Fixed and removable prostheses are dental appliances used to replace missing teeth and restore oral function and aesthetics. These prostheses are designed to be durable, comfortable, and functionally efficient, allowing individuals to regain their ability to chew, speak, and smile confidently.

1. Fixed Prosthesis:
Fixed prosthesis, commonly known as dental crowns, bridges, or implants, are dental restorations that are permanently attached or fixed in the mouth. They are typically made from materials such as porcelain, ceramic, or metal alloys, and are customized to match the color, shape, and size of the surrounding natural teeth. Fixed prostheses include:

– Dental Crowns: Crowns are tooth-shaped caps that cover the entire visible portion of a damaged or severely decayed tooth. They provide strength, protection, and restore the tooth’s appearance and functionality.
– Dental Bridges: Bridges are used to replace one or more missing teeth. They consist of artificial teeth (pontics) attached to dental crowns on either side, which are then cemented onto the adjacent teeth or dental implants for support.
– Dental Implants: Implants are titanium posts surgically inserted into the jawbone, acting as artificial tooth roots. They support individual dental crowns or implant-supported bridges, providing a stable and long-lasting solution for tooth replacement.

Fixed prostheses are designed to be permanent and cannot be removed by the patient. They offer excellent stability, natural aesthetics, and are known for their durability and longevity.

2. Removable Prosthesis:
Removable prostheses, also referred to as dentures or partial dentures, are dental appliances that can be taken out and reinserted into the mouth as needed. They are used to replace multiple missing teeth or a complete arch of teeth. Removable prostheses include:

– Complete Dentures: Complete dentures are used when all teeth in either the upper or lower arch are missing. They consist of a flesh-colored acrylic base that supports a full set of artificial teeth. Complete dentures rely on suction and support from the underlying tissues and muscles to stay in place.
– Partial Dentures: Partial dentures are used when some natural teeth remain. They are made of a metal framework or acrylic base, with artificial teeth attached to replace the missing ones. Partial dentures clasp onto the remaining natural teeth for support.

Removable prostheses provide an affordable and non-invasive option for replacing missing teeth. They can be removed for cleaning, maintenance, or while sleeping, providing flexibility and convenience for the wearer.

Both fixed and removable prostheses require proper oral hygiene practices and regular dental check-ups to ensure their longevity and optimal function. Consulting with a qualified dentist or prosthodontist is essential to determine the most suitable option based on individual needs, oral health condition, and personal preferences.
