Risk factors
p radiotherapy may induce vascular fibrosis and thrombosis, with subsequent
tissue breakdown and development of chronic non-healing wounds (epstein et
al. 1997; Wong et al. 1997). therefore, irradiated bone should be viewed
as a risk factor for implant insertion, and an adequate waiting period after
radiotherapy is recommended (esser & Wagner 1997; Jisander et al. 1997;
Granström & tjellström 1997).
p severe diabetes, especially juvenile diabetes (type 1), is considered a risk factor,
whereas patients with well-controlled type 2 diabetes do not need to be excluded
from implant therapy (shernoff et al. 1994; oikarinen et al. 1995).
p Bleeding disorders such as hemorrhagic diathesis or drug-induced anticoagulation
should be considered as risk factors for implant therapy.
p heavy smoking has been shown to adversely affect the long-term prognosis of
dental implants (Bain & moy 1993; Gorman et al. 1994; Bain 1996; haas et al.
1996; Lindquist et al. 1996).
