Evaluation of Fixed Denture Prosthetic Restorations with Pier Abutment

The aim of this study is to evaluate the prosthetic, periodontal, radiographic and clinical findings of the fixed on-tooth restorations with middle base and observe the changes of these values over time. 24 patients were included in our study, and these patients were measured twice, one year between measurements. Statistical analyzes were performed in IBM SPSS Statistical Software program (version 21; IBM, Armonk, NY). In these analyzes, parameters such as age, gender, distance between the abutments, bridge angle, occlusion type, opposite arc type, vitality of the teeth, amount of attached gingiva, root length, restoration length, gingival pocket amount of the abutment teeth, gingival index, gingival bleeding index, plaque index, their relationship with clinical attachment loss changes, ceramic fracture and complications were evaluated. According to the data of our study, findings that are compatible with the literature and provide new information to the literature in terms of clinical loss of attachment, occurrence of periodontal diseases or complications related to restoration in patients who underwent rigid fixed prosthetic restoration, and the changes recorded in the controls performed. For this reason, we believe that rigid fixed prosthetic restorations will be more advantageous in laboratory practice, since non-rigid restorations require more complicated laboratory work, and we believe that clinical and radiological complications do not have a definite relationship with the type of restoration.
