Esthetic treatment of a diffuse amelogenesis imperfecta using pressed lithium disilicate and feldspathic ceramic restorations: 5-year follow up.

OBJECTIVE: The treatment of a diffuse and severe case of amelogenesis imperfecta represents a challenge for the dental team and in particular for the dentist who perform the prosthetic restorations. CLINICAL CONSIDERATIONS: The enamel alterations, which are characteristic of the disease, determine different problems that need to be carefully planned and solved before the beginning of the treatment, with particular regard to the materials used to perform the restorations. In order to create the best conditions to perform the prosthetic restoration, the treatment plan should be multidisciplinary. In addition, the young age of the patients usually affected by the disease imposes a very conservative and cautious approach. The main goals of the therapy are represented by the need to protect the occlusal dental surfaces from the abrasion and provide a satisfactory esthetic result. In particular, dental abrasions if not treated may determine the loss of the vertical dimension as well as a diffuse and marked dentinal hypersensitivity. CONCLUSIONS: A correct treatment plan and the use of the new adhesive ceramic materials made it possible to obtain good results both from a functional and esthetic point of view with a much more conservative approach compared with the traditional one. CLINICAL SIGNIFICANCE: This clinical report describes the prosthetic rehabilitation of an adult female patient with a diffuse amelogenesis imperfecta using feldspathic ceramics for the esthetic regions and monolithic lithium disilicate material for the posterior areas.

Therapeutic management for post-traumatic treatment of the anterior dental region: a case report with long-term follow up.

The treatment plan represents the final step in every diagnostic procedure and is the result of a series of assessments based on information gathered from a detailed clinical history. This clinical case reports the replacement of two central incisors that were lost because of a trauma. The advantages and disadvantages of the two treatment options (i.e. implantology or prosthetic restoration) were carefully evaluated in relation to the case in hand. Patient compliance and aesthetic requirements had been also considered. In this case, a conventional prosthetic restoration was performed using a metal-ceramic bridge, utilising full crowns between the right and left maxillary lateral incisors associated with minimal canine preparation. By this strategy, the treatment plan allows for a future implant restoration, should this become necessary.

Central incisor loss after delayed replantation following avulsion: a contemporary restorative and adjunctive orthodontic management approach.

Delayed replantation of an avulsed tooth may result in rapid root resorption or, more frequently, dental ankylosis with subsequent bone substitution. If this process develop slowly, it is possible to observe that tooth loss is characterized by a well conserved alveolus with regard to bone preservation, particularly in vertical dimension. This clinical case reports a dental trauma of a central incisor in a young boy characterized by tooth avulsion and its delayed replantation. After 10 years, dental ankylosis of the incisor was recorded and the patient underwent a prosthetic-orthodontic rehabilitation using CAD-CAM technology and no-prep veneers.
