Summary

In the case of unitary edentulousness, a dental implant is a prosthetic device fixed in the bone which makes it possible to receive a fixed dental prosthesis (crown). Peri-implant soft tissues (gums) play an essential role in the integration of the crown. Indeed, the implant gingival emergence profile provides an aesthetic integration mimicking that of a natural tooth. This implant emergence profile (EIP) is modeled during the surgical and / or prosthetic phases.

The problem comes from the labile character of the EIP (Emergence Implant Profile). If the literature evokes this problem, the instability of the volume of the EIP during the impression phases has never been measured. Moreover, the three-dimensional behavior of the EIP over time (kinetic) during the acquisition phases is not known.

Objective study of the mobility of gingival tissues of the implant emergence profile (IEP), using an intra-oral optical camera, would scientifically measure the labile aspect of the IEP and improve the procedure of registration of peri-implant soft tissues

Conditions

  • Dental Implant

Interventions

OTHER

Four intra-oral optical impression taken successively

Four intra-oral optical impression images will be taken successively on a patient: Optical impressions are designed to record adjacent implant site teeth and peri-implant soft tissue PEI using an Optical Camera. The optical camera works like a camera and does not come into contact with the patient's mucous membranes or teeth. The images obtained are saved in STL format on an anonymized file. The 4 aligned surfaces thus obtained will be cut using a 3D image processing software. A fixed cylinder will extract the PEI from the 4 surfaces. The volume of these 4 PEIs at T0 min, T30 sec, T2 min and T5 min will be calculated using a software
