In this post I want to show the bone regenerating effect from the narrow threads around the neck of an implant, brand ICX, 8” long, 4,8” wide. You can see the one-year evolution control on this following post
Day O: a second molar on the left upper jaw was extracted on May 9, 2011 due to a tooth fracture. The X-ray was taken after the extraction. The wisdom tooth is kept behind to minimite the alveolar resortion.
Three months later, on August 16, 2001 the ICX 4,8″x8″ was set with 35 N primary stability, by means of a punch technique and small vertical sinuslift, using a collagen membrane and autogenous bone. The implant was set further distal to the center space, counting already on the future extraction. The wund is sealed with a platform-switch healing screw.
Two months later, on October 18, 2011, I make another X-ray check, test the stability of the implant.The bone has grown around the narrow neck threads. The bone is condensed around the apex and the impact sound is excellent, showing a good integration.
I insert the closed-impression post. Now has come the moment of the extraction of the third molar (wisdom tooth), because it is no longer necessary and, furthermore, interferes with the plastic cap that goes over the post. The impression is taken therefore after the extraction.
Nine days later, on October 27, 2011, the abutment is screwed in with 35 N torque and the crown is cemented with temporary cement until the 6-moth control.
