Bone Graft & Regeneration, Sinus Lift

1. Why operate?
In order to hold the implant in place and ensure its maintenance over time, it is essential that your jawbone is not too thin or too soft. If it is the case, we may have to achieve an increase in bone volume by grafting.

2. Two types of grafts
There are different methods of bone augmentation:

  • Synthetic grafting with the addition of a biocompatible material containing calcium (hydroxyapatite) and growth factors. Gradually, natural bone replaces the material. It is important to note that despite the use of external bodies, this technique does not carry any risk of disease transmission.

  • Autogenic transplant with removal of bone from the patient (iliac or mandibular bone removal). This type of graft, although less frequent than synthetic grafting, allows the reconstruction of large bone deficits by ensuring rapid healing and very good resistance to infection. Biosynthetic particles are often added to fill the volumes perfectly.

The grafted bone is placed either in the form of small blocks or in the form of shred material.


3. What type of intervention?
Two types of bone grafts can be performed: fillers or apposition grafts.

  • Filling grafts are performed

    • at the level of the maxillary sinuses (sinus lift) to restore sufficient bone height allowing subsequent placement of the implant.

    • during dental extraction for replacement by an implant. The alveolus is then filled right away to avoid bone loss during healing.

  • Apposition grafts are performed on the maxilla or on the mandible when the width of the bone crest is not sufficient to accommodate the future implant because of its diameter or inclination. The sample usually requires general anesthesia.

4. Usual operating suites and post-operative care

The patient will present

  • generally moderate pain

  • limitation of mouth opening for a few days

  • facial edema, the extent and duration of which vary greatly from one individual to another;

Anti-inflammatory and pain-relieving treatment with analgesics allows to reduce swelling and pain.


To allow good healing, it is important to follow these tips:

  • have excellent oral hygiene

    • mouthwashes the next day and until complete healing (5 to 8 days)

    • brushing teeth and gums with an ultra-soft brush the next day

  • have a mixed and lukewarm or cold diet, like mash or compote, in the first 3 to 5 days. Avoid overly salty or acidic foods

  • quit smoking completely before and after the procedure

  • in the event of a sinus bone graft, large and violent blowing efforts should be avoided during the first weeks;


At the same time, antibiotics prevent infections.

5. Before placing the implant
It is usually necessary to wait 4 to 6 months after the bone graft before being able to place the implant. We will perform a CT scan to check the bone volume finally available.
