abutment margin 0.5 mm subgingival
when fabricating an abutment to support the crown, the margin will be placed 0.5 mm below the gumline
Device: abutment margin 0.5 mm subgingival
abutment margin 1.5 mm subgingival
when fabricating the abutment to support the crown, the margin will be placed 1.5 mm below the gumline
Device: abutment margin 1.5 mm subgingival
- Number of Participants With Abutment Margin Exposure > 0 [ Time Frame: up to 6 months post surgery ]Margin exposure of the abutment between groups at 6 months post surgery.
- Number of Participants With a Soft Tissue Response of Bleeding [ Time Frame: 6 months post surgery ]To assess the condition of the peri-implant mucosa, those with a soft tissue response of bleeding upon probing were counted. Fisher's exact test will be used after the site has been evaluated for presence of bleeding or not.
- Number of Participants With Provisional Crown Fit at Delivery [ Time Frame: 8 weeks post surgery ]To assess if the Provisional Crown was able to be cemented at time of abutment connection was reported as 'Yes' or 'No.'
