A 73-year-old Korean female patient with a fully edentulous mandible was planned to have five implant fixtures installed in the anterior mandible for the fixed prosthesis. After 3-dimensional (3D) computed tomographic scanning was transferred to OnDemand3Dⓡ (Cybermed Co., Seoul, Korea) software program for the virtual planning, five fixtures of MK III Groovy RP implants of Branemark Systemⓡ (Nobel Biocare AB Co., Goteborg, Sweden) were installed in the anterior mandible between both mental foramens using In2Guideⓡ (CyberMed Co., Seoul, Korea) mucosa-supported surgical template with Quick Guide Kitⓡ (Osstem Implant Co., Seoul, Korea) systems. Fixture installations were completed successfully without any complications, such as mental nerve injury, bony bleedings, fenestrations and other unexpected events. Postoperative computed tomographic scans were aligned and fused to the planned implant, then angular and linear deviations were compared with the planned virtual implants. The mean angular deviation between the planned and actual implant axes was 3.422±1.336o. The mean distance between the planned and actual implant at the neck area was 0.544±0.290 mm horizontally and 0.118±0.079 mm vertically. The average distance between the planned and actual implant at the apex area was 1.166±0.566 mm horizontally and 0.14±0.091 mm vertically. These results could be considered more precise and accurate than previous reports, and even our recent results. The entire procedures of this case are reported and reviewed.
