What is it?
There are cases in which implantology operations are not possible due to a lack of sufficient bone: bone regeneration is the surgical branch of specialisation that involves the use of different new bone tissue construction techniques, to enable the fitting of stable dental implants, thus creating good functional/aesthetic conditions.
In what cases is it applied?
Whenever there is a need to increase bone volume, very often due to the prolonged absence of teeth.
What techniques exist?
There are numerous ones, but here are just some:
1. Mini maxillary sinus lift:
Applied to the upper jaw, when only minimal amounts of bone are lacking upon implant positioning, in the maxillary sinus, a concave area near the cheek bones.
During the regenerative procedure the implant is placed in the desired position and may require the use of new bone and biomembrane.
It is performed under local anaesthetic and the patient feels no pain.
Osseointegration takes around 4 months following the operation (the regrowth of bone around the “titanium screw” and as soon as it has completely stabilised, prosthetisation, or tooth application, can take place.
2. Large sinus lift
Large sinus lift is a more complex technique compared to the previously described one and is performed when the quantity of bone tissue requiring bone regeneration is greater.
The operation is followed by a few months of waiting for the bone to correctly regenerate, to enable the application of future dental prostheses.
In some cases implants are stabilised as part of this bone regeneration technique.
3. Computed guided GBR (Guide Bone Regeneration)
This surgical technique is often carried out on the lower arch to regenerate missing bone structures.
This technique involves the use of membranes and filling materials to fill all areas where defects are present with “missing bone”.
In some cases, custom made titanium meshes are used: the membrane is replaced by a previously designed titanium plate, based on a virtual computerised reconstruction, and then “printed” and applied. This procedure offers the advantage applying a previously designed device that is perfectly customised to the specific patient.
Custom-made grilles can made based on digital design using the CAT of the patient to ensure utmost precision with reference to individual bone defects.
This considerably reduces the invasiveness of the procedure, with a significant reduction of intraoperative and recovery times.
This is a day surgery procedure performed under local anaesthetic and patients also have the option of conscious sedation, making it a very straight forward operation to face.
The surgery Dental@Med works with Dr. Valerio Ramieri, a Medical Surgeon with a PhD in Maxillofacial Surgery, and an expert in Bone Regeneration.
