The All-on-4 Implants Concept: A Review and Update

Abstract

Implant placement is a challenge in the deficient bone mass in maxilla and mandible. If the available bone is reduced, then
esthetics is challenged. The ideal implant position should be considered in all three dimensions: Mesiodistal, apicocoronal,
and orofacial. In DBM condition, All-on-4 implant concept may be the answer whenever patient is motivated for fixed full
mouth rehabilitation as implant-supported fixed prostheses. All-on-4 implants concept, four implants are placed anteriorly. The
current article is a review and update article over the same and it will reveal the planning protocol, consideration of salient
factors, and surgical and prosthetic protocol. In summary and conclusion, this concept eliminates the need of sinus lift and
grafting, damage of mental nerve, indication for design for manufacturability type of bone, and cost effective. It also reduces
the period of edentulism.
