Abstract

Objective: To evaluate the background factors related to the occurrence of complications in the early stages after dental implant placement.

Materials and methods: A total of 289 outpatients who received dental implants were retrospectively evaluated for the presence or absence of complications. Background factors, including 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, were compared between patients with and without complications. Logistic regression analysis was performed to identify significant risk factors for the occurrence of complications after dental implant placement.

Results: Complications in the early stages after dental implant placement occurred in 25 (8.65%) patients. The patients with complications were older than those without complications (P = 0.003). In addition, the incidence of complications was significantly higher in patients with systemic diseases (P = 0.004) and in those receiving anticoagulation therapy (P = 0.005). Logistic regression analysis revealed that age was a significant risk factor (P = 0.025) for early-stage complications, whereas the number of implants, presence of diabetes, and the use of anticoagulation therapy were not significant risk factors.

Conclusions: Our results show that age is a significant factor influencing the occurrence of complications in the early stages after dental implant placement. Therefore, clinicians should consider this factor when developing their treatment strategies.
