Abstract

Purpose: The aim of this prospective study was to assess survivability of dental implants placed using robotic computer aided implant surgery via Yomi® (Neocis, Inc. Miami, FL) after at least 1 year of functional loading. Secondary analysis included additional success and marginal bone loss outcomes after at least 1 year of functional loading of the same Straumann (Basel, Switzerland) titanium dental implants that were placed with the r-CAIS workflow. Materials and Methods: Since acquisition of the Yomi® robotic system, a comprehensive list of patients who underwent dental implant therapy via r-CAIS methodology at West Virginia University Department of Graduate Periodontics was kept and recorded. After inclusion and exclusion criteria were applied, 27 patients with 40 implants were called back for a short-term follow-up to assess the condition of their implants. This evaluation included patient level, site level, implant level, and OHIP-14 data for an overall summation of changes and health of the dental implants since functional loading. These implants were restored with a combination of screw retained single implants and fixed cross arch splinted prostheses. Results: 14 patients with 23 dental implants were available for examination. All implants were Straumann SLA treated surfaces. Mean age at follow up was 72.6 years old (range 26-80 years). The mean time of placement to follow up was 51.31 months (range 41.2-65.73 months) and the mean time of implants in function was 38.65 months (range 27-64 months). Since placement, no implant complications were noted. Only one implant showed minimal signs (0.9mm) of periimplant bone loss apical to the implant platform but was clinically healthy. No implants showed signs of peri implant mucositis or peri implantitis. All 23/23 (100%) implants were still surviving and successful. The average change in marginal bone level from initial radiograph to the follow up was +0.35mm +/- 0.58 (range -0.5mm – 1.4mm). The mean probing depth was 2.35mm (range 1-4mm), the mean number of bleeding sites was 2.4% (2/84 available sites), 0/23 sites had evidence of suppuration or pain. Prosthetic complications were noted in 3/23 implants including abutment fracture, wear, and crown mobility. Conclusion: R-CAIS workflow presents as a viable solution for the dental practitioner. The present prospective analysis resulted in a mean 4.27-year survival rate of 100% and success rate of 100% of implants placed with the Yomi® dental implant robot. In addition, the relative changes in marginal bone level increased by +0.35mm over time.
