1. What is a dental implant?
A dental implant is an artificial "root" that we surgically place in the jaw bone under the gum. It can replace one or more missing teeth. On this artificial root, we are going to fix a dental prosthesis, in general a ceramic crown.
The implant is made of titanium, a metal chosen for its high biocompatibility.
2. Why install an implant?
Getting a dental implant is not only an aesthetic act; this improves the patient's quality of life in particular by restoring functional comfort by overcoming the difficulties of chewing and speech. It also avoids the inconvenience associated with removable prostheses or bone loss linked to the extraction of a tooth and its consequences.
3. What are the contraindications?
To place an implant, we need on the one hand that the gums are healthy and on the other hand, that the bone is of good quality and in sufficient quantity to accommodate the entire length of the screw to allow its fixation.
Certain medical contraindications make implant placement impossible:
diseases that may have weakened the immune system
severe renal failure
The most common causes of implant failure are:
smoking limiting vascularity of the gums
poor design or implementation of the different stages of treatment
4. Is there an ideal age for implant placement?
As indicated in the question "contraindications", implant placement depends on the state of the bone and its environment.
If these conditions are met, there is a priori no question of age. We therefore do not place an implant on people under 18 because the bone tissue must be fully developed during the procedure.
5. What if I don't have enough bone tissue?
During our diagnostic appointment, we will assess the lack or not of bone or gum tissue.
If this is the case, there are certain techniques to remedy the lack of bone with the use of shorter and wider implants, or perform a bone graft such as sinus filling for example.
6. How is an implant placed?
Each surgery is unique, depending on the case, the type of implant and the tooth or teeth to be replaced. Thus, the number of sessions can generally vary between one to three meetings.
We perform our procedures in a dedicated operating room to ensure asepsis during the installation.
Before the intervention, we perform a 3D scanner (or Cone-Beam) of the patient's jaw. These 3D images are transmitted and used by specialized simulation software to visualize the available bone volume as well as any anatomical obstacles (sinus, nerves, etc.).
The dental surgeon can then directly on his screen simulate the positioning of the future implant (s), its shape and size, its placement angle and thus optimally anticipate the surgical intervention.
The operation is always performed under local anesthesia.
It generally takes place in 2 parts.
The first consists in placing the implant:
access to the bone by incising and peeling off the gum
preparation of the bone to receive the screw using suitable diameter drills
placement of the screw and closure of the gum with stitches
We then have a phase of osteointegration, that is to say a phase during which the direct structural and functional connection between living bone and the surface of an artificial implant takes place. This phase can last from several weeks to several months, the patient can sometimes benefit from so-called transition prostheses. The second part consists in the installation of the ceramic prosthesis:
re-opening of the gum
screwing the ceramic prosthesis

7. How long do dental implants last?
The lifespan of implants is linked to the health of the surrounding gum and bone.
8. How to maintain dental implants?
Even though dental implants inherently require little maintenance, it is important to have excellent oral hygiene in order to avoid gum infections in particular.
An annual visit is also necessary to check that there is no deterioration of your dental implant.
