Your dental treatment quality depends not only on the knowledge and skills of the dentist but also important are the instruments in use. That is why we are constantly trying to keep up to date with the increasing regulations and track all the latest dental equipment producers. The most important aspect in this area is the ability to be well informed. We are capable to achieve that by the best edition of dentists for dentists “Reality”, which updates monthly and does not have ads of dental products. All of our items are 5 or 4 stars rated.
We stick by this rule for equipment selection – to have the best quality and be proven for long work life (at least a couple of years), in order to avoid unwanted late side effects.
There is two basic systems for teeth whitening – in the dental office and home. They consist of a general approach – disintegration of particles (hydrogen) to split molecules of oxygen. These free radicals have huge impact in extracting particles in enamel in order for the teeth to be whitened. That is why we do not want two things to happen – using pharmaceutical items with ordinary templates of cream; second – systematic use of toothpaste with soda – that way there is excessive amount of free dangerous radicals. These radicals are factors in developing tumors, cardio vascular diseases and many others. Such an attempt must be supervised by a dentist. In both cases of whitening (home or dental office) there is different concentrations of two peroxideс, we work only with approved by the American Dental Association materials. Treatment in dental offices with high percentage of peroxide with argon laser and bright light and last hour and a half. Domestic systems are daily and nightly (8 hours), but daily ones are more aggressive. A dental cream is put in individual braces made by patient”s teeth layers. The major reason for the peroxide to disintegrate to highly active oxygen lays in human saliva and its enzyme content.
Modern golden standard for quality is adhesive dentistry (bonding) “Vedra Dental” makes no exception. We work primarily with composite materials and amalgame(mercury+silver) is not in use. A bonding system consists of etching, a bond(a liquid component) and composite, and finishing and polishing kits. Etching makes use of the natural layers of teeth under enamel and strengthens them multiple times by acid reaction and prepares every surface for nest step.
Adhesive (bond) is applied with a special thin brush. Its main role is to get the enamol end dentin so that they connect with the filling that is gonna by put in place. This process is successful in new dental systems. The polymer that is applied on teeth layers reacts chemically with them. This method helps prolonged life of photopolymer fillings – it does not fall. More they are created by the physical properties of the teeth tissues. This ensures that these materials can be placed anywhere, without damaging teeth tissues. Used materials can recover broken tooth where the shape, strength and the force of the bite are quite unpleasant. Composites have natural teeth color and are polished so they shine. Especially micro composites that are used for front teeth, because they have smaller particles and aesthetics and natural look are important part of the process. Hybrids are used for back teeth – they have bigger particles but are less responsive of huge digestive movements.
Sometimes working on sensitive teeth requires applying glass ionomeric pad in thin layer which protects the pulp of the tooth from unwanted damage. Often unpleasant over sensitivity when drinking cold liquids.
Treatment of broken teeth requires use of chemical polymers. Kids teeth and some tooth decays require glass ionomeric concretes because they do not take long time to be placed.
Root canals are mechanically and chemically treated but sometimes medical medicines are required.
Cases of reversible pulpit can depend on photopolymer calcium hydroxide creams for isolating uncovered parts. Old manual and mechanical systems do not have vertical scraping ability that uses clockwise and not clockwise movement but new ones have. That ensures the root canals are completely clean which is vital for the dental treatment to have effect. Most capable are nickel-titanium instruments which bend and return shape easily. This helps also unwanted breaks to be avoided.
Root treatment requires chemical interference that consists of many parts but two are vital – dissolving organic tissues and inorganic treatment. There is a group of substances specially oriented in dissolving old root fillings (in the past this method consisted of using eugenol and resorcinol fillings which are still widely used in Bulgaria but are rejected by modern dentistry because they cause allergic reaction and fade away with time leaving root canals empty.)
Medicines are injected temporarily in roots to help local prevention of processes that patients organism is not capable to cope with alone.
Modern endodontics makes use of root filling items without medicines but they take advantage in fully enclosing canal systems. They consists of epoxy resin and are insoluble which helps them to be durable filling. These filling combine with special pins which are conical and can yield so the root canals can be completely compact.
Often after filling treatment it is required for the tooth to be recovered with the purpose of calibristic pins which are mounted. Most common systems are titanium, golden ones are less in use. They retain in the upper part where artificial tooth is created by dentist.
This constructing of the part that is over the gum uses materials which are not the same color as the teeth (for example blue), which makes life easier for the dentist. They are composites which are self hardening or double hardened and have huge adhesive strength.
Cleaning tooth calculus can be executed using two systems – manual and mechanical. First method requires metal equipment with bend and sharp top part. These items can penetrate deeply and are used primarily by dentists when performing parodontic curettage. The mechanical system is universal way and is widely accepted more by patients, but it helps early stages of parodontical diseases because it has bigger tops and can not perform deeper cuts under gum. The combination of water and vibration is what makes the second way unique. Micro vibrations of bend titanium apex contribute to water molecules to spread and this energy results in easy removal of hard build ups. After this treatment surfaces are polished to prevent new build ups on the same spot. This process is extremely important for exposed root surfaces which are more rugged.
If build ups are not as aesthetic as much as large (smokers), can be cleaned by special rotating items like the mentioned above.
It is of great importance here that information to laboratory is delivered accurate and this depends on several factors. From material point of view – mostly imprint material and also information from imprint spoon, retraction cords, hemostatic cream (prevents blood flows). A-silicons are mediators because they are hydrophilic and harden in 2-4 minutes. Usually thick mass take turns with thin one. Another way of executing this process is simultaneously placing these masses. This and many other details represent the final imprint and predictable results. This method is generally used for all constructions made by dental laboratory, from inlay to final prosthesis.
Major factor in preparations of crowns, bridges and many more are dental grinding machines and their specific shape. For circular thresholds in crowns we use number of borers, most of which are truncated cone shaped. These items can grind with their whole surface, only top, side grinding, depending on their diamond coating or thread.
After laboratory sends fixed constructions they are placed permanently by different concretes with huge strength. Most strong pasting occurs in identical surfaces and concretes are just a mediators. Modern concretes are generally glass-ionomers and resin concretes. There is a borderline case – it is resin-ionomers which combine both. Constructions made of metal upon the teeth surface are placed by choice – by self polymeric concretes. All ceramic constructions require resin concretes but veneers and thinner inlays made of ceramic allow pasting even with photopolymeric concretes (strongest concretes) because they are thin enough to let through lightning from a dental lamp. Vital moment of veneers design is the similarity between the color of the tooth, the veneer and resin concrete.
Temporary constructions can be made by а dental mechanic or in dental office by imprinting before teeth grinding. Material hardens in 2-3 minutes, can be in natural teeth color and ensures patient can leave with His teeth, without noticing dental care. This mechanisms and permanent constructions also are placed with temporary concretes. Recommended are non eugenol, because eugenol can unstimulate the polymerization between resin concretes. These materials ensure durability and are also easily taken down in dental office. For description of materials of every prosthesis constructions, go to LABORATORY.
