“…There is no reliable information about other surface micro-factors being important for osseointegration -the order of irregularities seems irrelevant (anisotropy or isotropy; Gö ranson et al, 10 ); the precise way to manufacture irregularities seems irrelevant (each company seems to prefer their own method) and good clinical results have been reported for many modern implant systems. [11][12][13][14][15] There is a substantial problem in evaluating effects of changing the nano-topography of an implant; if surface changes are performed at the nanometer resolution level, there will be simultaneous alterations of the micro-roughness, hence it is difficult to evaluate …”

The osseointegrated interface demonstrates, on an average, some 60-70 per cent bone bordering the implant at the light microscopical level of resolution whereas ultrastructural studies have revealed that only partly calcified proteoglycan layers build up the actual interface. Interfacial bone reactions are dependent on the precise nature of the implant material, its design and surface characteristics supposing that clinical factors such as host reactions and surgical and prosthodontic techniques are being controlled. The most commonly used, although not the only useful, material in oral implantology is cp titanium, a most biocompatible material. The most commonly used oral implant design is the threaded screw whereas cylindrical implants without retention elements have been largely abandoned. The nature of the implant surface is of clear relevance for interfacial reactions; micron-sized irregularities are necessary for osseointegration or biomechanical bonding. Currently, there is evidence of bone ingrowth dependent on nanometer sized irregularities, even if the clinical relevance of this finding remains uncertain. The discussion about an alternative type of implant anchorage (biochemical bonding), started decades ago, however so far without any undisputable evidence of its importance for the oral implant anchorage. Lately, the long-term stability of the oral implant interface has been questioned by some investigators, allegedly it would be threatened by an increasing occurrence of peri-implantitis, however in reality demonstrated for only about 2 per cent of implants over a 10-20 year follow-up.

“…The realization that implants made of commercially pure titanium attain direct bone to implant contact initiated this revolution in oral rehabilitation. This phenomenon of osseointegration (or functional ankylosis) was first described by Brå nemark et al 1 and Schroeder et al 2 There have been numerous studies published evaluating clinical outcomes of implants placed in institutional settings, [3][4][5][6][7][8][9] but there are few references relating to implants placed and restored in private practice settings. [10][11][12] The aim of this retrospective study was to analyse the clinical parameters involved in the planning, placement, survival and success of 1000 consecutively placed Straumann (formerly ITI) implants in a private specialist periodontal practice.…”

Background: There have been numerous reports evaluating clinical outcomes of implants placed in institutional settings, but there are few studies relating to implants placed in private practice. The aim of this retrospective study was to analyse the clinical outcomes of 1000 consecutively placed Straumann implants in private specialist periodontal practice. Methods: A hand-search of patient records was undertaken to identify 1000 consecutively placed implants. Data extracted included patient demographics, details of implants placed, implant sites, timing of placement after extraction, hard and soft tissue augmentation procedures, loading protocols, type of prostheses and treatment outcomes (implant survival, implant success and complications). Results: The majority of implants (71.5 per cent) placed in patients aged 40 to 69, and the majority of patients (88.6 per cent) received 1 or 2 implants. During the period of the study, 9 implants were lost and 45 presented with complications requiring chairside intervention. A life table analysis showed 5 and 10-year cumulative survival rates of 99.2 per cent and 98.4 per cent respectively, and 5 and 10-year cumulative success rates of 93.1 per cent and 90.9 per cent respectively. Conclusions: With careful treatment planning and adherence to recommended surgical and prosthetic protocols, high implant survival and success rates can be achieved in a private practice setting.

“…Other experimental studies confirmed the increase in BIC for titanium grit-blasted surfaces 12,29 . Other studies have reported high clinical success rates for titanium grit-blasted implants, up to 10 years after implantation 30,31 . Comparative clinical studies gave higher marginal bone levels and survival rates for TiO2 grit-blasted implants than for machined turned implants 32,33 .…”
