| Abstract [eng] |
Crown margin repairs, in some extent and based on the clinical situation, are an acceptable treatment option to restore the functionality and aesthetics of the compromised crown margin in prosthetic dentistry. The process of a repair is minimally invasive and saves aesthetic, time, and expenses for the patient. It is important to be familiar with the repair materials available, to know the techniques for a successful repair and to be able to fulfil the patient’s requests. Impaired crown margins not only have bad aesthetics, but also prove to be a risk of caries lesions and the loss of structural integrity of the whole crown and abutment tooth complex. The purpose of this literature review is to inspect the longevity of crown margin repairs as well as the survival rates of different repair materials. Therefore, the composition of crown margins will be outlined, diagnostic criteria reviewed, and the direct and indirect techniques will be discussed. Additionally, clinical outcomes are compared, and the advancements and limitations of crown margin repairs will be concluded. Finally, all results are put into context and will be analysed. |
