Fixed or removable implant-supported restorations in the edentulous maxilla: literature review

Among the prosthesis designs used to treat the edentulous maxilla are fixed or removable implant-supported restorations. Since the aesthetic requirements and preoperative situation of each patient varies, controversy exists regarding prostheses' success rates and complications. The purpose of this article is to compare the treatment options and prosthesis designs with their indications and to compare implant and prosthesis success and treatment expense. This objective was accomplished through the review of reports with regard to varying design considerations and factors that influence the decision-making process and treatment outcomes.
