Comparison of Implant Survival Rates and Biologic and Mechanical Complications with Implant-Supported Fixed Complete Dental Prostheses Using Four and Six Implants
This study aims to compare the incidence of biologic and
mechanical complication rates and the survival rates after at least 5
years of implants and implant-supported fixed complete dental prostheses
(IFCDPs) placed during second-stage surgery using four and six
implants. A total of 77 patients (33 men, 44 women) with a mean age of
60.6 ± 8.8 years (range: 39 to 80 years) were included, and the total of
92 IFCDPs were classified into two groups: 51 received four implants,
and 41 received six implants. No implant failed in the four-implant
group (0/204), and one implant failed in the six-implant group (1/246),
with no statistic ally significant differences (P> .05). One
prosthetic failure occurred in the four-implant group (1/51), and one
failure occurred in the six-implant group (1/41). Both groups
experienced some technical and biologic complications, with no
statistically significant differences between the groups (P>
.05). For both groups, veneer or resin fracture was the most frequent
mechanical complication, and mucositis was the most frequent biologic
complication. The use of four or six implants may represent a
predictable treatment option in the rehabilitation of completely
edentulous patients with IFCDPs in the medium-term.
