inal answer:
An autogenous connective tissue graft is indicated for a maxillary canine receiving a full crown with subgingival margins when there is only 1mm of attached gingiva, to prevent impingement on the biological width.
Step-by-step explanation:
Which of the following periodontal procedures is indicated on a maxillary canine that will receive a full crown with subgingival margins when the abutment has 1mm of attached gingiva, with no sign of inflammation or loss of attachment? The correct answer is D. Autogenous connective tissue graft. Since the abutment tooth has only 1mm of attached gingiva, which is less than the desirable amount for health and stability, a connective tissue graft would be indicated to increase the width of attached gingiva prior to crown placement. This would ensure that the subgingival margins do not impinge upon the biological width, which is important for maintaining periodontal health.
The abutment has 1mm of attached gingiva and no sign of inflammation or loss of attachment. In such cases, the periodontal health is stable and does not require any additional periodontal procedures.
