This case report demonstrates the implant treatment of several congenitally missing teeth for an eighteen-year-old male and its long-term follow-up. In total ten teeth were missing: #13, #12, #22, #23, #25, #35, #32, #31, #41 and #45. Before implant placement an orthodontic treatment was carried out for the re-distribution of the space. The implant treatment was carried out in two steps. Six implants were placed and restored in the anterior maxillary and anterior mandibular in 2009. After about one year further three implants were placed, one in maxillary left posterior region after sinus lift and two short implants replacing tooth #35 and tooth #45. Clinical and radiographic examinations were performed in July 2017 to evaluate the soft tissue and crestal bone level around implants showing stable peri-implant bone levels, healthy and intact peri-implant mucosa and excellent maintenance of aesthetic results.
