The role of dental implant abutment design on the aesthetic outcome: preliminary 3-month post-loading results from a multicentre split-mouth randomised controlled trial comparing two different abutment designs.

CONCLUSIONS: The preliminary results of the comparison between two different abutment designs did not disclose any statistically significant differences between the evaluated abutments. However the large number of missing radiographs and clinical pictures casts doubt on the reliability of the results. Longer follow-ups of wider patient populations are needed to better understand whether there is an effective advantage with one of the two abutment designs. Conflict of interest statement: This research project was originally partially funded by Biomax (Andover, MA, USA), the manufacturer of the Curvomax abutments evaluated in this investigation. Biomax, under pressure from some investigators, asked to modify the original agreed protocol. In a following phase, Zimmer-Biomet (Palm Beach Gardens, Florida, USA), the manufacturer of the implants and the GingiHue abutments, took over the funding of this project. Data belonged to the authors and the sponsors did not interfere with the publication of results. PMID: 29557402 [PubMed - in process]
