This term describes any surgery carried out inside the mouth, and ranges from minor procedures to more complex operations that may require hospitalisation. The oral surgeries available are:
Teeth that are "impacted" are unable to erupt fully into the mouth. Some impacted teeth are completely covered by overlying bone and gum, while other teeth partially erupt into the mouth but are prevented from erupting fully by the overlying bone, gum, or adjacent teeth.
The teeth that are most commonly impacted are the third molar or "wisdom" teeth, which frequently are unable to erupt into position when all the other teeth are present. They may play a role in causing crowding of teeth, especially the lower front teeth.
Impacted teeth are best removed in the teens or early twenties, as the surgery is easier before root development is complete and healing is more rapid in younger patients. When removal of impacted wisdom teeth is delayed to a later age, complications are more likely.
Impacted teeth are removed as they cause a variety of problems such as:
A past history of difficult tooth extractions, or fracture of a tooth below the gum during attempted extraction, usually requires a surgical approach to remove the tooth or tooth root from the jaw. In these situations general dentists may sometimes refer patients for this surgery. Benefits to the patient are having the surgery carried out by someone with extensive experience in this area. This usually makes it a more acceptable experience.
Surgery to assist orthodontic Treatment
Orthodontic treatment is concerned with straightening crooked teeth and correcting abnormalities of the bite, and undertaken by dental specialists called orthodontists. To assist with such treatment, orthodontists sometimes request surgical procedures which may include the uncovering or removal of unerupted teeth, or other more complex forms of surgery (see "Jaw Surgery" under Maxillofacial Surgery).
This term refers to surgery undertaken in order to improve the ability to wear full dentures, for patients who have suffered loss of the bony ridge (alveolus) on which the denture sits. Following removal of all the natural teeth, there is a steady absorption and shrinkage of the alveolus, and after many years it may become almost impossible to wear a denture. Surgery to improve the size and shape of the alveolus includes both simple procedures to remove excess loose gum, and more complex operations involving bone grafts and skin grafts. However many such patients can now have their needs met by placement of dental implants.
This term refers to more major surgery carried out on the jaws and facial bones, or their associated structures, for a variety of reasons as described below. Such surgery can often be carried out working entirely through the patient's mouth, although certain operations require small skin incisions that can usually be placed in positions where they are not readily visible. The range of surgery includes:
Surgery (Orthognathic Surgery)
Surgery to correct the size and shape of the jaws is a relatively common procedure, usually done in conjunction with orthodontic treatment to align the teeth. The maxilla (upper jaw) or mandible (lower jaw), or both, may require surgical correction to treat jaw deformities resulting from either developmental problems or following serious jaw injuries.
The aim of such surgery is to provide a correct bite of the teeth and a normal facial appearance. Orthognathic surgery (jaw surgery) is carried out in hospital and usually requires a stay of 1-3 days. Following surgery, the jaw bones are fixed in their new positions using small bone plates and screws (internal fixation) while healing takes place. This technique allows normal function of the jaws soon after the surgery and has eliminated the older technique of wiring the upper and lower teeth together until healing is complete.
Oral and maxillofacial surgeons usually treat fractures of the facial bones following motor vehicle accidents, assaults and other accidents. Most of these patients will be treated in hospital after being admitted through Accident Departments. The treatment of these injuries has become very sophisticated in recent years, using similar techniques to those developed by oral and maxillofacial surgeons for the surgery of jaw deformities.
Small titanium plates and screws are used to meticulously repair the fractures thus ensuring a correct bite of the teeth, normal function of the jaw joint, and restoration of facial appearance. Extensive training in dentistry is an essential part of being able to undertake such treatment.
Jaw surgery may be carried out to improve facial appearance. The most common operation is surgery to the chin (genioplasty), particularly for receding or over-prominent chins, in which size and shape may be permanently modified to provide a balanced facial appearance. Correction of asymmetry (crooked jaws or faces) can also be undertaken, as well as a range of other facial deformities.
Cleft lip and palate may affect about one person in 800. Following primary repair of cleft lip and palate, during the fist year of life, oral and maxillofacial surgeons are subsequently involved in treatment of associated secondary defects of jaw growth and residual palatal clefts and this surgery is undertaken during the early teens. The most common operation is forward movement of the upper jaw to correct both the bite and facial appearance. Associated with this it is usually necessary to place bone grafts, most commonly taken from the hip, into the remaining palatal cleft.
Disorders of the jaw joint (the temporomandibular joint or "TMJ") are relatively common and may arise for no obvious reason or following a jaw injury. Such disorders are frequently associated with clicking and locking of the joint, while significant pain may also be a feature. Management does not normally require surgery except in a very small number of cases, with most patients responding well to a variety of conservative treatments.
