prostheses .

5. Prostheses or Artificial substitutes IT IS THE REPLACMENT OF AN ABSENT PART OF HUMAN BODY BY AN ARTIFICIAL ONE.

6. Branches of prosthodontics Fixed Removable Maxillofacial Fixed partial denture Complete denture Removable partial denture

7. Oral cavity Full Dentition Edentulous Complete Denture Removable Partial Denture Fixed Partial Denture Partially Edentulous

8. Fully Dentulous or Dentulous :- Having all the teeth in the oral cavity Partially Edentulous :- Some teeth are missing Edentulous: - Missing off all the teeth Treatment options for missing teeth Edentulous condition:- complete denture- the replacement of the natural teeth in the arch and their associated parts by artificial substitutes partially edentulous :- i . fixed partial denture – a partial denture that is luted or otherwise securely retained to natural teeth, tooth roots and/or dental implant abutments that furnish the primary support to the prosthesis ii. Removable partial denture - PD that can be removed from the mouth and replaced at will by the patient

9. Complete Denture The replacement of the natural teeth in the arch and their associated parts by artificial substitutes

10. Objective of complete denture prosthesis Restoration of esthetics Restoration of speech Restoration of mastication (chewing) Preservation of the remaining tissue health Patient satisfaction and comfort

11. Function of Complete Denture Mastication:- Chew food for swallowing and digestion Speech(Phonetics) :- The teeth either natural or artificial assist the tongue and lips to form some of the sound of speech. Appearance(aesthetic):- Is influence by the shape of jaws together with the position and occlusal relation ship of the teeth Health of the alveolar bone and the temporomandibular joins (TMJ)

12. Indications for Complete Denture

13. Unit 2 - Components of Complete Denture

14. Parts of Complete Denture (CD) 1. Denture base – Which cover the edentulous tissue area and carries the artificial teeth 2. Teeth – which are attached to the denture base for the purpose of chewing, esthetics, phonetics.. etc Denture base Teeth

15. The CD has 3 surface Polished surface the outer surface of the denture and in contact to the muscle of cheek and tongue Polished surface

16. 2. Fitting surface The inner surface of the denture that contact to the oral mucosa

17. Occlusal surface ;- a surface of posterior teeth or occlusion rim that is intended to make contact with opposing occlusal surface occlusal surface

18. CD Types Conventional Immediate – a removable complete denture fabricated for replacement immediately following the removal of natural teeth Overdenture – a removable denture that covers and rests on one or more remaining natural teeth, roots and/or dental implants. Single Denture – it is a denture either maxillary or mandibular that is opposed either natural teeth or removable partial denture or fixed partial or old denture

19. Steps in complete denture fabrication Clinical steps ( done by Dentist ) Diagnostic impression or primary impression Secondary impression Jaw relations Try in Denture insertion Laboratory steps ( done by Dental Technician) Primary cast 1. Custom tray or special tray 2. Secondary cast or master cast 2. Denture base and occlusal rims 3. Articulation 3. Teeth setting 4. Flasking , dewaxing , acrylisation , curing, finishing and polishing

20. 1. Clinical step – Primary Impression or Diagnostic Impression Made with impression compound(thermoplastic resin) or alginate(irreversible hydrocolloid)

21. 1. Laboratory step:- pouring the primary impression and fabrication of primary cast Primary cast is fabricated by using the plaster of Paris ( gypsum products – type 2)

22. 1. Laboratory step- fabrication of custom tray or special tray spacer Custom tray fabricated by using self cure acrylic resin

23. 2. Clinical step- Secondary Impression Made with elastomeric impression materials

24. 2. Laboratory step:- Pouring the secondary impression and fabrication of master cast Master cast(definitive cast) fabricated by using the Dental stone ( Gypsum product type 3)

25. 2. Laboratory step:- fabrication of denture base and occlusal rims Denture base or record base if fabricated by self cure acrylic resin or heat cure acrylic resin or metal base Occlusal rims are fabricated b y using the dental wax Metal denture base

26. 3. Clinical step- jaw relations

27. 3. Articulation and teeth setting Artificial teeth are fabricated by using the acrylic resin

28. 4. Clinical step- try in

29. 4 . Laboratory step- flasking , dewaxing, acrylization and curing

30. 4. Laboratory step- finishing and polishing the denture

31. 5. Clinical step- Denture insertion
