Introduction/Context/Diagnosis

A- 54 years female presented with chief concern “Since I got my posterior crowns, my gum is bleeding so easily even with brushing and eating! Also, I feel that it is always tender, inflamed, and sore specially my bottom right side. Also, I lost my night guard and I want to have a new one.” clinical findings revealed that all teeth received indirect lithium disilicate restorations. Radiographs showed marginal discrepancies and ledges on teeth # 2, 14, 18, 20, 29, 30, 31. Gray Discoloration noted on cervical third of teeth # 22-27.

Methods/Treatment Plan

Replacing all ceramic indirect restorations on teeth # 2, 14, 18, 20, 29, 30, 31 using TRIOS digital scanner and CAD/CAM techniques.

Results/Outcome

Significant improvement of periodontal health by replacing crowns with marginal discrepancies.

Significance/Conclusions

One of the main goals of a long term successful restorative therapy is to create a physiologic periodontal environment that facilitates the maintenance of periodontal health. Large marginal discrepancies can cause plaque retention which negatively affect gingival index and crevicular fluid volume. Subsequently, lead to periodontal tissue inflammation with or without bone loss
