Fig.2: The 1st (7x11 mm) implant is 4 mm from the inferior alveolar canal.
In the 2nd procedure, osteotomy is deepened by approximately 2 mm. A 7x14 mm tap is inserted (Fig.4). There is apical space (arrowheads) to be engaged further.
The apical space disappears when a 7x14 mm implant (Fig.5 I) is placed. A: abutment.
The implant remains stable 4 months postop without bone resorption (Fig.7).
There is no bone resorption 6 months post cementation (12 months postop, Fig.8,9).
Mild bone resorption is observed 3 years post cementation (Fig.10).
