Not Applicable

Terminated

• Conditions: Dental Implants
• Interventions: Procedure: Implant surgery assisted by passive robotics; Procedure: Conventional implant surgery

• Registration Number: NCT05218941
• Lead Sponsor: University Hospital, Toulouse

Brief Summary

The use of a passive robotic system allows the practitioner to widen the field of indications of flapless surgical access to the implant with an increased operative security and the possibility of an operative modification of the surgical protocol.

Detailed Description

In recent decades, the placement of dental implants has become a common procedure for the rehabilitation of partially or completely edentulous patients. The placement of implants requires good visibility of the bone support to avoid accidents such as bone fenestration. This is why, except in very favourable cases where the bone crest is wide, unconcavated and with an ideal periodontal support, it was until then necessary to proceed with a flap before placing the implant. This invasive surgical protocol necessary for implant placement with good visual access has negative parameters such as :

* detachment of the periosteum and therefore risk of bone resorption

* longer intervention time

* need for sutures

* post-operative pain. On the other hand, flapless techniques, which respect the periosteum and periodontium, offer simpler surgical outcomes, reduced risk of bleeding and infection, less bone resorption, and overall better healing. However, the absence of an access flap to the implant site requires special anatomical conditions to avoid any risk of bone fenestration during drilling, and this technique is directly related to the operator's experience. Increasing the number of cases treated by flap-free implant surgery with increased safety is now possible thanks to computer-assisted surgery and passive robotics.

The main objective is to compare the patient's post-operative pain outcomes between passive robotic implant surgery and conventional implant surgery.
