It has been demonstrated that the osteoconductivity, hydrophilicity and biological capacity of titanium decreased over time, and this phenomenon was described as the biological aging of titanium. The aim of this study was to evaluate whether the age of sand blasted and acid-etched (SLA) titanium dental implants (duration from the production date until the date of dental implant surgery) affects marginal bone resorption and implant survival. This non-random conveniently sampled retrospective pilot study was carried out in 200 implants of 64 patients. Radiographic measurements were performed on intraoral periapical radiographs. Implants were divided into two age groups; Group 1: 0-3 months, Group 2: 36-41 months. p value < .05 was considered statistically singnificant. It was observed that ages of 41% (n= 82) of the implants were between 0-3 months and 59% (n= 118) were between 36 and 41 months. It was observed that 100% (n= 200) of the implants survived and maintained their function. The mean mesial marginal resorption measurements were 0.60 ± 0.65 mm and the mean distal marginal resorption was 0.77 ± 1.07 mm. There was no statistically significant difference between the amounts of mesial and distal marginal bone resorption according to the implant age (p>0.05). In SLA surface titanium implants with adequate initial primary stability and 3-months osseointegration period before loading, biological aging of titanium does not affect implant survival and marginal bone resorption.
