Reconstruction of maxillofacial bone defects with Coralina® HAP-200 hydroxyapatite blocks

Abstract

The results obtained with the application of blocks of Porous Coralline
Hydroxyapatite HAP-200 for the restoration of bone defects in the maxillofacial region
are presented. Each blocks was carved meetly with a hand piece in the surgical act in
order to adapt it to the bone space and finally they were placed and fixed to the
surrounded tissue without osteosíntesis and following the indications and established
norms for the use of this type of implants. The postoperative evaluation was carried
out at the 7 d, month, at three months, at six months and up to year after surgery
keeping in mind the presence and intensity of the pain, erythema, edema, infection
or exposition of the implant biomaterial according to the indication in the protocol of
clinical evaluation of these products as well as the radiographic images. The
study includes 12 patients and the clinical and longitudinal radiographic
evaluation in the first year after implantation demonstrate excellent results as
for the tolerance and biocompatibility of the product, achieving an excellent
aesthetic restoration. In no case adverse reactions to the implanted biomaterial
were found. The obtained results using the coralline hydroxyapatite HAP-200
in block as bone graft substitute in the reconstruction of maxilofacial bone
defects are excellent. It presents a great biocompatibility with the bone tissue
and for this reasons its use is recommended for this type of reconstructive
surgery. The biomaterial is osteointegrated to the bone but it is not reabsorbed.
It is necessary to carry out the correct selection of the patient, as well as the correct
indication of the treatment according to the suggestions and recommendations
