Abstract
|
|
|
Inferior alveolar nerve (IAN) block or infiltration anesthesia can be used during the dental implant placement in the posterior
mandibular region. The IAN block eliminates all somatosensory perceptions of the mandible and assures patient comfort during the placement of implants, while complications or nerve damages by implants can occur when patients cannot feel pain. Infiltrations may allow the patients to warn the surgeons when the IAN is in danger of being damaged, while it may also cause discomforts or pains during the implantation. In this study, we present a case of IAN block and infiltration in a female patient who had three teeth missing in each posterior mandibular region. Block anesthesia was used in the right side, while infiltration anesthesia used in the left side. After the surgery, the patient was instructed to record her discomfort or pain during the anesthesia or operation on the visual analogue scale. The patient preferred infiltration to IAN block as only anesthesia is being evaluated, because she considered that the acute pain by infiltration was more endurable than the dull pain by block. Nevertheless, she preferred block anesthesia when including implant placement during the evaluation because she had felt pain during preparation of the placementsite under infiltration anesthesia.
