What this trial studies

This clinical trial evaluates the accuracy of two different methods for placing dental implants in patients who are completely edentulous. It is a multicenter, randomized controlled trial that compares dynamic navigation and static template techniques by measuring deviations in implant placement. The study aims to analyze the data using a mixed linear effects model to determine which method provides better precision. Enrollment is competitive among various centers, ensuring a diverse patient population.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older who are completely edentulous or terminally edentulous and have sufficient bone volume for implant placement.

Not a fit: Patients who are not edentulous or do not meet the bone volume requirements may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the accuracy of dental implant placements, leading to better outcomes for patients without teeth.

How similar studies have performed: Previous studies have shown promising results with similar approaches in implant placement accuracy, indicating potential for success in this trial.

Eligibility criteria

Inclusion Criteria:

* 18 years old and above
* American society of anesthesiologists (ASA) Levels 1 and 2
* Satisfy any of the following requirements:

  1. Edentulous maxillary patients
  2. Edentulous mandibular patients
  3. Terminally edentulous maxillary patients (number of remaining natural teeth in the upper jaw 1-4)
  4. Terminally edentulous mandibular patients (number of remaining natural teeth in the lower jaw 1-4)
  5. Full-mouth edentulous patients
  6. Full-mouth terminally edentulous patients (number of remaining natural teeth in one jaw 1-4)
* Implant-supported fixed restorations or implant-supported overdenture restorations
* Sufficient usable bone volume at implant sites, non-implant sites (≥1.5mm of remaining bone width on the labial/buccal and palatal/lingual sides after virtual implant placement in software)
* Maxillary and mandibular options for full-mouth patients are based on the inclusion of more single jaws in the non-bone grafted sites (see virtual peri-implant bone volume requirements in the pre-operative preparation phase)
* Mouth opening of 3 fingers or more
* Single-jawed missing patients treated with systemic periodontal therapy

Exclusion Criteria:

* Have a systemic disease that may affect prognosis (e.g. diabetic patients with glycated haemoglobin \>6.5%, patients on bisphosphonate medication, patients with auto-systemic immune diseases, etc.)
* ASA grades 3 and 4
* Acute inflammation in the oral cavity: including uncontrolled periodontitis (periodontal probing depth \> 4 mm) and untreated acute and chronic apical periodontitis
* Pregnancy or breastfeeding
* History of radiotherapy to the head and neck
* Heavy smokers (more than 10 cigarettes per day)
* Restricted mouth opening (less than three fingers).
* Participation in a clinical trial with another drug or device within 30 days prior to the start of the procedure (study day 0).
