Some people require a dental prostheses due to lack of teeth or any other circumstance. We know very well that once the first teeth come out, the bone teeth once you have lost them will not appear again and this is where prosthetics play an important role.

The problem is that many times we do not really know which prosthesis we need, if a fixed, semi-fixed or artificial prosthesis. But in order to know which one is indicated, the first thing we have to know is the difference between each of these prostheses. We use this type of denture in order to be able to see ourselves aesthetically well.

Fixed prostheses

Firstly, fixed prostheses are those that remain Permanently, so they cannot be removed. These can be cleaned in the mouth and do not generate any type of problem with the leakage of food debris. To use them you do not need to go through any type of adaptation period, which is something that usually happens with traditional prostheses, which at first can be somewhat uncomfortable even to speak. 

✔️ More security because it is fixed

✔️ More aesthetics

✔️ More Comfort


Semi-fixed prostheses

Moreover, the semi-fixed prostheses  are those that are supported by the implants and gums, which means that a series of additional settings so that it is perfectly adapted in the mouth. This type of prosthesis does are removable, which implies that in order to clean them, you have to remove them from your mouth and put them back once you have finished cleaning them.

❌ You have to take them off to clean them

❌ Less comfort


False prostheses


And finally there are artificial prostheses which are very similar to semi-fixed prostheses, but unlike these, removable prostheses are those that can replace a single or several teeth, without having to put the entire full denture. This type of denture is used more in elderly people and they are ideal to be able to recover the functionality of the mouth without having to feel those uncomfortable gaps inside the mouth due to the lack of a specific tooth. Taking this into account, we can already know what difference one from another and which is indicated in the different cases that may arise and that would force us to use a prosthesis.  


1. Fixed prostheses: types of prostheses and use of each one

We already mentioned earlier that this type of denture is completely fixed in your mouth. The dentures that are mostly supplanted by a fixed prosthesis are the crowns, bridges and veneers. Crowns are more than all those individual elements that cement the tooth or implant. This can be metallic, mixed or ceramic.

Bridges are those that replace teeth making them so perfect that they are not perceptible to the human eye. And finally there are the veneers that are fixed sheets which are located in the front part of the tooth and are used mostly in cases of breakage, interdental separations or blackening.

Notably a fixed prosthesis can also be placed on dental implants. To do this, the prosthesis is placed on one or more titanium implants, which are the ones that fulfill the role of the root, and the prosthesis is placed on this implant. Many dentists claim that this is the best option for those who want to change their teeth and it is mostly done for an aesthetic change, since the teeth are perfect.  

Fixed prostheses are divided into various types of prostheses, among which are:

The single implant

Dental Implants 3

It is the best known to patients, and it is a denture with a titanium screw included which is inserted into the maxillary bone and restores the natural tooth to the root.

Fixed Screwed Dental Prosthesis

It is a complete dental implant, the which includes the implant and dental crown. The implant is completely biocompatible with the human body, so they will not generate any type of ostointegration problem, and it has the same functions of the root, making the tooth can be fixed in such a way that you do not have to remove them at all. On the other hand, the crowns They are those that are made of porcelain or zirconia according to the requirements and tastes of the patient.

Hybrid prostheses

This type of prosthesis is one that is made of acrylic and remains fixed in the mouth thanks to dental implants. This type of prosthesis It is widely used in the rehabilitation treatment on implants, since it allows patients to feel that their teeth are fixed again, helping them to regain their aesthetics and chewing function.

Screw-retained fixed prosthesis

They are those that are fixed to the mouth by means of screws that are placed in specific places so that the new teeth do not move. These types of dentures are used for people who are completely edentulous. This type of prosthesis is carried out in order to achieve the prosthetic restoration, in order to make it look as aesthetic as possible.

2. Semi-Fixed Prosthesis: Types and Uses

Semi-fixed implant prostheses are a fantastic treatment option for people looking to replace their teeth in the upper or lower jaws. It also has the advantage of securing multiple dental implants and making them extremely difficult to dislodge while talking and eating. These removable implants have an attachment that has been incorporated into the dentures and acts as a socket and a ball, which can be adjusted according to the needs of the patients as they are hooked into place.

Semi-fixed implants must retire at night for a thorough cleaning, and should be checked by your doctor every nine to twelve months. Regular dentures get lost and wobble, requiring dental adhesive to stick in place, while a denture is tough and doesn't get lost randomly. In addition, the durability of semi-fixed dentures is for life, but they must be replaced every 3-4 years.

Certain reasons, such as inadequate bone volume or insufficient number of teeth, make some patients unsuitable candidates for fixed dental prosthetic work or implantology. Fortunately, there are other quality solutions for them. Among the types of semi-fixed prostheses we have:

Prosthetics combined with a bridge

Partial dentures can restore missing teeth and this option is ideal for those types of people who want to do that replacement. They have clasps that discreetly connect them to the front teeth, which are in turn restored with a metal-ceramic or zirconia-ceramic bridge.

Telescopic prostheses

Telescopic dentures are overdentures retained by telescopic dental crowns, which can be metallic or goldIt all depends on how the patient wants it and also on the need they have.  

Benefits of semi-fixed prostheses

Among the main advantages or benefits of this type of denture is that they are extremely inexpensive. This type of implant is considered the most economical of all. In addition, they are extremely durable, since they will not break very easily, since they do not have to be fixed on the teeth.

Also for its easy cleaning, helps you keep your mouth and even your implants clean and have good oral hygiene. Given that you can remove them, you will not have the uncomfortable time of feeling food remains inside it, but you can quickly clean it and that way they will be completely clean.

On the other hand, they do not look like fake implants, but rather they look very natural, so no one could suspect what a dental prosthesis you are using is dealing with. Finally, they are very easy to use and remove, so you can do it on your own without having to request the help of your dentist to remove it.  



3. Prosthetics: Types of prostheses and use of each one

Dentures, also commonly known as false teeth, are prepared to act as a prosthesis for missing teeth. They are often made of acrylic, nylon or metal. They can be used in place of one, several or all teeth, and they fit perfectly over the gums.

Properly fitting dentures have numerous benefits, including improving your speech, the ability to eat, and your self-esteem. also can help prevent the face from sinking over time and can offer protection to the remaining teeth. Within the dentures we have:

Partial dentures

All the partial dentures they are used if you still have some healthy teeth available. These dentures are often trimmed around the remaining healthy teeth. These clips may be visible when you speak, but they may be made of tooth-colored material to treat as little as possible that is visible to other people.

Complete dentures

All the full dentures They are used if you have lost all of your teeth, which can occur due to injury, infection, periodontitis, or another medical condition. These artificial teeth are attached to a plate that rests against the gums to prevent them from moving. Gum plates and accessories, which can be made of metal or an acrylic that matches the color of the gums, are generally not visible to others. False Tooth Adhesive can be used to help hold dentures in place.

Removable dentures

All the removable dentures They are the traditional model, and they come with a great added benefit of being easier to clean. However, they can slip out of place more easily, so dentists recommend avoiding foods that are particularly chewy, sticky, or hard. False teeth adhesive can help hold them in place, but these adhesives can be difficult to use.

Removable dentures they usually last about five years before they need to be replaced.

Flexible dentures

All the flexible dentures They are a popular alternative to traditional dentures, and are made with flexible yet extremely durable materials that can be more comfortable to wear. Thanks to the translucent resin that matches the color of your gum, do not require visible clips like you might see with partial dentures. Flexible dentures are also lighter and less bulky in the mouth. They can last around five to eight years.  

Benefits of false prostheses

This type of denture provides multiple benefits. For instance, artificial prostheses are usually very inexpensiveIn addition, the same day that you go to have them done, they do the check-up and in a short time they deliver them to you, thus avoiding the need to spend months without teeth (which is what happens with full dentures) .

Having fitted partial dentures It is very simple for both patients and dentists, since there is generally no surgery involved, but the necessary evaluations are done and that's it. Compared to dental bridge work, having partial dentures or fitted removable dentures does not cause damage to the teeth adjacent to the missing one.

With all this information, you can now have an overview of what can differentiate one prosthesis from another and which one you can use according to need. If what you are looking for is to change your teeth so that it looks better aesthetically, you can opt for a fixed prosthesis, which requires surgery but guarantees that you will have perfect teeth.

If what you want is to have a denture that partially replaces some teeth that you lost or are already in advanced age and you need to cover your mouth from missing teeth, you can opt for semi-fixed or false prostheses. The latter two serve similar functions, and the adaptation period is somewhat long. So it is up to you to decide what type of prosthesis you want to use.
