Dental Implant Clinical Trial
Official title:
Closure of Implant Emergence Profile
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
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.
The main objective is to study the effect of removal of a healing abutment on the closure of
the EIP volume at 5 minutes.
This non-interventional study is a prospectively recruited research of the participants and a
cross-sectional measure of the judgment criteria (during a single visit). The study is
mono-centric, it will take place in the odontology department of Toulouse Hospital.
The question is to know if the decrease in the volume of the PEI is significant during the
preparatory phase of the implant impression where the PEI is no longer supported by the
healing screw over a period of 5 minutes.
Optical impressions are designed to record adjacent implant site teeth and peri-implant soft
tissue PEI using a 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.
