Abstract

Purpose

The purpose of this study was to investigate the quality of final impressions and prescriptions for fixed restorations that were received by private and educational institute's laboratories in Sudan.

Materials and methods

Two hundred and seventeen questionnaires were distributed to eight private laboratories and seven dental schools in Sudan. The questionnaires were filled by the dental technicians and who were trained and instructed to complete one questionnaire per one final impression for fixed restoration immediately after it was received.

Results

Total response rate was 87%; the responding technicians had found evidence of obvious contamination in 23.8% of the examined impressions; blood was clear in 68.9% of these cases. Metal stock trays were used in 57.1% of the examined sample. About two-third of the impressions had been taken using condensation silicone (64.6%). Poor or no written instructions were observed in half of the sample (n = 103).

Conclusion

According to results of this study there was widespread use of inappropriate impression materials; the cross-infection control of sent impressions was below standard and there were poor prescriptions and communications with laboratory technicians in Sudan.

Flexure Strength and Fatigue Durability of Ce-TZP/Al2O3 Nanocomposite with Different Sintering Process and Surface Treatment

[Year:2013] [Month:July-September] [Volume:3] [Number:3] [Pages:4] [Pages No:92 - 95]

Abstract

Purpose

Ce-TZP/Al2O3 nanocomposite (NANOZR) has not only higher strength, but also higher fracture toughness than conventional Y-TZP. NANOZR is generally machined from densely sintered block. However, it is more efficient to sinter densely after machining partially sintered block, if the mechanical strength of final product is enough. Moreover, as for NANOZR, it has been reported that mechanical strength changes with surface treatments. The purpose of this study is to evaluate the effect of sintering process and surface treatment on biaxial flexure strength and fatigue durability of NANOZR.

Material and methods

Two kinds of NANOZR specimens were prepared (Pre-sinter and Full-sinter). Pre-sinter and Full-sinter were given machine polish (MP) or shot-blast and fluoric acid etching (SB + HF). Biaxial flexure strength was measured as recommended by ISO 6872. The cyclic loading test of the load equivalent to 480 MPa was performed by the application of a cyclic load in the bending mode at a frequency of 10 Hz, for 106 cycles in distilled water at 37°C.

Results

Biaxial flexure strength of MP was 1244 ± 43 MPa and 1320 ± 50 MPa in Pre-sinter and Full-sinter, respectively. and it of SB + HF was 1070 ± 60 MPa and 1069 ± 12 MPa in Pre-sinter and Full-sinter, respectively. In the cyclic fatigue test, the durability over the 106 cycle load equivalent to 480 MPa was shown on all the conditions.

Conclusion

Even if NANOZR was densely sintered after machining partially sintered block, having satisfactory biaxial flexure strength and fatigue durability on clinical application as dental prosthetic material was shown.
