abutment (cm).
Although the closed-form solutions in Table 1 revealed some characteristics of the side
abutment pressure distribution, none of these closed-form solutions include all the necessary parameters which include the properties of the coal, the properties of the interface between coal and roof/floor, the roadway height, and the support strength.
Unlike metal
abutments, which cause an unpleasant appearance in a fine gingival biotype [6], the use of zirconia
abutment allows light scattering and customization for each individual case.
The bus then struck a bridge
abutment and turned over.
Among various geological defects of rock
abutment which might be encountered in practice, nonuniformity is a typical one.
The technical problems of implant-based restoration components including
abutment screw fracture and periimplantitis are deeply related to dental implant system failure, and an increase in related complications are also being reported [3-5].
The reason is that horizontal force can generate a larger moment than other loading on the neck of the implant
abutment. Vertical force acts directly on the
abutment of implant.
The friction grip relationship eliminates micro movement between the
abutment and the implant, eradicating microbial colonization at the interface, and reducing bone loss at the crestal level.
This textbook describes dental implant
abutments in 10 chapters on their materials, retaining screws, different implant-abutment connections, prefabricated implant
abutments, the use of CAD/CAM (computer-aided design/computer-aided milling) technology in custom
abutment manufacturing, the relationship between
abutment geometry and peri-implant tissue in esthetic zone cases, instrumentation for
abutment modification, preparation techniques for one-piece titanium and zirconia implants, and cleaning, disinfection, and sterilization techniques.
Figure 1 (right) shows the
abutment and provisional as presented during the first appointment.
The work involves strengthening the Rhyl side reinforced concrete
abutment structure which has deteriorated since construction in 1932.
Geostudio analysis as well as field data has indicated that previous grout work at left and right
abutments has failed to produce the required results and seepage which is being measured at the downstream toe of the dam is through the
abutments instead of through the body or foundations of the dam and recommends that by extending the grout curtain up to a depth of 140' in case of left
abutment and to a depth of 160' in case of right
abutment, the quantities of seepage can significantly be reduced.
TEMPLETON - A Worcester man was killed on Route 2 Saturday when the Volvo he was driving slammed into a bridge
abutment for the Otter River Road overpass about noon.
The present study encompasses petrographic, geotechnical studies of the foundation and
abutment rocks and structural geology of the surrounding area.
