A. Definition of Terms:

Definition: 

Definition Prosthetics The art and science of supplying artificial replacements. Replacements for missing parts of the human body Prosthesis An artificial replacement of an absent part of human body A therapeutic device to improve or alter function A device used to aid I accomplishing a desired surgical result.

Prosthodontics: 

Prosthodontics Branch of dentistry pertaining to the restoration and maintenance of oral function comfort, appearance and health of the patients by the restoration of natural teeth and/or the replacement of missing teeth and contiguous oral and maxillofacial tissues with artificial replacement

Branches of Prosthodontics : 

Branches of Prosthodontics Fixed Prostodontics Removable Prosthodontics Partial Prosthodontics Complete Denture Prosthodontics Implant Prosthodontics Maxillofacial Prosthetics

Fixed Prosthodontics : 

Fixed Prosthodontics The branch of prosthodontics concerned with the replacement and/ or restoration of teeth by artificial substitutes that are not readily removed from the mouth Removable Prosthodontics The branch of prosthodontics concerned with the replacement of teeth and contiguous structures for edentulous or partially edentulous patients by artificial substitutes that are readily removable from the mouth.

Implant Prosthodontics : 

Implant Prosthodontics The phase of prosthodontics concerning the replacement of missing teeth and/ or associated structures by restorations that are attached to dental implants. Maxillofacial Prosthetics The branch of prosthodontics pertaining to the restoration and/ or replacement of the stomatognathic and associated structures with prostheses that may or may not be removed on a regular or elective basis.

Types of Prostheses : 

Types of Prostheses Denture. A prosthesis which replaces the one or more teeth and related structures in the mouth. May be partial or complete, fixed or removable. Partial Denture. A dental prosthesis which restores part but not all of the dentition. May be fixed or removable. 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 for the prosthesis. Removable partial denture – Any prosthesis that replaces the teeth in partially dentate arch. It can be removed from the mouth and replaced it will. Complete Denture. A removable denture prosthesis that replaces the entire dentition and associated structures of the maxillae or mandible

PowerPoint Presentation: 

Prosthesis Artificial replacement of an absent part of a human body. A device used to aid in accomplishing a desired surgical result for functional and cosmetic purposes. Dental Prosthesis Artificial replacement of missing dental and oral structure used for function, cosmetics, and phonetics.

B. Aims of Complete Denture Restoration

PowerPoint Presentation: 

Elimination of oral disease Replacement of local or missing teeth to restore function, esthetics and phonetics. Maintenance of the health of teeth and oral tissues and their proper relationship.

C. Indication and Contraindications of Complete Denture: 

C. Indication and Contraindications of Complete Denture

PowerPoint Presentation: 

Indication: Complete Edentulous Maxillary and Mandibular Ridges Complete Edentulous Maxillary or Mandibular ridges Patients whose prognosis of remaining teeth is poor

PowerPoint Presentation: 

Contraindication: Medically Compromised patient Medically Handicap patient Infected socket after tooth extraction Necrosis of bone (diabetes) Abscesses, ulcers, and cyst Embedded and Impacted Roots and teeth Tumors Any Inflammatory condition that would incorporate by the irritation of the complete denture.

UPPER LANDMARKS

SUPPORTING SRUCTURES OF MAXILLARY: 

SUPPORTING SRUCTURES OF MAXILLARY Residual Ridge Primary stress bearing area Covered with a layer of fibrous C.T that is firmly attached. Rugae Secondary stress bearing area If tissue distorts while making impression, it can rebound & unseat the denture.

PowerPoint Presentation: 

Residual Ridge

PowerPoint Presentation: 

Hard palate It forms the secondary retentive area. Maxillary tuberosity Hypermobile tuberosity may interfere with the stability of the denture. Zygomatic process Must be relieved when prominent to prevent soreness.

LIMITING STRUCTURES OF MAXILLARY: 

LIMITING STRUCTURES OF MAXILLARY Labial vestibule Provides valve seal It affects the appearance of the px. Buccal vestibule Contributes to the peripheral seal Accommodate the buccal flange of the denture.

PowerPoint Presentation: 

Labial vestibule Buccal Vestibule

PowerPoint Presentation: 

Hamular notch Marks the posterior limit of the denture. Additional pressure can be placed in the mouth. Fovea Palatine Serves as an ideal guide for the location of posterior border of the denture.

PowerPoint Presentation: 

Hamular Notch

RELIEF STRUCTURES OF MAXILLARY: 

RELIEF STRUCTURES OF MAXILLARY Incisive papilla To prevent pressure on the emerging nasopalatine nerves Median palatine raphe pressure can lead to soreness & severe pain. If not adequately relieved it can act as a fulcrum print w/c leads to rocking of dentures.

PowerPoint Presentation: 

Incisive Papilla Median palatine raphe

PowerPoint Presentation: 

Labial Frenum failure to relieve frenum can lead to irritation. Recorded as a narrow notch in the impression called “ labial notch”.

PowerPoint Presentation: 

Buccal frenum Recorded in the impression as “buccal notch”.

LOWER LANDMARKS

SUPPORTING STRUCTURE OF MANDIBULAR: 

SUPPORTING STRUCTURE OF MANDIBULAR Residual ridge Secondary stress bearing & relief area. Buccal shelf Primary stress bearing area. Mylohyoid ridge Determines the height of lingual flange Often hidden by soft tissues & can be found by palpation.

LIMITING STRUCTURES OF MANDIBULAR: 

LIMITING STRUCTURES OF MANDIBULAR Labial vestibule Forms part of valve seal area & accommodates labial flange of the denture. Buccal vestibule Forms valve seal & accommodates buccal flange of md. Denture. Retromolar Pad Forms part of a valve seal.

PowerPoint Presentation: 

Retro Molar Pad Labial Vestibule

PowerPoint Presentation: 

Retromylohyoid curtain Accommodates distolingual part of a denture. It forms part of peripheral valve seal. Alveololingual Sulcus Allows room for action of mylohyoid muscle & allows the tongue to rest on flange aiding retention.
