In the medical language in dental science the crown of the teeth is the outer layer of the teeth teeth,covered by enamel the very hard material. When it is damaged or chipped/broken then the dentists apply the artificial crown made up of gold or silver.
which number of teeth is consider is crown!
only one number
,(crown)
Why are the occlusal surfaces and crown height of the posterior dentition considered to be two important ways of classifying teeth? Be specific.
2. Why is it important to pump the setting acrylic crown on and off of the tooth? A. O To prevent it from locking onto the teeth B. O To prevent overheating the teeth and gingiva C. To prevent burning the gingiva D. All of these reasons
2. An animal is considered if it has two sets of teeth. A. duodont B. bidont O C. diphyodont OD. deciduodont
1. A commercial straight pinion has an 8 teeth / in. Diametric pitch, a 1.5 in. Face width, 16 teeth and a 20 pressure angle with full height teeth (calculating the Kx speed maker considering a milled profile). To be mated with a 50-tooth crown made of cast iron ASTM No. 50. With a tangential load of 382 lbf, estimate the safety factor of the transmission, based on the possibility of fatigue failure on the surface.
write why following properties needs to be considered while making molar teeth: bodily response, youngs modulus, fracture toughness, yield strength, density, and thermal conductivity. write one, two sentences for each of these properties important for molar teeth. please also tell whether material with high density, thermal conductivity is good for molar teeth. or not? why?
6. Compared with the size of their well-developed roots, these teeth have a relatively small, distinct crown. A. Elodont B. Brachyodont C. Deciduous D. Hypsodont
A commercial straight pinion has an 8 teeth / in. Diametric pitch, a 1.5 in. Face width, 16 teeth and a 20 ° pressure angle with full height teeth (calculating the Kv speed maker considering a milled profile). To be mated with a 50-tooth crown made of cast iron ASTM No. 50. With a tangential load of 382 lbf, estimate the safety factor of the transmission, based on the possibility of fatigue failure on the surface. (EP = 30Mpsi, vP...
A speed reducer has 20° full-depth teeth with a diametral pitch of 4 teeth/in, a face width of 3.25 inches, and with the pinion having 22 teeth and the gear having 60 teeth. The pinion is driven by a 40 HP motor rotating with a shaft speed of 1145 rpm. The pinion is designed to last for 5 years operating around the clock. The gears are manufactured using 4340 through-hardened grade 1 steel, both heat treated to 250 HB using...
