How is implantation of an artificial tooth carried out?


How is implantation of an artificial tooth carried out?

These days many patients suffering from dental disorder prefer implantation for replacing a tooth which needs to be removed because of decay or is lost otherwise.The procedure is simple and requires only a few sittings. In most cases, it is the diseased tooth which needs to be replaced. The tooth is extracted under local anaesthesia and implantation bed is surgically placed in the jawbone.

The implant, which actually is an artificial tooth root made of titanium with a suitable crown set on top of it,is screwed into the jawbone. (See diagram). This method of tooth replacement has many advantages over a dental bridge. The adjacent teeth need not be reshaped as with a bridge, an implant has greater durability, and it can bear stresses just as a natural tooth can. The downside is that the implant is rather expensive and may set one back by Rs. 25,000 or so. Besides, an implant is a no-no in case of those people who have osteoporosis, i.e. low mineral bone density. The implant would not only lack sound foundation,but it may also cause fracture in the porous and fragile jawbone.

What is the mystery in coarse Velcro strip used for fastening the straps of sports shoes, briefcases, wallets, belts, jerkins etc.? To start with read about an interesting incident: It was the year of 1948. On one early afternoon a researcher named George Dimistral was strolling with his dog in the countryside of Switzerland. He unleashed the dog to let it roam about in the countryside while he strolled. When they returned home Dimistral found strands of some wild flowers stuck all over the dog's furry body. He tried to pull the strands out of the dog's hair but did not find it easy. They held fast in the hair and required some force to pull them out. George Dimistral being a researcher to the core got interested in this mystery and examined some strands under a microscope. He found that the ends of those strands were like hooks. Once the dog's hairs were hooked they remained hooked fast.

What is wasp nest made of?

        An English naturalist named Roger Harvey was collecting samples of leaves to study the vegetation during his visit to Africa in the mid 20th century. After walking miles for the samples, he sat down on a stone to rest his tired limbs. About 10 feet away from where he was resting he saw a wasp working furiously in the sandy soil. Roger Harvey had some knowledge about insects, so he made no mistake in recognizing the insect for a wasp. (Otherwise most people confuse a wasp with a honey bee, since at first glance the appearance of both the insects is more or less similar). Harvey got interested in the activities of the wasp. As he looked on, this wasp moved grains of sand with its fore legs and filling up a hole. Just as a pirate works at a feverish pace to bury his looted treasure, so also the wasp was working at an extremely fast pace to seal the hole. After sometime, the hole was sealed up; but the wasps was not satisfied. It pulled and piled up a small
