In this section, the failure behavior of the concrete arch dam obtained from the FE simulation using practical mechanical parameters of rock abutments (listed in Table 2) is presented and discussed with focus placed on cracking process during overloading.
Deformation value decreases as the deformation position goes to the implant abutment. The deformation distribution of implant presents the symmetry by means of the central axis of the tooth.
Now DENTSPLY Implants moves forward to strengthen the intraoral scanning service for ATLANTIS abutments by collaborating with 3Shape, a company specializing in the development and marketing of 3D scanners and CAD/CAM software solutions.
- US-based medical device company Dentsply Implants has expanded its connectivity offerings by introducing intraoral scanning for Atlantis abutments with 3Shape TRIOS, the company said.
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.
By removing and re-seating the crown repeatedly until the crown is set hard, the assistant can make the temporary crown rub against any undercuts that maybe in the abutments. This shapes the inner surface of the temporary crown so that it glides over the undercuts, instead of locking into the undercuts, which would happen if the temporary crown was just left on the abutment to polymerize completely.
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.
Pineyro Arch Instruments numbers 1-3 have a unique crescent shape and are anatomically designed to fit around locator abutments for removable prosthetic hygiene applications.
This study, an experimental laboratory study, used a stainless-steel master model consists of two abutments which has the same shape with full crown preparation.

Wang and Zhou [2] highlighted the cracking associated with tall abutments as a critical issue in highway construction.
Professionals have previously used a healing cap as a surrogate within such applications, but these healing abutments do not provide the level of accuracy required for fixed restorative implant cases.
