Initial CBCT (CS 9300®, Carestream Dental, Atlanta, GA, USA) that revealed a limited bone height (< 8 mm from the top of the crest to the inferior alveolar nerve) in the posterior left mandible. The 69 years old female patient was referred to our clinic and since she had experienced in the past failures with bone regenerative therapies, she did not want to undergo bone regeneration; the placement of a standard length endosseous implant was therefore not possible, and the only possibility was the placement of an extrashort (6 mm) endosseous implant
