Bone Regeneration

23 Jun 2011 | Treatments

Bone regeneration is recommended when bone tissue is lost in the site where the operator wants to place an implant. First of all, it is necessary to study your case carefully: the occlusion of your mouth should be reproduced using chalk models to determine what would be the optimal position with the opposing antagonist teeth fitting together. Moreover, X-ray and tomography should be performed to obtain the correct information concerning the amount of bone that is lost vertically and/or horizontally. Only then the prosthetically-guided implant can be placed where it fits perfectly in with the other teeth.

Bone loss could be such as to require ad hoc surgery for bone regeneration. We will use very small screws that, covered by a membrane, will make a sort of tent or scaffold in the bone loss site underneath the gum. Such scaffold is filled with artificial bone and bone from the patient’s body, which we harvest in an absolutely non-traumatic way with Piezosurgery, an ultrasound instrument that gently collects autogenous bone chips. Regenerative implant surgery, or the maturation of the new bone underneath the membrane requires 4 to 6 months before the implant can be placed.

We prefer to use Piezosurgery also for implant placement, in order to preserve and minimize damage to the regenerated bone.
In case of lack of vertical bone in the upper dental arch, sometimes we will have to elevate the maxillary sinus. Again we’ll be using artificial bone, autogenous bone and membrane. Maturation time is always between 4 and 6 months. A biological rest period is always needed for complete remineralization of the new bone.
When we have more limited bone loss, we can perform regeneration at implant placement. In such a case, the bone defect and the implant will be covered by the bone substitute and, finally, by the membrane. Eventually a small crestal lifting of the sinus will be accomplished through a simplified technique.

We at Studio Moll count on your cooperation. You should closely follow post-operative instructions, refrain from smoking during the healing process and always maintain an appropriate dental and oral hygiene. If we deem it useful, we will also propose some nutritional supplement. We believe that bone metabolism can be helped by the vitamins and minerals that are involved in the bone remodelling processes.

Some patients cannot, for health reasons, undergo two operations in a short time if, for instance, if they are on anticoagulant treatment, which cannot be interrupted or drastically reduced to perform surgery. Under certain medical conditions there are limitations to surgery and minimally invasive techniques are recommended. A patient may prefer non-surgical procedures that in some cases are offered by orthodontists.
Orthodontics may be used to move the teeth, either vertically or horizontally, thus obtaining a true bone regeneration, which allows for successful placement of prosthetically-guided implants.
