Guided Implant on a Tricky Crest – clinical case

Dott. Alexandre Minis, France

Patient is a 56 years old male without a previous medical history. Tooth # 36 has been missing for several year.
Despite a satisfactory bone height on the panoramic, the CBCT reveals a thin bone at the level of the crest which does not allow the available height to be exploited.
In order to obtain an ideal prosthetic axis and to use the available bone to the maximum, the surgery is performed using a surgical guide, design on 3Shape Implant Studio, a classic dentition supported guide, 3D printed on a Phrozen Shuffle printer.

An EL (4.3mm * 9mm) was placed very subcrestal, but part of the lingual bone was removed and then grafted vestibularly under a collagen membrane.
The bone was dense and satisfactory primary stability was easily achieved.
A long healing abutment (5.5mm * 6.0mm) was then placed.
The patient will be seen again at 3 months for the final crown.
