Three years clinical outcome of hybrid fixed-fixed bridges

Abstract

Subject: Hybrid fixed-fixed partial dentures present a conservative approach to the conventional type when a single tooth is replaced in the posterior region with certain indications. Aim: To evaluate various criteria’s like, post-operative sensitivity, gingival response, de-bonding of the retainer, secondary caries, retainer fracture resistance and patient satisfaction. Materials and methods: A total of 16 bridges were included in this clinical study. The patient selection, preparation techniques as well as bridges constructions were followed the current principles that recommended by the manufactures instructions and recent textbooks. Patients were clinically evaluated after 3 months from the final cementation. At 9, 18, and 36 months as follow-up period the patients were called by phone. Results: A good rate success was observed during the different evaluation periods. Gingival inflammation of one case was reported during 18 month evaluation, while two cases with de-bonding and post-operative sensitivity were recorded during the 36 month. 100% of patients were satisfied with these types of restorations. Conclusions: Hybrid fixed-fixed retained bridges appear to be an effective restoration in a single posterior missing tooth. Practitioners should consider its use as an alternative to bilateral full crown retained restorations.
