[The implant denture in the laboratory]

Area of Science:

• Dental Implantology
• Prosthodontics
• Biomaterials

Background:

• Current implant prosthodontics utilize diverse devices and kits.
• Two primary systems exist: the gold ring cylinder and the prosthetic abutment core.

Purpose of the Study:

• To analyze and categorize existing implant prosthodontic devices.
• To compare the gold ring cylinder and prosthetic abutment core concepts.
• To outline solutions for parallelism issues in implant restorations.

Main Methods:

• Comparative analysis of available implant prosthodontic systems.
• Classification into gold ring cylinder and prosthetic abutment core categories.
• Review of techniques for addressing parallelism discrepancies.

Main Results:

• The gold ring cylinder system simplifies parallelism but limits fixation to screws.
• The prosthetic abutment core system, similar to conventional abutments, allows for screw, cement, or clip fixation.
• Methods for correcting parallelism include grinding, telescopes, bendable cores, and pre-angulated cores.

Conclusions:

• Implant prosthodontics requires specialized knowledge and adapted workflows for dentists and lab technicians.
• Both systems present distinct advantages and challenges in achieving successful implant restorations.
• Careful consideration of parallelism during surgery and prosthesis design is crucial.
