Protesi dentarie metalliche? Io ho i miei dubbi...
Inviato: sab lug 03, 2010 2:52 pm
Alcune settimane fa ascolto un medico dentista in un programma televisivo che dice di evitare di fare impianti dentari per chi ha un diabete o malattie immunitarie. Questo mi ha fatto riflettere...Nelle pubblicazioni di PUBMED ci sono diversi articoli interessanti, uno è questo ma è in inglese:
Typical symptoms of methyl acylate sensitivity in wearers of acylate dentures]
[Article in Hungarian]

Abstract
Between 1986. and 1995. 150 patients were patch tested who had developed allergic reactions to their prosthesis made from acrylate. Three patients are described, whose history and patch test results confirmed the hypersensitivity to methylmetacrylate. The typical symptoms of acrylate sensitivity are discussed. After the removal of acrylate prosthesis and replacement with polyamide base (Valplast) prosthesis, the symptoms disappeared. Because the number of allergic reactions increases, the authors emphasize the necessity of prescreening in suspected cases of acrylate allergy.

Abstract
The multipiece nature of different implant systems is problematic for a number of reasons. The greatest challenge is bacterial colonization of the implant and of the surrounding tissue, because of the implant/abutment and abutment/crown interfaces, as well as the micromovements of the individual components of the implant. A possibility of eliminating microgaps between the individual components of the implant on the one hand and avoiding micromovements on the other is described in this paper.
