All on 4 Dental Implants

Full-arch rehabilitation with only four implants

Below we follow a step by step guide to produce an all on 4 porcelain bonded to non-precious metal bridge, with Dr Ania Heer and MediMatch Dental Laboratory.

STEP 1 (1st Surgery visit)

  • Take full arch silicone primary implant level impression and an opposing.
  • Send impressions to the lab.

STEP 2 (In Lab)

  • Cast the impression.
  • Mount models in articulator using the bite enclosed.
  • Fabricate porcelain bonded to non-precious metal crowns on 46 and 36.
  • Fabricate porcelain bonded to non-precious metal bridge on cement retained implants on 16 15 14 13 12 11 21 22 23 24 25 26.
  • Fabricate metal substructure framework. The framework is designed to go over the direct abutments on 24 26.
  • Fabricate removable crowns around the implant areas to access the screw.
  • Add pink porcelain where needed.
  • Sent pictures of Pre-Glaze stage to Dr to approve.

STEP 3 (2nd Surgery visit)

  • Fit everything in the patient, ensure passive fit.
  • Take a radiograph to ensure everything fits well in the patient mouth.
  • Check that the occlusal contact and shade are correct.


  • Very high in aesthetic
  • Natural looking
  • They are designed much like the traditional crown and bridge style
  • They last a long time and continue to look good for a long period
  • They can be customized to fit just about any style


  • They can be expensive and require a skilled and experienced provider to ensure the best results
  • If there is damage or a break occurs, it can be difficult to repair
  • They are heavy when compared to an acrylic all on four denture
  • It will not be suitable if the opposing arch is an Acrylic denture or zirconia crown/bridge as they will speed up rate of wear in the opposing arch

We accept analogue and digital impressions from all scanners!
