The current narrative review was planned to discuss various techniques for the use of natural tooth pontic, which preserves the original contours, size and colour of the replaced tooth. Before using these teeth in …


Radiographic Evaluation Of The Margins Of Clinically Acceptable Metal-Ceramic Crowns, Sheikh Bilal Badar, Kamil Zafar, Rabia Ghafoor, Farhan Raza Khan Feb 2022

Radiographic Evaluation Of The Margins Of Clinically Acceptable Metal-Ceramic Crowns, Sheikh Bilal Badar, Kamil Zafar, Rabia Ghafoor, Farhan Raza Khan

Section of Dental-Oral Maxillofacial Surgery

Objective: To radiographically evaluate the proximal marginal fit of the clinically acceptable metal-ceramic crowns.
Methods: The prospective study was conducted at the dental clinics of Aga Khan University, Karachi, from July to December 2018, and comprised metal-ceramic crowns that were evaluated prior to the cementation. Clinical examinations were conducted by seating the crown on the tooth preparation and visual assessment was done using sharp explorer along the margins. Clinically acceptable crowns were then evaluated on the bite-wing radiograph. Any horizontal or vertical inaccuracy of >0.5mm at the proximal margins was recorded as 'discrepancy'. Data was analysed using SPSS 22.
Results: …
