Why Milling Is Better Than Injection Molding for Ceramic

Dental Implants

​

When it comes to dental implants, the manufacturing method directly affects quality, strength, and biocompatibility.

Here's why our  CNC milling is the superior choice over injection molding:

 

 

 

 

 

 

 

Material Integrity

Higher Precision and Dimensional Accuracy
CNC milling enables extremely precise manufacturing with micrometer-level tolerances. This is crucial for implants that require exact fit and alignment (protolabs.com).

 

Dimensional Precision

CNC milling achieves micron-level tolerances, enabling precise implant geometry for optimal fit and function.

Injection molding suffers from shrinkage and distortion during sintering, leading to variable accuracy and the need for post-processing.

 

Surface Quality

Superior Surface Quality
Milled implants can achieve excellent surface finishes, which is beneficial for osseointegration and soft tissue adaptation (pmc.ncbi.nlm.nih.gov).

 

No Additives or Contaminants

Milling uses pure ceramic blocks, eliminating the need for binders or plasticizers.

Injection molding relies on organic additives, which must be burned out—risking residue or incomplete removal, which can affect biocompatibility.
