Image	Photo Description
	Fixed orthodontics used to retract severe labial inclination. 1) & 2) Pre-operative views. Note the upper and lower central incisors. 3) & 4) Following six months of treatment. Again, note the upper and lower central incisors. Braces move teeth through bone like moving a basketball pole through wet cement using anchorage and elastics. Note the three teeth connected with wire are being used as an anchorage unit while one tooth is being pulled by the elastic band.

	Crown and bridge repair. 1) - 4) Patient presented with a two-unit porcelain fused to metal bridge that had come out. The bridge abutment was on the upper left canine #11 and it was cantilevered in the upper left lateral position #10. The patient had recently moved to NY and then lost his job in the computer industry and was financially unable to properly rebuild this area at this time. The patient sought a temporary repair though he knew this would ultimately sacrifice the already badly damaged, and possibly untreatable, canine. 4) The canine abutment had significant decay. 5) The decay was removed from the canine and a post space created. 6) A pre-fabricated post was cemented into place. 7) A chemically cured bonding material was added to the post and the bridge was placed on top, and occasionally removed, during hardening. 8) The bridge was cemented onto this new abutment using chemically cured bonding material and a little bonding was also added to the distal of the left central #9 to help support the cantilever during vertical loading. The patient understands the need for more comprehensive care when circumstances allow.
Information about these dental photos In medicine and dentistry "left" and "right" are based upon the orientation of the patient's body and not how they appear in a photograph of a smile. For example, a reference to the upper left teeth will actually appear to be on the right side when viewing a picture of the face and similarly an upper right tooth will appear to be on the left side. Many words in dentistry like oral and mouth have a similar meaning and are frequently used together to help our readers find specific words they best understand. This is particularly important because a majority of our visitors are from countries where English is not their primary language. Maxilla or maxillary refer to the upper jaw. Mandible or mandibular refer to the lower jaw. There are many other similar word combinations used throughout this website because our pages are read by patients and dentists. A few of the most common are discussed here. Tooth decay, tooth cavity and dental caries all mean the same thing. Tooth, teeth and dental are also frequently interchanged as in teeth veneers or dental veneer laminate. Oral rehabilitation and dental reconstruction mean smile makeover. The word for x-ray may be used with or without a hyphen (this is true for other words too) and can also be called a radiograph.
