Effect of Different Sandblasting Procedures on the Surface Roughness of Zirconia Ceramic

Munir Tolga Yucel, Yener Okutan

The aim of this study was to evaluate the surface roughness of a monolithic zirconia ceramic with different sandblasting procedures. 70 ceramic specimens were prepared from monolithic zirconia block (Zenostar T) and divided into 7 groups for different sandblasting procedures. The surface roughness was measured and data were statistically analyzed by 1-way ANOVA and Tukey’s HSD tests. Control group showed statistically lower Ra values compared to others (p<0.05). Higher Ra values were measured in 4 bar groups compared to 2,5 bar groups (p<0.05). The pressure of air-abrasion was found to be an effective factor to increase surface roughness.

Effect of air-abrasion distance on surface roughness of CAD/CAM composite material

Yener Okutan

The aim of this study was to investigate the effect of air-abrasion distance on the surface roughness of a CAD/CAM composite material. A total of 70 specimens were cut from reinforced composite CAD/CAM block (Brilliant Crios). The surfaces were ground using silicon-carbide abrasive papers. Specimens were divided to 7 groups according to air-abrasion distances. Air-abrasion was performed using 50 µm aluminum-oxide particles under 1.5 bar from 5, 10, 15, 20, 25 and 30 mm distances. Surface roughness (Ra) values were measured using a profilometer. Data were statistically analyzed by ANOVA and Tukey’s HSD tests. The highest Ra values were found at 5 mm group (1.57±0.10 µm) whereas control group showed the lowest Ra values (0.48±0.08 µm). 10 mm group showed higher Ra values than 20, 25 and 30 mm groups (p<0.05). Reduced air-particle abrasion distance might be used in order to obtain rougher composite surfaces.

Приноса на ортодонтите в лечебното планиране на пациенти с вродена липса на зъби

Pr.Olga-Elpis Kolokitha

Patients with congenitally missing permanent teeth seeking treatment present with unesthetic diastemas, midline deviation and tilting of adjacent teeth in the edentulous areas. The impact of tooth agenesis reflects on esthetics, function, psychological and social well-being of the individuals affected. Orthodontics can contribute to the treatment plan selected by rearranging the present teeth so as to open spaces for prosthetic restorations or close spaces followed by reshaping teeth by the dentist. Whatever the treatment option is, the interdisciplinary approach involving orthodontics, esthetic dentistry, implantology and prosthodontics can achieve an optimal occlusion and a well-balanced and natural smile overtime.
