Bone reconstruction using 3D manufactured bone blocks
It is often the case that patients undergoing implant treatment require bone reconstruction procedures at the site of the lost tooth or teeth. This is necessary to create a suitable base for the implant. The more time that passes since tooth extraction, the more atrophy, i.e. natural bone atrophy caused by the lack of mechanical load, progresses.
The use of CAD/CAM technology in modern implantology allows the development of precisely dimensioned allogenic bone blocks (i.e. derived from human tissue).
What does bone reconstruction with 3D-made bone blocks look like?
In addition to reconstructions using artificial bone substitute materials, dentists-implantologists also carry out autogenous grafts, i.e. grafts using the patient’s own bone (from the chin, the sinus cavity and, in the case of extensive defects, also from the hip plate).
Obviously, autogenous transplantation, although it yields better quality bone graft material, is associated with trauma to the site where the tissue is taken. With the development of implantology, allogenic materials, i.e. from a human tissue bank, are therefore increasingly used. Allograft (bone from a tissue bank) does not trigger an autoimmune reaction. It is an ideal material for stimulating new bone growth.
For a successful reconstruction, the bone block must adhere perfectly to the alveolar process. The three-dimensional radiological image in combination with design using CAM software allows the bone block to be individually shaped exactly according to the patient’s needs. Such an individual graft block is milled according to the design from the allograft and then cleaned and sterilised to be ready for transplantation.
Bone reconstruction – dentist Szczecin
The implant dentist performs the augmentation procedure under local anaesthesia. After exposing the bone base, the block is fixed with special screws for osteosynthesis (fusion, fusion). Around the healing screws, the wound is closed with sutures. After the procedure, the dentist orders a follow-up radiograph. For at least four weeks, the patient must avoid mechanical stress on the operated area, both during chewing of food and hygiene procedures. The patient uses a chlorexidine rinse to protect the oral cavity from decay. The dentist also prescribes an antibiotic and painkillers. The sutures are removed 10 days after surgery. Every four weeks, the operated area should be checked at the dentist’s office. Full fusion of the block with the patient’s bone occurs after approximately six months. After this time, tooth implants can be inserted.
Bone reconstruction using 3D-engineered bone blocks allows for a stable base for implants, even in cases of advanced atrophy of the patient’s own bone. Other advantages of this solution include:
Effective support for natural bone regeneration in the patient’s body
A low degree of resorption during the healing process, which minimises the risk of having to carry out additional augmentation procedures
No collection of the patient’s own material and therefore no additional trauma
Thanks to the individual shaping of the bone block, surgical time is reduced, which helps soft tissue healing
The augmentation procedure using 3d shaped blocks is available at the Koryzna Clinic dental office in Szczecin. Our dentists will provide more information during the consultation.
