Single crowns supported by short implants in the posterior region are a predictable treatment option with reduced failure rates, biological/prosthetic complications and minimal bone loss.

The 6-mm implants supporting single crowns performed well, but the mandible shows a higher risk of failure. The time and clinical C/I ratio are predictors for bone loss.

The Nd:YAG laser was the most effective surface treatment, followed by Rocatec and Al(2)O(3) sandblasting. A strong positive association was found between bond strength values and percentage of remaining cement.
