• Maxillary Dentures Supported by Mushroom-Shaped Mucosal Implants?

  Dr. Flynn asks:
  A local general dentist is advertising palateless maxillary dentures supported by mushroom-shaped mucosal dental implants.

• Implants Showing Thru Gingival Tissue

  Dr. Mena asks:
  I recently did a few immediate loading cases with root-formed
  dental implants and composite resin temporization on titanium or zirconia
  abutments.

  the extraction, which was the reason for the extractions. All cases
  were treated with antibiotics after the extractions and dental  implant
  placement. The dental implant fixtures […]
