Abstract

OBJECTIVES: 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 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 (T1 ), 12 months (T12 ) and 120 months (T120 ) after final crown placement.

RESULTS: 10-years implant survival was 95.7% and did not differ between the groups neither were significant differences observed in the other treatment outcomes assessed. Peri-implant bone loss was low, viz. 0.48 ± 1.19 mm (mesial) and 0.30 ± 1.24 mm (distal) at T120 . Loss of midbuccal marginal gingival level at T120 was 0.32 ± 0.83 mm. Mean overall satisfaction at T120 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.
