Influence of the Restorative Cervical Margin Placement on the Supracrestal Tissue Attachment

Influence of the Restorative Cervical Margin Placement on the Supracrestal Tissue Attachment. A Longitudinal Study

The aim of the present study is to understand the influence that marginal/subgingival restorations exert on the surrounding periodontal tissues. Even though proximal restorations are routine in everyday clinical practice, few information is available as to whether or not they may have a detrimental effect on the supracrestal tissue attachment.

Inclusion Criteria:

• an age range 18-70 years
• a good general health
• the ability to understand the phases of the trial and to stick to them for the whole length of the study
• the ability of will to release a written informed consent
• presence of a marginal cavity or a 2mm subgingival cavity
• presence of a cavity subgingival > 2mm

Exclusion Criteria:

• PPD>4mm
• patients affected by active periodontal disease
• patients smoking more than 10 cigarettes/pipes per day
