The art and science of supplying artificial replacements.

Prosthetics

The 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.

Prosthodontics

Branches of Prosthodontics

Fixed Prosthodontics, Removable Prosthodontics, Complete/ Partial Prosthodontics

Concern with the replacement of missing teeth and/or associated structures by restorations attached to dental implant.

Implant Prosthodontics

Used to cover cleft palate.

Obturators

Concerns with the restoration and replacement of stomatognathic and associated facial structures with prosthesis that may or may not be elective base.

Maxillofacial Prosthesis

A prosthesis which replaces one or more teeth and related structures in the mouth.

Denture

Denture that can be removed by either the patient or dentist.

Partial Denture

Denture that can be removed only by the dentist.

Fixed RPD

Restores all missing teeth.

Complete Denture

Individuals with natural teeth present.

Dentulous

Individuala who lost natural teeth, partially or completely.

Edentulous

T or F. RPD should come first before fixed bridge.

True

Cushion between hard denture surface and the bone, varies in thickness, loosely attached or firmly attached.

Soft Tissue

Spongy or Cancellous/Compact bone that provides better support.

Alveolar Bone

Three Types of Mucosa

Masticatory Mucosa, Lining Mucosa, Specialized Mucosa

T or F. Denture bearing area in mandibular I'd greater than in mandibular since it is firmly attached and keratinized.

False

Function as primary stress bearing area that can withstand forces if mastication in maxillary.

Residual Alveolar Ridge

Alveolar Ridge Arch Shape

Class 1: Square Class 2: Tapered Class 3: Ovoid

T or F. Types based on the shape (cross section) 1. U-Shaped - Good Prognosis 2. V-Shaped/Tapered - Favorable 3. Knife Edge - Poor Prognosis usually seen in mandible 4. Flat - Poor Prognosis 5. Inverted - Poor Prognosis 6. Undercut - Potential Difficulties

True

Function as secondary stress bearing area in maxillary anterior part of hard palate.

Rugae Area

Slightly raised bone ridge along midline of hard palate.

Median Palatine Raphe

Mostly used as guide of patient's midline; located behind central incisiors.

Incisive Papilla

Function to relieved when prominent preventing soreness; located buccal to first molar region.

Zygomatic Process

Function as secondary stress bearing area in maxillary located in posterior most part of maxillary edentulous ridge.

Maxillary Tuberosity

Four Limiting Structures in Maxillary Tuberosity

Labial Frenum, Buccal Frenum, Labial Vestibule, Buccal Vestibule

Function as relieved area located in the fold of mucous membrane at the median line.

Labial Frenum

May be single fold, double fold, or fam shape located in fold of membrane found on buccal side.

Buccal Frenum

Frenum Attachment Classification

Class 1: Sulcal or Low Attachment, Class 2: Attached midway between the sulcus and crest of the ridge, Class 3: Crystal or Near Crestal Attachment

Best or favorable prognosis,

Sulcal or Low Attachment

Accommodates labial flanges of the denture

Labial Vestibule

Accommodated buccal flanges of the area.

Buccal Vestibule

Affects the buccal flanges as the mandible moves forward.

Coronoid Process

Strongest masticatory muscle; reduces distobuccal space under heavy biting pressure that can destabilize denture.

Masseter Muscle

Marks posterior limit of the denture located distal to maxillary tuberosity.

Pterygomaxillary Hamular Notch

Can dislodge tissue or injury extends from hamulus to the distolingual corner of the retromolar pad.

Pterygomandibular Raphe

Guide for posterior border of denture; t wo small indentation found on the posterior part the palate of the midline; 2mm arbitrarilly;

Palatine Fovea

Junction of the hard and soft palates on which pressure within physiologic limits can be applied by a removable complete denture to aid in its retention.

Posterior Palatal Seal

T or F. Posterior Palatal Seal Class 1: Slopes almost horizontal Class 2: 45° from hard palate Class 3: 70° slope from hard palate

True

Covered with keratinized tissue but bone is cancellous; prone to bone resorption.

Crest of Alveolar Ridge

Function as secondary stress bearing area in mandibular; thin plate of the cortical bone.

Slopes of Residual Ridge

Function as primary stress bearing area for its right angle to vertical force covered with dense smooth cortical bone in mandibular.

Buccal Shelf Area

Bony ridge on the lingual side; determines the height of lingula flange.

Mylohyoid Ridge

Near ridge crest in the premolar; feels burning sensation

Mental Foramen

Treated through surgical removal.

Torus Mandibularis

Band of fibrous tissue acts as a relieved area.

Labial Frenum on Buccal Frenum

Does not govern the extension of buccal flange but by the mucobuccal flange by the mucobuccal fold.

External Oblique Ridge

Triangular glandular pad that forms part of the valve seal area of the mandibular; 2/3 limit of posterior.

Retromolar Pad

Attaches to the tongue anteriorly.

Lingual Frenum

Two Lingual Border

Retromylohyoid Curtain, Alveoligual Sulcus

Mylohyoid Muscle

Post: 1cm distal end of mylohyoid ridge, Ant: up to midline, Med:mylohyoid muscle pf both sides

Alveoligual Sulcus is divided into three:

Ant: Premylohyoid Fossa, Mid: Mylohyoid, Post: Retromylohyoid Fossa

Hard projection on the lingual side of the mandible in the midline.

Genial Tubercle

Limits the height of the lingual flange; rest on the anterior region of mylohyoid

Sublingual Gland Region
