Dental Prosthesis
Conditions
Brief summary
This study aims to compare how a single cap best fit on a tooth that is fabricated with digital and conventional impression techniques.
Interventions
PROCEDUREConventional 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).
PROCEDUREDigital Scan 1
Direct intra-oral digital scans using Sirona Omnicam software.
PROCEDUREDigital Scan 2
Direct intra-oral digital scans using Planmeca Planscan software.
PROCEDUREDigital Scan 3
Direct intra-oral digital scans using 3M True Definition software.

Inclusion criteria
* Age of patient ≥ 18 years old * Good oral hygiene and compliance * In need of a single full-coverage crown on any vital premolar or first molar tooth * Opposing tooth is free of indirect restoration (crown) * Asymptomatic tooth free of pathology * No requirement for additional treatment (endodontic treatment, post and core, crown lengthening) * Anticipated supragingival or equigingival crown margin * Anticipated crown margin on natural tooth structure * Adequate abutment height after tooth preparation (minimum 4mm)
Exclusion criteria
* Age of patient less than 18 years old * Poor oral hygiene and calculus on sample teeth * In need of a single full-coverage crown on tooth other than a vital premolar or first molar tooth * Opposing tooth is restored with indirect restoration * Periapical or periodontal pathology * Anticipated pulp exposure or need for additional treatment (endodontic treatment, post and core, crown lengthening) * Anticipated subgingival crown margin * Anticipated crown margin on direct restoration * Inadequate abutment height after tooth preparation
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of participants with a correctly fitted prosthesis | From impression stage to crown delivery, approximately four weeks. There are no follow up visits once crown is delivered. | Correct fit assessed by clinical assessment of internal and marginal crown fit. |
