Restoration of an Edentulous Maxilla. A Lecture by Dr. Norman Kwan
Mistakes in Implantology are bound to happen. Failures are bound to happen. “Failures are stepping stones to success” is a very true saying in oral implantology. Failures make an Implantologist. The solution is how to Minimize and Manage these problems. With every case you do, you need to understand what could be avoided to save time and become more productive.
When it comes to implant dentistry, prosthetic failures are often much more than implant failures. Screw loosening is one of the most common prosthetic failures. If you’re an Implantologist doing various types of cases, this blog post will certainly help you. Read the complete post to be able to do an edentulous maxillary implant case easily.
Dr. Norman Kwan delivered this webinar. Dr. Kwan has been very passionate about research and invention. The BioHex One-piece One- Stage Implant System results from three decades of research, innovation, and engineering.
Dr. Kwan understood the need to develop a revolutionary implant system that will be cost-effective and beneficial for all and hence got to his mission of inventing an implant system suitable to all kinds of patients.
Case of Restoration of Edentulous Maxilla with Dental Implants
Prosthesis: One-piece, Crown & Bridge, Ceramco-metallic, screw-retained & engaging restoration
Useful Tip
Be extra careful when it comes to restoration of the maxilla using multiple implants it is very
Step 1 : Abutment – The Missing Link
He used the hexagonal abutment that was developed by himself and attached it to the Branemark implant. This was an Indexed healing abutment that was incorporated onto the implant and the treatment objective was to place the abutment/ implant in the ideal position to support the planned prosthesis
Step 2: Treatment Planning- Team Communication via Abutment
List down your treatment planning and how you wish to achieve during surgery
Plan the treatment on the model so that you don’t have any room for error during the actual surgery
Prosthetic Objectives: How many Abutments would be required & Where?
Surgical Objectives: How would you want to go ahead with the surgical procedure? Goal should be to support the prosthesis by placing the abutment/ implant in the exact position as planned by the restorative dentist and the laboratory
Step 3: Pre-prosthetic procedures
AAccurately place the Implant and more accurately the Abutment
Visually verify the exact position of the abutment before you move the next step. Don’t forget to give a special attention to the gingival margin
Step 4: Healing Options
Use a Hexagonal shape Abutment as a healing abutment
Step 5: Healing Period
Use an internal hexed healing ball secured to the abutment to allow maximum gingival displacement to see a customized anatomical emergence profile
Step 6: Prosthetic Procedures
The healing ball is used as a transfer coping. This healing ball is internally hexed to allow timed transfer of hexed abutment (3-dimension)
Step 7: Final Impression
Final Impressions in the case of an Edentulous Maxilla largely depends on the Abutment placement.
These impressions determine the ultimate prosthesis.
Make sure to use Abutments with the correct geometry
Good Tip is to secure the healing ball to abutment with guide pin and employ the open tray technique
Step 8: Abutment level prosthetics
Surgically determine the Subgingival margins
Maximize gingival displacement to allow customize anatomical emergence profile
See the direct prosthetic connection at the abutment level
Step 9: Laboratory Procedures
Submit the final impressions to get a screw retained engaging prosthesis
