An evaluation of superhydrophilic surfaces of dental implants - a systematic review and meta-analysis.

BACKGROUND: The characteristics of a dental implant surface have a decisive influence on the process of osseointegration. According to the current state of knowledge, surface modification can not only affect the morphology of cells, and in this way have a positive impact on osseointegration. METHODS: The objective of this study was to compare survival rates and marginal bone loss as well as assess the degree of stability of Straumann SLAactive® and Thomenn Incell® implants with a superhydrophilic surface. Authors present review of data published between 01.01.2008 and 12.31.2016 that was found in PubMed/MEDLINE internet database, An Internet search of databases produced a total of 1230 studies, 20 publications were finally selected for the present study based on the established selection and exclusion criteria. RESULTS: The statistical analysis was performed. A Cumulative Implant Survival Rate (CSR%) was 98.5%, Marginal bone loss (MBL) after 6 months was M = 0.60 mm and 0.6 5 mm after 12 months and secondary stability in a group Thommen implants M = 71.3 ISQ and M = 75.2 ISQ in group of Straumann. CONCLUSION: Despite certain differences in the values of the studied parameters, both of the systems, i.e. Thommen Inicell and Straumann SLActive, demonstrated a high survival rate, a high level of implant stability and low marginal bone loss.

A comparative study of the effectiveness of early and delayed loading of short tissue-level dental implants with hydrophilic surfaces placed in the posterior section of the mandible-A preliminary study.

The objective of the present study was to compare the primary and secondary stability of tissue-level short dental titanium implants with polished necks and hydrophilic surfaces of two different designs and manufacturers. The first implant system used (SPI®ELEMENT RC INICELL titanium implants, Thommen Medical AG, Grenchen, Switzerland), allowed functional loading 6 weeks after its placement, whereas the second implant system (RN SLActiv® tissue-level titanium implants, Straumann GmbH, Fribourg, Germany), was loaded after 15 weeks. The degree of primary and secondary stability was determined using an Osstell ISQ measuring device. Marginal bone loss (MBL) was evaluated radiographically 12 and 24 weeks after implantation and the Wachtel's healing index as well as the patient's satisfaction with the treatment was registered on a VAS scale. The intergroup comparison revealed significant differences in terms of primary stability as well as differences in MBL 3 months after the procedure, but no significant differences could be found after 6 months and for secondary stability. The primary stability was significantly higher for Thommen® compared to Straumann® implants. Insertion of short dental implants with a hydrophilic conditioned surface significantly shortens patient treatment time.
