Intro to RPD

Prosthodontics is a branch of dental art and science that deals .with the replacement

of missing teeth and oral tissues to restore and maintain -__________

-Oral form

-Function

-Appearance

-Health.

Dental specialty pertaining to the diagnosis, treatment planning, rehabilitation and maintenance of the oral function, comfort, appearance and health of patients

with clinical conditions associated with missing or deficient teeth and/or oral and maxillofacial tissues using biocompatible substitutes.

Prosthodontics

Branches of Prosthodontics

1. Fixed

2. Removable

   1. Partial

   2. Complete

3. Maxillofacial

Artificial replacement for a missing body part

Prosthesis

Artificial replacement of one or more teeth and/or associated structures

Dental prosthesis

Any tooth or dental implant that supports a dental prosthesis

Abutment

Portion of the prosthesis that attaches the prosthesis to the abutment

Retainer

Lie on the surface of the clinical crown

Extracoronal Retainers

Contained entirely within the contours of a clinical crown

Intracoronal Retainers

A partial denture that receives support from the natural teeth at each end of the edentulous space/s

Tooth supported/ Tooth bounded FPD

The denture base that extends anteriorly/posteriorly and is supported by teeth at one end and tissue on the other end

Tooth Tissue Supported RPD/ Distal Extension

provisional prosthesis intended to improve esthetics and function until a more definitive form of treatment can be rendered

Interim removable partial denture

Indications for Interim removable partial denture

●Insufficient time for a complete mouth rehabilitation

● poor health of the patient

● premature loss of teeth in young patient – due to trauma

● recent extraction cases

When loss of additional teeth is inevitable, but immediate extraction is not advisable or desirable It can become an interim denture when all teeth have been removed from the dental arches.

Transitional removable partial denture

May be used as a carrier for treatment material, as a protective covering for a surgical site, or as a matrix for soft tissue healing used when the soft tissue have been abused by ill-fitting prosthetic devices.

Treatment denture

• Vehicle for tissue conditioner

Treatment Denture

• Erythema or hyperkeratinization, marginal gingivitis, papillary hyperplasia or papillomatosis

Treatment denture

Indications of treatment denture:

• Establishment of new occlusal relationship

• Restoration of new vertical dimension

• Conditioning abused tissues prior to construction of a definitive prosthesis

It is the most posterior relation of mandible to the maxilla at the established vertical dimension from which lateral movements could be made

Centric Relation

The maximum intercuspation between the upper and lower teeth Maximum intercuspal position maxillomandibular relationship determined by tooth-to-tooth relationships

Centric Occlusion

Resistance to displacement away from the teeth and soft

tissues of the dental arch

Resistance

Resistance to displacement toward the teeth and soft tissues of the dental arch

Support

Resistance to displacement in a mediolateral or

anteroposterior direction

Stability

General Principles for RPD

• When more than _ _______ teeth or _ ________ teeth are

missing

2 posterior

4 anterior

General Principles for RPD

• If the _____ and 2 of its adjacent teeth are missing

Canine

General Principles for RPD

• When there is no _____ abutment tooth

Distal Abutment

General Principles for RPD

Presence of multiple _______ ________

Edentulous spaces

General Principles for RPD

- If the teeth adjacent to edentulous spaces are _____, they

cannot be used as an abutment for a fixed prosthesis

tipped

General Principles for RPD

If periodontally weakened teeth are present near the

________ ______

Edentulous spaces

General Principles for RPD

• Teeth with ___ clinical crowns

Short Clinical Crowns

General Principles for RPD

Insufficient number of _______

Abutments

General Principles for RPD

Severe loss of _____on the edentulous space

Severe loss of tissue

General Principles for RPD

___patients (age factor)

Old patients

Objectives of RPD

- Preserve remaining teeth and supporting structures

- Restore esthetics and phonetics

- Restore and/or improve mastication,

- Restore health, comfort and quality of life

- To carry out these procedure in a manner that would not cause harm and

discomfort to the patient.

Consequences of Tooth Loss

- Undermined _________appearance

- Changes in _________

- Self-consciousness, dissatisfaction with appearance and

loss of _______

- ____,______,_____ problems

- Social ________ and isolation

- ______ ______ for costs of possible treatment options

1. Cosmetic

2. facial features, loss of bone and gum tissue,

   trouble eating and speaking, poor nutrition

3. Confidence

4.Pain, distress and relaxation

5. embarrassment

6. Financial burden

Consequences of Tooth Loss

- Loss of masticatory ________

- Tipping and ________ of teeth

- _______of teeth

- Loss of ________dimension

- ___ dysfunction

- Traumatic ______

1. Efficiency

2. migration

3. Extrusion

4. Vertical

5. TMJ

6.gingivitis

Indications for RPD

- Long-span edentulous area

- Excessive bone loss within the residual ridge

- Restoration of Facial Contours

- Physical or emotional problems exhibited by patient

- Immediate need to replace extracted teeth

- Esthetics of primary concern

- Patient desires

• to avoid operative procedures on sound, healthy teeth

• to avoid the placement of one or more implants

• for economic reasons

- Young patients (less than 17)

- Shortened life expectancy

- Unblemished Abutment

Indications for RPD

Patient with Diabetes

- Diabetic patient, even if controlled by means of diet and drugs may

experience difficulty in ____any oral prosthesis with _____.

wearing any oral prosthesis with comfort.

Indications for RPD

Patient with Diabetes

- _________ is more preferred than complete

denture, since partial denture inflict less trauma on the mucosa.

Lesser abrasion can be seen.

- Removable partial denture is more preferred than complete

denture in diabetic patients

Indications for RPD

Patient with Diabetes

-____ _____ transmit majority of the load to the underlying

ridge, faster_________ is expected especially to this type of

patient.

• Complete denture

• faster bone resorption

Indications for RPD

- Alteration of Vertical Dimension

-Obliteration of Cleft Palate

- Unfavorable maxillomandibular

relationships
