Dr. Hawryluk performs BioHorizons guided implant surgery at his Mississauga Dental Clinic. This is a highly predictable and successful technique for implant placement.
Guided implant surgery is the process of planning the dental implant surgery on a computer using the patient’s CT image. Patients often find the recovery and the actual appointment for placing the implants much better than they expected. The key to this technique is the detailed planning that Dr. Hawryluk does prior to placement in conjunction with the radiologist. Guided implant surgery is especially helpful in areas where there is minimal bone available, multiple implants are to be placed, and circumstances where there are issues with proximity to nerves in the jaw. These situations can be carefully planned for implant placement with the BioHorizons Guided implant protocol. A fully guided implant protocol is critical for ensuring the highest probability of success. Guided implant placement is superior in every measurable parameter of implant placement compared to a ‘freehand’ method. This includes higher quality in implant depth, placement, angulation, and the fit of the dental crown which will eventually be fit on top of the implant.
Dr. Hawryluk will assess whether a guided implant approach will work in your situation. One of the variables determining this will be whether or not there is adequate vertical space in your mouth available for the guided implant drills. After the initial assessment is complete Dr. Hawryluk will order a CT from Canaray Radiology. Their Mississauga location recommended as it is relatively close to St. Lawrence Dentistry, has Saturday business hours, and is a ‘walk in’ center.

We will inform the radiology center if a guided surgery approach is being considered for your planned dental implants and they will scan all the indicated areas with this in mind. In particular, they will also scan the teeth opposing the implant area so that the eventual implants can be planned in such a way that they line up ideally as possible with your opposing teeth. Once the diagnostic image is obtained Dr. Hawryluk will make a digital wax of your tooth replacement. Whenever possible your implant will be designed so that the forces of the opposing tooth will be down the long axis of your implant. All this information collected will ensure the highest predictability of your implant placement.
There are general parameters which Dr. Hawryluk will consider when planning your dental implant. In general, the minimum tooth to adjacent implant distance should be 1.5mm. This protects tooth health and prevents soft tissue encapsulation of the implant. This minimum distance will help preserve the papilla (interdental gum) between implants and teeth. For anterior (front teeth) implants we want them canted in a slightly ‘lingual’ emergence in a ‘buccal/lingual plane’ (buccal means toward the cheek and lingual means toward the tongue). In addition, for anterior (front teeth area) implants, at least 2mm of buccal bone should be preserved when making the space for the implant. This can really minimize any chance of gum recession around these implants. Implants in this area should sunk 3mm below the facial (toward the lips) zenith of the soft tissue. The minimum implant to implant distance should be 3mm (at least for non-platform switched implants). ‘Platform switching is whenever an abutment is used that is smaller in diameter than the implant platform. Platform switching can help prevent bone loss, which is fundamental for the implant’s long-term success and stability. It can also increase the volume of soft tissue around the implant, helping to improve the esthetic end result. Finally, implants are generally placed over the ‘ridge’ area of bone and are canted slightly ‘lingual’ in a ‘buccal/lingual’ direction.
In about 3-4 weeks following your CT scan, the results will be ready and Dr. Hawryluk will review the CT scan findings. At this point, an accurate estimate for the implant procedure can be made. We will make a time for Dr. Hawryluk to review the implant procedure with you.
If you elect to proceed with the implant placement Dr.Hawryluk will then have an online planning session with the radiology center to decide on the position of your dental implants. Upon completion of the meeting, the radiology center will fabricate a surgical guide using the virtual treatment plan and BioHorizons master cylinders and pilot sleeves. In addition, a detailed patient-specific surgical protocol is generated by the radiology center for Dr. Hawryluk to follow. This implant guide typically takes the radiology center about a week to make.
Finally you are now ready to have your implants placed by the most precise and advanced method possible. Dr. Hawryluk will use the surgical guide and the BioHorizons guided surgery kit while following the carefully planned surgical protocol.
