[Provisional implants for immediate overdenture fixation after multiple tooth extraction]

The aim of the study was to assess the effectiveness of immediate overdenture supported by provisional mini-implants after multiple tooth extraction. The study included 39 patients aged 55±17, followed up for 12 months. The first group included 14 patients with 65 mini-implants and 17 soft-lined immediate overdentures. In the second group (10 patients, 45 mini-implants) 12 immediate overdentures had hard liner. In the third group (15 patients) immediate overdentures with hard liner were used without implant support. 12-month implant survival was 98.5% in the I and 91.1% in the II group (1 and 4 implants failed correspondently). The number of denture basis corrections was minimal in the second group (2.9±0.46) and largest in the third group (4.32±0.67). Mini-implants provided better fixation of complete denture, facilitated mucosal adaptation to denture compared with immediate dentures without implant support.
