(20) This is located by inserting the needle at a point one quarter of the distance from the ischial tuberosity to the greater trochanter in the gluteal fold and then feeling two distinct losses of resistance as superficial and deep fascia are penetrated with a short-bevelled needle.
Chamfering
Definition:
(p. pr. & vb. n.) of Chamfer
Example Sentences:
(1) Somehow, everything we produced had a decidedly 1970s feel, a look formed by both the number of chamfered blocks in the set, and the inescapable desire to make everything symmetrical as you stack floor upon floor.
(2) Although the dentin bonding agents tend to accumulate on chamfers, thereby increasing their thickness to 200-300 microns, the method looks promising as a simple way to protect the pulp from the consequences of microleakage.
(3) A chamfer with a bevel, a shoulder with a bevel, or chamfer preparations are not suited to this technique.
(4) The crown margin designs taught most often were the flat shoulder, the 45-degree bevel shoulder, and the chamfer.
(5) This study evaluated chamfered and beveled preparations for Class IV restorations of lesions with microfilled and macrofilled composite resin.
(6) Serial radiographic analyses demonstrate progressive narrowing of all of the chamfered cylinder design and less in hemispherical design with screw fixation.
(7) This study tested three different types of crown margin preparations--a chamfer, a shoulder, and a shoulder plus a bevel to determine whether or not the margin preparation could affect microleakage.
(8) Facial and lingual chamfer margins were placed in enamel, mesial and distal in dentin and cementum, and castings were made in Rexillium III alloy and were then cemented with a standardized technique.
(9) This study indicated that the resin bonded cast fixed partial denture with the lingual chamfer margin and mesial rest was the design to be chosen.
(10) Group I consisted of 43 restorations placed without any tooth preparation; Group II consisted of 72 restorations placed using a chamfer preparation.
(11) The margin designs were rounded-shoulder, rounded-shoulder with a bevel, and a chamfer.
(12) On the acetabular side, both the cementless hemispherical with screw-type adjuvant fixation, or the chamfered cylinder designs, used primarily with the UCLA porous surface replacements, but also with stem-type devices, appear to achieve best short-term results, while the entire variety of screw rings are disappointing.
(13) With 76 different types of Lego bricks scattered across the table, from flat baseplates to chamfered wedge-shaped blocks and lots of tiny pieces with nipples and sockets sprouting in all directions, the challenge was to know where to begin.
