Intraligamentary anaesthesia as a possible anaesthetic option in oral implantology: a retrospective analysis

Abstract This investigation was conducted to analyse the usefulness of intraligamentary anaesthesia (ILA) as an alternative anaesthetic procedure in oral implantology. Forty consecutive patients with single-tooth gaps in the posterior mandible were included in the analysis. Implant insertion was performed after ILA of the gap-delimiting teeth (two injections distal to the mesial tooth, two injections mesial to the distal tooth). Implant surgery was performed successfully under ILA of the gap-delimiting teeth in 39 cases. Injection pain correlated significantly with lower periodontal probing depths (
