Missing back teeth; lack of bone and gums
All-on-4 implant with gum replacement
Decayed teeth; excessive wear
Unlike removable dentures, All-on-4 dental implants are a permanent solution for a healthier smile for life.
“All-on-4” lets you replace your dentures straight away, without the lengthy procedure for conventional implants.
With All-On-4 implants, the technique involves inserting the two front fixtures straight in the front of the jaw, while the two back implants are inserted at a 45° tilt to provide the required stability and support for immediate fixed replacement teeth. The titling of the back implants also helps overcome bone deficiencies often found in the back of the jaws thereby improving safety and reliability, as well as in most cases avoiding the need for bone grafting.
At your complimentary consultation, your dentist will discuss your treatment goals and options, along with the advantages and disadvantages of each one.
This part of the process is an important one, to ensure both you and your dentist have aligned treatment goals and expectations.
To prepare your new smile, a 3D cone beam scan is generally taken at this visit along with dental impressions and/or a 3D digital scan of the teeth and face.
These scans and impressions are used to fabricate a surgical template for use on the day of surgery by the dental surgeon.
To make sure your new smile is right for you, you’ll get to trial your smile to see how your smile looks, how your bite feels and how your speech sounds.
From here, we can tweak your smile if we need to, ensuring your final smile is just right.
Before the implants are put in, each point of insertion will be marked on the surface of the bone. Then, the dental surgeon drills pilot holes in the implants at precise angles to give them the most stability and strength while preventing sinus cavities and nerve canals.
When the dental implants are in place and properly secured to the right torque, the dentist will replace the gum tissue around the implants and close the incision area. At this point, the abutments holding the replacement tooth prosthesis get attached to the implant interface.
The final phase of treatment involves the installation of the all on 4 ‘bridge’. The replacement teeth are inserted on to the implant abutments and tightened with a torque wrench to ensure that there has been sufficient preload on the abutment screws.
The screw access holes are then filled and sealed. It is important to confirm the bite is evenly occluding. The restorative dentist will correct any premature interferences to ensure proper upper or lower jaw occlusion.
