Accuracy of pre-made screw-retained temporary crowns placed with digital planning and guided implant surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Eligible adults will receive CBCT and intraoral scans to create a virtual implant and restoration plan and to fabricate a prefabricated screw-retained provisional crown. A fully guided implant placement with rotational control will be performed and the prefabricated provisional will be placed immediately after implant insertion. The planned digital positions will be compared with postoperative clinical outcomes using linear, angular, and rotational deviation measures to determine trueness and precision. The primary practical outcome is whether the provisional restoration seats passively without significant adjustment.

2. Partially edentulous patients requiring replacement of a single tooth with an immediately loaded dental implant.
3. Patients classified as ASA I or ASA II according to the American Society of Anesthesiologists physical status classification.
4. Patients with clinical conditions allowing immediate implant placement with a minimum primary stability of ≥25 Ncm.
5. Ability to understand the study procedures and provide written informed consent.
6. Willingness to comply with the study protocol and attend required clinical visits.

Exclusion Criteria:

1. Patients classified as ASA III or ASA IV, or with uncontrolled systemic conditions that may interfere with study participation.
2. Presence of psychiatric or cognitive disorders that may compromise informed consent or protocol compliance.
3. Inability to comply with the visit schedule or required evaluations.
