This score increased significantly after placement of the implant restoration, to a mean score of 90.1±6.5 at the T 12 follow-up ( Table 5 ). Five participants did not wear any prosthetic construction at baseline and could not answer the questionnaire. They were thus excluded from this part of the analysis. Complications Four participants reported mobility of the provisional restoration 2 weeks after placement. The screws could be retightened without further complications. One patient had suffered extensive marginal bone loss during the three months with the temporary restoration so it was removed and the peri-implant region was surgically explored and chemically cleaned using 35% phosphoric acid gel (Hentenaar et al., 2017). The area was augmented with a mixture of autologous bone from the tuberosity region and 4
