The different retention types for facial prostheses

Facial prostheses, also known as facial prosthetics, are artificial devices used to replace missing or disfigured facial features. These prostheses can be used to restore function, improve appearance, and boost self-esteem for individuals who have lost facial features due to cancer, injury, or congenital abnormalities.

There are several retention types for facial prostheses, each with its own unique characteristics and benefits. These retention types include:

1. Magnetic retention: Magnetic retention prostheses use small magnets embedded in the prosthesis and the patient's skin to hold the prosthesis in place. This type of retention is generally used for small facial prostheses, such as ears or noses.

2. Adhesive retention: Adhesive retention prostheses use a medical-grade adhesive to secure the prosthesis to the skin. This type of retention is typically used for larger facial prostheses, such as those used to replace a missing cheek or jaw.

3. Mechanical retention: Mechanical retention prostheses use mechanical components, such as screws or clips, to attach the prosthesis to the patient's skin or bone. This type of retention is often used for prostheses that need to be removed and reattached on a regular basis, such as those used to replace a missing eye.

4. Osseointegrated retention: Osseointegrated retention prostheses use a titanium implant that is surgically implanted into the patient's bone. The prosthesis is then attached to the implant using a special connector. This type of retention is typically used for prostheses that need to be worn for long periods of time, such as those used to replace a missing lower jaw.

Each retention type has its own benefits and drawbacks, and the most appropriate retention type for a particular patient will depend on a number of factors, including the size and location of the missing facial feature, the patient's skin type and health, and the patient's lifestyle and activity level.

In conclusion, there are several retention types for facial prostheses, including magnetic retention, adhesive retention, mechanical retention, and osseointegrated retention. The most appropriate retention type for a particular patient will depend on a number of factors, and should be carefully considered by the patient and their healthcare team.
