Dental Bridges

Bridges are partial dentures which are fixed as artificial alternative to missing tooth. A tooth bridge possesses false teeth (which are made up of porcelain, alloys, gold, silver or combination of these), crowns on both side of the bridge and teeth supports to place the bridge perfectly in the dental arcade. Dental bridges are permanent and its appropriate approximation and adjustment with the normal teeth should last them for minimum of ten to fifteen years.

Making Dental Bridges

Fabrication of the dental bridge is very technical job and location of the missing teeth as well as material from which you have decided to made it influence a lot in its preparation. Healthy teeth on both sides of the bridge needs some sloughing and finishing before placing a bridge and efforts are made to align it perfectly in place to reduce any future complications. Ante’s Law defines the exact dimensions of the bridge and surface area of the missing tooth should be at least equal or exceed to that of the teeth placed in the bridge. Preparation of the adjacent teeth needs lot of dentist attention because the tissue loss will never be recovered and any undue removal of tissue can create big problems in the placement of dental bridge. Moreover, it is different and obviously very tricky if there’s an issue of missing more than one tooth. Issues regarding approximation and adjustment with reference to the challenges such as masticatory forces and any accidental traumas need to be addressed timely.

Single unit crowns and multiple crown bridges all are designed to stand parallel to the adjacent teeth and proper support from the dental arcade is ensured. Single crowns are fabricated mostly by using Lost Wax Technique while the bigger and multiple units are machined by Computer Aided Designs. In multiple unit structures, dimensions are adjusted properly to develop spatial relationship between the implant and the original teeth.

Types of Dental Bridges

There are three types of dental bridges available in the dental arena. First one is called traditional bridges which involve a pontic (false tooth) supporting the crown of the tooth on both sides of the missing teeth. This is most commonly used in the situations in which one tooth is missing. In this dental bridging healthy teeth are mostly used to place the implant and to fill the gap. Porcelain bonded with metal is used in its preparation. Moreover, in case, adjacent teeth are not very supportive, dental implants would be the next option for the dentists to consider in that particular case. Second type is Cantilever bridges which is applicable in situations where there’s support available from only one healthy side. Third one is bonded bridge which is cheaper and plastic material along with metal support is used in it. These bridges are used where minimum support is required and crowning of the adjacent teeth is also not essential in bonded bridges. Mostly, incisors are bridged by using this technique.

Getting a Dental Bridge Fitted

Multiple dentist visits are essential for appropriate fit of the dental bridge. In the first visit, dentist will anaesthetize the area locally and trim the required area to make room for new crown. Dentist will utilize dental putty for teeth impression which will be used for making the bridge and crown. He will then fit a temporary bridge to protect the surrounding teeth and gums. To make close approximation of the shade, Vita guide can be used for aesthetic fit. In the second appointment, he will remove the temporary bridge and designed bridge will be fitted and checked for all of its functioning. More visits are recommended to ensure appropriate fit.

Among the advantages, aesthetic appearance is one of the leading aspects. It restores the facial expression along with smile. Food apprehension and digestibility is improved because of proper chewing of the food. Masticating forces can be uniformly distributed to all the teeth. Moreover, it also saves adjacent teeth from being molding to any side. Similarly, there are few drawbacks in this dental procedure as well including sensitivities to ambient temperatures for couple of weeks after the procedure. Additionally, vulnerability to the infections is increased because of inappropriate cleaning after placement of the bridge. Healthy tissue loss is also unavoidable in this procedure.

After the procedures, there are strong possibilities for the presence of gaps within and below the bridge so; a complete hygiene plan is essential for oral as well as the body health. Accumulation of debris in these pores and irregular cleaning can lead to many complications such as gingivitis, oral ulcers and many more. Regular flossing of all the teeth and especially the supporting teeth is not a bad idea at all. Some special techniques of cleaning sensitive areas can also be learned from the dentist.
