About This Presentation

Description : Check out this medical PowerPoint presentation titled "Introduction to Prosthodontics” by Rola M. Shadid, BDS, MSc.

This medical PowerPoint presentation is about prosthodontics, a branch of dentistry that focuses on the restoration and replacement of missing or damaged teeth, as well as the overall rehabilitation of oral function and aesthetics. Prosthodontists are specialists who receive additional training beyond general dentistry to become experts in the diagnosis, treatment planning, and delivery of complex restorative and prosthetic dental care.

The goal of prosthodontics is to restore optimal oral function, comfort, and esthetics, while also addressing the patients unique needs and desires. Prosthodontists use a variety of dental materials and techniques to design and create custom-made restorations, such as crowns, bridges, dentures, and dental implants. They also work closely with other dental specialists, such as periodontists and orthodontists, to provide comprehensive care for patients with complex dental problems.

Prosthodontics plays a critical role in improving the quality of life for patients who have lost one or more teeth, suffered from dental trauma, or have congenital anomalies that affect their oral health. By restoring their ability to eat, speak, and smile with confidence, prosthodontists can help patients regain their self-esteem and improve their overall well-being.

Slide 1-

Introduction to Prosthodontics Rola M. Shadid, BDS, MSc,
Slide 2-

History of false teeth Replacements of lost teeth have been produced for thousands of years 1st dentures were 700 BC from ivory & bone Silver, gold, mother of pearl In 1774, dentures made from porcelain The real breakthrough came when vulcanized rubber was discovered
Slide 3-

History of false teeth The discovery of acrylic resin is the next major revolution in prosthodontics Another important milestone in tooth replacement was the introduction of implants.
Slide 4-

Definitions Prosthetics: Replacements for missing parts of the human body. Prosthodontics: The branch of dentistry pertaining to the restoration and maintenance of oral function, comfort, appearance, and health of the patient Prosthesis: An artificial replacement of absent part of human body
Slide 5-

Definitions Dentulous: An individual who has his/her natural teeth present. Edentulous: The individual who has lost his/her natural teeth. Depending on the number of teeth missing they may be partially or completely edentulous.
Slide 6-

Branches of Prosthodontics Fixed prosthodontics Removable prosthodontics a) complete denture prosthodontics b) partial denture prosthodontics Implant prosthodontics Maxillofacial prosthetics
Slide 7-

Types of Prostheses Denture: A prosthesis which replaces the one or more teeth and related structures in the mouth. Partial, complete, fixed or removable. Partial denture: A dental prosthesis which restores part not all of the dentition. Fixed partial denture: luted or securely retained to natural teeth, roots, or dental implants. The patient cant remove from the mouth.
Slide 8-

Types of Prostheses Removable partial denture: Any prosthesis that replaces the teeth in a partially dentate arch. The patient can remove it from the mouth. Complete denture: A removable dental prosthesis that replaces the entire dentition and associated structures of the maxilla and mandible.
Slide 9-

Reasons for tooth loss Traumatic injuries Caries Periodontal diseases Cysts, malignancies and tumors Radiation therapy for tumors Grossly malaligned teeth Iatrogenic extraction Congenitally missing teeth Failure to erupt (impacted teeth)
Slide 10-

Sequelae of tooth loss Resorption: The socket gradually remodels until it assumes the shape of the rounded edentulous ridge. Tilting Drifting Occlusal disharmony leads to discomfort, pain, or damage to temporomandibular joints.

Treatment objectives of CD Patient education Restoration of esthetics Improvement of mastication Improvement of speech Preservation of remaining oral structures
Slide 21-

Treatment objectives of CD Maintenance of the health and comfort of the mouth Maintenance of the health of the TMJ General physical and psychological well being of the patient.
Slide 22-

The residual alveolar ridges Following loss or extraction of teeth: The empty socket fills with clot and gradually replaced with new bone The bone around the socket reorganizes The mucoperiosteum gradually heals & covers the healing socket The remodelling process results in a rounded ridge like structure known as the residual alveolar ridge ( RAR)
Slide 23-

The RAR plays a very important role in the construction of the CD
Slide 24-

Six orders of residual ridge form Order I Preextraction Order II Postextraction Order III High, well rounded Order IV Knife edge Order V Low, well rounded Order VI Depressed
Slide 25-

Six orders of residual ridge form
Slide 26-

Rate of resorption Most rapid in the first 1 year after extraction and can be as high as 4.5 mm / year. After healing of residual ridge, annual rate of reduction in height is about 0.1-0.2 mm in mandible Annual rate of reduction in height is about 4X greater in mandible than in maxilla.
Slide 27-

Pattern of resorption Maxilla The resorption is upwards and inwards (smaller) Mandible The resorption is downward and outward (wider)
Slide 28-

Masticatory loads Significantly lower than that produced by natural teeth Natural teeth can produce forces up to 175 pounds but usually 40 to 50 pounds Denture wearers: the average force was in the region of 22-24 pounds in the molar-bicuspid region
Slide 29-

Masticatory loads CD wearers are able to generate forces that are only 10-15% of those with natural teeth
