20 Chapter 2 Abstract Aim: The aim of this randomized controlled trial was to assess the 10-year effects of three different augmentation techniques (augmentation with chin bone, augmentation with chin bone plus a membrane and augmentation with a bone substitute plus a membrane) for implant supported restorations in the maxillary aesthetic region regarding clinical and radiographic parameters, and patient- centred outcomes. Materials and methods: Ninety-three patients (44 male/49 female, mean age 33 years) requesting single tooth replacement and presenting with a horizontal bone deficiency were included. After augmentation, 93 implants were placed. Clinical variables, standardized radiographs and photographs and patient questionnaires were analysed to assess the impact of the various augmentation techniques 1 month (T 1 ), 12 months (T 12 ) and 120 months (T 120 ) after final crown placement. Results: The 10-years implant survival was 95.7% and did not differ between the groups, nor were significant differences observed in the other treatment outcomes assessed. Peri-implant bone loss was low, being 0.48±1.19 mm (mesial) and 0.30±1.24 mm (distal) at T 120 . Mid-buccal marginal gingival recession at T 120 was minor, being 0.32±0.83 mm. Mean overall patient satisfaction at T 120 was 8.6 with 98.6% of the patients satisfied. Conclusions: Clinical, radiographic, aesthetic and patient centred outcomes were very favourable after 10 years and did not differ between the groups with different bone augmentation techniques.
