This article describes indications for treatment with telescopic restorations on patients with periodontally and endodontically compromised dentitions that require splinting, with special emphasis on treatment that restores the entire dental arch. Stabilization of compromised teeth with fixed splinted restorations is usually inadvisable because of the risk factors involved, such as eventual localized abutment failure. Detachable telescopic prostheses may be preferred as a near equivalent or substitute because they can be detached and repaired without reconstruction of the entire restoration. Retentive and splinting properties of detachable telescopic restorations can be as effective as FPDs. Inner telescopic copings can be cemented as individual crowns to facilitate the procedure. Telescopic restorations can be retrieved by the patient for cleaning and easy access to the entire marginal periodontal circumference of the abutments. This promotes effective home care and oral hygiene. In addition, principles of design and indications, as well as technical and clinical factors, were discussed.
