The accurate transfer of the subgingival contours of implant-supported restorations and pontics is essential for providing the dental technician with the necessary information to fabricate an optimal definitive fixed dental prosthesis. However, once the interim restoration is removed to make an impression, the subgingival tissue, which is no longer physically supported, tends to collapse. This digital intraoral and extraoral scanning technique offers a way to transfer the subgingival contours and intaglio surface of the interim restoration to the definitive restoration. In addition, this technique can reduce clinical and laboratory time, as well as the necessity of storing gypsum casts.

This case report features a female patient with the chief complaint of needing to replace an anterior crown. After a comprehensive oral assessment and cone beam computed tomography (CBCT) radiographic examination, it was determined that the crown on Tooth #9 was subgingivally fractured. The procedure involved atraumatic extraction of Tooth #9, followed by immediate implant placement.

Clinical crown lengthening is a surgical procedure that involves the manipulation of gingival tissue, designed to expose sound tooth structure for restorative purposes by apically repositioning the gingival tissue, with or without the removal of alveolar bone. Crown lengthening may be subdivided as functional or esthetic, according to the purpose of treatment. Functional crown lengthening pertains to the exposure of subgingival caries, fractures, or to avoid invading the biologic width.

The esthetics of immediate implant dentistry can be challenging. Clinical considerations for immediate implant placement have demonstrated long-term success rates comparable to traditional delayed implant protocols. However, it is a sensitive technique that requires proper treatment planning as well as meticulous execution to be predictable and successful in the long term.

Article Synopsis
- * A biologically oriented vertical preparation technique moves the gingival margin and modifies provisional restorations to improve tissue healing and establish long-term stability.
- * Effective communication about the design of temporary restorations is crucial to prevent complications in the final restoration process, which can increase time and costs in clinical and laboratory settings.
Despite the clear advances regarding the restoration of posterior teeth, especially with the minimally invasive approach, there are still several topics where the available scientific evidence does not provide clear answers in terms of clinical decisions. The indications, differences, and clinical protocols for partial adhesive restorations (onlays, overlays, and endocrowns) and resistance form restorations (full-contour resistive crowns) were presented in Parts I and II of the present article series based on Coverage of susceptible cusps, Adhesion advantages and limitations, Resistance forms to be implemented, Esthetic concerns, and Subgingival management - the CARES concept. Now, in Part III, the focus is on different approaches of managing subgingival areas, gaining "ferrule" design, and the role of posts on the restorability strategies of severely compromised teeth.
