Immediate implant – CAD/CAM supported implantology

Individual abutment design and soft tissue preservation during treatment with the immediate implant

Despite being informed about the possible risks and insufficient long-term experience, the patient decided to use the Replicate-System immediate implant.

The minimally invasive surgical intervention and maximum preservation of the tissue structures of the anterior region were regarded as the main basis for the decision.

Acquisition of the natural tooth:

With root-analog implants, the replication of the root geometry is carried out by means of a 3-D acquisition of the tooth before its extraction by means of digital volume tomography. Here, advances in digital technology make it possible to link intraoral scan data or STL data indirectly obtained by scanning the master model with digital volume tomography imaging.

On the basis of both data formats, the immediate implant with the abutment can be manufactured CAD/CAM supported prior to surgery.

Condensation of the autologous bone chips:

To counteract resorption of the bundle bone, the buccal part of the alveolus was augmented with sufficient autologous bone chips. These can be obtained carefully with twist drills of common implant systems without water cooling and at low rotation (< 80 rpm) in the apical-palatal direction.

Without augmentative measures, tissue structures can regress because the so-called bundle bone resorbs after tooth removal. Simultaneous augmentation measures are necessary to maintain the osseous support for the soft tissue. At the same time, the immediate support of the soft tissue through individual abutment design is a decisive success factor.

Tapping into the correct position was done with a prefabricated insertion aid.
