Abstract

Background: Patient-related variables such as cost of treatment, length of the treatment period, and comfort provided by the interim prosthesis when treatment planning for full-arch rehabilitation are often neglected in dental publications.

Methods: Two patient cohorts were followed up longitudinally in this study: the "All-on-4 treatment concept group" and the "historical group." The number of implants, total treatment time, number of surgical procedures, number of sinus grafts, necessity for immediate provisional implants, adjusted cost associated for treatment in each group, and the quality of interim prosthesis were compared.

Results: The total adjusted cost for patients receiving All-on-4 treatment concept averaged at $42,422 ± 3860 (&OV0556;31,392 ± 2856), whereas the mean total adjusted cost for the historical group was $57,944 ± 20,198 (&OV0556;42,879 ± 2113) (P = 0.01). The difference in cost had a mean value of $7307 (&OV0556;5407) per jaw. Factors associated with complexity of treatment and patient comfort, such as the quality of interim prosthesis, number of surgeries, and duration of treatment time, all significantly favored the All-on-4 treatment concept group in comparison with conventional treatment modalities.

Conclusions: When implant rehabilitation of the total jaw is sought, the All-on-4 treatment concept should be considered the least costly and least time consuming treatment option.
