Tissue Regeneration
Dental Bioregeneration
Many studies have been conducted concerning extraction healing and various pharmaceutical and
chemical applications to modulate the bone and soft tissue response. Extractions are among the
most routine dental procedures and are commonly prescribed in a variety of clinical scenarios like
fracture, non-restorable decay, failed root canal treatments, and advanced periodontitis. Alveolar
bone is a tooth-dependent structure and its shape and volume are determined by dental influences
like morphology of the teeth and tooth position upon eruption. It has been well-documented that
with the removal of teeth, the adjacent alveolar bone undergoes significant atrophy. There are
significant dimensional changes that occur in the early phases of healing, particularly in the first three
months (Ashman 2000; Schropp & Isidor 2008; Tomlin et al. 2014).Bone loss of alveolar ridges after
extraction complicate implant treatment options following extraction. It is essential to have sufficient
alveolar bone volume and adequate tissue contours for a functional and esthetic implant
restoration (Avila-Ortiz et al. 2014; Tomlin et al. 2014).
Prosthetically-driven implant placement in a reduced horizontal bone dimension (whish is essential
for long term implant survival and comfortable implant prsothesis), often results in a peri-implant
bone dehiscence or fenestrations. Bone insufficiencies must be corrected at the time of implant
placement or prior to implant surgery.
Various regenerative techniques, such as non-resorbable/resorbable membrane and titanium
mesh with different size and locations, were used for both horizontal and vertical implant site
developments.
In our bio-regeneration concept; horizontal dimension enhancement relies on the
osteogenetic potential of the periosteum without use of membranes ; we use Growth factors and
Stem cells enriched PRF scaffold instead of membranes. Our technique is based on the so-called
PASS principle that includes;
*primary wound coverage, *angiogenesis,
* space creation, *wound stability.
In our concept we can also augment implant soft tissue contours, horizontal augmentation of peri-
implant tissue thickness for long term stability of the buccal mucosal profile and healthy conditions
of peri-implant tissues.
Dental Bone Graft
Dental bone grafting is a surgical procedure that is used to rebuild or repair the jaw bone. This procedure is commonly used in conjunction with dental implant surgery, sinus lift procedures, and jaw reconstruction surgeries. The goal of dental bone grafting is to provide a strong and stable foundation for dental implants or to repair and rebuild the jaw bone to improve overall oral health.
There are several different types of bone grafting materials that can be used in dental bone grafting procedures. Autograft bone grafting uses bone taken from the patient’s own body, typically from the hip or the jaw. Allograft bone grafting uses donated human bone, and xenograft bone grafting uses bone from animals. Synthetic bone graft substitutes are also available.
One of the most important aspects of dental bone grafting is the use of growth factors, such as Platelet-rich fibrin (PRF) and Bone morphogenetic protein (BMP) to enhance the body’s natural ability to heal and regenerate bone. These growth factors can significantly increase the success rate of dental bone grafting procedures and reduce recovery time.
Dental bone grafting is typically performed as an outpatient procedure, and the recovery time can vary depending on the type of bone grafting procedure and the amount of bone that needs to be grafted. Most patients experience some pain and swelling in the days following the procedure, but these symptoms can usually be managed with over-the-counter pain medication.
The cost of dental bone grafting can vary depending on the type of bone grafting procedure, the type of bone grafting material used, and the location of the dental practice.
In conclusion, dental bone grafting is a surgical procedure that can help to rebuild or repair the jaw bone, making it a suitable foundation for dental implant or improve overall oral health. With the use of growth factors, it can significantly increase the success rate of the procedure and reduce recovery time. It’s important to consult with a dental professional to determine if dental bone grafting is the right option for you.
There are several types of bone grafting materials that can be used in dental bone grafting procedures, including autografts (bone taken from the patient’s own body), allografts (bone taken from a donor), and synthetic materials. The type of material used will depend on the specific needs of the patient and the availability of the material.
The procedure itself is typically performed under local anesthesia, although some patients may also choose to have sedation to help them relax during the procedure. The surgeon will make an incision in the gum tissue to access the jawbone, and will then carefully place the graft material into the area where it is needed. The grafted material will then be covered with a membrane to protect it and encourage the growth of new bone tissue.
Recovery from dental bone grafting can vary depending on the extent of the procedure and the patient’s overall health. Some patients may experience swelling, discomfort, and bruising for a few days after the procedure, and may need to take pain medication to manage any discomfort. Most patients are able to return to their normal activities within a few days, although it is important to follow the surgeon’s instructions for post-operative care to ensure proper healing.
Overall, dental bone grafting is a safe and effective way to restore the structure and function of the jaw after tooth loss or gum disease. If you are considering dental implants or are experiencing problems with the structure of your jaw, it may be worth discussing the possibility of a dental bone graft with your dentist or oral surgeon.
Similar to laparoscopic surgery, only a small incision is required. There is no need to raise the gums, or use complicated techniques with membranes, titanium meshes, or tenting screws. As a result, better outcomes are achieved with less pain, less swelling and fewer complications.
Many complex situations often grafted using bone blocks taken from the hip or jaws in a hospital environment, can now be treated with a simple procedure in the dental office. Implants that have lost bone can now be treated as well. Surgical risks, pain, recovery time and complications are substantially decreased.
About PRF Technique
Dental PRF (platelet-rich fibrin) bone grafting is a cutting-edge procedure that utilizes the patient’s own blood to stimulate the growth of new bone tissue. PRF is a type of fibrin matrix that is rich in platelets, which are cells that play a crucial role in the body’s healing process. By using PRF in a bone grafting procedure, surgeons are able to harness the body’s natural healing abilities to help regenerate bone tissue in the jaw.
PRF bone grafting is a relatively simple and minimally invasive procedure. To prepare the PRF, a small sample of the patient’s blood is collected and then placed in a centrifuge, which separates the platelets from the other blood cells. The platelets are then mixed with a special solution to create the PRF matrix.
The PRF matrix is then placed into the area of the jaw where the bone graft is needed. The platelets in the matrix release growth factors that stimulate the growth of new bone tissue, while the fibrin helps to hold the matrix in place. Over time, the PRF matrix is absorbed by the body, leaving behind healthy, new bone tissue.
PRF bone grafting has several advantages over traditional bone grafting techniques. Because it uses the patient’s own blood, there is no risk of rejection or allergic reaction. In addition, PRF bone grafting is generally faster and less painful than traditional bone grafting procedures, and it has a higher success rate.
If you are considering a dental bone graft and want to learn more about PRF, it is important to speak with an experienced oral surgeon or periodontist. They will be able to assess your specific needs and determine whether PRF bone grafting is a suitable option for you.
