The periodontal, orthodontic, and prosthetic management of four indications for subgingival or subosseous tooth fractures has been discussed. The importance of having the aveolar crest a minimal distance of 2.5 mm from the margin of the restoration has been explained. The pitfalls of an external, rather than internal, bevel and flap procedure were assessed. Coordinated interspecialty therapy provides diverse, conservative treatment for the general practitioner and successful restorations for the patient.
