Abstract Acid‐etch retained appliances have a role in the management of dental trauma, both as splints and for the replacement of missing teeth. Two clinical cases are described. In the first, a tooth with a fractured root is used as an abutment for a bridge that replaces an avulsed tooth. The metalwork is modified with a “window” to facilitate endodontic therapy should this become necessary in the future. In the second case, an etched splint with a “window” supports a tooth of poor prognosis while an endodontic implant is placed and healing occurs. Further designs are considered for applications in similar circumstances.
