“Contrary to previous assumptions, bone loss among these patients was not linear but instead progressed more quickly as time passed. This is an entirely new discovery, which shows how important it is to quickly discover and rectify implant-related bone loss," says specialist dentist Christer Fransson, who wrote the thesis.
Smoking is one of several factors to increase peri-implantitis-associated bone loss. The study showed that smokers had more implants exhibiting signs of bone loss than did non-smokers.
The thesis also shows that the mucous membrane around implants with bone loss is often inflamed.
“It is important to examine the tissue around the implant in the same way that the tissue surrounding the teeth is examined. This makes it possible to discover early signs of inflammation and to implement treatment before bone loss results in serious consequences," says Christer Fransson.
FACTS, DENTAL IMPLANTS
Hundreds of thousands of Swedes have dental implants — a sort of artificial tooth root made of titanium. The titanium screw is operated into the jawbone and takes root there, for subsequent use as an anchorage for dental crowns, bridges or dentures. There are different titanium implant variants, but all are based on the fact that the metal, titanium, has the unique ability to take root in the bone. The method was invented by Professor Per-Ingvar Brånemark at the Sahlgrenska Academy during the 1960s.
