Fixed dentures :
It represents the insertion of a prosthetic appliance within the jawbone and can only be removed by the dental surgeon. This device will aim to fill the space left by the missing tooth. It is thoroughly designed to correspond in every way to the original tooth.
What are the advantages of a fixed dentures ?
Feedbacks on prostheses of this fixed type are very positive although they face fierce competition from removable prostheses. The impression of chewing, grinding and crushing is reproduced identically. Yet, even with the advantage of even less worrying about the state of the tooth or cavities, do not let the idea take you to have all your teeth replaced!
The advantages of fixed prostheses are specific to each type, however, they are generally attributed to:
- An indisputably long validity of use: the lifespan of the prosthesis is 10 years averagely as long as its user takes care of it which may extend its longevity to 12 years. A rigorous and meticulous brushing of the oral cavity by passing the brush over each tooth without omitting the prosthesis.
- Since it respects the shape, color and appearance of the natural tooth, the prosthetic device goes unnoticed by the adjacent teeth, which represents an undeniable aesthetic advantage in addition to the functional restoration.
What are the types of a fixed dentures ?
Here are several types of fixed dentures:
- Dental Bridge :
A traditional dental bridge consists of artificial teeth (pontics) that are attached to crowns placed on the natural teeth on either side of the gap. This bridge is permanently fixed in place and cannot be removed by the patient. - Cantilever Bridge:
Similar to a traditional bridge, a cantilever bridge is supported by a natural tooth on only one side of the gap. This is a less common type and is typically used when there is only one adjacent tooth available for support. - Maryland Bridge (Resin-Bonded Bridge):
This type of bridge is composed of a pontic held in place by metal or porcelain wings that are bonded to the adjacent natural teeth. It is a conservative option as it involves minimal preparation of adjacent teeth. - Implant-Supported Bridge:
Instead of relying on natural teeth for support, an implant-supported bridge is secured onto dental implants surgically placed in the jawbone. This type of fixed denture is stable, durable, and provides support without affecting adjacent natural teeth. - Implant-Supported Hybrid Denture (All-on-4, All-on-6):
This is a full arch restoration that is fixed onto dental implants. It is often used for patients who are missing all or most of their teeth. The “All-on-4” or “All-on-6” refers to the number of dental implants used to support the denture. - Implant-Supported Overdenture:
Similar to implant-supported bridges, implant-supported overdentures are removable prostheses that clip onto dental implants for stability. They provide more retention compared to traditional removable dentures. - Fixed Hybrid Denture:
This is a combination of fixed and removable elements. It typically involves a fixed bridge in the anterior (front) region and a removable section towards the posterior (back) of the dental arch. - Metal-Ceramic Fixed Partial Denture:
This type of bridge combines the strength of metal with the aesthetics of ceramic. It involves a metal substructure covered with porcelain for a natural appearance.
The choice of fixed denture depends on factors such as the number of missing teeth, the condition of remaining teeth, patient preferences, and budget considerations. Our expert dentists can assess individual cases to recommend the most suitable type of fixed denture.
For whom the fixed dentures is designed?
The use of dentures is inevitable when attempts to repair the ineffective tooth have failed. The situations in which we alter the damaged tooth follow these conditions:
- Dental caries: a direct consequence of poor oral hygiene, caries dig into the enamel of the tooth and advance until it weakens the entire structural integrity. The tooth, therefore, becomes unable to carry out its role of grinding food.
- Periodontitis: it is the dental condition that affects the gums and causes a chronic inflammation state whose most common signs are redness, sensitivity, and sometimes dental bleeding. This inflammatory condition disrupts the oral microbial balance and leads to instability of the fibers that support the tooth. In the absence of specialized care, edentulism is inevitable.
Removable dentures :
Unlike a fixed dental device, the removable denture, as its name suggests, can be removed by the patient. This latter will have a free will in terms of portal. The denture is a removable prosthesis which will aim to replace one or more missing teeth while having autonomy.
What are the types of removable prosthesis?
The different therapies available to the dental surgeon are conditioned by the stage of edentulism, we find:
- The complete removable denture : this is intended for people who have completely lost their upper or lower teeth or even both at the same time. A 3D digital impression will be taken beforehand in order to produce a personal material that is in accordance with your oral anatomy. The prosthesis will be fixed on the gum by the effect of pressure and suction although in certain situations that are refractory to adhesion, the dental surgeon will add a button and pressure system in order to ensure optimal comfort by maintaining the structure stable.
- The partial removable dental prosthesis: it is designed for people who haven’t completely lost their teeth. In this situation, the prosthesis will be placed between the natural teeth. The stability of the prosthesis is guaranteed by hooks which grip the teeth on either side. The entire structure offers a combination of homogeneous appearance that is highly appreciated by its users. The discretion of partial removable prosthesis allows it to find an almost normal functionality as well as an adjustment of speech defect.
In general, it is advisable to remove partial dentures at night before going to sleep. Allowing the gums and remaining teeth to have a break from the pressure of the partial denture can contribute to oral health. Removing the partial denture at night also gives the oral tissues a chance to recover and can help prevent issues like irritation, soreness, and fungal infections.
The choice between veneers and dentures hinges on specific dental needs and individual goals. Veneers are optimal for cosmetic enhancements, addressing issues like discoloration and minor misalignments on existing, healthy teeth, with minimal tooth reduction. On the other hand, dentures serve as a comprehensive solution for significant tooth loss, offering both functional and aesthetic restoration. Dentures are removable and may be more cost-effective for extensive tooth loss. In some cases, a combination of veneers and dentures may be recommended to address both cosmetic and restorative needs.
Dentures can be made from various materials, each with its own set of advantages and considerations. The two main types of materials used for dentures are:
Acrylic Resin: This is the most common material for the base of dentures. It is durable, lightweight, and can be color-matched to the natural gum tissue. Acrylic resin dentures are typically more affordable and easier to adjust if necessary. However, they may be bulkier than other materials.
Porcelain or Ceramic: Porcelain or ceramic teeth are often used for the artificial teeth on dentures due to their natural appearance and wear resistance. While they provide a realistic look, they are more prone to breakage and are heavier than acrylic resin. Porcelain dentures are less commonly used today.
Additionally, some dentures may incorporate a metal framework for added strength and stability, especially in partial dentures. Flexible resin materials are also available, providing a more comfortable fit.
