OBJECTIVES/AIM: To analyze and compare costs of different prosthetic rehabilitations for the edentulous maxilla.
Patients with edentulous maxillae were rehabilitated with either of three implant-supported prosthetic protocols; removable overdenture supported by 2 implants (ISOD 2), fixed dental prostheses supported by 4 (ISFAFDP 4) or 6 (ISFAFDP 6) implants. Cost of treatment and costs during follow-up were registered and compared.
Twenty-four patients were included: six patients received ISOD 2 treatment, eight patients received ISFADP 4 treatment and ten patients received ISFADP 6 treatment. Initial costs for ISFAFDP 6 were higher than costs for ISFAFDP 4 and ISOD 2, but there were no differences in cost for maintenance i.e., the ISOD treatment remained the least costly treatment alternative after 1-year follow-up.
The lack of difference in cost for maintenance and repair over the first year suggests that implant-supported overdentures will remain the least costly treatment option for the edentulous maxilla, at least in a short-term perspective.
Removable maxillary overdentures supported by 2 implants may be a valid low cost treatment option.
分析和比较上颌无牙颌不同修复方式的成本。
上颌无牙颌患者采用三种种植支持修复方案中的一种进行修复；由2颗种植体支持的可摘覆盖义齿（ISOD 2）、由4颗（ISFAFDP 4）或6颗（ISFAFDP 6）种植体支持的固定义齿。记录并比较治疗成本和随访期间的成本。
纳入24例患者：6例接受ISOD 2治疗，8例接受ISFADP 4治疗，10例接受ISFADP 6治疗。ISFAFDP 6的初始成本高于ISFAFDP 4和ISOD 2，但维护成本没有差异，即ISOD治疗在1年随访后仍是成本最低的治疗选择。
第一年维护和修复成本无差异表明，至少从短期来看，种植支持覆盖义齿仍将是上颌无牙颌成本最低的治疗选择。
由2颗种植体支持的上颌可摘覆盖义齿可能是一种有效的低成本治疗选择。
