Nu brinner det i knutarna för amalgamisterna världen över! FDI, ADA, BDA och övriga belackare börjar inse vidden av UNEP:s kvicksilverkonferenser och att amalgamets dagar därför är räknade. På FDI konferens i Mexiko ska man ge tandläkarna “argument” för amalgam och hur de ska “hantera” frågan med patienterna och i media i respektive land. Undrar om FDI tänker utbilda tandläkarna i hur man tar till sig nya tekniker, istället för att försvara användningen av ett dentalt material ifrån antiken.
FDI Conference on ancient material
A tremendous amount of materials (e.g. amalgams, composite
resins, compomers, ceramics, metal alloys) together with different
adhesive techniques are available today. Market approval (responsible:
manufacturer) for these materials is based on clinical and preclinical
testing. For the selection of the appropriate material in the individual
situation the dentist is responsible. Selection is based on the necessary
technical material properties, but also on the individual psychological
and medical situation of the individual patient. Risk factors like allergies
are identified by special anamnesis, clinical examination possibly
combined with individual testing. Patients are involved in the selection
process through proper health risk communication.
? Discuss: whether amalgam still a topic and detail the rationale
behind the argument
Current innovations aim at improved aesthetics and conservation
of sound tissues (minimal/non invasive technique). For composite
resins polymerization shrinkage has been reduced through improved
filler technology and even more through new resins (e.g. siloranes).
However, special adhesives are needed and x-ray opacity is limited.
New dental adhesives combine different chemicals into one bottle
facilitating application. However, bond strength is lower compared
to multi-bottle systems. Improved aesthetics has become possible
through improved ceramics (e.g. CAD/CAM fabricated), but costs are
high. Therefore, always newer does not mean always better and even
the well established amalgam remains part of our dental materials
armamentarium.
There will be significant changes in the dental material landscape over
the next few years driven by the shift towards a preventive model of
oral health care (FDI?s Global Caries Initiative) and the United Nations
negotiations covering dental amalgam.
This session will provide general practitioners with essential information
on current dental restorative materials, as well as the background to
the United Nations negotiations.
The debate will explore the potential implications for general
practitioners, how they can be involved in these changes and
communicate with their patients on this issue with confidence.
