Lack of bone volume in the area of ​​the dental defect is one of the most common relative contraindications to implantation. According to statistics, 70% of dental implants are installed in conditions of jawbone atrophy of varying severity. To solve this problem, many patients are prescribed one or another type of bone grafting.

Bone grafting (osteoplasty, sinus lift, bone augmentation) is an operation to increase bone tissue, which allows you to form a bed sufficient for installation of an implant. In some cases, bone grafting is performed simultaneously with implantation, and in some situations it is separated into a separate operation.

Why is there a need for bone grafting?

The roots of natural teeth are located in the spongy part of the jawbone called the alveolar process. This area of ​​the jaw is riddled with blood vessels and nerves. The parameters of the alveolar processes are not constant values ​​and change under the influence of various factors - the intensity of the chewing load, traumatic tooth extraction, endocrine or systemic diseases of the joints and bones. Let's consider how the lack of chewing pressure affects the jawbone due to tooth extraction.

The roots, thanks to the constant chewing load, keep the alveolar processes in good shape. When one or more teeth are lost, the jawbone in the area of ​​the dentition defect ceases to experience pressure and gradually atrophies. Loss, or resorption, of bone begins several months after tooth extraction and can continue until the original volume is completely lost.

Depending on the location of the defect, bone tissue resorption occurs in different ways. Due to the fact that the density of the tubular bone in the upper jaw is several times lower than in the lower jaw, atrophy of the upper alveolar process occurs much faster. So, if in the lower jaw the process of bone shrinkage starts after 6-12 months, then in the upper jaw – already 2-3 months after tooth extraction.

Dentists distinguish the following types of bone atrophy:

  • The alveolar process is reabsorbed across its width (horizontal atrophy).
  • The alveolar process is absorbed in height (vertical atrophy).
  • Resorption occurs in width and height simultaneously (combined atrophy).

Depending on the direction, degree and localization of resorption, various technologies are used to build up bone tissue for a dental implant. The chosen bone grafting technique, in turn, determines the type of osteoplastic material for bone augmentation.

Materials for bone tissue augmentation during implantation

In implantology, osteoplastic materials are used in the form of granules, bone blocks and porous membranes. There are osteoplastics of mineral (synthetic) and biogenic (animal) origin.

To build up the jawbone during implantation, the following types of bone material are used:

  • Autogenous - a piece of bone extracted from the donor area of ​​the patient himself. The bone placed in the defect area is called an autograft.
  • Allogeneic – the bone donor is another person. Allografts are taken in the event of a person's death, undergo special processing and are stored in donor tissue banks. Despite the ethical issues, allografts have a significant advantage, saving the patient from surgery to harvest his own bone tissue.
  • Xenogeneic – material of animal origin based on bovine or pork bone. Used in the form of granules and bone blocks.
  • Alloplastic - granules of synthetic origin based on calcium phosphate.

A separate group of osteoplastics consists of collagen membrane plates of animal origin. The main purpose of the membranes is to isolate the bone defect from the soft tissue of the gums and actively stimulate the repair of the jaw bone.

Types of bone grafting for dental implantation

To restore lost bone volume and install an implant, 4 technologies are used.

Splitting of the alveolar process

Description of technology: (see the process in the photo below)

the alveolar process in the area of ​​the dental defect is sawed along the ridge with a dental cutter (1). The resulting hole is expanded with drills of different diameters (2,3), after which root-shaped implants are screwed in (4). The remaining cavities on both sides of the rods are filled with a synthetic or natural osteoplastic filler, covered with a resorbable membrane (5), and the gingival flap is sutured.

3-6 months after tissue regeneration is completed, abutments and temporary dental crowns are installed on the implants.

Indications:

This bone grafting technology is used to restore several teeth with horizontal resorption of the alveolar process at least 2 mm thick.

Important:
the method allows for bone grafting to be performed simultaneously with dental implantation, promotes rapid regeneration of bone tissue, and does not require surgery to collect autogenous bone material.

Bone block transplantation

Description of technology:

the operation is carried out in two stages.

  1. At the first stage, donor bone is collected from the chin area, from the cusps of missing wisdom teeth in the upper jaw, and in rare cases, from the ilium.
  2. At the second stage, autogenous bone material is placed in the desired area of ​​the jaw using titanium screws. After this, the regenerated area is covered with a two-layer resorbable membrane and hidden under a gum flap.

Indications:

restoration of one or more teeth with severe bone resorption in width or height.

Important:
using your own bone significantly increases the chances of successful regeneration of the implanted block. This type of bone grafting does not allow you to immediately proceed to implantation. The implant is installed only 6-12 months after the first operation.

Guided bone regeneration

Description of the technology:
(see the process in the photo below)
the gums are opened (1), after which the area is injected with a natural osteo-replacement material based on bovine bone (4). The area is covered with a two-layer collagen membrane (5) to guide bone regeneration and sutured (6). Instead of a resorbable membrane, a non-resorbable film on a titanium mesh frame can be used.

In the photo: Guided bone regeneration simultaneously with the installation of 2 implants

Indications:

used for minor and moderate atrophy of bone tissue in width and height.

Important:
augmentation can be carried out simultaneously with implant installation and does not require surgery to transplant a bone block.

Sinus lift

Description of technology:

During the operation, the dental surgeon lifts the bottom of the maxillary sinus and fills the resulting cavity with a synthetic bone filler. Depending on how the manipulations to correct the bottom of the maxillary sinus are carried out, a distinction is made between closed and open sinus lift.

Indications:

the upper jaw in the area of ​​5-7 chewing teeth with the close proximity of the maxillary sinuses.

Important:
In most cases, implantation in the upper jaw is carried out simultaneously with a sinus lift.

Prices for bone tissue augmentation during dental implantation in Moscow

The cost of the operation is determined by the following factors:

  • Degree of bone tissue atrophy;
  • Selected augmentation technology;
  • Materials used.

A little about the cost of consumables:

Let's give an example of how the cost of augmenting bone tissue for an implant will change depending on the type of materials used.

How to do without bone grafting

The NovaDent dental center offers clients several alternatives to bone grafting. To avoid complications and if there are appropriate indications, we can perform dental implantation without bone tissue augmentation in the following ways:

  • install compression-type implants into deeper layers of bone;
  • install long root-shaped implants at an angle to the plane of the tooth or bypassing the maxillary sinuses;
  • carry out a full jaw implantation on four or six implants.

The choice of treatment method is determined by the attending physician based on the results of the initial consultation and examination of the patient.

About bone grafting of the lower jaw

Implantation is the most advanced and aesthetic type of prosthetics and is successfully used to restore the integrity of the dentition in the absence of one or more teeth.

Often, as a result of various injuries to the jaw, complications after unsuccessful tooth extractions, previous diseases (granuloma, periodontitis) or atrophy as a result of prolonged absence of a tooth, a lack of bone tissue in the jaw occurs. In such cases, it is necessary to build up the dental bone.

Bone augmentation in dentistry helps restore the shape and aesthetically change the position of the jaw tissue, and provides the possibility of successful dental prosthetics by installing an implant.

Gumplasty: what is the procedure and when is it performed?

Gingivoplasty is a microsurgical operation. It is performed under local anesthesia. This operation is performed to improve the aesthetics of a smile, since a smile is considered beautiful in which healthy, straight teeth and gums are visible, the so-called harmony between pink (gingival) and white (dental) aesthetics. There are medical indications for gingivoplasty:

  • uneven gum contour;
  • “gummy” smile;
  • gum recession;
  • prevention of tooth root caries;
  • prevention of the development of periodontal diseases;
  • improvement of tissue structure;
  • treatment of gingivitis, periodontitis;
  • ingrowth of cheek tissue into the gum;
  • exposure of the tooth root;
  • lack of gum volume around the existing implant;
  • implant installation.

Gum recession clinical case

Gingivoplasty is necessary to eliminate soft tissue defects in the root and neck areas of teeth. The operation is performed either after flap surgery or on gums that have not previously undergone any procedures.

Bone grafting at NovaDent clinics

For treatment and restoration of teeth, you are invited by the NovaDent network of dental clinics in Moscow and the region. Medical services here are provided by experienced specialists of the highest category. Modern equipment of clinics, the use of innovative technologies and advanced treatment methods allow them to carry out bone tissue augmentation during implantation with high quality and with minimal discomfort for the patient, minimizing the risk of negative consequences after surgery. Bone grafting in the lower jaw can be performed simultaneously with implantation. This is more comfortable for the patient. But if there is a clear lack of bone tissue, then a separate operation is performed.

Bone material for implantation can be obtained from donor bone from a patient (autogenous) or another person (allogeneic), synthetic (alloplastic) or animal origin (xenogeneic). The price of dental bone tissue directly depends on the type of material used.

The price for bone tissue augmentation in the lower jaw depends on the chosen technology, the material used, the degree of atrophy and is negotiated in each specific case only after a detailed examination by a doctor.
