Prosthetic-driven immediate implant placement for optimal aesthetic restoration has been increasing in demand during the last decades but requires higher accuracy. Dynamic navigation has been reported better implant positioning in immediate implant placement compared to free hand procedure. On the basis of dynamic navigation, robotic system uses the robotic arm to replace the manual process of implant bed preparation and implant placement, therefore improving the accuracy of implant placement theoretically. The goal of this randomized controlled trial is to compare the positional implant accuracy, the surgical time, and patient satisfaction between dynamic navigation and robotic assisted immediate implant placement in maxillae. Subjects will be randomized to either group based on the allocation. The accuracy of placement will be assessed evaluating the difference between the planned and the actual position using a follow-up CBCT scan taken at the end of the surgery. Subjects will be followed up for one year to assess both patient reported and professional outcomes.
Prosthetic-driven immediate implant placement for optimal aesthetic restoration has been increasing in demand during the last decades but requires higher accuracy. Dynamic navigation has been reported better implant positioning in immediate implant placement compared to free hand procedure. However, dynamic navigation faces the following deficiencies in immediate implant placement. Firstly, it has a steep learning curve. Secondly, the rigid palatal bone wall of the socket will force the direction of drill deviating buccally. On the basis of dynamic navigation, robotic system uses the robotic arm to replace the manual process of implant bed preparation and implant placement, therefore improving the accuracy of implant placement theoretically. The goal of this randomized controlled trial is to compare the positional implant accuracy, the surgical time, and patient satisfaction between dynamic navigation and robotic assisted immediate implant placement in maxillae. Subjects will be randomized to either treatment modalities based on the plan. The accuracy of placement will be assessed evaluating the difference between the planned and the actual position using a follow-up scan taken at the end of the surgery. Subjects will be followed up for one year to assess the professional outcomes.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Implant positional accuracy
Implant accuracy will be measured as discrepancy between the digital plan and the actual position of the implant. (Global deviation at platform and apex, Angular deviation)
Time frame: immediately after surgery
Surgery time
Time needed for surgery procedure will be recorded from anaesthesia to connection of cover screw/healing abutment.
Time frame: intraoperative
Pain perception
Patient pain perception during surgery will be recorded using visual analogue scale (VAS with range from 0 to 10 with 10 being the highest possible pain experience).
Time frame: Immediately after surgery
Pain perception
Patient pain perception after surgery will be recorded using visual analogue scale (VAS with range from 0 to 10 with 10 being the highest possible pain experience).
Time frame: 7 days after surgery
Surgeon preference
Assessed using a visual analogue scale (VAS, 100 mm, with 0=least desirable option and 100 = most desirable option.
Time frame: Immediately after surgery
Soft tissue changes
Assessed by midfacial recession, mesial and distal papillary recession.
Time frame: immediately after crown delivery
