Badly Decayed Teeth andTeeth Restored With Large Filling Restorations and Endodontically Treated Teeth and Malformed Teeth and Malposed Teeth
Conditions
Brief summary
All ceramic crowns are indicated in case of mild to moderate discoloration, restoration of traumatized or fractured teeth and abnormal tooth anatomy. The success of dental restorations is determined by four main factors: biocompatibility, aesthetic value, resistance to fracture and marginal adaptation. . An inadequate marginal fit may compromise the longevity of the restoration since cement film exposure to the oral environment can lead to its dissolution . . Polyetheretherketone (PEEK) is a polymer that has many potentials uses in dentistry. Polyetheretherketone (PEEK) can be used to support fixed dental prostheses. However, information about physio mechanical characterization is still scarce. Aim of the study: \- The aim of this study is to evaluate the internal fit of milled BioHPP PEEK-based versus zirconia-based single crowns.
Interventions
OTHERBioHPP PEEK copings veneered with composite resin
In the first visit, a Face-to-Face adherence session will be held in which the patient should be informed about the study steps and how to maintain oral hygiene measures. Further sessions will occur at the follow-up visits . Participant patients will be asked about any problems they are having. Patients will be recalled every two months for one year for follow up visits.
