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.

(8,9) This has resulted in an emphasis on the surface of the prosthetic abutment as a means of minimizing plaque accumulation; most implant abutments now have a polished surface to eliminate roughness that may serve as a nidus for plaque formation.
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.
