Dental implant types - the typical substrate they start from - the key finishing challenges - and when wet blasting can help...

Endosteal 
• Typical substrate: CNC-machined titanium rod / bar (commercially pure or Ti alloy); less commonly zirconia from a ceramic block 
• Finishing issue: CNC tool marks + micro-burrs; coolant/oils; possible retained grit/residues after blasting 
• Wet blast: Final clean + gentle deburr + uniform matte/microtexture; good flushing of threads / undercuts.

Subperiosteal 
• Typical substrate: Additively manufactured (powder-bed fusion) titanium, sometimes with machined interface features 
• Finishing issue: Trapped powder/partially fused particles; high as-printed roughness; support scars; hard-to-reach crevices 
• Wet blast: Excellent for depowdering/cleaning complex geometry; helps level to a more uniform finish.

Transosteal 
• Typical substrate: CNC-machined plate/screw components; often titanium alloy in classic “staple” designs (some variants reported in other alloys) 
• Finishing issue: Sharp edges / burrs; crevices trap residues 
• Wet blast: Edge conditioning and cleaning without dry-blast dust; useful for flushing crevices.

Zygomatic 
• Typical substrate: CNC-machined extra-long titanium implant blank (commercially pure Ti or Ti alloy) 
• Finishing issue: Long threads increase residue retention risk; consistency over full length 
• Wet blast: Thorough cleaning / flushing and consistent conditioned finish along long threads.

Pterygoid 
• Typical substrate: CNC-machined long / angled titanium implant blank (commercially pure Ti or Ti alloy) 
• Finishing issue: Long/angled geometry complicates cleaning; micro-burrs can persist 
• Wet blast: Controlled deburr and cleaning in complex thread forms / recesses.

Narrow-diameter / “Mini” 
• Typical substrate: CNC-machined titanium alloy rod/bar stock 
• Finishing issue: Sensitive to over-finishing (feature rounding/thread damage); needs gentle, repeatable finishing 
• Wet blast: Process-controlled cleaning / deburr with a controlled matte finish.

Short implants 
• Typical substrate: CNC-machined titanium rod/bar (commercially pure Ti or Ti alloy) 
• Finishing issue: Less surface area means tighter control of final surface state; dense threads can retain residues 
• Wet blast: Consistent cleaning / conditioning, especially for dense threads.

One-piece 
• Typical substrate: CNC-machined titanium from rod / bar, or zirconia milled/ground from a ceramic blank
• Finishing issue: Harder to zone-finish; plaque-facing zones usually need smoother finish than bone-facing 
• Wet blast: Selective finishing / cleaning with masking / controls to manage zones.

Two-piece 
• Typical substrate: CNC-machined titanium implant body + CNC-machined titanium / Ti-alloy abutment blank 
• Finishing issue: Protect precision connection surfaces; retained residues / contamination and tolerance change risks 
• Wet blast: Mask precision interfaces; clean / condition implant...
