The outcomes of the experimental studies indicate that orthodontic tooth movement (OTM) can be performed safely for teeth with reduced periodontium, provided infection and inflammation are controlled. Orthodontic treatment can correct pathological tooth migration, is not associated with deterioration of clinical periodontal parameters and improves aesthetics. Intrusion is safe when performed with light forces and under a strict oral hygiene regimen. Teeth can be moved either towards or away from the intrabony defect previously subjected to regenerative procedures, and research suggests that OTM has the potential to enhance bone formation after regenerative therapy. The data on orthodontic movement of teeth with furcation involvement are very scarce. The improvement in furcation involvement following either combined periodontal and orthodontic treatment was only documented in animal model studies.

Teeth with non-circular canal space also require this type of restoration because the build-up with pre-fabricated posts could lead to thick cement layer. The development of CAD/CAM technologies widens the range of the materials that can be used for prosthetic restorations. Along with base dental alloys, newly developed materials may be applied. The aim of the article is to present four clinical cases of severely damaged teeth which utilize different materials and different production techniques for custom post-and-core fabrication. In the first clinical case, a metal post-and-core restoration was fabricated by direct metal laser sintering. In the second clinical case, digital technologies were used to produce a 3D-printed resin prototype for further investing and casting from base metal dental alloy. In the third clinical case, fibre-reinforced composite was used for fabrication of the custom post-and-core by milling. In the fourth clinical case, the restoration is produced by milling of lithium disilicate ceramics IPS emax CAD (Ivoclar Vivadent, Lichtenstein). The bond between the fibre-reinforced composite post-and-core and the hard dental tissues offered possibility to compensate—to some extent—the shape of the preparation which was not optimal. CAD/CAM technologies applied in these clinical cases provided combination of high accuracy of fitting with good stability and individual shape of the restorations. © 2023 Australian Dental Association.</p>","PeriodicalId":8593,"journal":{"name":"Australian dental journal","volume":"68 4","pages":"294-302"},"PeriodicalIF":2.1,"publicationDate":"2023-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/adj.12976","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10173402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Attendees were invited to complete and share a Forms survey.
