The Effect of Age of Titanium Dental Implants on Implant Survival and Marginal Bone Resorption: 5-Year Retrospective Follow-up Pilot Study

Cigerim L, Kaplan V

Study objectives and methods

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.

Results

• 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).

Conclusions

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.
