This step-by-step technique from Dr. Neal Patel and Marina Caponigro, MDT shows how digital tools from Sirona Dental can be used to create incredible surgical guides.
Implantology is one of the biggest growth areas in dentistry. The CEREC® and inLab® systems are an ideal way for dentists and laboratories to work closer together to create added value for their services. Dentsply Sirona’s CEREC and inLab systems continue to support dentists and dental lab technicians with their implantology cases.
To simplify the process, the two softwares work together to facilitate a joint workflow between the dentist and lab. This step-by-step case shows how we used the CEREC Guide 2 and inLab SW 15 for a completely digital fabrication of an implant surgical guide.
With CEREC Guide 2 and inLab SW 15, Dentsply Sirona provides dentists and laboratories the technology needed to expand their offering to include guided surgery. This will allow more doctors to safely place implants. Using these softwares, the clinician can communicate data with inLab SW 15 owners for fabrication of surgical guides without analog models or impressions.
The CEREC and inLab 15 SW integrate seamlessly, allowing a laboratory to create a precise surgical guide using implant data from the doctor’s implant planning.

Fig. 1 Optical impressions (a digital scan) of the case were obtained by the doctor using CEREC Omnicam and CEREC 4.4 software.
Fig 2, 2a (below) A virtual tooth (digital wax-up) was designed for the patient using the CEREC 4.4 software.
Fig. 03 The virtual wax-up design was imported as a *.ssi file and sent to the GALILEOS CBCT (cone beam computed tomography) reading workstation.
Fig. 4 The CBCT scan was acquired using Dentsply Sirona Galileos.
Fig. 05 The GALILEOS CBCT scan provides 3D diagnostic imaging for comprehensive dentistry and diagnostics.
Fig. 06 The *.ssi file from the digital wax-up was integrated within the GALILEOS implant software.
Fig. 07 The virtual wax-up was then integrated into the CBCT scan.

Fig. 11 The implant sleeve system was modified to the CEREC Guide 2 for guided surgery.
Fig. 12 A comprehensive implant plan was exported to the laboratory’s inLab SW 15 via a completely digital workflow.

Fig. 14 The material inCoris PMMA was selected as the definitive material for the surgical guide milling.
Fig. 15 The lab then trimmed the digital model for the design of the implant surgical guide directly in the software.
Fig. 16 Parameters were set for specific fit and thickness of the surgical guide.
Fig. 17 Sleeve and design tools for the surgical guide are also available to the inLab SW 15 technician.
Fig. 18 An automatic proposal of the surgical guide was then displayed in the inLab SW 15 with various tools available to modify the design (i.e. addition, removal and integration of viewing windows).
