“…In the case of sandblasting materials where hydroxyapatite was also used, following the SEM microscopic analysis presented in Figure 7 to Figure 14, one may observe, that, although Calcium and Phosphorus are clearly identified for both Ti and Ti alloy (Figure 8 and Figure 12), there are as minute traces (Figure 9, 10,13,14).…”

“…The importance of sandblasting resides in its inherent properties and outcome: enhanced surface roughness and increased surface area, essential for mechanical interlocking between the implant, abutment, and restorative material, thorough surface cleanliness, as most of the manufacturing contaminants such as oils, oxides, and residues are removed, increase wettability, effective mechanical retention, due to the increased friction forces [1][2][3][4][5][8][9][10][11][12][13][14][15].…”

“…The surface of the implants used in oral implantology, according to the data provided by the manufacturers, is microtextured obtained by sandblasting and subsequent processing using acids, the formation of the above said morphology being the main cause of microgaps formation at the implant-abutment interface, (IAI), [9][10][11][12].…”

“…Inflammation in the peri-implant tissues is a complication of dental implant treatments which, unlike the tissues around natural teeth, starts much easier, evolves faster and is more resistant to treatment. To prevent this inflammation, all the risk factors involved must be identified and eliminated [7,8,10].…”

Sandblasting materials used for dental restoration is a valuable preconditioning technique enhancing the physical properties and promotes osseointegration and cell adhesion. Ti medical grade 4 and Ti6Al4V were blasted with a series of various naturally occurring and synthetically produced spraying materials of controlled granulometry, at precise spraying duration and spraying pressure, and the results were analyzed in terms of the obtained surface roughness and by SEM analysis. It was found that in all cases, regardless of the spraying material or working conditions, the roughness profile achieved is a uniformly distributed one. A reduction in the blasting pressure by half led to a decrease in the roughness between 30 and 35%. The use of glass balls as blasting material led to decreased roughness and a more uniformly distributed roughness values for Ti as well as for Ti6Al4V regardless of spraying duration or applied pressure comparing to other spraying materials, and blasting with olivine led to increased, as well as uniformly distributed values, and hence the conclusion that one may control the roughness size by choosing one or another from the above materials, without the need of changing any other operating parameters. In the case of Ti, the achieved roughness is greater than in the case of Ti4Al6V, irrelevant of the blasting material, the differences being smaller the softer the sandblasting material due to the fact that Ti alloys have better mechanical properties and increased hardness comparing to pure Ti. SEM analysis showed that the use of sintered hydroxyapatite as an additive to the blasting material does not necessarily lead to a substantial deposition of hydroxyapatite on the substrate materials, only traces of it being identified during the analysis.

Sandblasting materials used for dental restoration are a valuable preconditioning technique that enhances the physical properties and promotes osseointegration and cell adhesion. Triplicate groups of Ti medical grade 4 and Ti6Al4V were blasted with 16 series of various naturally occurring and synthetically produced spraying materials of controlled granulometry at three spraying durations each and two spraying pressures, and the results were tested for the determination of the surface roughness taken as an average of 80 points ±5 points for each particular series of operating parameters. SEM analysis and specific tests to see whether or not cell cultures proliferate on the treated materials were also conducted. It was found that in all cases, regardless of the spraying material or working conditions, the roughness profile achieved is a uniformly distributed one. A reduction in the blasting pressure by half led to a decrease in the roughness between 30 and 35%. The use of glass balls as blasting material led to decreased roughness and more uniformly distributed roughness values for Ti as well as for Ti6Al4V, regardless of spraying duration or applied pressure compared to other spraying materials. Blasting with olivine led to increased, as well as uniformly distributed, values, and hence the conclusion that one may control the roughness size by choosing one or another of the above materials without the need to change any other operating parameters. In the case of Ti, the achieved roughness is greater than in the case of Ti4Al6V, regardless of the blasting material; the differences are smaller the softer the sandblasting material due to the fact that Ti alloys have better mechanical properties and increased hardness compared to pure Ti. SEM analysis showed that the use of sintered hydroxyapatite as an additive to the blasting material does not necessarily lead to a substantial deposition of hydroxyapatite on the substrate materials; only traces of it were identified during the analysis. As a general conclusion, this study showed that by sandblasting Ti and Ti6Al4V with different spraying materials, one may control the surface roughness, and this technique may be an attractive method for preconditioning these materials for restorative dentistry.
