To Compare the Two Implant Placement Protocols to Evaluate Placement Accuracy and Post-operative Healing of the Implant

March 30, 2026 updated by: Maria L. Geisinger, DDS, MS, University of Alabama at Birmingham

Assessment of Two Implant Placement Protocols to Evaluate Placement Accuracy and Post-Operative Healing

The goal of this study is to evaluate two commonly utilized surgical guide protocols to determine dental implant placement accuracy compared to pre-operative computerized planning, post-operative healing and bone levels to 12-months post-placement, and patient assessed post-operative discomfort and healing using a visual acuity scale (VAS).

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Implant placement deviation from computerized planning
Time Frame: 12 months
Implant placement deviation from computerized planning at 12-month post-placement using CBCT overlay measurement techniques.
12 months
Radiographic marginal bone loss
Time Frame: From baseline to 12 months
Radiographic marginal bone loss as measured using digital measurement tools and calibrated parallel two-dimensional radiographic images from baseline dental implant placement to 12-months post-implant placement
From baseline to 12 months
Patient centered outcomes using the Visual Analog Scale (VAS
Time Frame: 4 weeks
Patient centered outcomes including pain, bleeding, swelling, change in daily activities at 7, 14, and 30 days postoperatively, using the Visual Analog Scale (VAS) This measurement ranges from 0-10 (0 being better and 10 being worse).
