Implant or crown?
One of the most common problems inDentistry is the absence of a tooth or several for various reasons. The missing tooth can be prosthetic and restore its chewing function and aesthetic appearance. For this, the dentist can offer several possibilities for solving the problem: an implant or a crown is placed on the tooth. What is better, the doctor decides for medical reasons, and the patient - for personal preferences. Turning to the clinic, you can choose one of the options, depending on the factors preceding the situation of tooth loss or the personal preferences of the patient. In order to decide for yourself what type of treatment to choose, it should be understood that it is better - a crown or an implant, and what is the difference between them.
What is an implant?
The implant is an artificial tooth root.from metal, installed surgically on the damaged place, and is intended for fixation of the prosthesis. It has the appearance of a titanium screw with an outer crown. Titanium is one of the few materials with durability and compatibility with body tissues. The crown is indistinguishable from natural teeth and has all their functions. The implant has two parts - intraosseous, embedded in the jaw bone, and periosteal, located above the gum. It is produced in the form of a cylinder with an external thread and is screwed into the bone, and the tooth prosthesis is put on it. When choosing an implant or a crown - which is better, you should rely on your opinion and at the same time not forget about the recommendations of the doctor.
What is a crown?
The crown is the outer shell, fixedon damaged or adjacent teeth. In fact, it is a fixed prosthesis that protects the visible part of the tooth that has collapsed. The appearance of the crown is made as a hollow cap, worn on the tooth and fixed on the root. Makes such a prosthesis dental technician in the laboratory. In the case when the tooth is completely destroyed and absent, the crown is attached to the dental implant or to the adjacent teeth. In general, it is better to put crowns, implants may simply not be suitable.
Types of implants
Choosing which crown to put, implantshould also be considered as an option. They are available in several sizes and shapes. Usually the length can be from 8 to 18 mm, and the average diameter is about 4 mm. According to the standard, the implant consists of a titanium base that replaces the root of the tooth, as well as a crown made of metal-ceramic. The crown is attached to a special attachment (abutment), which rises above the gum.
In dentistry, there are several types of dental implants, which differ in shape, size, implantation method and other properties. So, the main types of implants:
- Root. Used more often than other types.It has the shape of a cylinder or a truncated cone with a thread at the base. The implantation process is quick and easy in the case when the bone tissue is in sufficient quantity, otherwise it is necessary to build bone tissue - sinus lift.
- Plastic. Such implants are implanted when the patient has a bone that is too narrow. They occupy a large amount of bone tissue, so they are used very rarely.
- Plate-root. Combination of two types of implant. It is used infrequently, due to the high complexity of implantation and large dimensions of the structure.
- Subperiosteal. It is used in cases with thinned bone takanya in the patient, besides the design is of large size.
- Mini implant. They have a small size compared to conventional root type implants. They are implanted as stabilizing structures in the presence of removable dentures.
- Implants that stabilize the root system of teeth.
Types of crowns
Depending on the material from whichcrowns are made, they are divided into all-metal, metal-ceramic and all-ceramic. Each type of crown is used for specific clinical indications in each case. Also, the patient can independently choose the option made from the desired material to achieve maximum aesthetic satisfaction from the implant. Cost may affect the choice of material in some cases.
Which crown is better to put on the implant?
Today, the market for dental prostheses is prettywide and produces a variety of crowns on implants. Which is better to use, you can decide based on their classification. They differ in material production:
- Metal ceramics.This crown, the inner part of the frame which is made of metal, and the outer lined with ceramic. This design has high strength, aesthetic appeal and long life.
- Ceramics.Prostheses, during the production of which only one material is used - ceramics. Crowns without metal have better aesthetics. The main type of ceramics used in the manufacture is porcelain or zirconium dioxide. Such structures are durable, highly reliable and have a high service life.
- Metal.Implant crowns are available in solid cast, stamped and gold. This type of crowns can be installed on the molars, because they are hardly noticeable when smiling. The advantage of this type is the fact that under them there is no need to severely undermine teeth.
- Combined. Produced from an alloy of cobalt and chromium when facing the outer part with plastic.
Based on these types of materials, you can choose which crown is better to put. The implant at the same time plays an important but minor role.
What is better to put - a crown or an implant?
There is such a delusion that implants forteeth have an undeniable advantage, such as durability, and put them once before the end of life, despite the fact that the crowns must sometimes be changed. But at the same time it is reliably known that the duration of the operation of the metal-ceramic crown is up to 12 years, and a dental implant will last the same period. And then they both require replacement. Therefore, choosing which is better, implant or crown on the tooth, should not be guided by this principle.
На самом деле это довольно сложный вопрос - о that is better, crown or implant. Reviews of patients who installed the crowns, and people with implants differ. That is, it all depends on the individual characteristics of the problem being solved and the personal wishes of the patients. So, when choosing a particular type of restorative tooth treatment, first of all, attention is paid to the degree of destruction. In the case when restoration is possible on half of the tooth, it is sealed, and in case of severe damage it is covered with a crown.
At the same time choosing which is better - a crown orimplant, it is necessary to remember that the latter option requires undercuts of adjacent teeth. After all, when it is installed, the implantation takes place in the jaw bone, and the crowns are attached to adjacent teeth. Therefore, choosing an implant or a crown - which is better, should take into account the condition of all teeth.
Contraindications to implantation
Such a seemingly simple procedure as implantation has a number of contraindications. After all, in fact, this is a surgical procedure, which is not recommended when:
- diseases of the blood and blood-forming organs (poor blood clotting);
- congenital and acquired diseases of the central nervous system;
- tumor formations of various organs and systems;
- reducing the efficiency of the immune system;
- systemic diseases of connective and bone tissues;
- tuberculosis in various forms and trends;
- diseases of the oral mucosa;
- abnormalities in the endocrine system (diabetes mellitus);
- increased tonus of the masticatory muscles.
Also a contraindication may be intolerance to the components of the implant.
Complications
When the implant is implanted, some complications may occur either immediately after the operation or after some time. It can be:
- perforation of the maxillary sinus of the nose with insufficient formation of bone tissue;
- damage to the nerves of the mandible;
- bleeding with hematological abnormalities;
- pain in the first hours after surgery;
- the discrepancy imposed seams;
- development of inflammatory processes and infectious infections of the surgical field;
- wrong position of the implant in the bone, making it difficult to continue the operation.
These complications may not occur if you choose the right doctor.
Going to the dentist's appointment, the doctor canAsk a logical question - whether an implant or a crown, which is better. In this case, the dentist should not only rely on medical indications, but also take into account the personal preferences of the patient. Choosing which crowns are best placed on implants can also be based on their cost, because low-cost models cannot be made of high-quality material.
