Temporary crowns: Repositioning key as a new technical approach in the clinical relining phase

To accomplish prosthetic rehabilitation, a series of important procedures must be followed to achieve the correct final prosthetic outcome. The protocol presented in this article proposes a different approach that involves relining the temporary crowns during the provisional phase by means of a repositioning key. This approach is especially useful for therapeutic provisional restoration in patients with temporomandibular joint disorders. CLINICAL SIGNIFICANCE The methodology presented allows the exclusion of arbitrary repositioning in the three-dimensional space of the provisional restoration, considering it as a fixed starting point. Our results tend to emphasize this technique not only for the ease of use, but also for the shorter time required for the occlusal fitting procedures in the final finishing phases.
