Minimally invasive rehabilitation of an extensively damaged vital tooth using the CAD/CAM system

Objective: The restoration of vital teeth with extensive loss of coronal structure is a challenge for modern dentistry. The most common treatment for this type of case is the use of mechanical retention through the use of intraradicular retainers such as glass fiber posts after endodontic therapy, followed by the fabrication of an indirect restoration. However, more recent approaches have proposed more conservative treatments, due to advances in Adhesive Dentistry combined with the use of minimally invasive preparations, which prevented a reduction in the fracture resistance of dental remnants. Methods: This article describes a clinical case report involving the rehabilitation of an extensively damaged vital tooth. A 63-year-old female patient, on clinical and radiographic examination, an extensive coronary fracture of dental unit 17 was found without pulp and/or periodontal involvement. Results: A minimally invasive indirect restoration was performed with a lithium disilicate fabricated with the CAD/ CAM system in a single visit without the need for additional wear and especially without the use of intracanal post. The proposed treatment was followed up for 2 years and showed good evolution. Conclusion: Minimally invasive indirect restorations fabricated with the CAD/ CAM system combined with an adequate adhesive technique are an effective, conservative and aesthetic alternative to restore extensively damage vital posterior teeth.
