Beskrivelse
Inclusion Criteria:
- Age ≥ 18 years
- Monlateral distal free-end edentulism
- Presence of natural teeth or reliable fixed restorations mesial to the edentulous area to provide support and stability for the surgical guide
- Preoperative CBCT assessment shows available bone height ≥8 mm and bone width ≥5 mm in the edentulous area, allowing implant placement without concomitant complex bone augmentation
Exclusion Criteria:
- Uncontrolled periodontitis or acute oral infection
- Uncontrolled systemic diseases (e.g., diabetes, severe osteoporosis) or pregnancy/lactation
- History of head and neck radiotherapy or current use of intravenous bisphosphonates
- Severe limited mouth opening (interincisal distance <35 mm) affecting surgical instrument manipulation

Eksperimentel: Robot assisted dental implant placement surgery
Novel robotic implant placement
|
The test intervention will comprise autonomous dental implant placement using the YakeRobot.
The 3Shape treatment planning will be exported into the YakeRobot software for robotic planning and the robotic planning will be finalized.
Two Straumann implants will be positioned to retain a bridge, following the standard YakeRobot implant placement procedure.

|
Aktiv komparator: 3D printed static guide assisted dental implant placement surgery
standard of care
|
The control intervention will consist of guided implant surgery with a static guide, planned using the 3Shape software and custom 3D-printed following the international standard of best practice.
Two Straumann implants will be positioned to retain a bridge, following the Straumann guided surgery placement protocol.

Tidsramme |
|---|---|---|
|
Degrees of Implant misangulation
Tidsramme: 3 months after implant surgery
|
The implant position was acquired 3 months after implant surgery with an intraoral scan (TRIOS 3; 3Shape) with a scan body in place.
The actual position was compared with the digital plan by the accuracy analysis software (DentalNavi 2.2; YakeRobot Technology Ltd) by an independent calibrated examiner blind to group allocation.
The discrepancy between planned and actual implant axis angulation will be measured in degrees.

Food Frequency Questionnaire (FFQ)
Tidsramme: Preoperative; 3 months after prothesis delivery; 12 months after prothesis delivery.
|
Dietary intake assessed using a validated Food Frequency Questionnaire that calculates the long term dietary intake in grams of the different food types
|
Preoperative; 3 months after prothesis delivery; 12 months after prothesis delivery.
|
|
Oral Health-Related Quality of Life (OHIP-14)
Tidsramme: Preoperative; 3 months after prothesis delivery; 12 months after prothesis delivery.
|
Oral health-related quality of life measured by the OHIP-14 questionnaire (14 items), using a 5-point Likert scale with Higher scores indicate poorer quality of life.
|
Preoperative; 3 months after prothesis delivery; 12 months after prothesis delivery.

Oral Rinse Sample Microbiome
Tidsramme: Preoperative; 3 months after prothesis delivery; 12 months after prothesis delivery.
|
Collection of oral rinse fluid for analysis of microbiome
|
Preoperative; 3 months after prothesis delivery; 12 months after prothesis delivery.
|
|
Stool Metagenome
Tidsramme: Preoperative; 3 months after prothesis delivery; 12 months after prothesis delivery.
|
Fecal sample collection for gut microbiome analysis using a metagenomic approach.
|
Preoperative; 3 months after prothesis delivery; 12 months after prothesis delivery.
|
|
Blood Sample
Tidsramme: Preoperative; 3 months after prothesis delivery; 12 months after prothesis delivery.
|
Venous blood will be collected and processed to obtain plasma.
Plasma samples will be analyzed using metabolomics profiling to assess metabolic changes associated with the intervention.
|
Preoperative; 3 months after prothesis delivery; 12 months after prothesis delivery.
|
|
Masticatory Function
Tidsramme: Preoperative; 3 months after prothesis delivery; 12 months after prothesis delivery.
|
Masticatory performance is assessed using a two-color chewing gum test.
Participants chew a dual-color gum (e.g., blue and red) for a standardized number of cycles.
The degree of color mixing is evaluated by image analysis, providing an objective measure of chewing efficiency.
|
Preoperative; 3 months after prothesis delivery; 12 months after prothesis delivery.
|
|
Postoperative Diary (First 2 Weeks)
Tidsramme: From immediately after surgery to 14 days postoperatively (diary returned at 2-week follow-up).
|
Patient-recorded daily symptoms including pain (0-10 scale), swelling, analgesic use, bleeding, and any unusual events during the first 14 days after surgery.
Diary is collected at the 2-week suture removal visit.
|
From immediately after surgery to 14 days postoperatively (diary returned at 2-week follow-up).
|
|
Clinician-Reported Outcomes
Tidsramme: Immediately after surgery.
|
Surgeon-reported outcomes assessed immediately after surgery, including: surgical difficulty (e.g., VAS), intraoperative complications, calibration issues, need for conversion to freehand, and overall procedural success.
|
Immediately after surgery.
|
|
Treatment Planning and Surgical Procedure Times
Tidsramme: Planning time: recorded preoperatively; Surgical time: recorded intraoperatively.
|
