Setting time of different dental stones depends on factors such as water-powder ratio, time and speed of spatulation
, temperature of water and environment, composition of water and powder, humidity of environment and the colloidal system.
Classical steps for pyeloplasty were then performed: spatulation
of the ureter, introduction of a 6 Ch 26 cm double-J stent in an antegrade fashion down the ureter into the bladder (passed along a 0.
Wallace 2 technique ('head-totail anastomosis'): After spatulation
, the distal ureteric margin is anastomosed to apex of spatulated contralateral ureter.
NY, USA) were taken with a pH meter at 1, 3, 5,15, and 30 min; 1, 2, 3, 4, 6, 9, 12, 24, 48, and 72 h; and 4, 6, 7, 15, and 30 days after spatulation
Impression materials can be mixed manually, via hand spatulation
, or automatically, by using a hand--powered impression gun or an automated mixing machine (Figure 3, left).
This may require a ventral incision and spatulation
of a neomeatus to allow for voiding and decrease the risk of meatal stenosis.
This flap is used for ureteral handling (a "no touch" technique) during pyeloplasty and also serves as a very reliable guide for lateral ureteral spatulation
, preventing ureteral twisting and subsequent misalignment of the de novo ureteropelvic junction.
New York, NY, USA) with a pH meter at 3, 24, 72, and 168 h of spatulation
of the resulting paste before adding diluent further aids in the dispersion process.
Composite pastes made up of various resins (Table 4; mass fraction 60%) and ACP fillers (Table 5; mass fraction 40%) were formulated by hand spatulation
provides a good calibre of urethra for better anastomosis.
The powder is white and its coarse particles were distinguished during spatulation
