The Dual-Guide Technique

Utilizing two guides for efficient implant placement and immediate loading

The patient is a 35-year-old man, suffering from severe medical conditions that contraindicate any open-flap surgery.

In 2014, he fell and badly injured teeth 12-11-21.
At that time, to prevent surgery, root canal treatments were performed in these teeth and they were restored with crowns.
At the end of 2020, he complained that teeth 12-11 were not stable, and felt "funny".
In a radiograph it was obvious that teeth 12-11 suffer from external resorption.

It was clear than that there is no way but to extract teeth 12-11.
Under strict medical supervision, the two teeth were extracted, and he received a temporary partial denture which he did not like, and therefor asked for a fixed solution.

After three months of healing, a CBCT of the area was obtained.
The ridge at the site was slightly resorbed, and the crestal width measured 4-5mm.
Due to his medical condition, and in order to avoid open-flap surgery, Adin's guided surgery was used.
Two Adin Touareg CloseFit™ NP 3.0mm were planned to ensure maximum bone surrounding the implants, A secondary prosthetic guide, with two provisional crowns was also planned, to perform immediate loading at the time o f implant placement.
On follow-up visits it was obrious that the gingival tissues were healed appropriately, restoring form and function of the treated area.
