Title: Multidisciplinary reahabilitation of a patient with bruxism- Clinical case
Prosthetics: : NobelProceraTM zirconia crowns
This clinical case refers to a 69-year-old male patient who came to MALO CLINIC Lisbon complaining of an inability to chew properly and aesthetic concerns.
Thorough clinical and radiographic analysis revealed: multiple missing teeth; posterior bite collapse associated with reduced vertical dimension; altered interocclusal space; teeth with generalized wear and attrition; altered tooth position and multiple diastemas. Anamnesis reported parafunctional dental habits (grinding and clenching).
The vertical dimension of occlusion and maxillomandibular relationship were restored with an anterior jig.
The treatment plan also included multiple extractions (18,28,38,48)*, NobelSpeedyTM Groovy implants placement (24,25,35,36,45,46,47)* and endodontic treatments (16,15,14,13,12,11,21,22,23,26,33,34,41,42,43,44)* followed by reconstruction with D.T. Light-Post®(Bisco Inc.; Schaumburg, USA) and rehabilitation with provisional crowns.
The treatment was concluded with the cementation of NobelProceraTM zirconia crowns, over teeth and easy abutments (NobelBiocare ® USA, LLC, Yorba Linda , CA), all done with GC Fuji PlusTM (GC, América, Inc.).
The restoration of a correct vertical dimension in cases like this is the key aspect to success in the rehabilitation of patients with parafunctional habits.
At the 3,5 year follow-up, the only complication observed was a root fracture in tooth 14*, with subsequent extraction and placement of a NobelProceraTM zirconia crown over an implant.
