Abstract
Objective
To study the performance of 2 to 3 posterior bone‐level dental implants constructed with either 3 non‐splinted crowns (NSC), 3 splinted crowns (SC), or a 3‐unit fixed partial denture supported by 2 implants (FPD)
Material and methods
Patients treated with 3 metal‐ceramic NSC, SC or a 3‐unit FPD were included in the present retrospective study. Implant survival and success rate as well as all biological and technical complications were collected. The cost associated with each of the treatment options was evaluated in the comparative analysis.
Results
One hundred forty‐five patients (40 NSC, 52 SC and 53 in the FPD) receiving 382 bone level implants (120 NSC, 106 FPD and 156 SC) were included (mean follow‐up of 76.2 months). Lack of success was observed in 33.8% of the total patient sample, being lower in the FPD group. Implant survival rates were 92.5% in the NSC, 100% in the FDP and 88.5% in the SC, with significant difference noted between the FPD and SC (p=0.01). Overall, 9.9% of the total implants were found to have peri‐implantitis (PI), with 16.7% in the SC, 7.5% in the NSC and 2.8% in the FDP. Patients presenting prosthodontic complications were significantly higher in NSC (32.5%) than FPD (13.2%) and SC (15.4%). The total cost of the FPD group was significantly lower when compared to the NSC and SC groups (p<0.001).
Conclusions
An implant‐supported FPD seems to present the most ideal long‐term therapeutic solution in rehabilitating a 3‐unit edentulous area
