Delivering results with digital dentistry


Digital dentistry technologies have proven themselves and should be a cornerstone of every dental practice, said Dr Mohamed Hassanien, who set up the CAD/CAM department at the faculty of dentistry in Misr International University in Cairo, Egypt.

With CEREC Primescan and Primemill, dentists can deliver high quality and fully glazed zirconia restoration in under 30 minutes. CEREC technologies can also be used to design restorations, plan implant positions and mill a surgical guide chairside to ensure precise implantations.

Furthermore, by tapping both CEREC 5.1 and inLab 19 software, dentists can design mock-ups to minimise tooth preparations and guarantee a fully predictable outcome. The mock-ups can also be shown to patients before treatment.

Even for multi-layered implant abutments with an upper supra structure and a lower abutment part, the software can split the design into two parts.

 “The dentist will be able to manufacture a precise and accurate implant restoration that is bonded on the titanium base extra orally without any risk of excess cement escape in the patient’s mouth,” explained Dr Hassanien.

He noted, “Implementing digital workflows into implant dentistry enables clinicians to design implant restorations with the highest degree of precision and accuracy.”

While adapting digital dentistry technologies will involve a learning curve, many established products such as CEREC and inLab are easy to use and have user-friendly interfaces. Training facilities and online educational websites are also widely available.

Dr Hassanien said digital dentistry technologies, with their ability to scan patients’ teeth with high accuracy, will be especially useful for chairside restorations, which take up less time and are less prone to errors compared to lab-fabricated restorations.

“The only thing is that dentists must have a thorough knowledge of different materials’ characteristics, to be able to select the most suitable material for each case and maximise aesthetics and function,” he said.

He summarised, “Today, precise planning with digital tools will ensure that clinicians get the results they need in implantology as well as restorative dentistry. For patients, the tools will give them their smile back and have a great, positive impact on their day-to-day lives.”

Dr Hassanien will be holding a conference session titled “Today’s Innovation, Tomorrow’s Reward – Implementing Digital Dentistry in your Clinic” at the digital edition of the International Dental Exhibition and Meeting (IDEM) 2020 on 8 July, 20:00 – 21:00 SGT (GMT+8).


About Dr Mohamed Hassanien

Mohamed Hassanien graduated with a bachelor of science degree in dentistry from Misr University for Science & Technology in Egypt in 2002. He graduated with a master of science degree in fixed prosthodontics, faculty of dentistry – Cairo University in 2008.  Later in 2011, he completed his PhD degree in fixed prosthodontics from Cairo University.

Dr Hassanien established the CAD/CAM department in faculty of dentistry in Misr International University (MIU) in Cairo in 2018 both for CAD/CAM chairside and lab side workflow, where undergraduate students and postgraduate students are doing their research work and faculty requirement is under his team supervision. Each year he spends a considerable amount of time helping postgraduate students doing their research work on CAD/CAM workflow and evaluating ceramic restorations. He became an ISCD Certified Trainer in 2011, until this present time. He has been a CEREC user for 10 years, offering patients all ceramic, high aesthetic restorations fabricated and delivered at the same appointment.
