简要总结
First, Participants in this study will be recruited according to inclusion criteria. Proper examination for the participants (clinically and radiographically). Preparation for endodontically treated molar for receiving high performance polymer endocrown. Checking and verification for the restoration (trying) and assessment of marginal and internal fit by replica technique. Then final cementation of endocrown.
详细描述
Examination and diagnosis:
Selection and examination of the patients according to inclusion and exclusion criteria. Diagnosis of the patient's chief complaint and teeth that will be involved in this study will be done.
Primary alginate impressions for diagnosis on primary casts and for mounting. The patients will be asked to maintain good oral hygiene measures by using tooth brush twice daily.
Taking a professional pre-operative photo.
Tooth preparation procedure:
