Guidedimplantsurgerykit In order to use a surgical template for guided surgery,aspecialdrillkitmustbeused.Surgicaltem- plates and implants vary from one manufacturer to another, and various guided surgery kits are avail- able on the market. Therefore, the manufacturer must advise which surgery kit is to be used with its surgical template. _Case report A 56-year-old partly edentulous female patient presented to the clinic for evaluation of options for an implant-borne prosthetic reconstruction of the mandible. The general anamnesis did not find any noticeableproblems,andthepatientwasnotonany regular medication. The clinical examination found severe periodontal destruction around the remain- ing teeth in the mandible (probing depth of 6mm) and an adequately supplied maxilla. In order to estimate the status of the alveolar bone and to evaluate implant surgery options, a 2-D radiographic examination was recommended and, consequently, carried out using the 2-D function of aCBCTdevice(SCANORA3D,SOREDEX).Apanoramic radiograph was acquired to confirm the primary diagnosis of severe chronic periodontitis and to reassess the need for further radiographic proce- dures(Fig.2).Thepatientwastheninformedabout the diagnosis, therapeutic options and respective approximate costs. Implantplanningprocedure The patient elected for implant-borne pros- thetic reconstruction of the mandible. A CBCT scan was consequently acquired (SCANORA 3D) to per- form software-based implant planning for guided Fig. 2_Panoramic radiograph. Fig. 3_Radiographic guide and radiographic guide index in situ.
