A Prosthodontist is a dentist who has completed an accredited specialist training programme, usually a minimum of an addition of three years duration, to ensure a high level of expertise in this field.
Prosthodontics is the field of dentistry that relates to rebuilding natural teeth and restoring missing teeth with prosthetic replacements to achieve the best possible functional and aesthetic outcome. This can range from a routine single crown for a damaged tooth or it could involve more complex procedures, such as full mouth reconstruction of damaged or mutilated dentitions and implant dentistry. In the majority of cases the job of a prosthodontist lies somewhere between these clinical situations.
The specialist training of a Prosthodontist also involves knowledge of other dental specialities to enable co-ordination and integration of a patient’s treatment plan with other specialists ensuring the highest level of care.
A dental crown or dental cap is a custom made restoration that covers a tooth with sustained significant loss of structure. Dental crowns are used to restore teeth to a certain shape and size. They provide strength and improve the appearance of the tooth.
There are three basic types of materials for dental crowns:
Dental bridges literally bridge the gap created by one or more missing teeth. A bridge is made up of two crowns for the teeth on either side of the gap -- these two anchoring teeth are called abutment teeth -- or a false tooth/teeth in between. These false teeth are called pontics .Dental bridges are supported by natural teeth or implants. Dental bridge can be made of metal, porcelain fused to metal and metal free bridges.
Complete dentures or Full dentures are used when all the teeth are missing . Complete dentures can be either "conventional" or "immediate". The framework of complete dentures may be made of resin, metal or a combination. The most latest top of the line are BPS complete dentures.
BPS dentures: BPS® stands for Biofunctional Prosthetic System. These Dentures are ‘Top of the Line’ precision dentures that provide optimum function while eating, speaking or laughing. They feature the best teeth and plastics money can buy.
By far the best part of BPS® Dentures are the use of the SR Ivocap processing system. This unique system uses continuous heat and injection moulding to produce dentures that are comfortable and functional. The acrylic is injected under pressure and during the curing process which produces a denture without shrinkage and warping which can occur under regular processing.
Ivoclar teeth such as “SR Vivodent PE” are natural like teeth that recreate the character of your smile. They are made of multiple layers of double cross linked acrylic reins that contribute to their life like appearance and well known resistance to wear.
Attachment retained overdentures
Most patients who have complete dentures are dissatisfied with the limited retention and stability of their prostheses. Over-dentures provide excellent retention and stability. There are broadly two types of over-dentures - Tooth supported and implant supported.
Tooth supported overdentures gain their retention and stability from the use of attachments. Attachments are simple connectors consisting of two or more parts. One part connects to the root and the other part to the over-denture acrylic denture base.
The rationale for using tooth supported over-dentures is
Partial dentures or Cast Partial Dentures
Removable Partial Dentures with cast metal frameworks offer numerous advantages over the conventional partial dentures commonly used. The frameworks of these dentures are cast to fit the teeth. Since they sit on the teeth, as well as being attached to them, they are extremely stable and retentive.
The teeth have to be altered slightly beforehand in order that the partial denture can rest upon them without interfering with the way the patient bites the teeth together. Because the teeth are altered beforehand, there are fewer limitations in the placement of clasps, and they are less likely to be seen than the wrought wire clasps of the conventional treatment partial denture.
Modern frameworks are cast from an extremely strong alloy called chrome cobalt which can be cast very thin and are much less likely to break than the all plastic variety. They are also much less noticeable to the tongue.
Full mouth rehabilitation
A complete makeover of your mouth, bite and smile to give you healthy mouth and renewed feeling of confidence. A team of specialists work together to restore the function and appearance of the teeth. To correct relationship between gums, bones, muscles, and teeth. This full mouth rehabilitation is highly successful with our careful planning and treatment sequencing. Anyone with short, worn teeth or those that are chipped and broken throughout the mouth would be an excellent candidate. Combining the science of Neuromuscular Dentistry with the artistry of Cosmetic Dentistry, Full Mouth Rehabilitation creates a smile that is functional, comfortable and beautiful.
Sometimes, a tooth is planned to be restored with an restoration, but the decay or fracture is so extensive that a direct restoration, such as composite, would compromise the structural integrity of the restored tooth . In such situations, an indirect gold, metal or porcelain inlay restoration may be indicated.
Advantages of an inlay are when an inlay is used, the tooth-to-restoration margin may be finished and polished to such a super-fine line of contact that recurrent decay will be all but impossible.
While these restorations might be twice the price of direct restorations, the superiority of an inlay in terms of resistance to occlusal forces, protection against recurrent decay, precision of fabrication, marginal integrity, proper contouring for gingival (tissue) health, and ease of cleansing offers an excellent alternative to the direct restoration.
Maxillofacial Prosthetics is a subspecialty of Prosthodontics that involves rehabilitation of patients with defects or disabilities that were present when born or developed due to disease or trauma. Prostheses are often needed to replace missing areas of bone or tissue and restore oral functions such as swallowing, speech, and chewing. In other instances, a prosthesis for the face or body may be indicated for cosmetic and psychosocial reasons. Prosthetic devices may also be created to position or shield facial structures during radiation therapy. Patients that typically desire prosthetic care are those that have been in an accident, have had surgical removal of diseased tissues, or have a neuromuscular disorder. Children can also be born without full development of ears, teeth, or palate and need specialized care. The overall goal of all maxillofacial prosthetic treatment is to improve the quality of life. Often these prostheses are combined with traditional dental therapy to restore health, function and esthetics to the oral cavity.
A 20 year old man reported with multiple scaring of the scalp and the face. He had suffered a chemical blasat injury and lost his nose ear and significant portion of scalp, face and the hand. A thorough examination was done and a facial rehabilitaion with silicone material was planned. The hand was also made with acrylic and stained to get the proper colour match.
A precession attachments is precession machined key and lock housing that connects a removable partial denture to fixed bridge work or natural tooth to an implant. The key way part of the attachment is soldered to fixed crowns or bridge work. The key part is attached to the partial denture.
The precession attachments are also used in implant dentistry in rare cases where it necessitates to connect natural teeth to dental implants.
