Combined treatment with laser sintering and zirconium: a case report of dentinogenesis imperfecta.

[dentinogenesis imperfecta]

Osteogenesis imperfecta (OI ) is a heterogeneous disorder of connective tissue that manifests mainly as skeletal deformity and bone fragility . Dentinogenesis imperfecta (DI ) is sometimes an accompanying symptom of OI . The treatment protocol of these patients varies according to the clinical appearance . The case report here describes complete mouth rehabilitation of an 18 -year -old male patient with OI and DI using direct metal laser sintering (DMLS ) technique of metal-ceramic restorations and zirconium all-ceramic crowns . DMLS is an additive metal fabrication technology that is simpler , more precise , and healthier than conventional manufacturing and can be remarkably cost effective . Moreover , the technique affords highly accurate production of fixed partial dentures with ideal marginal fit and excellent mechanical properties . The patient was treated using a multidisciplinary strategy that focused on controlling caries , protecting teeth from further wear , obtaining an appropriate vertical dimension , and providing soft tissue support to return the facial profile to a normal appearance using new technology in the field of prosthetics .
