Current State of Evidence for Implant Placement and Loading in Partially Edentulous Patients: A Systematic Review
German O. Gallucci, Adam Hamilton, Samuel Akhondi, Kevser Pala, Juan Francisco Peña‐Cardelles

TL;DR
This systematic review evaluates the success rates of different implant placement and loading protocols in partially toothless patients, finding that some protocols are well-supported while others need more evidence.
Contribution
The study provides updated survival rates and validation status for various implant placement/loading protocols in partially edentulous patients.
Findings
Type 1C (immediate placement + conventional loading) and Type 4C (late placement + conventional loading) show high survival rates and are clinically validated.
Protocols Type 1A and Type 2–3A now show validated survival rates, expanding evidence for immediate and early implant placement.
Type 1B and Type 2–3B have insufficient evidence despite high survival rates, requiring careful patient selection.
Abstract
To systematically review the updated evidence for the clinical outcome of fixed implant prostheses treated with different combinations of implant placement and loading protocols in partially edentulous patients. An electronic search was performed in Medline, Embase, and Central to identify studies of implants subjected to immediate placement + immediate restoration/loading (Type 1A), immediate placement + early loading (Type 1B), immediate placement + conventional loading (Type 1C), early placement + immediate restoration/loading (Type 2–3A), early placement + early loading (Type 2–3B), early placement + conventional loading (Type 2–3C), late placement + immediate restoration/loading (Type 4A), late placement + early loading (Type 4B), late placement + conventional loading (Type 4C) with implant‐supported fixed dental prostheses (IFDPs) in partially edentulous patients.
