The potential locations for implant placement and corresponding implant lengths and widths were planned in a prosthetically driven manner. A dis- tance of at least 3mm from the neck of the implant to the gingival zenith was applied, allowing the bi- ologicalwidthtocreateaconnectivetissuecontour around the abutments (Figs. 5 & 6). _Surgical procedure The surgery was performed under local and re- gional anaesthesia.
