AIM: The adjustment and transfer of a stable occlusion can be a major challenge in prosthetic rehabilitations. The aim of the present study was to assess a noninvasive treatment option for complex prosthetic rehabilitations and occlusal analyses using 3D-printed restorations clinically.
MATERIALS AND METHODS: Eleven patients received a partial or complete rehabilitation with the aid of 3D-printed restorations (n = 171). After 12 months of clinical service, all restorations were analyzed using the United States Public Health Service (USPHS) criteria.
RESULTS: The 12-month clinical data revealed that 3D-printed restorations showed a survival rate of 84.4%. Complications occurred mostly regarding the anatomical form (7%) or marginal integrity (6%) and were consequently rated 'Charlie' or 'Delta.' Color stability and color match of 3D-printed restorations were rated 'Alpha' in 83% and 73%, respectively, of all restorations. Marginal inflammation was rated 'Alpha' in 89% of all restorations. An excellent surface texture and no secondary caries or postoperative sensitivities (100%) were observed.
CONCLUSIONS: 3D-printed restorations might be an alternative treatment option for initiating complex prosthetic rehabilitations. Technical complications rarely occurred. Biologic complications did not occur at all. The color stability showed promising results after 12 months of clinical service. However, the results should be interpreted with caution until long-term results with a high number of restorations are available.
