Regenerative surgery

Some patients suffer from a severe bone deficiency, a situation that leads them to not having enough jawbone (in quality or quantity) and this is a problem for example if they have to undergo implant surgery (but not only): If the bone is poor the implant cannot be loaded.

Before resorting to solutions such as zygomatic implants, the possibility of Perform bone reconstruction (or regeneration) surgery applying a series of techniques whose purpose is to Regenerate the bone of the jaw or jawbone.

Bone grafts

La bone grafting technique is used when it is necessary Increase the thickness or height of the bone maxillary or mandibular in case the patient needs to undergo implant surgery.

The operation involves a small bone transplant which can be autologous (the bone is taken from the patient himself) or heterologous (The bone that is transplanted is synthetic, whether of animal origin or not).

Once bone grafting has been performed, it is necessary to wait a few months (usually less than six) so that The patient's bone reaches the appropriate height or thickness To make it possible to load the system.

Resorbable membranes

Membranes are used in all situations where a support to hold the graft in place until the graft is fully integrated into the bone (Without support, the graft may be mobile).

These membranes, synthetic or biological molecules, they are called resorbable precisely because Are completely absorbed by the bone And then, once inserted, it is not necessary to remove them at a later date.

Titanium grids

Grids (also called mesh) titanium membranes have the same function as resorbable membranes, viz. Support a graft until it is fully osseointegrated.

Titanium grids are chosen to be used. When more support is needed that resorbable membranes cannot give, so it is a technique that is usually used in the More complex regenerative interventions.

Another difference with membranes is that grids are not resorbable: once the graft has integrated with the bone, and thus they have finished performing their function, the patient must undergo a brief intervention to be able to remove them.

Are regenerative surgery techniques used only when there is little bone for an implant?

Although the goal of all bone regeneration techniques is to increase bone height/thickness, loading a dental implant is not always the reason; there may be other Diseases or situations that cause bone loss:

• mouth trauma
• advanced age or having been without teeth for a long time
• osteoporosis
• untreated periodontitis
• pathologies affecting the oral cavity
• cigarette smoke

To assess the severity of any bone loss and decide which regenerative surgery technique to use, it is necessary to perform a 3D CT scan that accurately returns details and information Regarding the thickness of the bone and its quality.
