The second case was a 35-year-old female that had root canal therapy on the upper left first molar after 3 weeks delay after RCT (Figure 1).

No bevels were placed on the occlusal and gingival margins (Figure 3).
Peripheral enamel skeleton was built up in the distal part (Red Arrow) using wedge-shaped increments and placing appropriate length fiber in close contact with a palatal cusp (Blue Arrow).

Fibers were covered with a very thin layer of a flowable composite (Filtek Bulk Fill, 3M ESPE, USA); prior to insertion into the cavity, they were precontoured c-shaped and then carried into the cavity by cotton plier, and fitted into the cavity walls properly with thin composite spatule, bonded, and cured for 20 seconds. (Blue Arrow in Figure 4). Figure 4). Filtek Z250 A3 shade was used to build up the cervical third of both the distopalatal and distal surfaces of the tooth.

Single increments of A2 shade of Filtek Z250 were applied to each cusp separately, achieving the final occlusal morphology (Figure 5).
