Digital work-flow.

OBJECTIVE: The project presents a clinical case in which the digital work-flow procedure was applied for a prosthetic rehabilitation in natural teeth and implants. MATERIALS: Digital work-flow uses patient's photo for the aesthetic's planning, digital smile technology for the simulation of the final restoration and real time scanning to register the two arches. Than the scanning are sent to the laboratory that proceed with CAD-CAM production. RESULTS: Digital work-flow offers the opportunities to easily speak with laboratory and patients, gives better clinical results and demonstrated to be a less invasiveness method for the patient. CONCLUSION: Intra-oral scanner, digital smile design, preview using digital wax-up, CAD-CAM production, are new predictable opportunities for prosthetic team. This work-flow, compared with traditional methods, is faster, more precise and predictable.

Implant surgery and oral anticoagulant therapy: case report.

OBJECTIVES: This work aims to assess the risks both thromboembolic that bleeding of a management protocol "non-conservative" in patients on oral anticoagulant therapy (OAT) to be undergoing implant surgery. MATERIALS AND METHODS: We decided to take a surgical "non-conservative" protocol, to insert four implants in the aesthetic zone, without using flapless surgery and the surgical template. In accordance with the hematologist, the value of INR is lowered and warfarin was replaced with heparin low molecular weight, to have a better coagulation's control. RESULTS: The modern guidelines impose a protocol of conservative management in patients with OAT, with minimally invasive surgery, flapless, and use of surgical template to reduce the risk of uncontrolled bleeding. This, thanks to the team-work between dentist and hematologist, thanks to careful adjustment of INR and the use of local haemostatic agents, were not encountered any problems with bleeding or intra or postoperative. CONCLUSION: Surgical treatment of patients with OAT is a real problem for the oral surgeon, to treat every time in association with the hematologist. Applying this type of surgical procedure, different from today's guidelines, in our experience there were no post-operative complications (bleeding or bleeding); osseointegration has not been compromised and the prosthetic rehabilitation was completed successfully.
