Fixed prosthodontics is a field of restorative dentistry that focuses on repairing or replacing damaged or missing teeth using dental prostheses that are permanently attached to natural teeth or dental implants. Unlike removable appliances such as dentures, fixed prosthetic restorations are designed to remain securely in place and can only be removed by a dental professional. Common fixed prosthodontic treatments include dental crowns, fixed bridges, implant-supported crowns, implant-supported bridges, and certain types of veneers. These restorations are fabricated in dental laboratories or with digital manufacturing technologies to match the shape, size, and color of natural teeth. Fixed prosthodontic restorations are designed to restore the strength, function, and appearance of teeth. Crowns are typically used to protect and rebuild damaged teeth, while bridges replace one or more missing teeth by anchoring to neighboring teeth or implants. Treatment planning for fixed prosthodontics involves evaluating the condition of the teeth, gum health, bite alignment, and bone support. Dental impressions or digital scans are used to create precise restorations that fit properly and function within the patient’s bite.
UnderstandingÂ
Fixed Prosthodontics
Clinical Significance
Fixed prosthodontic restorations help restore chewing ability, maintain bite stability, and replace missing or structurally compromised teeth. Untreated tooth damage or tooth loss may lead to shifting teeth, bite problems, and reduced chewing efficiency.
Benefits to Treatment
Restoration of tooth strength and function, replacement of missing teeth, improved chewing ability, stable restorations that do not need to be removed, and natural looking aesthetic results.
How it Works
The dentist prepares the affected tooth or implant site and takes impressions or digital scans of the mouth. A custom restoration such as a crown or bridge is fabricated and then permanently attached using dental cement or implant components.
What it's Used For
To restore damaged teeth, replace missing teeth, strengthen weakened teeth, and improve dental function and appearance.
What Patients Can Expect
Fixed prosthodontic treatment typically involves one or more appointments. The dentist may prepare the tooth, take impressions or digital scans, and place a temporary restoration while the final prosthesis is fabricated. Once ready, the final restoration is fitted and permanently attached.
Downside
Fixed restorations may require removal of some natural tooth structure during preparation. These treatments can involve multiple appointments and may require future maintenance or replacement over time.
Frequently Asked Questions
What is the difference between fixed and removable prosthodontics?
Fixed prosthodontics uses restorations such as crowns and bridges that remain permanently attached in the mouth. Removable prosthodontics includes appliances such as dentures that patients can remove and reinsert themselves.
How long do fixed dental restorations last?
The lifespan of fixed prosthodontic restorations varies depending on the materials used, oral hygiene, bite forces, and overall oral health. Many restorations can function for many years with proper care and regular dental visits.
Are dental implants part of fixed prosthodontics?
Yes. Implant-supported crowns and bridges are commonly considered part of fixed prosthodontics because they are designed to remain permanently attached in the mouth.
Do fixed restorations feel like natural teeth?
Many patients find that well-designed fixed restorations feel similar to natural teeth once they adjust to them. They are designed to match the surrounding teeth and function within the normal bite.
How do I care for fixed prosthodontic restorations?
Good oral hygiene, including brushing twice daily and cleaning between teeth, is important for maintaining fixed restorations. Regular dental visits also help monitor the condition of the restorations and surrounding tissues.
