Southern Implants has been a pioneer in the top-end specialist sector of the dental implant market since 1987, servicing maxillofacial and craniofacial surgeons, prosthodontists, periodontists and general dental practitioners alike.
The Southern enhanced surface is not a “coating”, it is an abraded rough surface of Rutile Titanium. This is the same dense form of titanium common to “machined” surface implants. (the anodic oxidation surfaces are not Rutile Titanium; they are a mixture of anatase and amorphous titanium which are less dense and softer forms of titanium).
A. The first experimentation with this Southern Enhanced surface was in 1992. After extensive validation it was put into widespread clinical use in 1997. It is achieved by a subtractive process in which specifically sized and shaped, sharp cornered, Alumina particles (A 1203) are blasted with decontaminated air onto the implant surface with controlled pressure, displacement and time.
B. The particle size of 11 Oμm is supported by the work of Soskalne (Israel) and Wennerberg (Sweden) on the one hand and Ronald (Norway) on the other. Based on their research, greatest bone to titanium bond strength is obtained with abrasion particles greaterthat 75μm and less than 170μm.
C. Szmukler-Moncler has analyzed and compared the popular implant surfaces in publications and a presentation at the AO, San Francisco 2004. He reports that the Southern Surface is remarkably consistent and free of contaminants whilst those that are acid etched or oxidized are shown to be highly variable.
D. There seems to be consensus in the literature that “moderately rough” surfaces pose no risks for the patient and are therefore safe to use. Moderately rough was defined by Albrektsson as Sa 1.0 to 2.0μm (applied Osseointegration Research Vol 5, 2006). The Southern surface has s. = 1.43 in one published study and Sa= 1.55 on implants analyzed by Prof Ann Wennerberg in 2006. Dr Mats Wikstrom, Chief of Clinics, Branemark Centre Goteborg, in 2007 concluded that the Southern surface is one of the three best documented moderately rough surfaces on the market.
The Oral lmplantology Research Group, University of Otago, conducted Randomized Clinical Trials (RCTs) involving Southern Implants rough surface. These Studies have gone in excess of 10 years in both mandibles and maxillas. The 8 year and 5 year results are published in Cochrane Collaboration reports. Standardized radiographs show marginal bone loss of all the implants to be well within the criteria set by Albrektsson & Zarb (1993, 1998) as well as Fourmousis & Bragger (1999). In conclusion, it is a well documented surface with a consistent manufacturing process.
