| TYPES OF RPD | assresin appliance, resin with wire clasp, resin with castsed clasp |
| maxillary teeth will be lost before mandibular | INTERarch Difference |
| posterior teeth will be lost before anteriors | INTRAarch Difference |
| Remaining teeth usually | Mandibular anterior/Mandibular canine |
| anatomical result of tooth loss | broader mandible and constriction of maxilla |
| clinical significance of anatomic loss of teeth | hard time setting the pontics esp with remaining tooth because the jaw relationship is already class III |
| why does the jaw protrude? | compensate to cover/ close the mouth |
| Changes in facial features due to: | altered lip support, reduced facial height |
| Attached gingiva is replaced with | less keratinized oral mucosa |
| clinical significance of less keratinized oral mucosa | prone to trauma, lacerations, or to ulcers |
| physiologic effects of tooth loss | diminished masticatory effect, speech |
| serve the role of reducing food to a point that it is ready for swallowing. | Teeth or prostheses |
| ability to reduce food to a certain size in a given time frame | masticatory efficiency |
| index of food reduction | masticatory efficiency |
| TOOTH REPLACEMENT FROM THE PATIENT’S PERSPECTIVE | improves health/condition but not necessarily cure |
| improves health/condition but not necessarily cure | EXPECTED OUTCOMES |
| Those that might involve factors related to our control or manipulation as a dentist. | UNEXPECTED OUTCOMES |
| tissue damage, tissue abuse, design of dentures, materials that you use for the denture, or the design if you are fabricating RPD | UNEXPECTED OUTCOMES |
| Related to our control of manipulation:from faulty design not considering the impingement of tissues | Tissue damage |
| Related to our control of manipulation:Allergic reaction sample | Tissue damage |
| Related to our control of manipulation:rushing and randomly make a design leading to unexpected result (Correct design, correct px interview, correct manipulation and being prepared we can remedy the 3) | Prosthesis design |
| Those that we cannot control: | accidental trauma, parafunctional habits |
| A typical sequence is used to discuss tooth replacement options: | dental implant supported prosthesis, fixed prosthesis, rpd/cd |
| Purpose of Classification: | facilitate treatment decisions on the basis of treatment complexity |
| Complexity is determined from the four broad diagnostic categories | Location and extent of edentulous areas, Condition of the abutments, Occlusal characteristics and requirements, Residual ridge characteristics |
| CLASSIFICATION OF PARTIALLY EDENTULOUS ARCH (KENNEDY):Bilateral edentulous area located posterior to the remaining natural teeth | CLASS I |
| CLASSIFICATION OF PARTIALLY EDENTULOUS ARCH (KENNEDY):Also called bilateral distal extension cases | CLASS I |
| CLASSIFICATION OF PARTIALLY EDENTULOUS ARCH (KENNEDY):Unilateral edentulous area located posterior to the remaining natural teeth | CLASS II |
| CLASSIFICATION OF PARTIALLY EDENTULOUS ARCH (KENNEDY):Also called unilateral distal extension case | CLASS II |
| CLASSIFICATION OF PARTIALLY EDENTULOUS ARCH (KENNEDY):Unilateral edentulous area with remaining natural teeth both anterior and posterior to it | CLASS III |
| CLASSIFICATION OF PARTIALLY EDENTULOUS ARCH (KENNEDY):Single, but bilateral edentulous area located anterior to the remaining natural teeth | CLASS IV |
| Requirements of an Acceptable Method of Classification | It should permit immediate visualization of the type of partially edentulous arch that is being considered, It should permit immediate differentiation between tooth-supported and tooth-tissue-supported RPD, It should be universally acceptable |
| What then defines important differences between these prostheses? | technical outcomes, physical outcomes, esthetic outcomes, maintenance needs, initial and future costs, physiologic outcomes |
| The replacement prosthesis ideally should provide | function, level of comfort as equivalent as possible to normal dentition (gold standard). |
