Bone tissue augmentation and repair in the required volume.
Do you want to maintain a beautiful smile? Definitely! But this requires a solid foundation. The upper and lower jaws are the foundation which forms your beautiful smile, providing a stable supporting structure for teeth and facial features. Defects in these bones can radically change your appearance over time.
The term osteoplasty is also used.
This procedure is recommended in the absence of bone tissue. This condition can develop after periodontal disease, tooth loss or injury. Osteoplasty is also used to prepare the oral cavity for dental implantation.
STAGES OF TREATMENT
It includes oral cavity sanation, preliminary administration of antibiotics, and, if necessary, replacement therapy.
Anaesthesia of the jaw (local anaesthesia).
Access to the gums and bones. The placement in the cavity of the bone material and fixing it with mini-screws.
Covering the site of surgery with a barrier membrane. Suturing the gums.
Administration of antibiotics and painkillers after the surgery. Stitch removal.
Indications for bone grafting
Bone grafting in dental implantation is a common procedure. If the bone tissue is of insufficient thickness or height, it is impossible to fix the implant securely. Resorption of bone tissue occurs in the absence of masticating pressure on the jaw. In case of severe bone loss, even the structure of the face is destroyed. A decreased lower third of the face and a decreasing distance between chin and nose are visual signs of premature ageing.
The surgeon or dentist recommends bone grafting only after a thorough examination and 3D diagnosis.
The bone grafting in dentistry can be performed in various ways. The PORCELAIN Clinic uses the following osteoplasty technologies:
- - Sinus lifting (closed or open). As a result of the procedure, the sinus floor mucosa is displaced. The cavity above the bone is filled with artificial material. The surgery is necessary in case of a lack of bone level. The whole length of the implant should be in the bone structure
- - Increase in bone width. In this case, alveolar ridge splitting is usually used (cutting it into two halves). After the surgery, the inner part is naturally filled with bone. It becomes possible to place the implant simultaneously with the ridge expansion. As a result of this method, bone growth occurs most rapidly. The reasons are the presence of blood vessels and growth cells in the spongy structure of the alveolar process.
- - Guided bone regeneration. This is the least traumatic way to augment bone structure. The procedure is used to increase both the height and width of the bone level. In this case, two components are used — bone grafting and installation of a barrier membrane. At the same time, implantation may be performed. Collagen membranes for bone regeneration are also used after tooth extraction. The membrane does not allow gum cells to fill the alveolar socket. Often at the same time, the bone material is grafted. As a result, the cavity is filled with bone tissue, the volume is preserved, and it is possible to subsequently place a dental implant.
- - Bone block grafting. With this method, an implant is often required to be taken from the patient — usually in the area ofthe chin or posterior part of the jaw. After fixing the bone block with microscrews, a biocompatible barrier membrane is installed. The bone block grafting gives a predictable result. It is impossible to place implants simultaneously. In addition, it takes a long time to heal — 6–8 months.
After bone augmentation, antibiotic therapy is performed. For some time, the patient should refrain from taking solid food, playing sports, sneezing, loud coughing, air travel and activities which increase body temperature and blood pressure.
Bone material selection
Usually, the doctor offers options for bone material, but the patient should make the final choice. There are the following types of bone graft:
- - Autografts.With this technique, bone is taken directly from the patient’s body. Autografts are perfectly compatible. They successfully grow together. The disadvantages are the need for the second surgery and the painful procedure.
- - Xenografts. They are obtained from animal bones, usually cows. In this case, appropriate treatment is performed to ensure sterility and biocompatibility. The advantages of this material are the need for only one surgery, as well as a relatively easy and quick recovery.
- - Allografts. These materials are taken from human donors after their death. Bones collected in this way are sterilized and tested for safe use. Moreover, only one surgery is required. However, there is a risk of immunogenic responses.
- - Alloplastic implants. They are synthesized bone material (gypsum, biocoral, bioglass, etc.). Such materials can be of various sizes and shapes for better fitting; they do not cause implant failure and are biodegradable.
- - Combined implants. They combine the components of the above groups.
Contraindications to bone grafting
The surgery is contraindicated in the following cases:
- - autoimmune diseases;
- - exacerbation of chronic diseases;
- - blood diseases;
- - inflammation of the mucous membrane of the mouth or nasopharynx;
- - pregnancy or breastfeeding.
Doctors who perform this surgery:
- - Surgeons.
- - Dentists.
Bone grafting: price
The cheapest method of osteoplasty is the alveolar ridge splitting. In this case, no expensive bone materials and membranes are required. The method of collection and bone block grafting are usually of the highest price. The guided bone regeneration and sinus lifting are usually of medium-price. The type and quality of the materials used, the need for preliminary diagnostics affect the price of the procedure.
The osteoplasty will eliminate the defect or cavitation in the jaw bone. After installing the graft material, it is replaced by your natural bone. The positive effect lasts forever. The surgery leads to the restoration of the functions of mastication and the person's appearance, and allows to install implants. Oral health, a beautiful smile and well-being are returned to the patient.

We often encounter situations where the patient’s teeth are even, have a good color and form, but on one tooth or two the gums seemingly “jumped up” or “dropped”. Then a major differential forms that seriously ruins the smile. In such cases, we advise you have plastics put on your gums to return the to their natural level.
