As already explained in our blog in the first part of the case by Dr. Jes\u00fas L\u00f3pez Vilagran \u201cSingle Biomimetic Iceberg immediate implant (18\/03\/2021)<\/a><\/strong>\u201d, preserving the socket during the placement of an immediate post-extraction implant can compensate the socket remodelling process and promote bone formation. In addition, the use of an immediate provisional will, at the same time, help improve the final aesthetic results.<\/p>\n\n\n\n

In this case, an immediate provisional prosthesis was made using a\ncustomised titanium abutment screw-mounted to the implant. The impression was\ntaken of the abutment and the acrylic provisional with flowable composite and\nthe emergence profile was defined freely until an outlined crown was achieved\nthat replicated the condition of the tissues prior to the extraction and\nmaintained them during the healing period of the implant.<\/p>\n\n\n\n

After a 3-month healing period, the provisional restoration was unscrewed and a digital impression of the emergence profile was taken immediately with a Trios (3Shape) scanner<\/a><\/strong>. A second scan was taken with a scan abutment screw-mounted onto the implant. The two scans were superimposed by the Dental System (3Shape)<\/a><\/strong> software so as to have all the information and to be able to proceed with the design of the definitive restoration.<\/p>\n\n\n\n

It was decided to design a single restoration in zirconium on a customised Avinent titanium base<\/a><\/strong>. This type of interface makes it possible to perfectly customise both the emergence profile and the height of the cementing with the zirconium. These are common problems of standard interfaces, when it is necessary due to the type of case, and thus it is possible to replicate the emergence profile achieved with the provisional prosthesis that has been in the patient’s mouth for the preceding months.<\/p>\n\n\n\n

As can be observed in the following sequence of images, the full volume\nof the crown was designed with Dental System (3Shape), and the restoration was\nthen segmented into primary (gold titanium) and secondary (Ivoclar Prime\nZirconium).<\/p>\n\n\n\n
