“…Despite the above-mentioned differences, the cumulative implant survival rate in this study was 97.9%; which is comparable with that of previous studies (Friberg & Jemt, 2010;Jemt, Stenport, & Friberg, 2011;Polizzi et al, 2013;Wennström, Dahlén, Svensson, & Nyman, 1987 Goetz, Duschner, & Wagner, 2008;Ivanoff et al, 2003;Shalabi, Gortemaker, Van't Hof, Jansen, & Creugers, 2006;Shibli et al, 2007;Sul et al, 2001;Xiropaidis et al, 2005) and clinical trials (Arnhart et al, 2013;Jemt et al, 2011;Polizzi et al, 2013;Rocci et al, 2013;Vandeweghe et al, 2016). On the other hand, one should keep in mind the negative impact of surface roughness on plaque formation (Amoroso et al 2006;Bürgers et al, 2010;Quirynen & Bollen, 1995;Teughels et al, 2006).…”

“…compared moderately to minimally rough implant surfaces applied an immediate-loading protocol, and found an enhanced outcome for the moderately rough surfaces (Alsaadi et al, 2008;Arnhart et al, 2013;Jungner, Lundqvist, & Lundgren, 2005;Rocci et al, 2013;Vandeweghe, Ferreira, Vermeersch, Mariën, & De Bruyn, 2016). Glauser, Schüpbach, Gottlow, and Hämmerle (2005) compared both surfaces histologically, and observed a longer junctional epithelium on the minimally rough surfaces versus a wider connective tissue seal around moderately rough implants.…”

“…On the other hand, it is evenly possible that the light scattered from the implant surface can be absorbed by chromophores of the adjacent periodontal tissues, promoting biostimulatory effects (analgesia, anti-inflammation, acceleration of gingival and bone tissue healing, etc.) which have been often reported as a major advantage of laser treatments [18].…”

Diode lasers are widely used in dental laser treatment, but little is known about their thermal effects on different titanium implant surfaces. This is a key issue because already a 10 °C increase over the normal body temperature can induce bone injury and compromise osseo-integration. The present study aimed at evaluating the temperature changes and surface alterations experienced by different titanium surfaces upon irradiation with a λ = 808 nm diode laser with different settings and modalities. Titanium discs with surfaces mimicking different dental implant surfaces including TiUnite and anodized, machined surfaces were laser-irradiated in contact and non-contact mode, and with and without airflow cooling. Settings were 0.5-2.0 W for the continuous wave mode and 10-45 μJ, 20 kHz, 5-20 μs for the pulsed wave mode. The results show that the surface characteristics have a marked influence on temperature changes in response to irradiation. The TiUnite surface, corresponding to the osseous interface of dental implants, was the most susceptible to thermal rise, while the machined surfaces, corresponding to the implant collar, were less affected. In non-contact mode and upon continuous wave emission, the temperature rose above the 50 °C tissue damage threshold. Scanning electron microscopy investigation of surface alterations revealed that laser treatment in contact mode resulted in surface scratches even when no irradiation was performed. These findings indicate that the effects of diode laser irradiation on implant surfaces depend on physical features of the titanium coating and that in order to avoid thermal or physical damage to implant surface the irradiation treatment has to be carefully selected.

“…The popular NobelReplace anodized tapered implant was redesigned to include an internal conical connection with hexagonal interlocking and a built-in platform shift. This design combined with a dedicated drilling protocol provides sufficient primary stability to support immediate provisionalization in many clinical situations [19–21]. …”

ObjectivesThe aim of this multicenter prospective clinical study was to evaluate anodized tapered implants with a conical connection and integrated platform shifting placed in the anterior and premolar maxilla.Materials and methodsThe study enrolled patients requiring single-tooth restorations in healed sites of maxillary anterior and premolar teeth. All implants were immediately temporized. Clinical and radiographic evaluations were conducted at implant insertion, 6 months, and 1 year. Outcome measures included bone remodeling, cumulative survival rate (CSR), success rate, soft-tissue health and esthetics, and patient satisfaction. Bone remodeling and pink esthetic score were analyzed using Wilcoxon signed-rank tests. CSR was calculated using life table analysis. Other soft-tissue outcomes were analyzed using sign tests.ResultsOut of 97 enrolled patients (102 implants), 87 patients (91 implants) completed the 1-year visit. Marginal bone remodeling was −0.85 ± 1.36 mm. After the expected initial bone loss, a mean bone gain of 0.11 ± 1.05 mm was observed between 6 months and 1 year. The CSR was 99.0%, and the cumulative success rate was 97.0%. Partial or full papilla was observed at 30.8% of sites at baseline, 87.2% at 6 months, and 90.5% at 1 year. Soft-tissue response, esthetics, and patient satisfaction all improved during the study period.ConclusionsBone gain was observed following the expected initial bone loss, and soft-tissue outcomes improved suggesting favorable tissue response using anodized tapered conical connection implants.Clinical relevanceRapid stabilization of bone remodeling and robust papilla regeneration indicate favorable tissue healing promoted by the conical connection, platform-shift design.Trial registration clinicaltrials.gov NCT02175550
