A Minimally Invasive Approach Using a 4-mm Implant Without Extraction of Impacted Maxillary Canine: Four-Year Postloading Results

The aim of this case report was to suggest an alternative minimally invasive surgical approach to an impacted maxillary canine using a 4-mm-long implant for a fixed prosthetic rehabilitation, avoiding tooth extraction or surgically forced extrusion and exploiting the 6 mm of coronal bone availability. At 4 years postloading, the implant was healthy and well integrated with stable marginal bone levels. The 4-mm length of the implant reduced operative times, postsurgical morbidity, possible complications, and costs. Short implants might be an alternative to traditional, more invasive surgical procedures used in the rehabilitative treatment of impacted maxillary canines.
