Linear measurements in millimetre: PM-BC: distance from the peri-implant mucosa to the buccal bone crest; PM-LC: distance from the peri-implant mucosa to the lingual bone crest; PM buccal-IS: distance from peri-implant mucosa to the implant shoul- der in the buccal aspect; PM lingual-IS: distance from peri-implant mucosa to the implant shoulder in the lingual aspect; IS-BC: distance from the top of the implant shoulder to the first bone-to-implant contact in the buccal aspect; IS-LC: distance from the top of the implant shoulder to the lingual bone crest.

Rationale for platform switching The switch in implant platform diame- ter prevents apical migration of the epi- thelial attachment and soft-tissue in- growth at the top of the platform by reducing bacterial migration and, conse- quently, of soft-tissue ingrowth and peri-implant bone loss. Marginal bone loss is drastically reduced and the objective criteria for peri-implant inflam- mation are greatly improved.22 Human study Table 5 lists clinical parameters from human studies at one, three and five months. Figures 3a to h show radiological findings at one, three and five months. Figures 4a and b show the customisation of a SKY elegance abutment. Rationale for single-stage treatments Successive insertions and reconnec- tions when restoring an implant accord- ing to conventional protocols provoke bacterial invasion and colonisation of the biological space and mark the onset of marginal bone loss. Offering treat- ment in a single session provides the biological benefits described and saves time and money, increasing patient sat- isfaction.23 Intraoral scanning Fabricating a CEREC crown requires a step prior to intraoral scanning, namely the adaptation of the prosthetic sup- port. The SKY elegance abutment can be cut and customised in the mouth, more or less like dentin, which means a reduc- tion in time and cost. Also required are a delicate surface polish and prepara- tion of the profiles to be recognised by the intraoral scanner. The restoration margins should be well-defined and prepared to the gingival or subgingival level.24, 25 The SKY elegance abutment anatomy allows to create a proper emer- gency profile that can be customised for According to the 11th European Consensus Conference (EuCC) 2016 in Cologne, provided the specific treatment parameters are ob- served, the use of short, angulated or diam- eter-reduced implants in sites with reduced bone volume can be a reliable treatment option, given the risks associated with the use of standard-dimension implants in combina- tion with augmentation procedures.
