“…During the same interval, new bone increased 14-18%, so that the density of total bone increased between 1 and 2 months of healing both at the treated and untreated implants. The increased density of total mineralized bone around implant in the marrow compartment was also shown in an experiment in dogs previously presented [1,34].…”

Background: Altering surface characteristics by increasing its energy and hydrophilicity will accelerate the interaction between cells and implant surface. Energy and hydrophilicity tend to disappear over a short time. The implant surface may be reactivated by the use of argon plasma Objective: To assess bone density at cleaned and activated titanium implants using argon plasma. Methods: Mandibular premolars and first molars were extracted bilaterally in eight Beagle dogs. After three months, four implants, two treated with argon plasma (test; plasma) and two left without treatment (control), were randomly installed in one side of the mandible. Abutments were applied on the implants and a non-submerged healing was allowed. After one month, the same surgical procedures were adopted on the opposite side of the mandible. The animals were euthanized after one month and ground sections representing the healing after 1 and 2 months were obtained for histological examination. Results: No statistically significant differences were found between test and control sites (p < 0.05). After 1 month of healing, new bone was 32.5 ± 12.2% and 33.8 ± 8.8% at the plasma and control sites, respectively. After 2 months, the respective values were 50.8 ± 21.5% and 47.6 ± 15.6%. Conclusion: The treatment of the implant surface with argon plasma did not have a significant effect on bone density around implants.

“…In another experiment in dogs, the early phases of bone formation in the cortical and marrow compartments were studied in submerged implants [34]. In the cortical compartment, new bone density was 0.6%, 2.5%, 16% and 23.3% after 5, 10, 20, and 30 days, respectively.…”

The aim of the experiment was to study the healing at implants installed in site prepared in bone type 1 using different rotation speeds and cooling strategies. The tibiae of twelve sheep were used as experimental sites. Two implant sites were prepared in each tibia using drills either at a high or a mixed speed under irrigation. At the mixed-speed sites, 60 rpm without irrigation were applied for the last drill, the countersink and during implant installation. Biopsies representing the healing after 1, 2, and 6 weeks were obtained and ground sections were prepared. At the histological analyses, after 1 week of healing, no new bone was found at both high- and mixed-speed sites. After 2 weeks of healing, small amounts of newly formed bone were observed in the cortical layer, reaching percentages of 3.6±3.0% at the mixed-speed sites, and of 2.2±1.5% at the high-speed sites. An irrelevant quantity of new bone was seen in the marrow compartments of a few specimens. After 6 weeks of healing, new bone was found in higher quantity, reaching in the cortical compartment 66.9±6.8% and 67.3±17.7% at the mixed- and high-speed sites, respectively. The respective percentages in the marrow compartment were 23.2±13.0% and 30.6±29.2%. No statistically significant differences between high- and mixed-speed groups were found. It was concluded that the use of the last drill and the installation of the implant with or without irrigation yielded similar bone healing and osseointegration.

“…So far, partial bonding was assumed to occur randomly on both cortical and trabecular bone components. Although we do not investigate preferential osseointegration in a specific component (as in eg, 33,34 ), it is nevertheless of interest to consider each bone component separately. Consequently, in this section, the ROA was systematically and randomly varied over the cortical or the trabecular bone interface, while the complementary bone section underwent only frictional interaction without any bonding.…”
