Types of Dentures and Their Characteristics: 

• Complete dentures: are used when necessary to replace all missing teeth, gums, and tissues.
• Partial removable dentures: are employed to replace some missing teeth and are removable.
• Partial fixed dentures (Implant-Supported Bridge): replace some missing teeth and can’t be removed by the patient.
• Implant retained dentures (Overdentures): add retention and provide an anchorage for the false teeth to connect to when in the mouth. 
• Immediate (Same Day) dentures: allow for tooth extractions and denture installation in the same day.
