The solution supports ATLANTIS abutments for cement- and screw-retained restorations as well as the ATLANTIS Conus Abutments custom for friction fit, removable restorations.
Dentsply Implants designs, manufactures and delivers the Atlantis abutments, the dental technician finalises the restoration and ships it to the clinician, who installs the final restoration in the patient's mouth.

This is the second part of a two-part article, and explains the techniques of making provisional restorations, such as the shell technique, the bulk technique for making a temporary restoration from scratch, or the basic technique of using the mold of the unprepared abutment in the preoperative impression, to form the temporary restoration.
A filter material is normally provided at the interface between the impervious blanket and rock abutment to control seepage (Widman, 1993).

Although the researchers in [1-5], as well as many others [6-10], have studied and analyzed the stress conditions of bridge abutments under the impact of temperature, live load, and creep and shrinkage, further efforts must be made to investigate the stress mechanism of abutment cracking during construction as a result of hydration heat, the cooling effect from changes in atmospheric temperature, the shrinkage difference between the concrete of the pile cap and the abutment body, and constraints applied by the pile foundations.
The present study encompasses petrographic, geotechnical studies of the foundation and abutment rocks and structural geology of the surrounding area.
