The patient is still using permanent and re- movable retainers The persistent primary tooth 55 was scheduled for extraction. Restoration of all the missing premolars was planned using implant-supported ceramic crowns. _Implant treatment CBCT was performed to evaluate the ana- tomical and surgical conditions, and to plan the surgical treatment. Owing to sufficient height and width of the alveolar process at the implant sites, guided bone regeneration was not requi- red. TSIII implants (OSSTEM; 4 mm × 10 mm S, 3.5 mm × 10 mm M) were used in regions 14 and 24, and TSII implants (OSSTEM; 3.5 mm × 10 mm M, 3.5 mm × 10 mm M) were used in regions 35 and 45. However, delayed implantation in region 14 was performed four weeks after the extrac- tion of tooth 55 (Figs. 7, 8a-c). _Prosthodontic treatment Recontouring of the central incisors was performed using the direct method with GRA- DIA DIRECT composite (GC Europe) and a two- Figs. 16a, b_The maxillary and mandibular arches after prosthodontic treatment.
