Prospective Clinical Evaluation of Periodontal Response to Different Prosthetic Margin Design
Sub-gingival margin placement is sometimes required due to different reasons and is often associated with adverse periodontal reactions. The purpose of this study was to determine if a single restoration with subgingival margin on a tooth, in the maxillary anterior zone, would affect its periodontal...

Sub-gingival margin placement is sometimes required due to different reasons and is often associated with adverse periodontal reactions. The purpose of this study was to determine if a single restoration with subgingival margin on a tooth, in the maxillary anterior zone, would affect its periodontal soft tissue parameters, and whether or not a deep chamfer preparation has a different influence in the periodontium when compared to a feather edge preparation. Plaque and gingival indexes, periodontal probing depth, bleeding on probing and patient’s biotype were registered. 106 teeth were prepared with a deep chamfer, while 94 were prepared with a feather edge finishing line. Six and twelve month after the restorations delivery the same parameters were evaluated. Repeated measure one-way analysis of variance (ANOVA ) (α=0.05) was used. At six months the patient A statistically significant difference between baseline and the 6 and 12-month follow up is present in regards to plaque index, gingival index and periodontal probing depth, but no statistically significant difference between chamfer and feather edge finishing lines. There is a statistically significant difference between baseline and the 6 and 12-month follow up in regards to bleeding on probing. Feather edge preparation presents significantly more bleeding on probing and less gingival recession than the chamfer. Sub-gingival margins do influence the periodontal soft tissue response. Statistically significant difference exists between feather edge and chamfer finishing lines in regards to bleeding on probing and gingival recession. Subgingival margins should be carefully selected, especially when feather edge finishing line is utilized. |
