Riccardo Tonini
: The case of a nineteen-year-old female with atypical fractures to three maxillary incisors (#11 FDI, #8 universal; #21 FDI, #9 universal and #22 FDI, #10 universal) with one showing a complicated crown fracture and pulp exposure is reported. A partial pulpotomy had been carried out immediately after trauma and the patient complained of acute pain on percussion of the left central incisor. Direct restoration with resin-based composite was carried out on the two teeth where fragments were not available (tooth #8 and #10) and root canal treatment with reattachment of fragments and fiber post was carried out on the third (tooth #9)...

OBJECTIVE: Extraction-socket resorption is considered a major problem that can limit implantological rehabilitation options and compromise the esthetic outcome. Surgical techniques to reduce remodeling are of restricted predictability and commonly require several surgical interventions and grafting. This increases the treatment cost and places a physical and psychological strain on the patient. This clinical case report presents a replacement of an upper canine using the socket-shield technique (SST) with a CAD/CAM surgical guide, resulting in a predictable, high esthetic, and functional result...

OBJECTIVES: Successful orthodontic treatment presupposes that the esthetic and functional outcomes are maintained. Bonded retainers on the incisors and canines provide this stability. Failure of one or two units exposes the teeth to a relapse. This article describes the use of a retainer wire and an elastic device to provide rapid, effective and esthetic correction of incipient crowding. CLINICAL ASPECTS: After removing the retainer, a fixed appliance comprising a replacement retainer and a clear elastic are positioned...

OBJECTIVE: Therapeutic options for dental trauma depend on the injuries' features. For patients with uncomplicated tooth fractures, adhesive materials and composite partial veneers may be a therapeutic solution that completely preserves healthy tooth structure. CLINICAL CONSIDERATIONS: An ultra-conservative approach, using indirect composite partial veneers to restore fractured anterior teeth is described in these case reports. CONCLUSION: Despite the position of the finish line in the middle of the clinical crown, this solution offers functional and esthetic outcomes using an indirect composite technique, and appears to be a suitable alternative to direct composite restorations or less conservative indirect veneers...
