只有当患者得到的修复结构不仅耐用,而且舒适时,才能谈得上成功的假牙修复。反过来,为了确保最大程度的舒适性,有必要最大程度地保证义齿的真实性。尤其重要的是,要在义齿中保留上下牙齿的咬合面特征--咀嚼面和切缘。
确定患者下颌的正确方向和轨迹以及矢状曲线和横向曲线方向的常用工具是面弓。在应用过程中获得的数据被用来制作印模,技术人员根据这些印模制作假体。然而,如今已经开发出了更现代化、更高效的设备--HIP平面分析仪,ROOTT的矫形牙医们正在使用它。
由于牙科技术的进步,几乎可以修复任何缺损的牙列。最重要的是根据您的具体情况选择合适的假牙修复方法。一名合格的牙医一定会为您的临床病例提出最佳的假牙建议。牙医有很多选择--修复学在不断发展,新材料、新方法和新技术层出不穷。
假牙种类假牙修复体可以是活动的、固定的或固定的。大多数情况下,选择取决于需要修复多少颗牙齿。因此,每一组都有自己的设计品种。
活动义肢这种假牙通常用于缺失大量牙齿或完全丧失牙齿的情况。根据这种情况,活动假牙可以是全口假牙,也可以是局部假牙。两者都由基托和人工牙齿组成。局部假牙有固定元件。

" - Doctor, my crown on my tooth is wobbling, what should I do?" Such a question is not uncommon in the dental office. Not always patients understand why, instead of just fixing the crown, the doctor appoints an examination.
The task of the prosthodontist is not just to fix the prosthesis, but to find out the reason why the crown wobbles after installation.
Without examination, it is impossible to make an accurate diagnosis, and if the cause is not eliminated, the problem will occur again and again.
What causes the crown to wobble?Part of the dental examination is the collection of anamnesis, especially if the prosthesis is several years old and with the problem you came to the wrong doctor who installed it.
The fact is that there are objective causes of crown loosening.
Dental cement changes its structure over time, and its adhesive (bonding) properties are lost. Crowns on the front teeth are particularly pron…

Speaking of high technology, everyone involuntarily imagines innovative developments that allow you to solve a problem or task as quickly and efficiently as possible. This is exactly what patients expect from modern methods of tooth replacement when they go to the dentists with a tooth that has been destroyed or needs to be extracted. And since unfortunately no way to grow a new tooth has been invented yet, let's take a look at new and proven tooth restoration systems.
Question:
What modern method can be used to restore 2 consecutive extracted teeth. Bridge - do not suggest!
Answer:
Unless you are considering a bridge, the most effective method would be implantation with the ROOTT system.

An artificial crown is placed to strengthen the crown part of the tooth, extend its life, and mask cosmetic defects. The crown needs a support: your own tooth, an inlay or an implant. Crowns are fixed prosthetics, they are designed to restore the tooth row, restore the beauty of the smile and fully participate in the chewing process. Unfortunately, there are situations when a patient discovers that the crown has fallen out. Why does this happen and what is the algorithm of actions if this happens?
Causes of dislocationProsthetics is a process that involves 3 people: the prosthodontist, the dental technician and the patient. Each of them determines how long the restoration will last.
The dentist is responsible for making sure the tooth is properly prepared. The main causes of misalignment are due to improper preparation of the tooth:
The taper of the stump exceeds 30 degrees (it is too sharp) The height of the prepared tooth is very sm…An unpleasant odor from under the crown of the tooth indicates that food residues have gotten under the restoration. They decompose, multiplying the number of bacteria daily and hourly. Pathogens penetrate the hard tissues of the tooth, because the tooth is ground down and there is no protective barrier. The hard tissue begins to rot. In most cases, teeth are depulped before dentures. They remove the nerve-vascular bundle, the pulp, which in its intact state signals problems with pain. Without the pulp, pain is absent and it is not uncommon for caries to completely destroy the hard tissue.
Symptoms of infection may be only sudden loosening of the crown due to tissue loss and a putrid odor.
Causes of tooth odor under the crownMost often, it is incompetence of the doctor. The desire to save money can lead to a small dentistry with an inexperienced doctor. This, in turn, affects treatment planning, tooth preparation, taking impressions, determ…
Tooth extraction is a surgical procedure that cannot be performed without damaging tissue and blood vessels. This causes bleeding from the tooth cavity. The blood forms a clot that protects the wound from bacterial invasion. Usually, it stops discharging from the wound after a few minutes, but there are cases when bleeding continues for hours or even days.
Causes of bleeding from the hole of the extracted toothIn dentistry, there are general, local and mixed causes. Bleeding can occur due to a doctor's error, non-compliance with the recommendations of the patient or taking medications to treat common diseases.
Local causes Rupture of blood vessels during traumatic surgery; Breakage of the root septum or alveolus (hole); Inflammation in the area of the tooth that was extracted; the action of adrenaline (after the constriction of blood vessels, there is a second phase - their expansion); melting of blood clots blocking the vessels under the in…Reading time ~ 2 min Number of readings: 2198
The first question when a patient is given the verdict of having one or more teeth extracted is the question of prosthetics. Replacement dentistry techniques offer a spectrum of approaches in terms of fixed and removable restoration. A patient planning dental prosthetics understands the differences of each method and studies reviews about them
Before choosing a restoration option, make sure that you have no prohibitions to dentures with this method. The doctor is confident in the effectiveness of the technology used, and in the safety for a particular patient.
For the most part, the prohibitions are relative. They are removable, and relate to the installation of fixed prostheses (crowns, bridges).
Classification of contraindications is quite simple, namely, "prohibitions" are divided into local and general. Let's consider their essence …

The question of whether to place a crown is relevant when there are alternatives in terms of restoration.
Question:
I have only a stump left of my bottom tooth. Although the root seems to be normal, at least six months ago it did not inspire fear. Is it possible to make a prosthesis or extract and put an implant.
Answer:
If the root is strong, put a post in the root canal as a base for a crown. Implantation is an effective solution.
Question:
I had a root resection on my upper four three years ago. At first there were no problems, but recently the tooth started to crumble. Is it possible to put a crown on it?
Answer:
If the tooth is held on only half of th…
