Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Conventional
Conventional impression
A dental impression is a negative imprint of hard (teeth) and soft tissues in the mouth from which a positive reproduction (or cast) can be form using alginate material. They are made by using a container which is designed to roughly fit over the dental arches ("trays").
Digital 1
Digital Scan 1
Direct intra-oral digital scans using Sirona Omnicam software.
Digital 2
Digital Scan 2
Direct intra-oral digital scans using Planmeca Planscan software.
Digital 3
Digital Scan 3
Direct intra-oral digital scans using 3M True Definition software.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Good oral hygiene and compliance
* In need of a single full-coverage crown on any vital premolar or first molar tooth
