PDF: Immediate Loading of Single-Tooth Implants in the Posterior Region

The aim of this study was to evaluate the clinical response and safety of immediately loaded single-tooth implants placed in the posterior region of the maxilla and mandible.

In implant dentistry a stress-free healing period is generally accepted as a prerequisite to achieve bone apposition and implant integration without the interposition of fibrous scar tissue. 

Traditional guidelines for attaining osseointegration include up to 6 months of nonloaded healing time. This concept was introduced by Brånemark and coworkers in 1977.

As a result of refined surgical protocols, an optimized implant design, and other surface characteristics, a shortened healing period is currently possible. 

Immediate loading of implants that are cross-archstabilized with either a rigid bar or a fixed provisional prosthesis have been reported by several authors. The success rate of this treatment is comparable to that for conventionally loaded implants. 

Unlike previous investigations of immediate or early loading, this study presents a single-tooth implant protocol in posterior sites with unsplinted implants. 

The aim of this study was to evaluate the clinical response and the predictability of immediately loaded single-tooth implants. 

Since dental implants must withstand relatively high forces and loading moments in function in the posterior, a better understanding of in vivo bone response to immediate loading of single-tooth implants is needed.
