The integration of an implant into the bone tissue is a key success factor for the replacement of missing teeth and the long-term success of the rehabilitation. For many years, Ardentis Dental Clinics has contributed to clinical studies aimed at improving the process of implant osseointegration.
It is well established that modifications to the surface of titanium implants—such as acid-etching and sandblasting—significantly affect early biofilm formation. In parallel with research on osseointegration, Ardentis has also focused on optimizing the adhesion of gingival soft tissues to the implant collar, as this can influence the risk of developing peri-implant inflammatory responses.
A multicenter study involving Ardentis, the University of Geneva, the University of Bern, and a private practice (Langenthal, Switzerland) was conducted over three years. The aim was to evaluate and compare soft tissue changes around implants with a hydrophilic, sandblasted, and acid-etched collar versus control implants with a machined collar (titanium-zirconium implants, Straumann AG, Switzerland).
Thirty-eight patients received implants at random and were followed over the course of the study. After three years, 98% of the implants remained in place. However, implants with a sandblasted and acid-etched collar did not demonstrate clinical or radiographic advantages compared to implants with a machined collar.
The study was published in the international journal Journal of Clinical Periodontology (impact factor*: 4.164):

Ardentis Dental Clinics collaborates with Straumann AG on the optimization of implant surfaces and the placement of implants in specific indications. Technological improvements and the application of innovations are essential to treatment success at Ardentis.
* An impact factor is the average number of citations per article published in a scientific journal. It is an indirect indicator of the journal’s visibility.
