A Retrospective Study on Long-Term Technical Complications of Single Metal-Ceramic Crowns With a Supplementary Questionnaire Survey

This observational study aims to evaluate the long-term clinical outcomes and biological complications associated with metal-ceramic crowns. Patient dental records will be reviewed to identify eligible participants, who will subsequently be invited for a clinical examination. The clinical condition of the metal-ceramic crowns and the supporting teeth and periodontal tissues will be assessed using predefined clinical criteria. The study aims to provide information on the long-term clinical performance of metal-ceramic crowns and the occurrence of associated biological complications. Participants will also compleate a questionnaire assessing oral health-related habits and satisfaction with metal-ceramic crown.

The Effect of Fixed Dentures on Periodontal Tissues in Long-term.

The goal of this observational study is to to evaluate the periodontal condition around metal-ceramic crown. The main question to be answered is: whether the metal-ceramic crown is the cause of gum changes? The study offers to involve patients who have received single metal-ceramic crown and have kept the same tooth intact on the other side of the mouth.The condition of the gums around the crown will be compared with the corresponding natural teeth on the oposite side of the mouth. Clinical parameters such as plaque accumulation, bleeding on probing, periodontal pocket depth and gingival recession will be evaluated. All procedures are part of routine dental examination. Participants: patients who have previously received treatment with metal-ceramic crowns and agree to undergo a gingival examination.
