Nano-scale surface modification of dental implants – An emerging boon for osseointegration and biofilm control

DOI: 10.2478/amma-2022-0029

Implant therapy is a commonly based method of replacing missing teeth. A range of physical, chemical, and biological modifications have been applied to the surface of titanium implants to improve their biological performance and osseointegration outcomes. Implant surface characteristics play an important function in several peri-implant cellular and molecular mechanisms. Clinicians are commonly placing dental implants with various surface roughness and modifications including plasma-sprayed, acid-etched, blasted, oxidized, hydroxyapatite-coated, or combinations of these procedures. Surface modifications are to facilitate early osseointegration and to ensure a long-term bone-to-implant contact without substantial marginal bone loss can be accomplished. It is apparent that different modifications have a range of beneficial effects, it is essential to consider at what time point and in what conditions these effects occur. This article reviews existing surface modification technologies of mainstream dental implants and the correlation between implant surface coatings and their performance of osseointegration or anti-bacterial ability it needs to be evaluated.

Resonance Frequency Analysis of Dental Implant Stability During the Healing Period (A Clinical Study)

Aim: The aim of this clinical study was to measure the implant stability quotient using a method called resonance frequency analysis of dental implants during the healing period.
Material and methods: A number of 27 patients received 50 internal hexagon implants (Biohorizons) either in the maxillary or in the mandibular arch. Implant stability was measured with an Osstell Mentor device (Osstel, AB, Sweden) using the resonance frequency analysis at the time of implant placement, 15, 30, 60 and 90 days post insertion.
Results: The mean implant stability quotient for all implants placed was 67.06. The lowest value of the implant stability quotient was at 30 days post insertion measuring 62.
Conclusions: In relation to the gender the implants placed in female patients showed a higher mean value of the implant stability quotient. In relation to the location within the dental arch the implants placed in the anterior areas had a higher implant stability quotient than the ones places in the posterior areas of the arch.
