Non-Guided vs. Guided Surgery to Immediately Loaded PrimeTaper Implants in Partially Edentulous Patients
- Conditions
- Partially Edentulous Maxilla or Mandible
- Interventions
- Device: PrimeTaper EV
- Registration Number
- NCT05264545
- Lead Sponsor
- McGuire Institute
- Brief Summary
A 510k approved dental device for subjects requiring single or multiple tooth replacement with implants where immediate restoration/loading is preferred.
- Detailed Description
The rationale for this study is to provide scientific data on the clinical performance and patient reported outcomes of the PrimeTaper EV implant when utilizing non-guided vs guided surgical technique. The PrimeTaper EV implant has the OsseoSpeed surface, which is especially indicated for use in soft bone applications where implants with other surface treatments may be less effective.
The main interests of this study are to assess the survival and the success rates of the implants supporting maxillary or mandibular fixed single or 2-fixture restorations after 1, 2, 3, 4 and 5 years in function

Study & Design
- Study Type
- INTERVENTIONAL
- Study Design
- SINGLE_GROUP
- Arm && Interventions
Group Intervention Description Single Arm PrimeTaper EV There are no arms in the study, it is a non randomized, controlled study
- Primary Outcome Measures
Name Time Method To evaluate implant survival rate at 1 year after final restoration attachment (screw retained when feasible) with single and multiple (fixed bridges) PrimeTaper EV implant(s) utilizing non-guided versus guided surgery 1 year after final restoration Number of remaining implants counted clinically and radiographically, i.e. 'Yes' or 'No' for each implant where 'Yes' means that the implant is still remaining and 'No' means that the implant is not remaining.
- Secondary Outcome Measures
Name Time Method Implant stability by manual clinical examination throughout study, up to the 5 year follow up Mobility (manual stability) will be assessed by a percussion test for resonance indicative of bone to implant contact vertically and laterally.
Implant survival rate 2, 3, 4, and 5 years after final restoration attachment Number of remaining implants counted clinically and radiographically, i.e. 'Yes' or 'No' for each implant where 'Yes' means that the implant is still remaining and 'No' means that the implant is not remaining.
Condition of the peri-implant mucosa (Suppuration by visual inspection). measured at 12 days (no BOP, PPD), 16 weeks, 20 weeks, 6 months, 1,2,3,4,5 years, Suppuration presence or absence will be measured following implant placement by using a scoring system of 0-1. 0 being no suppuration and 1 being suppuration is present. It is being identified by visual inspection and palpitation of moderate inflammation.
Prosthetic survival 5 years after final restoration attachment Proportion of original permanent prosthetic restorations still in place at the 5 years after final restoration attachment.
Maintenance of marginal bone levels on patient- and implant level. throughout study up to the 5 year follow up visit Changes (mm) in marginal bone level (MBL)
Condition of the peri-implant mucosa (Plaque Index) measured at 12 days (no BOP, PPD), 16 weeks, 20 weeks, 6 months, 1,2,3,4,5 years, Plaque index will be measured following implant placement by visual inspection using a scoring system of 0-1, 0 being no plaque is present and 1 being plaque is present.
Condition of the peri-implant mucosa (Recession) measured at 12 days (no BOP, PPD), 16 weeks, 20 weeks, 6 months, 1,2,3,4,5 years, Recession will be measured following implant placement by placing a probe between the tooth and gum to record depth of recession in millimeters from the crown margin to the gingival margin rounded to the nearest 0.5 mm.
Condition of the peri-implant mucosa. measured at 12 days, 20 weeks, 1,2,3,4,5 years Keratinized Tissue Width (KTw) will be measures following implant placement
Investigator Assessment of the Implant-Prosthetic Complex 20 weeks and 5 years. Evaluation of Bone Level of the permanent prosthetic restoration n a 4 point scale (1=very good, 2= good, 3=acceptable, 4=not acceptable)
Prosthetic success 5 years after final restoration attachment. Analysis of successful permanent prosthetic restorations (implant-prosthetic complex); Number of suprastructure fractures, technical repairs 5 years after final restoration attachment.
Patient Reported Outcomes (PROs) 20 weeks, 6 months, years 1,2,3,4,5 subjects will be interviewed to ask about Satisfaction using a 0 (completely dissatisfied) -10 (completely satisfied) point grading system
Implant success throughout study up to the 5 year follow up visit Proportion of implants with the derived answer 'No' on the occurrence of "pain", "mobility", "≥2 mm radiological bone loss from initial placement", "infection", "radiolucency" and "6" or greater on the Subject Satisfaction PRO Question and "Very good", "good" or "acceptable" on each Investigator Evaluation of Esthetic Outcome, Function, Gingival Health, Bone Level
