Full-arch and partial reconstruction is demanding for the clinician and a challenge for the patient. Traditionally, teeth are extracted, and implants are placed; the patient wears a provisional removable prosthesis during implant osseointegration. The patient is left to deal with a difficult transition from a fixed dentition to a removable one, albeit temporarily. This drastic alteration can generate functional, emotional, and esthetic changes for the patient, thereby making a difficult time even more challenging. Reconstructing the dentition through a staged approach has been documented and involves strategic extractions along with the placement of several implants, but leaves select abutment teeth for a fixed provisional prosthesis. This allows for the provisional prosthesis to be tooth-supported during implant integration and later converted to an implant-supported prosthesis. In this manner, the patient will benefit from a fixed provisional prosthesis throughout the treatment process. A staged approach is contingent upon a thorough periodontal and prosthetic evaluation and work-up. Success requires proper communication between the periodontist, surgeon, restorative dentist, laboratory, and patient. A team approach is necessary for success. The protocol, advantages, and disadvantages for a staged approach to a full-arch implant-supported reconstruction are discussed. The authors also present a case to show how the staged approach can be used for sextant or quadrant rehabilitation.
