Filling: in case of smaller cavities
Forming of cavity is performed by a high-spin, while the removing of decay is carried out by slow spin drill. Subsequently, the anatomic shape of tooth is restored by tooth-coloured and aesthetic filling material. The intervention could be implemented with using a so-called cofferdam isolating set, which consists of rubber sheet and fixing clip that is a useful as it provides maximal overview and security and adequate sterile conditions for the intervention. Teeth are seized through holes on rubber sheet. Sheet is fixed to tooth by clip and remains outside of mouth with utilising a frame. Height is checked and adjusted and the final polish is done with rubber polish and polish paste as last steps.
Subsequent to removal of old filling and cleaning of cavity, special cavity transformation is performed. In various cases, the cusp needs to be removed as it is a part lacking support and might brake off due to occlusal force (in case of rootcanal-treated tooth the tooth is covered by onlay including cusps). The so-called undergoing parts of the cavity could be filled with composite material and then an impression of tooth is taken. Impression-taking is performed with silicon based impression material: the impression tray is filled and then placed onto the dental arch with pressure. The antagonist impression taking, namely the impression of the opposite arch of the treated arch is required for dental technician work. In such case, alginate impression material is used most commonly.
A temporary inlay may be placed in the tooth to provide solution until finishing dental laboratory work. A more simple solution is the use of light curing temporary filling.
Inlays are prepared in the lab over 3-4 days. Prior to fitting the cavity is cleaned by antiseptics. The cavity is then conditioned to enable proper chemical bond by special adhesive to the inlay. After bonding, polishing and height adjustment is carried out.
Crowns are necessary if your tooth is massively damaged by decay or fracturethat a restoration would not hold anymore. According to how much of the tooth has become friable, the dentist will recommend a partial crown or a complete crown.
Crowns are manufactured by the dental technician on teethpreviously prepared bythe dentist on the basis of a precise impression.
The finished crowns integrate functionally and aesthetically into the existing teeth. If there is not enough tooth substance available for the production of crowns (e.g. in case of broken or root-canal treated teeth), a construction of the corewith restorative material and/or a metal post becomes necessary.
Crowns can consist of various materials: metal alloy, synthetic or a metal ceramic mix. Crowns that only consist of ceramic have not been considered break-proof enough up to now in the posterior area (molar and premolar teeth).
Metal-ceramic crowns are the ones that are most commonly used. For improved esthetics, full ceramic crowns can be applied to front teeth, and zirconia based crowns crowns may be used in the posterior area.
A bridge is a fixed dental device to fill gaps caused by tooth loss and thus affects the function and aesthetic of the row of teeth.The teeth neighbouring the gap are prepared for crowns, and these crowns hold the artificial tooth that fills out the gap. . The combination of aesthetic and biomechanical function is focused here.
The framework of such bridges can be made out of nickel free dentalalloy or noble metal alloy (platinum, gold). According to that we call these bridges metal porcelain – or gold porcelain crowns. In case of these types several teeth can be replaced, which means that long links are possible. The maximum length amounts 14 links, where a lot of teeth can be replaced. The exact number of the teeth to be replaced is dependent on the position and the constitution of the existing teeth.
The stability of Zirconium bridges is comparable to the one of the metal porcelain or gold porcelain crowns. But they however answer far higher aesthetic claims. This solution generally is the most optimal one and is highly recommended to patients.
If there are already a lot of teeth missing and the remaining teeth are no more capable of holding a bridge, implants have to be used for anchoring the bridge. At this the abutments screwed on the implants assure the anchoring of the bridge. The bridge is either produced to be screw-retainedor to be applied with cement.
Teeth are prepared by the dentist to a special shape. Decays and damaged areas could be restored, which is called a core build up. Root canal treated teeth usually need a root canal post and core to support the crown. Impression taking is required after the preparation of teeth (see inlay). In case of long bridges, a separate session of gnathological measure-taking may become necessary for the harmonic occlusion of lower and upper dental arch.
A temporary crown or bridge is fitted right after the treatment in the office. In case there are several weeks until receiving the final bridges or crowns (e.g. healing term of inflamed gum), we provide a long term temporary bridge or crown made in the dental technicians’ laboratory.
The colour, shape and precise fit of the crown or bridge is checked upon handing over. In case they are adequate from aesthetic and functional point of view, fitting is performed. Height correction is performed in this or in further meetings.
Getting used to crowns or bridges may take some weeks, even months. Height adjustment and correction may be needed several times. Subsequent to attachment, vital teeth may be sensitive to cold and warm and chewing function may decrease, however, it passes after a certain amount of time. This period of time depends on the individual. However, you shall inform our dentist of all symptoms as should you experience intense pain that does not fade away, contact our dentist.
Dental care at home includes the proper use of tooth brush and paste, and, moreover, the regular use of interdental brush and dental floss. You shall request the opinion of dental hygienist (dental hygienic consultation) in all cases and clean your teeth obeying his/her advice.
