Eligibility

Inclusion criteria

Inclusion criteria: a) Subjects needing a crown on either 2nd Premolar or 1st molar of any arch. b) Subjects having normal Class I Angle’s occlusion. c) Presence of natural antagonist against the proposed full coverage restoration. d) Presence of same tooth on the contralateral side with natural antagonist for comparative analysis. e) Subjects with similar facial biotype.

Exclusion criteria

Exclusion criteria: a) Subjects with parafunctional habits, for example bruxism. b) Subjects with temporomandibular joint disorder and habit of unilateral mastication. c) Subjects likely to shift out of the area within the 6 months duration of the study. d) Subjects with excessive wear of posterior teeth i.e. dentinal exposure. e) Subjects with restored antagonist tooth opposing the test group tooth or the contralateral side tooth.
