Abstract

Background: The treatment of patients by the use of immediate implant placement in post‐extractive site is a challenging procedure. / Purpose: A 3‐year clinical and radiological study of post‐extractive implants placed using flapless guided surgery and immediately functioning. / Materials and Methods: Thirty‐two patients (23 females and 9 males), aged between 44 and 73 years (a mean age of 59.5) were treated with immediate full arch restorations and flapless implant surgery in fresh extraction and healed sites. A double‐guide technique stent in conjunction with the NobelGuide system (Nobel Biocare AB, Göteborg, Sweden) was used. / Results: A total of 285 implants over 32 patients were assessed. The patients were clinically and radiologically followed for 3 years. One hundred and ninety‐five implants were placed in the maxilla and 90 in the mandible. Eight patients received implants in both arches. One hundred and ninety‐seven implants were placed in extraction sites (137 maxilla, 60 mandible) and 88 in healed sites (58 maxilla and 30 mandible). The overall cumulative implant survival rate (CISR) was 97.54%. Two implants failed in maxillary healed sites (CISR 96.55%), three in maxillary extraction sites (CISR 97.81%), and two in mandibular extraction sites (CISR 96.66%). No implant failed in healed mandibular sites (CSR 100%). All fixed prostheses maintained stability and good functionality during the follow‐up, accounting for a cumulative prosthesis survival rate (CPSR) of 100%. The overall marginal bone level (MBL) was −0.52 mm (SD −0.18) after 6 months, −0.88 mm (SD −0.20) after 12 months, −1.05 mm (SD −0.21) after 24 months, and −1.32 mm (SD −0.41) after 36 months. / Conclusions: Computer‐guided surgery using double‐template technique (DTT) shows a predictable outcome in the medium term, decreasing treatment timing and patient discomfort.
