Conometric Connection for Implant-Supported Crowns: A Prospective Clinical Cohort Study

Area of Science:

• Dental Implantology
• Prosthodontics
• Biomaterials

Background:

• Traditional screw and cemented dental implant connections have limitations.
• Conometric connections offer an alternative for implant-supported prostheses.

Purpose of the Study:

• To evaluate the one-year clinical outcomes of conometric connections in dental implants.
• To assess biological responses and prosthodontic complications.

Main Methods:

• A cohort of 22 patients received 70 implants supporting 33 rehabilitations.
• Clinical evaluations were performed at baseline, 6 months, and 12 months.

Main Results:

• All implants achieved successful osseointegration without losses or peri-implant inflammation.
• Marginal bone loss was minimal (-0.51 ± 0.93 mm over 12 months).
• Nine cases experienced coupling stability loss, but no abutment screw loosening or crown chipping occurred.

Conclusions:

• Conometric connections demonstrate successful osseointegration and minimal complications after one year.
• This connection type shows potential for simplified handling and improved marginal adaptation in dental restorations.
• Further long-term studies with larger cohorts are recommended.
