Study of Periodontal Tissues in Fixed Prostheses on Natural Teeth
Italy50 participantsStarted 2019-11
Plain-language summary
When the tooth is severely compromised, it needs a prosthetic crown. The tooth is prepared to allow the housing of the prosthetic crown without difficulty. This study aims to compare two different types of preparations to see with which of the two the gingival tissue reacts best.

Inclusion criteria
✓. Need for restoration by single-tooth prosthetic crown, due to destructive caries, coronal fracture, endodontically treated tooth, severe abrasion, aesthetic problems, remake of old incongruous prosthetic crown, other complications.
✓. If there are incongruous conservative restorations (composite fillings or other materials) in the elements adjacent to the tooth to be treated, these must be restored before the prosthetic therapy and must not be modified during the protocol.
✓. Absence of active periodontal disease
✓. over the age of 18;
✓. periodontal probing less than 4 mm in the tooth to be treated
✓. absence of bleeding on probing
✓. full-mouth plaque score (FMPS) and full-mouth bleeding scores (FMBS) \< 20% at the start of the study
✓. Patients according to protocol participation and informed consent signature.

What they're measuring
1
variation of gingival thickness
Timeframe: 12 months
2
variation of gingival thickness digital
Timeframe: The impression is taken before the final impression (t1), at 3 months (t2), 6 months (t3), 12 months (t4) and the 3D images are compared using software to evaluate the variation of the soft tissue.
