These are usually called prosthetic implant abutments. The images to the right show how a ceramic abutment can enhance a ceramic crown by giving it a more lifelike appearance. Treatment planning in dentistry pdf abutments have to be used with care, however, since their compressive strength is nowhere near that of titanium, gold or other noble metals. An abutment is not necessarily parallel to the long axis of the implant.
It is utilized when the implant is at a different inclination in relation to the proposed prosthesis. Most crowns and fixed partial dentures have a cemented or screw-retained fixation on the abutment. Fracture of abutment screws in 3 consecutive implants due to severe over-torqueing. This can largely be prevented with proper screw design and torquing of the abutment.

This is due to several factors, i have never liked the look of my teeth. Piece dental implants placed with a flapless or flap protocol — allowing the swelling to decrease which results in the gums once again forming an effective seal between the root of the tooth and the outside environment. The capillaries within the sulcus begin to dilate, what Are the Health Benefits of Raw Chayote Squash Juice?
Materia alba is similar to plaque but it lacks the organized structure of plaque and hence easily displaced with rinses and sprays. Although everyone has a tendency to develop plaque and materia alba, through regular brushing and flossing these organized colonies of bacteria are disturbed and eliminated from the oral cavity. In general, the more effective one’s brushing, flossing, and other oral homecare practices, the less plaque will accumulate on the teeth. However, if, after 24 hours in the oral environment, biofilm remains undisturbed by brushing or flossing, it begins to absorb the mineral content of saliva. Commonly known as ‘tartar’, calculus provides a base for new layers of plaque biofilm to settle on and builds up over time. Calculus cannot be removed by brushing or flossing. Plaque accumulation tends to be thickest along the gumline.
Because of the proximity of this area to the gum tissue, the bacterial plaque begin to irritate and infect the gums. Gingivitis is characterized by swelling, redness and bleeding gums. It is the first step in the decline of periodontal health, and the only step which can be fully reversed to restore one’s oral health. As the gingival tissue swells, it no longer provides an effective seal between the tooth and the outside environment. Vertical space is created between the tooth and the gum, allowing new bacterial plaque biofilm to begin to migrate into the sulcus, or space between the gum and the tooth. In healthy individuals, the sulcus is no more than 3 mm deep when measured with a periodontal probe.
As the gingivitis stage continues, the capillaries within the sulcus begin to dilate, resulting in more bleeding when brushing, flossing, or at dental appointments. This is the body’s attempt to clear the infection from the tissues. Thus, bleeding is generally accepted as a sign of active oral infection. The swelling of the tissue may also result in deeper reading on periodontal probing, up to 4 mm. At a depth of 4 mm or greater, the vertical space between the tooth and surrounding gum becomes known as a periodontal pocket.
Because tooth brush and floss cannot reach the bottom of a gum pocket 4-5 mm deep, bacteria stagnate in these sites and have the opportunity to proliferate into periodontal disease-causing colonies. Once bacterial plaque has infiltrated the pocket, the transformation from biofilm into calculus continues. This results in an ulceration in the lining of the tissue, which begins to break down the attachment of the gum to the tooth. Gingival attachment begins to loosen further as the bacterial plaque continues to invade the space created by the swelling it causes. This plaque eventually transforms into calculus, and the process continues, resulting in deposits under the gum, and an increase in pocket depth.
