Abstrakt:	Objective: This case report presents a novel technique for bridge restoration using polytetrafluoroethylene (PTFE) tape and split dam isolation in situations where achieving complete dental dam isolation is challenging. Clinical Considerations: Achieving high-quality isolation by controlling gingival crevicular fluid and intraoral relative humidity is important during cementation. However, an improved technique during bridge restoration is needed due to the difficulties faced with dental dam isolation. A porcelain fused to zirconia bridge extending from the maxillary canine to the first molar was used to demonstrate the novel restoration technique in this case report. Split dam isolation lowers the relative humidity in the oral cavity, and PTFE blocks the gingival crevicular fluid. The effects of combining PTFE tape with split dam isolation on isolation (controlling crevicular fluid, saliva, and relative humidity in the operative field) were similar to those obtained with dental dam isolation and made for easier removal of excess cement. Conclusions: The novel technique introduced in this case report can enhance isolation quality during bridge restoration. (©Operative Dentistry, 2024.)
