- Fig. 1. a Patient 1—orthopantomogram (OPT) at age of 13. Situation before extraction of the ankylosed deciduous teeth 55, 54, 65, 74, 75, 84, and 85 and start of orthodontic treatment. Eleven permanent teeth (including 4 third molars) were congenitally missing. b Patient 1—post-orthodontic situation at age of 16. The top of the mandibular processus alveolaris is small (upper). The interdental space at location of the second premolars in the maxilla is 7 and 14 mm at location of the premolars in the mandible. Six dental implants were planned (locations 15, 25, 34, 35, 44 and 45). Implant placement (inclusive bone augmentation with the autogenous retromolar mandibular bone 3 months before implant placement at the place of the 25) was postponed until the age of 18. Essix retainers were used to safeguard the width of the diastemas : Three-dimensional computer-guided implant
- Fig. 2. a Patient 2—pre-implant orthopantomogram (OPG) at the age of 12. Situation before start of orthodontic and implant treatment. Eleven permanent teeth (including 2 third molars) were congenitally missing and the 34 is impacted. To erect the 34, orthodontic treatment was desired. Due to the lack of stable anchorages in the third quadrant, it was decided to place one implant at tooth region 35 for orthodontic anchorage and future prosthetics. Due to very limited bone height virtual implant planning was needed to avoid damage to the mandibular nerve. b Patient 2—mandible, pre implant intra-oral situation at the age of 12. The 34 is not visible in the oral cavity : Three-dimensional computer-guided implant

- Fig. 4. a Patient 1—virtual set-up of the ultimate treatment goal. b Patient 2—virtual set-up of the ultimate implant position. One short dental implant was planned in region 35, based on the location of the mandibular nerve (orange), the impacted 34 (pink) and the bone quality and volume. c Patient 2—virtual set-up of the ultimate prosthetic treatment goal : Three-dimensional computer-guided implant
