The art and science of supplying artificial replacements.

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.

Branches of Prosthodontics

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

Used to cover cleft palate.

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

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

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

Denture that can be removed only by the dentist.

Restores all missing teeth.

Individuals with natural teeth present.

Individuala who lost natural teeth, partially or completely.

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

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

Spongy or Cancellous/Compact bone that provides better support.

Three Types of Mucosa

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

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

Alveolar Ridge Arch Shape

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

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

Slightly raised bone ridge along midline of hard palate.

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

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

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

Four Limiting Structures in Maxillary Tuberosity

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

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

Frenum Attachment Classification

Best or favorable prognosis,

Accommodates labial flanges of the denture

Accommodated buccal flanges of the area.

Affects the buccal flanges as the mandible moves forward.

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

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

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

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

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.

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

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

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

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

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

Near ridge crest in the premolar; feels burning sensation

Treated through surgical removal.

Band of fibrous tissue acts as a relieved area.

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

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

Attaches to the tongue anteriorly.

Two Lingual Border

Mylohyoid Muscle

Alveoligual Sulcus is divided into three:

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

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