Abstract
Background: Dental porcelain (also known as dental ceramic) is a dental material used by
dental technicians to create biocompatible lifelike dental restorations, such as crowns, bridges,
and veneers. Evidence suggests they are an effective material as they are biocompatible,
aesthetic, and insoluble and have a hardness of 7 on the Mohs scale. For certain dental
prostheses, such as three-unit molars porcelain fused to metal or in complete porcelain group,
zirconia-based restorations are recommended. The word "ceramic" is derived from the Greek
word κέραμος keramos, meaning "potter's clay". It came from the ancient art of fabricating
pottery where mostly clay was fired to form a hard, brittle object; a more modern definition is
a material that contains metallic and non-metallic elements (usually oxygen).
Aim: - The aim of study was to assess the marginal adaptation of various class II ceramic
restorations.
Materials and Methods: - The study involved all the patients who attended the University for
Class 2 Restorations, for whom ceramic restorations were given.
Results: - The maximum number of treatment done was for the male population and it was
class II ceramic inlay DO and the least number of treatment done was class II ceramic inlay
MOD for the male patients. Maximum number of class II restorations were done in 36 (lower
left molar). For class II ceramic inlay DO grade A was given for 23.53% of the total procedures
but for class II ceramic inlay MO for 23.53% were given a B grade and 16.18% only were
provided with A grade. That indicates that class II ceramic inlay DO were done more with more
perfection than others which in turn indicates that class II ceramic inlay DO have better
marginal integrity and shade matching when compared to the other restorations done.
Conclusion: Hand skills of a clinician definitely decides the longevity and durability and the
properties of any treatment that is delivered to a patient, through our study we have assessed
marginal adaptation of class II ceramic restorations found to be very good.
