Summary

This clinical trial aims to evaluate the in vivo accuracy of a fully digital workflow for the immediate placement of a previously fabricated screw-retained provisional crown using digital planning and guided implant surgery. The study will be conducted in partially edentulous adult patients requiring the replacement of a single tooth with an immediately loaded dental implant.

The main objective of the study is to assess the accuracy (trueness and precision) of the planned digital implant position and provisional restoration by comparing the virtually planned position with the actual clinical outcome after guided surgery. Emphasis will be placed on linear, angular, and rotational deviations at both the implant and provisional restoration levels.

Participants will undergo a fully guided implant placement procedure with rotational control, followed by the immediate placement of a prefabricated screw-retained provisional crown designed during the digital planning phase. Postoperative intraoral scans will be obtained to register the final implant and restoration positions.

The planned and achieved positions will be compared using three-dimensional analysis software to quantify deviations and determine whether the accuracy achieved remains within clinically acceptable limits.
