| industry 26 implants 4 2016 made the permanent crown. The temporary crown with PEEK abutment was easily repositioned. In this case, I arranged for the crown to be returned from thelabseparatelyfromtheabutment.Theconstruc- tion then had to be fitted from the model of the mouth with a transfer key (Fig. 11a) because the structure is not indexed (therefore, it can be ce- mented in several ways because there is no internal indexation such as a trilob or internal hex). After fit- ting the crown, which was optimum in both colour and shape, the structure was ‘fixed’ using Safe-Lock (Fig.11b).Thisdeviceisconnectedtothemicro-mo- tor and gives short micro-strokes after activation using the foot pedal. Five strokes are enough to lock the abutment in place in the implant. The cold weld is then complete. I then cemented the crown accu- rately in the mouth with luting cement. At the six- month (Fig. 12a) and 20-month (Figs. 12b–c) check- ups,agoodadaptationofthemucosawasseen,and the results were considered to be good. Case 2 The second patient (25 years of age) approached me at the initiative of a dental student who had read an interview about my first experiences with narrow implants.Thispatientwasnolongersatisfiedwiththe bonded bridge that replaced her 22 due to agenesis.
