Yes.  Maxillary is the upper arch and mandibular is the lower arch.

I'm a dentist.\n\nAttrition, my good friend.  Attrition.\n\nAs we age, our teeth tend to wear a little, but just a little.  Not enough to significantly alter the shape of any tooth.\n\nDid you know that the only time that our upper teeth and lower teeth should come into contact with each other is when we swallow?  Other than that, they should never touch.  Not when chewing your food.  Not when talking.  And certainly not at rest.  This is a fact.  The key words here, however, are "should never".  Unfortunately for most people, they touch much more frequently.\n\nWhat really changes the shape of our teeth is wear against the opposing teeth.  Many people grind their teeth or have some sort of habits that involve touching teeth together.\n\nAdditionally, dental work (with the exception of metallic materials) wears away the opposing teeth more quickly.  Porcelain crowns are notorious for causing excessive wear on teeth opposing them, as porcelain is much more abrasive than enamel.\n\nCanine teeth, both upper and lower (but especially the upper) serve an extremely important job in the mouth, and it is why any good dentist would make every last effort to save a canine tooth rather than extract it.  To explain this, I have to give you a little info about our masticatory system.  We have various muscles that close our jaws: masseter, temporalis, and medial pterygoids, all of which are controlled by the mandibular branch of the trigeminal nerve (Cranial nerve 5).  This nerve originates in our brainstem, if memory serves.\n\nTeeth do not sit directly in bone.  They are suspended by the periodontal ligament (PDL for short), which has many nerves in it, some of which are pressure sensors that tell your brain how much pressure is being applied to the teeth.  That's how you know to chew hard on beef jerky and softly on ice cream.  When your molars' PDLs pressure receptors are stimulated, your brain knows that it is ok to provide full biting force with your muscles of mastication.  After all, they are thicker, more robust teeth that can withstand those forces.\n\nIn contrast, your front teeth (canines included) are less robust and are not suited to withstanding heavy biting forces.  As a result, when the PDLs of your front teeth are stimulated, feedback is sent to the brain causing your muscles to reduce their force.\n\nWhen your jaw is in its "neutral" position (for lack of a better word that the lay person can understand), your molars will occlude with each other, but your anterior teeth won't (i.e. the shouldn't, unless you have some abnormality).  Your teeth are safe this way.  Move your jaw side to side or even forward a little, and what happens?  Your canines start to hit eachother, and through feedback from the canines' PDLs your brain knows to relax the muscles.  It is a protective mechanism for both your teeth and your jaws that prevents you from biting hard with your jaw in a position that can cause damage to the teeth or TMJ.  This is known as "canine guidance".\n\nIndividuals who, for one reason or another, move their lower jaws more than usual are rubbing their canines more, hence the attrition.\n\nThis is about as simple as I can make the explanation.  I hope it helps.  I'll bet you never knew there was so much to the profession of dentistry!

Although I really have no idea what you mean, the occipital bone is the infero-posterior bone of the cranial vault, aka the bone that covers the bottom and the back of the skull. The maxilla or maxillary bone is the bone in which the upper teeth are held and form the lower part of the cheek. The cheek bones are the zygomatic or malar bones. Is this what you mean?? The occipital and maxilla do not touch.

I didn't think it was horrible..I took my time studying all the given materials. I think the most frustrating aspect was pouring models - they start to set too early sometimes. Xrays..back up from the patient. If you can see where you're aiming in relation to to the patient's facial structure, you'll get a better xray. I learned too...not to aim it straight toward the tooth: In other words, for #14, raise it slightly higher than the upper jaw, then aim downward toward the tooth. That way, you get a decent shot of the roots too. You don't crop the xray, leaving only the tooth visible on the film. Kinda hard to expain without showing someone in person...But nah, you'll get it. It'll be fine. Good luck!!!

Here are two (see refs.). Note that the second one is a rotating 3-D model.

I had to get one to expand my top jaw. You normally have to get one because your upper or lower jaw isn't where it needs to be, and that will help it get to the position it needs to be in.

It depends on the model

Oh I wore the braces, had the head gear, the rubber bands, and also at the same time wore glasses! Yes, I was truly a geek! However I wore the upper retainer, and lost the bottom retainer while I was swimming in the lake. So now, at least my upper teeth are great, but somewhere there was a fish who found my bottom retainer! I still don't like that lake.

Yes but if you misalign it a lab can't fix it.  It is best if you take the to virgin pieces (a clean break) to your dentist the the lab makes a mold of the two pieces,  fabricates a repair that incorporates both pieces,  they are not glued together.

Your dentist should def. be able to tell the difference between a primary tooth and an adult tooth.  Depending on where it is located and what size it is in comparison to the other teeth.  Some people do not get a permanent tooth in one or more places, thus the baby tooth stays present in the mouth as there is not another tooth under it pushing it out.  The roots on baby teeth resorb so they can get ready to become loose and come out to make way for the adult teeth.  Even though there is not a root present the tooth can still remain in the mouth for several years, sometimes a lifetime if you are careful.  I have seen grown men with a primary tooth still in their mouth.  Maxillary perm molars (upper, back teeth) have three roots, and mandibular perm molars (lower back teeth) have two roots.  Depending on where this tooth is should tell your dentist if it is a primary or permanent tooth.  Some people do have their permanent tooth roots resorb for some reason, in this case if the tooth becomes loose then they would have to have an implant.  I know of a case where this happened to a lady in the dental field, she has excellent home care, it just so happened that a back molar root resporbed leaving the tooth loose, so she had an implant placed.  I am sure there is a way for your dentist to find out one way or another what is going on in your mouth.  Insurance companies can be very picky so don't give up, keep trying.

yes ... \n\nPostmenopausal women may significantly reduce tooth loss by controlling their periodontal disease, according to a study in the Journal of Periodontology. \n\nResearchers from the University at Buffalo, School of Dental Medicine did a follow-up evaluation on 106 postmenopausal women and found that during an average of 11.7 years follow-up, 57.5 percent of the participants lost at least one tooth. \n\n"We found that alveolar bone loss (the bone that holds the tooth in the mouth) is the strongest independent predictor of tooth loss in the postmenopausal population," explained Mine Tezal, DDS and study author. "Each millimeter of alveolar bone loss increased the risk of tooth loss 3 times, and the risk of tooth loss increased 2.5 times for each millimeter of clinical attachment loss, or soft tissue attachment between the tooth and alveolar bone." (This is also known as loss of gums and bone.) \n\nThe health of teeth depends upon the integrity of the alveolar bone holding them in the mouth. Periodontal disease is the major cause of alveolar bone loss and tooth loss in patients over 35.

Almost all mammals have two sets of teeth (this is called diphyodonty). One of the hypothesis to explain the existance of these two dental generations is related to the way our teeth work.\nThe teeth of adult mammals occlude (=come together) in very precise patterns that are related to the type of food and the way this food is chewed, and are very important for feeding efficiency. If the definitive teeth were to erupt in a young individual that is still growing, the growth of the skull and jaw bone could make the upper and lower teeth lose their occlusion, with negative consequences.\nSo the hypothesis proposes that the first generation or milk teeth appear during the first years (in humans, much earlier in other mammals), when the young one is feeding on breast milk, and then it is not so important that they become separated when the child keeps growing. \nOnly then they're replaced by the definitive ones. And remember, only incisors, canines and premolars have two generations. The molars (the most important for mastication) only erupt once, and they do so later, when the person is much more grown. In fact, the last molars or "wisdom teeth" sometimes do not erupt at all in humans.\n\nMore about mammalian teeth, jaws, and milk, at the Animal Diversity Web:\nhttp://animaldiversity.ummz.umich.edu/site/topics/mammal_anatomy/tooth_replacement.html

ask in your local dentist as they usually recieve the monthly magazine, they might be able to save it for you. You could contact the BDA website and see what links they have got that could be useful

over is when the teeth on top are further out.  Underbite is when the teeth on top are on the inside of the teeth.\n\nAn orthodontist can fix this by applying a device. maybe  wires and springs, which puts constant pressure on the teeth, and they move within the jaws.  Bone dissolves in front of them and reforms behind.

Yes.  Bone is being made in lab rats by use of cloning.  It will be many years before released for human use (if ever).  They can make new teeth too - in rats of course.  Baby human teeth have been cloned, but are not allowed to be placed in a human yet.

If you're referring to a human skeleton, yes, a good approximation can be done because our teeth have limited growth (they're brachydont) and we only have 2 generations, like most mammals. Therefore, an expert could see if the teeth are part of the milk or definitive dentition, and also assess the wear of the occlusal (grinding) surfaces. And not only the external appearance of the teeth is examined, but also the tissues (dentine, cement, enamel, pulp cavity).\nThere are standards to calculate age and they're normally used by forensic experts.\nA list of bibliography on the subject:\nhttp://users.breathe.com/malt/agedet.htm\nI've tried to find articles but none are free :-(\n\nHowever, other mammals have permanently-growing teeth, and therefore age determination is more difficult. And in other vertebrates that have more dental generations, other methods are used for age determination.
