Dentures can be applied in different ways depending on factors such as the patient's mouth structure, age, expectations, and lifestyle. These can be listed as follows:

**Removable dentures:** The term removable denture refers to the patient's ability to remove and replace the prosthesis themselves. These types of dentures are supported by the remaining teeth in the mouth as well as the soft tissues surrounding the teeth. With the chewing load on the denture, the soft tissues in the mouth are embedded to a certain extent, i.e., they move. Removable dentures are made for cases ranging from a few missing teeth to cases where all teeth are missing, depending on the location and number of missing teeth in the mouth.

In cases where the patient still has their own natural teeth in their mouth, removable dentures made with support from these teeth and soft tissues are called "Partial dentures," while in cases where all natural teeth are missing, the type of removable denture that is supported only by the gums and palate is called a "Complete denture."

**Partial denture:** These are removable dentures that fill the space of missing teeth, using metal clasps (clasps) or special retainers to attach to existing natural teeth, using fabricated artificial teeth in place of the missing teeth.

Patients using partial dentures need to take even more care of their oral hygiene than before. Partial dentures are held in place by metal clasps or prefabricated precision attachments to the remaining natural teeth in the mouth.

Precision attachments are more aesthetic but more expensive than clasp dentures. The fabrication time for partial dentures using precision attachments is longer than for clasp partial dentures, and some of the remaining natural teeth may need to be covered.

**Complete denture:** This is the type of denture made for patients who have no remaining teeth. Complete dentures are usually made from a gum-colored material called acrylic (polymethyl methacrylate), and very rarely, in special cases, they are made with metal support. The artificial teeth placed on this substructure are usually made of acrylic or composite materials and are readily available on the market. The use of porcelain teeth in complete dentures depends on special circumstances. It is appropriate for the dentist to decide on the material to be used.

Complete dentures are the most difficult type of denture to use, both because they are supported only by the soft tissues in the mouth and because of the psychological discomfort the patient experiences from losing all their natural teeth. In addition to the loss of chewing, taste, and the pleasure of eating certain foods, problems that may arise during use will also bother the patient. The patient must accept that they are now a complete denture wearer and that they must protect the jaw bones and soft tissues that support this denture. The jaw bones that hold the tooth roots begin to resorb after tooth loss. This resorption of bone will continue throughout life. Reducing bone resorption depends on the patient following their dentist's recommendations and using their denture carefully.
