入选标准
- •Patients will be at least 18 years of age, of either gender, and of any ethnic background.
- •Each patient should have at least one carious lesion or defective restoration to be restored on a maxillary or mandibular premolar or molar tooth.
- •Each lesion or defective restoration should exhibit sufficient size or loss of tooth structure requiring a full crown restoration.
- •The tooth should have at least one opposing tooth in occlusion and one adjacent tooth with an intact proximal contact.
- •All teeth will test vital and be asymptomatic at the beginning of treatment. No more than two restorations will be placed per patient.
排除标准
- •Devital or sensitive teeth
- •Teeth with prior endodontic treatment of any kind
- •Teeth with a history of direct or indirect pulp capping procedures
- •Patients with significant untreated dental disease to include periodontitis and/or rampant caries
- •Women who self-report that they are possibly pregnant, pregnant, or lactating, as elective dental treatment is not indicated at these times
- •Patients with a self-reported past history of allergies to the materials to be used in the study including composite resin cements or ceramic restorative materials
- •Patients unable to return for the recall appointments
