Micro preemies usually undergo arterial catheterization for frequent blood pressure monitoring and blood sampling. Peripheral tissue injury associated arterial catheterization is a well-described morbidity observed in neonates. Despite the potential permanent disability associated with this complication, the currently available therapeutic options remain limited. We report a unique case of a preterm infant who developed severe tissue ischemia after arterial catheterization of the radial artery and was successfully treated using extensive humidification and topical nitroglycerin ointment application over an extended period (36 days) until complete clinical recovery.

To obtain better esthetic results when immediately placing a dental implant, the soft tissue surrounding the implant must be conditioned during healing of the extraction socket. To this end, the emergence profile can be customized through immediate restoration of the provisional prosthesis, and good clinical results can be obtained at the time of definitive restoration in the future, resulting in high patient satisfaction. In this case, horizontal root fracture occurred after trauma to both maxillary central incisors.Immediate implant placement and loading was planned considering aesthetics and alveolar bone condition. By taking an impression using a digital intraoral scanner, a digital diagnostic wax-up was performed to make a more aesthetic prosthesis without applying external force to the traumatized teeth. Based on this, the ideal placement location was determined and immediate implant placement was performed using a 3D printed surgical guide. The provisional prosthesis was restored 5 days after placement, and the definitive zirconia crown was restored through soft tissue conditioning and customization using the shape of the provisional prosthesis for 3 months.
