A 4.5x14 mm tissue-level implant is placed with insertion torque >60 Ncm (Fig.6 I, underprep); a 4x3 mm abutment (A) is placed immediately for an immediate provisional.
The patient is so afraid of X-ray that the next one is taken 1.5 years post cementation (Fig.8). It appears that dense bone bundle forms between the crest and the 1st implant thread (adaptation functional change, arrowheads).
The bone density continues to increase 2 years 8 months post cementation (Fig.9 *); the bone has grown into the area between the 1st 2 threads (arrow).
