Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Congenitally missing tooth is one of the most common anomalies in human dentition. The treatment options of lateral incisor agenesis are closing the space with orthodontic treatment, implant treatment, conventional fixed dental prosthesis (FDPs) and resin-bonded fixed dentures (RBFDs). RBFDs are used frequently for single tooth absence in the anterior region due to their minimal invasive properties, high clinical success and patient satisfaction. With the development of new and stronger materials, RBFDs with metal framework have been replaced by glass ceramic, lithium disilicate, fiber-reinforced composite (FRC) and zirconia. The aim of this study is to evaluate the clinical performance of CAD/CAM single-retainer monolithic zirconia ceramic RBFDs which cemented with two different resin cements.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The aim of this study is to evaluate the clinical performance of CAD/CAM single-retainer monolithic zirconia ceramic RBFDs which cemented with two different resin cements.

The project includes 20 patients. Most of the patients have been recruited from the Istanbul Medipol University Dental Clinics in Istanbul. The patients were selected from individuals who have unilateral or bilateral congenitally missing maxillary lateral teeth and wanted to be treated a restoration or undergoing orthodontic treatment.

After giving their consent to take part in the study no preparations were made on abutment teeth for RBFDs. Digital impressions were taken with an intraoral digital scanner. The RBFDs were designed using a CAD software, milled and presintered zirconia blocks (KatanaTM Zirconia HT, Kuraray Noritake Dental Inc, Tokyo, Japan). RBFD was adhesively bonded to abutment teeth with one of the two different resin cements (Panavia F2.0 or Panavia V5).

The control procedure is:

The restoration is evaluated according to presence of mobility or debonding and fracture at the connector area. Gingival harmony and periodontal tissues around the restorations were also examined. Mobility of the abutment tooth was checked in the clinical examination and alveolar bone was examined with periapical x-ray. The controls will take place after two weeks, one year, two years, three years and five years.
