Comparative Evaluation of Esthetic Materials Used for Fixed Partial Prosthesis Placed On Vital Abutments on The Periodontal Status: A One Year Retrospective Follow-Up

BACKGROUND: The replacement of missing teeth with fixed partial dentures is largely dependent upon the health and stability of the surrounding periodontal structures. FPDs are often prepared on vital teeth as abutments. Esthetic materials have become popular in fixed prosthodontics today. AIM: The present study aimed to assess the long term effect and tissue responses of various types of fixed partial prosthesis placed on vital abutment teeth on the periodontal parameters both clinically and radiographically. MATERIALS AND METHOD:  Following ethical committee approval, the study group comprised of 87 abutment teeth in 41 systemically healthy patients (24 males and 17 females) aged between 18 – 45 years who had received 3 unit fixed prosthesis(IPS empress, PFM or zirconia), having equigingival margins using vital teeth as abutments. The following parameters were assessed at the time of bridge placement and 1 year follow up – CAL, Probing depth, Distance between CEJ/ cervical crown margin and alveolar crest of the abutment teeth(radiograph). RESULTS: Statistical analysis carried out by SPSSV22 software revealed significant changes in clinical parameters with IPS empress and radiographic parameters with PFM and Zirconia from time of bridge placement till the 1 year follow up.(P<0.05). CONCLUSION: There seemed to be favorable responses of the periodontal tissues to the various esthetic materials used on vital abutments of FPDs.
