IMPLANT SUPPORTED SINGLE TOOTH REPLACEMENT IN THE AESTHETIC ZONE :A 10 year follow-up study of a prospective, randomized clinical trial comparing the treatment outcome of three augmentation modalities

(2016) Meijndert, C. (Caroliene)

OBJECTIVE: The aim of this randomized controlled trial was to assess the 10-year effects of three different augmentation techniques for implant supported restorations in the maxillary aesthetic region regarding clinical and radiographic parameters, and patient-centred outcomes.
MATERIAL AND METHODS: Ninety-three patients requesting single tooth replacement and presenting with a horizontal bone deficiency were included. After augmentation, 93 ITIEstheticPlus implants were placed. Clinical variables, standardised 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.
CONCLUSION: 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.
