Okamoto T, et al. - The background factors (age, sex, implant width, implant length, implant site, number of implants placed, Periotest values at the time of implant placement, presence/absence of systemic disease (particularly diabetes), and the use of anticoagulation therapy) related to the occurrence of complications in the early stages following dental implant placement were assessed by the researchers. In patients with systemic diseases and in those receiving anticoagulation therapy, the incidence of complications was higher. Findings suggested that the occurrence of complications in the early stages after dental implant placement was influenced significantly by age. Hence, while developing the treatment strategies, this factor ought to be considered by the clinicians.
