Single _ Drill Vs Full Sequence Guided Implant Placement

This randomized clinical trial aims to compare the accuracy of single-drill (pilot-guided) computer-guided implant surgery versus full-sequence computer-guided dental implant placement. The study evaluates clinical and radiographic outcomes, focusing on apical, angular, coronal, and depth linear deviations using post-operative cone-beam computed tomography (CBCT) superimposition.

Treatment and study plan

Full-sequence computer-guided dental implant placement.

Procedure

Dental implant placement using full sequence computer guidance with all sequential drills and metal reducers

Single-drill computer-guided dental implant placement

Procedure

Dental implant placement using first-drill (pilot-guided) computer guidance, followed by freehand sequential drilling and placement

Primary outcomes

  1. Apical deviation

    Time frame: Immediately after surgery (Post-operative CBCT).

    The linear deviation between the planned and actual implant apex position measured on post-operative CBCT superimposition.
