“…Many studies have reported that the bone–implant interface can influence peri-implant bone healing and the osseointegration process [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 ]. Not only does a rough implant surface ensure an improved bone anchorage when compared to a smooth implant surface, but it also promotes mesenchymal cell differentiation toward an osteoblastic phenotype [ 11 ].…”

Effect of Different Surface Treatments on Titanium Dental Implant Micro-Morphology

Background: Titanium dental implants are today widely used with osseointegration mainly dependently on the implant surface properties. Different processing routes lead to different surface characteristics resulting, of course, in different in situ behaviors of the implants. Materials: The effect of different treatments, whether mechanical or chemical, on the surface morphology of titanium implants were investigated. To this aim, various experimental methods, including roughness analysis as well scanning electron microscope (SEM) observations, were applied. Results: The results showed that, in contrast to the mechanical treatments, the chemical ones gave rise to a more irregular surface. SEM observations suggested that where commercial pure titanium was used, the chemical treatments provided implant surfaces without contaminations. In contrast, sandblasted implants could cause potential risks of surface contamination because of the presence of blasting particles remnants. Conclusions: The examined implant surfaces showed different roughness levels in relation to the superficial treatment applied. The acid-etched surfaces were characterized by the presence of deeper valleys and higher peaks than the sandblasted surfaces. For this reason, acid-etched surfaces can be more easily damaged by the stress produced by the peri-implant bone during surgical implant placement.

“…Osseointegration is defined as ''a direct structural and functional connection between ordered, living bone and the surface of a load carrying implant'' [3]. Successful osseointegration is considered to be a significant prerequisite for functional dental implants [3,4]. Implant stability is considered to be a reliable predictor for successful osseointegration in many studies and thus the measurement of stability can serve as a dependable method for the evaluation of osseointegration [3][4][5][6][7][8]23].…”

“…Dental implants have become a definitive method for the esthetic and functional rehabilitation of both partially and completely edentulous arch [1,2]. Although studies have shown high survival rates of dental implants, there are many cases of implant failures reported every year owing to either peri-implant tissue infections or failure of the implant to successfully integrate to the surrounding bone [1][2][3][4][5][6][7][8]. These failures are seen to be distributed unevenly among general population and tend to occur in some individuals particularly even when optimal materials are used and surgical protocols are strictly followed [1,2,4,[9][10][11].…”

Purpose Dental implants have become a definitive method for the esthetic and functional rehabilitation of both partially and completely edentulous arch. There is a significant role of vitamin D in bone metabolism and there are only few human studies that evaluate the effect of vitamin D deficiency on stability of dental implants. The study thus aims to evaluate the correlation of vitamin D deficiency and implant stability in delayed endosseous implant. Methods The study included 20 subjects of either gender in the age group of 20-50 years, who required implant placement for rehabilitation of partially edentulous condition. Vitamin D status was evaluated for all subjects preoperatively. Implant stability was checked postoperatively at three months and six months using Electronic Technology Resonance Frequency Analysis. ResultsThe study found that for every 1 ng/ml increase in Vitamin D levels, the implant stability Quotient value (ISQ) significantly increased by 0.48 at 3 months and 0.62 units at 6 months, which was statistically significant at P = 0.01 and P = 0.002, respectively. Statistical analysis was done using Student Paired t test, Pearson Correlation test and Simple Linear regression analysis. Conclusion Albeit the smaller sample size, the results of the study showed the positive influence of vitamin D on stability of implant. The study thus emphasizes on the significance of screening the vitamin D status of subjects prior to implant placement.

“…Therefore, less invasive methods [9,10] have been proposed to assess the stability of microimplants. One of these methods [11,12] involves the Periotest M (Medzintechnik Gulden, Modautal, Germany), which has been used successfully. This study used the Periotest value (PTV) to determine the primary stability of the microimplants.…”

Effect of Microimplant Neck Design with and without Microthread on Pullout Strength and Destruction Volume

et al. 2021

The microthread neck concept has been applied to dental implants. This study investigated the pullout strength and destruction volume of orthodontic microimplants with and without the microthread neck design. Fifteen microimplants (diameter: 1.5 × 10 mm) of three types (Types A and B: without microimplant neck; Type C: with microimplant neck) were tested. The insertion torque (IT), Periotest value (PTV), horizontal pullout strength (HPS), and horizontal destruction volume (HDV) of each type were measured. Kruskal–Wallis H test and Dunn’s post-hoc comparison test were performed to compare the measured values of the three types of microimplants. The correlations of the measured values were used to perform the Spearman’s correlation coefficient analysis. The ITs of Types B (8.8 Ncm) and C (8.9 Ncm) were significantly higher than those of Type A (5.2 Ncm). Type B yielded the lowest PTV (4.1), and no statistical differences in PTV were observed among the three types. Type A had a significantly lower HPS (158.8 Ncm) than Types B (226.9 Ncm) and C (212.8 Ncm). The three types did not exhibit any significant differences in the HDV. The results of the Spearman’s correlation coefficient test revealed that HDV (ρ = 0.710) and IT (ρ = 0.813) were strongly correlated with HPS, whereas for PTV and HPS, it was not. HPS was strongly and significantly correlated with HDV. The orthodontic microimplant with a microimplant neck design did not perform better than that without a microthread in the mechanical strength test.
