IMMEDIATE IMPLANTS PLACEMENT & IMMEDIATE LOADING WITH FULLY DIGITAL FABRICATED IMPLANTS-SUPPORTED PROSTHESIS. A CONTROLLED CASE SERIES

Abstract

Objective: The purpose of this prospective case series was to evaluate the clinical results of immediate implant loading using three-dimensional surgical planning software. Materials and methods: The study included 84 patients that were treated by using computer 3D-planning and a consecutive immediate loading surgical protocol. All implants were and rehabilitated with a fixed CAD/CAM manufactured temporary structure. A total of 356 implants were placed, 67 of which were inserted directly into extraction sockets. The clinical indices included the following parameters: ISQ (Implant Stability Quotient) and, MBL (Marginal Bone Level). Results: Only minor prosthetic complications were recorded. When installing implants, the average value of ISQ records was 62.8 and 74.6 ISQ after 5 months, respectively. All patients reached the 60-month follow-up period, after 12 months the average value of marginal bone MBL) was 091, ± 0.25. After 36 months the average value of MBL was 1.08 ± 0.42 mm. At the interval 60 months the average MBL value was 1.25 ± 0.37 mm. The cumulative survival rate was 97,8%. The results confirm the effectiveness of this surgical and prosthetic protocol. Conclusions: Computer 3-dimensional virtual planning, in combination with immediate implant placement and immediate loading of temporary structures using CAD/CAM structures; allowed for a short treatment process with predictable aesthetic and functional results.
