A Retrospective Analysis of Maxillary Overdentures with Non-Splinted Implants

Maxillary implant overdentures with non-splinted implants, as demonstrated in this retrospective study, showed high implant survival rates comparable to those in previous studies. However, the prosthesis survival rate was lower than reported in the literature for maxillary implant overdentures with splinted or non-splinted designs. It is recommended that the opposing dentition be sufficiently considered in treatment planning to reduce overloading factors and resultant technical complications.
