Tooth loss is a serious oral health problem that can have a significant effect on overall quality of life, making it difficult to chew or embarrassing to smile. Dental implants are a solution for people who have lost one or more teeth due to periodontal disease, trauma or injury, or other reasons. Implants are artificial tooth roots that are placed into the jaw bone and are used to support the crowns.

Dental Implant

Traditionally, a dentist will create impressions of a patient’s teeth and gums. X-ray will also be done in order to get an image of the mouth structures before placing the dental implants free hand. These technique require the dentist’s experience and expertise. Computer guided implant surgery represents a giant step forward in the replacement of teeth with dental implants.

What is Computer guided dental implant surgery?

Computer-guided implant surgery is a great advance in dental implant treatment planning. A computer program, cone-beam CT 3D X-ray and intraoral scanner will be used for planning an accurate position of dental implants. The computer program will combine x-ray images, intraoral scans and cone-beam 3D CT images and translate into a 3D model of the jaw. The dentist will be able to plan the placement of dental implants and determine their optimum position with a high degree of accuracy. A surgical guide will be fabricated by our in house 3D printer for use during implant surgery for accurate placement according to computer planning.

Benefit of computer guided implant surgery:

  1. Reduced Risks Computer-guided implant technology makes it possible to see the anatomical structures of the jaw, teeth, and surrounding tissue, thereby reducing the risks of unexpected complications during surgery as well as allowing the dentist to know exactly where the implant should be placed.
  2. Reduced Surgical Time Because a precise surgical guide is created, there is no guesswork with guided implant surgery. This allows the procedure to be completed faster than traditional dental implant surgery so patients can start the recovery process sooner.
  3. Better Patient Education Computer-guided implant technology is based on detailed scans of the oral structures. These images may be used to explain the dental implant procedure as well as to educate patients about their oral health.

Case Example: Patient of ours requesting for dental implant to replace his lower left first molar tooth.

At Prestige Dental, we are fully equipped with Cone Beam 3D CT X ray machine, Intraoral scanner and 3D printer to fabricate the surgical guides

Our new CBCT, OPG and Lat Ceph X-Ray unit
Intraoral 3D scanner available in Prestige Dental
3D printer for fabricating surgical guide available at Prestige Dental

These computers can also be a valuable tool when it comes to our explanation of how exactly your implants will be placed. The patient will be able to look at clear images, as well as ask any questions.

With the help of computer guided surgery, we able to better pinpoint the exact location within your mouth for each implant, considerably simplifying the overall procedure. As our patient, you can look forward to a less invasiveness procedure, safer with less complications, a shorter recovery time, and an overall process that is much smoother from beginning to end.

Digital crown- What is it and how does it work?

With our new Rainbow-Mill Clinic machine, we can now produce natural and functional ceramic indirect restorations (crowns, onlays, inlays) within a day!

Our miller machine!!

The creation and placement of indirect restoration is one of the most commonly performed procedures in dentistry today. Like traditional crowns and onlays, digital crowns and onlays are ideal for teeth which are badly decayed or broken and commonly used as routine finishes for procedures like Root Canal Therapy.

However, anyone who has had a standard crown or onlay done will know that it can be a time consuming process which takes a minumum of 1 week or more for it to complete.

The crown that was millerd out from the hybrid-ceramic block

Normally in the case of traditional crowns, impressions are taken and sent off to a dental lab for crown fabrication. It may take a week or two for the lab to receive the impression, make the crown and send it back to us. The waiting time and having a temporary crown in the mouth are the drawbacks of this method.

With Digital crowns/ onlays, we can shorten the entire process significantly. The biggest advantage of digital crown is that it can be designed and milled right here in our clinic. Using the latest CAD/CAM technology and state of art equipment, patients receive a perfect crown/onlay in just one day! In addition to that, the crowns are incredibly accurate as we scan your tooth instead of taking impressions.

So how does a Digital Crown work?

Your dentisty will prepare your tooth for a crown as per usual and instead of having you bite down on gooey plasticine like impression materials which are messy and uncomfortable, your tooth will be scanned with our intra oral scanner that takes a 3D image of your tooth, which is then fed into a computer programme. After designing your crown, we will use our milling machine to cut out or “mill” the exact crown that was designed out of a ceramic block. Once milled, the crown is then fitted, polished and bonded to your tooth- all on the same day.

So there you go.. now that you know about Digital crowns that can be milled (cut out) in our own clinic, you can consider giving it a go next time to save an extra visit to the clinic! Talk to your dentist about this if you have more questions or make an appointment to find out more.

Digital Smile Design

Nowadays, more and more people are concerned about their esthetic. A perfect smile can affect a person’s overall appearance, making them to have more confidence when meeting with people. Recently, Digital Smile Design (DSD) has become more and more popular, providing more predictable results for every patient.

What is Digital Smile Design

DSD is a dental treatment planning tool that helps the dental providers to have improved diagnostic vision, better outcome predictability and improved communication between the providers and patients. With DSD, the dental providers would be able to design a better and beautiful smile customized to every patient and be able to deliver the treatment planning confidently to the patients. With the patients’ complete understanding, they could perform the dental treatments efficiently.

How does DSD work?

When the patients have decided to make their smile look better, the dental providers will communicate with them to understand their expectations and needs from the treatment. Then, the providers will take photos of them and their teeth. Later, all the required photos will be imported into the DSD software.

Then, the software will help the dental provider to analyze the patients’ dental and facial proprotions thoroughly. There are various forms and shapes that can be chosen from the digital library which suits best for the patient. This gives the patients a quick glimpse into what they can expect at the end of the treatment.

Next, the providers will explain to the patients the problem lists. A thorough treatment plan is created based on the problem lists and what dental treatments are needed to achieve the final outcome. The treatment can range from simple restorative procedures, orthodontic treatment to orthognathic surgery.

Case Sample

First, patient is required to take photos of their smile.

Patient with smile
Patient with retracted smile

Next, photos are imported into the DSD software. The providers identify the patient’s smile issues. Then, the software is used to analyze their dental and facial proportion, thus designing a better smile design customized to every patient.

Patient’s smile design
Patient’s close up smile design
Patient’s smile design simulation

Lastly, the final outcome of the smile design is then displayed on the software. Treatment plan based on the design is then discussed with the patient.

What makes DSD unique?

After smile design simulation

Although digital imaging and diagnostic mock-up can show to the patients how will they look like at the end of the treatment, they have their limitations in terms predictability. With DSD, the providers are able to tell the patients exactly what their smile will look like because final outcome of the patient’s smile will be displayed in the software and the accuracy of the the final outcome is high. With these, miscommunication between the patients and providers can be avoided as they will be on the same page.

Who is a best candidate for DSD?

Good news is everyone is a good candidate as long as they want to have a better and beautiful smile.

So, if you have always wanted to do something about your smile, this is the opportunity to bring up your wants and needs.
