Popis: Purpose: The aim of this study was to evaluate the survival rate of immediately provisionalized implants with up to 5 years follow-up. Materials and Methods: The study consisted of 226 patients, 113 consecutive patients with immediately provisionalized dental implants (cases) and 113 randomly selected, age-, gender-, and implant position-matched controls with conventional late implant loading. Survival rate and incidence of complications were recorded. Results: Follow-up ranged from 6 to 60 months. Smoking was reported by 20.8% of patients. Maxillary incisors and mandibular lateral incisors were the most common areas for implant placement. Conventionally loaded implants were narrower (p = .03) and shorter (p = .001). Immediate implantation into a fresh extraction socket was performed in 69% of the cases and in 36.3% of the controls (p = .001). Implant survival rate was 96.5%. Of the eight failed implants, six were immediately provisionalized and two were conventionally loaded. No statistically significant difference was found in survival rates between groups (p > 0.05). Five of the failed implants (case group) were immediately loaded implants placed in fresh extraction sockets.
