Abstract

Purpose: The aim of this retrospective cases series was to present results of post extraction immediate implantation and immediate loading at maxilla, mandible and full-mouth with follow-up from 1 to 8 years and to report on survival rate and prosthetic success of a total of 1042 implants.Material and
Methods: This study included 122 patients requiring full-arch maxilla, mandible or full-mouth prosthetic rehabilitation between June 2006 and September 2012. After the extraction of hopeless teeth, each patient received in one unique surgical session 6 to 10 implants per arch, and immediate provisional screw-retained acrylic resin prosthesis. After 4 months at mandible and 6 months at maxilla (6 months for full-mouth), the provisional screw-retained prosthesis was removed, and all fixtures were checked for stability. Then all patients received their final screwretained or cemented prosthesis (produced using CAD-CAM system) with 12 to 14 teeth (for one arch). There was 28% of screw-retained prosthesis and 72% of cemented prosthesis.Results: The Cumulative Survival Rate (CSR) reached 98% at the maxilla, 100% at the mandible and 98% when the two arches had implants placed and restored in one unique session. Implant in nondistal positions had lower risk of failure than those in distal position (HR=0.35, 95% CI: 0.13-0.90). The rate of prosthetic success remained high during the course of the follow up analysis: 100% at each end-point for the 3 options (maxilla, mandible, and full-mouth) under analysis.Conclusion: Combining immediate placement of dental implants after extractions and immediate loading of complete restorations at the maxilla, the mandible or both is a reliable alternative to more conservative approaches.
