Delayed Placement Implants

Decent Essays

The immediate placement of implants into sites with the presence of infection has become an increasingly common procedure. Data from studies that have been published in the past two decades seem to suggest implant survival rates that are equivalent to implants that are placed in native, healthy osseous tissue.(3) While it is not known exactly why the rates are equivalent, some explanations can be proposed. First, when a tooth exhibiting signs of infection is removed, most of the source of that infection is also removed. In some cases, granulation tissue associated with the lesion is also removed with the root of the offending tooth. Any remaining or residual infection is subsequently removed with curettage and irrigation of the socket. Additionally, …show more content…

Overall, two of the immediately placed implants were lost, resulting in a 92% survival rate versus 100% survival rate for the group who received delayed-placement implants. These results were comparable to the outcomes of current study (95% survival rate).
In this study the OsstellTM device was selected to measure implant stability over other devices and techniques. The Osstell device proved to be the most non-invasive measuring technique with the most accurate and reproducible results.(23) Previous studies revealed that the OsstellTM was more precise than the Periotest to determine the actual dental implant stability. (24,25) The observations of the current study revealed a positive correlation between the ISQ value and the ratio of bone to implant contact detected by CBCT.
The distance between bone and implant is called peri-implant gap. The fresh socket is wider than the implant diameter, which causes the peri-implant gap that influences stability and osseointegration. (26,27) Pluemsakunthai et al.,(28) analyzed immediate
