Hybrid dentures - Implant-supported restorations

Overview

According to The Glossary of Prosthodontic Terms (2023, Journal of Prosthetic Dentistry), the term hybrid denture is “used to describe a removable or fixed denture that is composed of different materials, types of denture teeth (porcelain, plastic, composite resin), variable acrylic denture resins, differing metals or design, etc.” Dr. Carl Misch’s classification of implant-supported prostheses FP1, FP2, FP3, RP4, and RP5, remains widely used today. Below is a short overview with example:

Fixed Prosthesis (FP)

Classification	Example	Main characteristics	Add-on modules
FP1		Fixed, teeth only. No pink tissue replacement.	Implant Module
FP2		Fixed, teeth + part of the soft tissue. Longer crowns replace part of the root and soft tissue.	Implant Module
FP3		Fixed “hybrid” prosthesis. Teeth + significant soft-tissue replacement.	Implant Module
FP3 variants	Monolithic Facial cut-back Thimble Split bar

Removable Prosthesis (RP)

Classification	Example	Main characteristics	Add-on modules
RP4		Implant-supported overdenture. Little or no mucosal load; typically on a bar or multiple stud attachments.	Full Denture, Bar Module
RP5		Implant- and tissue-supported overdenture. Common with stud, ball, or Locator-type attachments.	Full Denture, Implant Module
