Computer-Guided Intraosseous Anesthesia as a Primary Anesthetic Technique in Oral Surgery and Dental Implantology

Background/Objectives: The inferior alveolar nerve block (IANB) is widely used for dental anesthesia; however, issues such as anatomical variation and inflammation can hinder effective pain control. Alternatives have been studied primarily in irreversible pulpitis, with limited data available for other procedures. Methods: In a retrospective analysis, data from 85 patients who underwent implantation, root resection, or osteotomy using QuickSleeper® intraosseous anesthesia (IO), infiltration (INF), or IANB were assessed. Results: IO, IANB, and INF produced similar pain levels during administration, procedure, and recovery; blood pressure and heart rate were comparable. IO and INF led to less lip numbness after 15 minutes and required less anesthetic. IO had a significantly shorter latency than IANB, allowing earlier surgery. Conclusions: Computer-guided IO is a viable alternative to IANB for implantation, root resection, and osteotomy, offering equal pain control, shorter latency, earlier surgery, and reduced injection volume.
