Ridge split for implant placement in very thin alveolar ridge

For implant treatment there must be sufficient bone to house the implant body. At least 5mm wide residual bone is needed and usually a 6mm width is preferred by clinicians. However, surgeons sometimes find patients with a narrow ridge, which makes it difficult to place an implant. Therefore, many clinicians perform bone graft or a ridge splitting technique to overcome these poor conditions. The time and cost can be reduced using the ridge splitting technique with immediate implant placement. Recently, many studies reported reliable consequences of ridge splitting technique. This paper reports a successful of implant placement with a ridge splitting technique in a very thin alveolar ridge.

Transient Neurological Syndrome after Bupivacaine Spinal Anesthesia: A case report / 대한마취과학회지

Transient neurological syndrome often occurs after spinal anesthesia with lidocaine, but relatively infrequently with bupivacaine. We describe a case of transient neurological syndrome, which occurred after spinal anesthesia with 15 mg of 0.5% bupivacaine. Transurethral resection of the bladder was performed in the lithotomy position. There were no problems during the spinal anesthesia and surgery. However, the first day after surgery, the patient complained of paresthesia and pain over the L4-5 dermatomes in both legs, but without decrease of muscular strength. The senses in this area returned to normal over the following 2 weeks. Even though this one case of a patient with transient neurological syndrome after bupivacaine spinal anesthesia is reported, the authors still consider bupivacaine relatively safe for spinal anesthesia.
