The process of bone atrophy begins immediately after tooth extraction. When we delay the restoration of missing teeth for a long time, bone and gum atrophy intensifies. Inflammation of periradicular tissues and periodontitis can also intensify the degradation processes. Teeth adjacent to the area of atrophied bone may tilt, causing bite problems and weakening their stability. Bone atrophy is the most serious reason for disqualification for dental implant surgery.

Bone regeneration in the implant area
During the implant consultation, the doctor will perform a CT scan, which allows the height and width of the alveolar process to be measured accurately. This allows the appropriate implant to be selected. If the bone is too low in the vertical dimension, the implantologist can suggest a short implant, but if there is not enough space in the transverse dimension of the alveolar process, you need to proceed with bone regeneration for the implant.
Maxillary and mandibular bone regeneration — Szczecin
Maxillary bone regeneration is possible with biocompatible bone substitute materials and collagen membranes, as well as bone blocks from a certified tissue bank. Bone reconstruction can be performed as a separate procedure, or accompany implant procedures — it all depends on the degree of bone atrophy and anatomical conditions. The regeneration period usually lasts from 4 to 6 months. With the help of mandibular or maxillary regeneration techniques, we can significantly improve the conditions for implantation.
What is guided bone regeneration?
Guided bone regeneration involves creating favorable conditions for the body to restore alveolar bone tissue. To make this possible, a biocompatible bone substitute material is placed in the bone defect to stimulate the activity of the body's bone-forming cells. The bone-forming material provides a scaffold for the body's own bone growth. In order for the whole process to proceed smoothly, special collagen barrier membranes are used. They prevent unwanted ingrowth of gingiva (instead of bone) into the bone defect. After suturing the gum, new bone growth/regeneration takes 4–6 months.
What is the sinus lift procedure called “sinus lift”?
The sinus lift procedure is a procedure that regenerates the alveolar bone of the jaw at the site of the maxillary sinus (usually the region of the first premolar and first and second molars in the upper jaw). The implantologist, after incising the gum, inserts the biomaterial under the raised mucosa of the sinus floor through a small window. He then secures the previously created window with a special collagen membrane. Depending on the original thickness of the sinus floor, implants can be placed at the same time as bone regeneration (during the same procedure) or after a period of 6 months (in the case of an extremely thin sinus floor). The sinus lift procedure allows implants to be placed to replace lost posterior teeth in the upper jaw.
