Background:

The optimal retentive mechanism for adjacent implant-supported crowns remains debated.
Current literature lacks a standardized classification for restoring adjacent implants.

Purpose of the Study:

To propose a comprehensive classification system for prosthetic designs when restoring adjacent implant-supported crowns.
To delineate available retentive and splinting options for adjacent implant restorations.

Main Methods:

A review of current literature on adjacent implant restorations.
Development of a classification system categorizing prosthetic designs from Class I to Class VI.

Main Results:

Six prosthetic design options are proposed: Class I (individual cement-retained), Class II (individual screw-retained), Class III (individual screw-retrievable/cement-retained), Class IV (splinted cement-retained), Class V (splinted screw-retained), and Class VI (splinted screw-retrievable/cement-retained).

Conclusions:

The proposed classification system provides a framework for understanding and selecting appropriate prosthetic designs for adjacent implant-supported crowns.
This system aims to standardize terminology and guide clinical decision-making in complex implant restorations.
