[Gingivo-dental sparing strategy of orthodontic treatment (fitting with permanent dentures)]
Abstract:
Development of inflammatory process in the marginal part of the mucosa is caused not only by epithelial injury during tooth preparation and dental plaque accumulation, but by irregular contour and position of the artificial crown edge as well. Clinical, x-ray, and cytoenzymological studies showed that orthodontic treatment with cermet and polyceramic dentures with fixation of the supporting elements at the level of the gingival edge in tissues adjacent to the tooth causes the slightest pathological changes. The compensatory adaptive processes in this area of the buccal mucosa are the most pronounced if preparation of hard dental tissues is combined with closed currettage of periodontal pouches, which was confirmed by remote clinical results and laboratory findings in patients with slight and medium-severe periodontitis.

In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
