Bone regeneration, a technique to place dental implants

Bone regeneration of the jaws is a technique that consists of reconstructing the bone in those areas where there are deficiencies in order to be able to place dental implants.

Dentistry uses it in those cases in which the bone volume is not sufficient to place dental implants in the ideal position or to achieve sufficient dental esthetics. They occur after severe maxillary bone atrophy, traffic accidents, trauma, periodontal disease, etc.

Bone regeneration process

In the process of bone reconstruction, bone tissues from the same individual are used because they are the ones with which the best results are obtained. However, alloplastic materials, xenografts, etc. can also be used.

In order to carry out this type of treatment, some previous studies are carried out, such as:

  • Interview with the patient to know exactly what he/she wants.
  • Study models of the patient and preparation of a three-dimensional radiographic template, with the ideal position of the implants.
  • Radiographic study to assess the position of the teeth in relation to the bone. It consists of an orthopantomography and a cone beam computed tomography that is done with the three-dimensional radiographic template.
  • Analysis of the patient to know his general condition.

The process lasts approximately four to six months. If implant placement is performed simultaneously with rehabilitation, it can be completed in about six months. However, if the implant placement is deferred, the process will take up to eight months.

Complications of the bone regeneration process

Complications exist as in any surgical treatment, but they can be greatly reduced with a good clinical history. In general, there may be cases of inflammation, possible hematomas and, on rare occasions, exposure of the bone graft.

In cases where the patient is a smoker, there are a greater number of complications such as bone graft failure, poorer healing and vascularization of the graft. The patient should not use a removable dental prosthesis in the grafted area that could damage it.
