Abstract :

[en] AIMS: The aim of this study was to evaluate the two-year outcomes of the One Tooth-One Time (1T1T) completely digital workflow, allowing the immediate loading of a single implant in the posterior region with a final CAD-CAM crown made of a polymer-infiltrated ceramic network (PICN). MATERIALS AND METHODS: A series of 10 implants were placed, and an intra-oral scan was taken after the surgery. A final screw-retained PICN crown was manufactured chair-side and placed the same day in full occlusion. Marginal peri-implant bone changes and soft-tissue health were evaluated, as well as restoration performance using World Dental Federation criteria and Pink and White Esthetic Scores. Patient-related outcome measures (PROMs) and time consumption data were collected. RESULTS: After two years, the implant survival rate was 100%. The debonding of one crown from its Titanium Base led to a 90% prosthodontic survival rate and the remaining crowns were all considered successful. The mean marginal peri-implant bone changes yielded 0.87 (SD: 0.96) and 0.55 (SD: 0.53) mm after one and two years, respectively. Mild or no inflammation of peri-implant soft tissue was observed in most implants. The overall treatment time reached 175 min and PROMs displayed high patient satisfaction. CONCLUSIONS: This study constitutes the first report considering immediate loading of a single implant in the posterior region with a final crown in occlusion. In this case-series, the two-year outcomes of the 1T1T protocol seem rather promising and fulfil patient expectations. However, those preliminary results need to be confirmed by randomized control trials and patient selection is probably a key factor in this procedure success.
