All on 4 dental implant technique – Temporary bridge

After multi-unit abutment fixation in All on 4 dental implant technique, jaw bone print is taken. Inter-jaw data is determined so that our dentist could successfully make temporary All on 4 dental implant bridge.

First few hours after the procedure patient needs to try temporary bridge to outlay shape and size of teeth. The next day temporary bridge is being fixed on the implants. So the first phase of all on 4 dental implant procedure is finished.  Temporary bridge is made of acrylic and you will wear it for next six months – that is why it is called temporary.

How to maintain new teeth?

Hygiene and cleaning is specific and differs from cleaning techniques of natural teeth. Dental bridge consists of one piece and has no space between teeth. It needs to be cleaned as a one unit. All available surfaces of the bridge must be cleaned with toothpaste. Another step is cleaning the areas around the implants with oral shower (Waterpik or Philips Airfloss). It can reach the basal side of the bridge that is connected to the gums. Likewise, in dental implant care it is important to regularly use dental floss. Use it to clean even more space between gums and bridge. Also, use mouthwash that does not contain alcohol, to disinfect oral cavity.

We advise patients to book regularly check-ups. We do so in order that dental bridge can be removed and professionally cleaned and polished.

All on 4 dental implant technique – Planning

The All‑on‑4 dental implant technique was designed to restore the back (posterior) sections of the jaw, where bone resorption and nearby anatomical structures can make traditional implants challenging. When there isn’t enough bone to anchor the implants securely, we first carry out a bone‑augmentation procedure to create the necessary volume and stability.

In the All‑on‑4 technique, the two front implants are inserted vertically in the middle of the jaw, while the two back implants are angled 30–45 degrees so they emerge in the region of the second premolar. This tilted placement lets us bypass vital structures—the maxillary sinus in the upper jaw and the mandibular nerve in the lower jaw—while still providing strong support for the final bridge.

The procedure begins with a 3‑D CBCT scan of your jaw to guide precise planning. This scan lets us position the implant accurately, matching it to the bone’s volume and density. We must also achieve primary stability which comes from pairing the implant’s length, shape, and surface with the quality of your bone. When these factors align, we can place a temporary implant‑supported bridge within 24 hours.

We use Nobel and Neodent dental implants.

All on 4 dental implants durability

Finally, dental implants after placement and recovery go through the process of osseointegration. It is a process when dental implants become part of your body and remain permanently in the jaw bone. Even though dental implants is a solution for life sometimes dental bridge on the implants itself needs to be changed due to changes on the surrounding tissue but that is an exception, not the rule.

All on 4 dental implant technique – Permanent bridge

How long does my jaw need to heal before the permanent bridge?

Once the dental implant placement is done, patient waits for 6 months. Afterwards, dental bridge is being made. This period of 6 months is necessary for the jaw tissue to become stable.

What happens after we take the temporary bridge off?

The change from having a temporary bridge to having a permanent one is easy and painless. After removal of temporary bridge we take the imprint of the jaw bone.

Do I have teeth while making the permanent bridge?

Yes, in the meantime, while the permanent bridge is being in process, patient wears temporary bridge. We have to make sure in this period that everything fits perfectly. So we need this time to make the final adjustments. But that does not affect your eating and smiling. You can still do everything with the temporary teeth.

How is that metal or zirconia framework manufactured so precisely?

Dental bridge connects together with dental implants. Bridge construction has holes to hold the screws. The construction is made out of metal or zircon. Model is made and gets digitalized by scanning procedure. After that construction is computerized. Metal construction of the dental implants is made using 3D printer. This technique provides probably most accurate structure without internal tension of metals. Also, metals are formed by the classical casting process due to large thermal oscillation. Zircon construction is obtained by zirconia ceramic block.

Why choose ceramic (porcelain) permanent bridge?

Unmatched translucency and polish for a truly natural smile. When porcelain is layered on zircon, light travels through the ceramic layers, giving a subtle 3‑D color spark that looks just like real enamel.
