“…Consequently, the correlations found were very high. The minipig intra-oral model is known to represent a fully functional in-vivo anatomical model for dental implant placement and it has been increasingly used to assess the performance of dental implants [15,27,28]. In this study the encountered bone was rather dense and only 29 out of 134 osteotomies and implants were included in the analysis.…”

When preparing an implant site, clinicians often base their assessment of the bone on subjective tactile and visual cues. This assessment is used to plan the surgical procedure for site preparation, including how many drilling steps will be used. The subjective nature of bone evaluation, consequently, results in poor reproducibility and may lead to under or over preparation of the site. Recently, an unconventional site preparation protocol was developed in which the decision of which instruments to use is dictated by insertion torque of the novel site preparation instrument (OsseoShaper ™ , Nobel Biocare AB, Gothenburg, Sweden). The aim of this study was to quantify the correlation of the site preparation torques of the new instrument with bone density and maximum implant insertion torques. In vitro and in vivo data showed strong linear correlation between site preparation torque and density and resulted in reliable implant insertion torques, respectively. From our analysis, we conclude that this new instrument and protocol has the potential to eliminate the need for additional intraoperative bone evaluation and may reduce the risk of inadequate preparation of the site due to the ability to serve as a predictor of the final implant insertion torque.profile combined with a cutting flute and unconventional site preparation protocol. Following the pilot drill, the osteotomy is shaped with an implant-specific single use instrument, OsseoShaper1 (OS1), without irrigation at low speed (25-100 rpm) using a motorized drill unit with a maximum torque setting of 40 Ncm (Figure 1). The OS1 torque, measured by a drill unit with real-time torque display, determines the workflow for implant placement. If the OS1 achieves the desired depth and position with less than 40 Ncm, the implant can be placed. If the OS1 torque reaches 40 Ncm before it reaches the planned position, the next instrument should be used to further shape the implant site.

“…Surface modification can enhance bone healing and integration of titanium implants and result in higher bone-implant contact ratios [20, 31]; however, the interfacial interaction of modified zirconia with bone is still not fully understood. A number of animal studies have been published that outline hard and soft tissue integration of zirconia implants on the histological level and have shown promising results [29, 32, 33]. Further, cell culture studies have demonstrated that zirconia especially with a moderately rough surface is accepted by osteoblasts and integrates into bone tissue [9, 34].…”

“…By far, histomorphometric analysis has been the gold standard in evaluating the bone-implant interface. The various methods of the histomorphometric analysis, microscopic magnification, and different software and algorithms appear to play a crucial role in BIC calculations which may subsequently lead to deviant results [29, 32]. The bone tissue has to be transferred to specialized laboratory for preparation immediately after animal sacrifice.…”

“…Pigs and rabbit were commonly used as experimental models in accepted studies, while monkey and rat were used in two studies. Variation in animal models among studies may result in considerable variations in the results [32]. Selection of an appropriate animal model for demonstrating the response of bone tissue to biomaterial is difficult, mainly because the bone characteristics, microstructure, composition, modeling, and remodeling are different from those of humans [40].…”

Background. The information available about osseointegration and the bone to implant interaction of zirconia implants with various surface modifications is still far from sufficient. Objective. The purpose of this systematic review and meta-analysis was to evaluate and compare zirconia dental implants with different surface topographies, with a focus on bone to implant contact and removal torque. Methods. The systematic review of the extracted publications was performed to compare the bone to implant contact (BIC) with removal torque (RT) values of titanium dental implants and machined and surfaced modified zirconia implants. Results. A total of fifteen articles on BIC and RT values were included in the quantitative analysis. No significant difference in the BIC values was observed between titanium and machined zirconia implants (p = 0.373; 95% CI: −0.166 to 0.443). However, a significantly better BIC values were observed for acid etched zirconia implants compared with those of titanium implants (p = 0.032; 95% CI: 0.068 to 1.461). Unmodified zirconia implants showed favorable BIC values compared to modified-surface zirconia implants (p = 0.021; 95% CI: −0.973 to −0.080). Conclusion. Acid etched zirconia implants may serve as a possible substitute for successful osseointegration.

“…Osseointegration has been established as a healing period that involves cellular and extracellular events and is characterized by the creation of structural and functional connections between the bone and the surface of the implant. 1,13,33 Different methodologies have been developed to evaluate the interaction between the bone and the implant surface. 13,34 In this way, osseointegrations of M-Y-TZP, M-Ti and RBM-Ti were evaluated by micro-CT, histomorphometry and fluorochrome labeling analyses.…”
