Straumann’s newly formed relationship with Createch has enabled its clinicians to utilise the whole digital CADCAM pathway.
Mr. SD attended with a previous history of some loosening teeth in the upper left quadrant. He had had a previous history of root canal treatments and recurrent infections that had required repeated courses of antibiotics. We discussed all the various options and suggested the best long term solution would be to extract the Upper Left 567 and provide 3 implant fixtures at UL457 with a simultaneous sinus floor elevation procedure and a restore with a 4 tooth screw retained bridge CAD CAM designed.
He was otherwise medically fit and well.

We extracted the teeth UL567 and allowed the soft and hard tissues to heal for 10 weeks prior to implant surgery.

CBCT evaluation revealed the need for simultaneous sinus floor elevation procedure.

4.1mm tissue levels implants were placed at Upper Left 45 and 4.8mm tissue level at Upper Left 7 with excellent fixture stability.
Fig 11 – 14 shows pictures of surgery and radiographic review
Following 16 weeks of uncomplicated healing the implant fixtures were exposed – Fig 15 – and scan bodies connected to record the intraoral position of the fixture heads – Fig 16 – and intraoral scan picture – Fig 17
Fig 18-19 show images laboratory side of CAD design pre production of the implant framework. The design is checked and approved, then requested to be milled and returned to the laboratory within 7 days.
The final prosthesis can then be CAM milled and porcelain added. Fig 20 – 21
Healing abutments are removed and any hyperplastic gingival removed – Fig 22-23
The final screw retained prosthesis is tried in situ, and the distal most abutments finger tightened first and we carefully and gradually tighten the abutments in situ little by little to each abutment. As usual contact points are checked that they remain passive and do not prevent full seating of the final prosthesis. Fig 24-26
A check radiograph is then taken to ensure the framework is fully seating. Fig 27
And the final restoration is sealed up.
The release of the implant connection design to Createch now allows us to provide a guaranteed implant abutment interface with a third party company. This in turn allows us to engage the fantastic Straumann internal taper connection and match the same alloy material for the framework.
