Implants & Problems

Dental Implantology

The breakthrough in dental implantology occurred in 1952, when research by the Swedish professor Mr Per-Ingvar Brånemark on "osseointegration" finally resulted in being able to successfully implant titanium pins as a tooth root replacement into the jaw bone of patients.

Over the years, implantology has been further improved so that currently more than 95 percent of the implants successfully grow into the jaw bone. However, long-term stability of the dental implants still is one of the main issues.

Risks of implant treatment

Today, implant therapy represents a routine treatment in many dental surgeries all over the world. Contrary to other prosthetic treatments of the human body, such as hip joints and knee joints, the dental implant is permanently located in the highly germ-loaded oral cavity. The risk of inflammation is correspondingly higher with dental implants as compared to other implants, even in case of very good healing of the dental implant in the bone. Furthermore, the gingiva into which the dental implant is embedded significantly differs from the gingiva around a natural tooth. Due to the lack of radiating tissue fibres, the gingiva is less tightly connected to the implant meaning that bacteria can penetrate more easily. Such bacteria may then cause inflammations and endanger the durability of the implant.

The following factors improve the durability of implants:

The following factors impair the durability of implants:

The following medical conditions may occur:

Peri-implantar mucositis

Peri-implantitis

Inflammation-free implants

In 2006, the Academy of Periointegration (AP) was founded to handle the risk and to develop effective concepts for long-term success of dental implants. This association of experts defined design improvements and medical-technical optimisations to ensure inflammation-free integration of implants into the surrounding gingiva also in the long term. This new principle of healthy and long-term tissue integration of dental implants has been named "periointegration" by the researchers.

Scheme of an implant
An implant usually consists of the dental prosthesis [1], the implantat extension [2] and the implant screw [3].
