Canine Exposure Surgery – A Detailed Study

on February 26, 2022

Canine Exposure Surgery: An impacted tooth is one that does not entirely or even partially erupt. Canines, along with third molars, are among the most often impacted teeth. The impact may occur on either the labial or palatal side of your jaw. Those to the palatal region occur twice as frequently as impacts to the labial region. Females are twice as likely as guys to be impacted. Maxillary canine impaction is predicted to afflict 0.9 to 2.2 percent of the population.

Teeth eruption delays can be caused by a variety of unusual and typical factors. There are several probable reasons, including the presence of radiation and febrile infections, as well as hormonal disturbances. Inadequate dental arch space leads to prolonged retention or the early elimination of primary canine aberrant tooth bud placements. Localized explanations include alveolar clefts, cysts, ankylosis or malignant root dilacerations, a lack of maxillary lateral teeth, or changes in the form and timing of maxillary lateral incisor roots. In many situations, it is assumed that there is an inherited tendency or that the reason is idiopathic. The majority of dog attacks are caused by localized reasons.

If not addressed, canine impacts may cause neighboring teeth to erupt lingually, labially, or lingually, as well as loss of arch length and internal or external root recoil, the formation of dentigerous cysts, and the likelihood of pain or infection. Aside from the risk of difficulties connected with orthodontic treatment or installation, the impacted teeth are normally unaffected.

What is the cause of canine impaction?

Although the majority of the canine teeth grow naturally in the tooth arch these vital teeth may be affected due to various reasons.

The baby teeth are not fully fallen out, or there are abnormal growths that block the canine’s teeth
Excessive dental crowding

The American Association of Orthodontists recommends that children see a dentist by the age of seven for an examination and imaging to check for permanent teeth eruption and canine development. If you are diagnosed with an impacted tooth in your canine, you will be directed to an expert oral surgeon for treatment. Therapy should begin as soon as possible since treatment is less likely to work if a canine tooth is impacted throughout adulthood. If it is not possible to repair a damaged canine implant, dental implants or alternative tooth replacement procedures can be used to replace canines and deliver outstanding cosmetic and functional results.

What does “impacted” mean?

This might indicate that fibrous tissue, bone, or a separate tooth has obstructed their natural emergence. Because the upper canine teeth are the last to erupt, they are more prone to get impacted and fail to erupt in the right position in your upper jaw.

What happens If the condition isn’t addressed?

If the canine stays in the afflicted area, a cystic lesion may form around the tooth’s crown. The cystic lesion might develop infected and damage the roots of neighboring teeth.

The treatment of an afflicted canine is often included in an orthodontic treatment program; it is suggested that you visit with an orthodontic professional to discuss your specific case.

Solutions to Treat

The following are the treatment options for people afflicted with impacted canines:

There will be no intervention; however, patients will be evaluated on a regular basis to look for changes in their pathology.

After surgery, orthodontics can be employed to reposition the previously impacted tooth to the occlusion plane.

Following auto-transplantation, orthodontics, and prosthetic replacement, no more treatment is required.

Unless the tooth is dilacerated, ankylosed, or exhibiting signs of resorption, the impaction is severe and a cyst has been detected, or the patient is hesitant to undertake orthodontic therapy, extraction is usually not indicated. If the problematic canines fall out without any prosthetic or orthodontic treatment, there is a considerable risk of developing dentoalveolar cosmetic concerns, such as surrounding drifting or midline deviation, which can create aesthetic problems and occlusal discordances.

Examining Prior to Canine Exposure Surgery

Before deciding on a surgical therapy, the following diagnostic processes must be completed:

Radiographic and clinical assessment of the afflicted tooth’s vertical, horizontal, and mesiodistal locations. Cone-beam CT might offer vital information about the specific position of the damaged tooth as well as its closeness to surrounding teeth in the case of severe impacts. It is useful for determining the size of the keratinized gingiva.

What would the procedure be Canine Exposure Surgery take?

It is governed by the canine’s posture and whether the procedure is conducted with a local anesthetic or with the assistance of additional intravenous medicine.

A normal local anesthetic visit lasts 60 minutes. Intravenous sedation is usually included in a 90-minute visit. The extra period allows for critical healing time before release.

A surgical procedure that exposes canines that have palatally impaired palates

If an impacted tooth has a tolerable axial inclination and does not necessitate an uprighting operation, surgical exposure can be considered to allow for an emergency that happens spontaneously. Orthodontics may be used to align the tooth after allowing it to grow normally until it reaches the level of neighboring teeth.

Local anesthetic infiltration might be utilized to numb the face or palate at first. To obtain access to the bone, a flap is created or a part of the palate tissue is excised (using the 15, 15C, or 15C scalpel blade, or punching the tissue). To remove the bone, manual or rotary tools such as chisels are used. The bone that surrounds a problematic tooth’s crown can be removed. The bone around the root is preserved to prevent future attachment loss. When the mucosa of the palate that covers the problematic tooth has been fully removed prior to permitting the eruption to be unsupported, a periodontal dressing should be used for 3-8 weeks to prevent the formation of soft tissue around the previously exposed tooth. The dressing may need to be replaced since it gets loose and is regularly torn out during mastication.

If vigorous eruptions of afflicted teeth are required, the canine crown, as in non-aided eruption, is exposed. Then, either during surgery or after recovery, an orthodontic attachment, such as a bonded bracket, can be attached to the tooth (2-6 weeks after surgery). Bracket installation during surgery is typically not advised because to limited access to the impacted tooth’s face. After the canine’s crown has fully matured, the condition can be corrected. After the bracket has been fastened to the tooth, there is no need for a periodontal dressing.

Method of surgical exposure for canines that have dysplasia labial

Only when orthodontic motions have established enough room may labially affect canines be removed. As a result, the afflicted canine should be inserted into the arch of the tooth. If sufficient room cannot be created, the injured canine or the surrounding first bicuspid may need to be removed, depending on the technique utilized.

There are three approaches for exposing the labially affected dog.

The first phase is to expose the flaps that migrate apically, followed by the closed eruption, and finally window development.

Before making a big horizontal incision (approximately 12 millimeters wide) into the mid-crystal region of the ridge coronal to the afflicted tooth, a local anesthetic can be administered to minimize discomfort (with the 15C or 12 scalpel blade). Two incisions are made along the same lines as the horizontal one to release the teeth, and they extend apically into the vestibular mucosa (with identical blade). Elevators for the periosteal are used to lift a split-thickness flap with a scalpel blade. If the bone is present, the bone covering the top of the canines is removed. To safeguard the tooth’s enamel-affected canine, employ caution while using manual or rotary tools such as chisels. When the flap is appropriately adjusted and sutured into position, the keratinized component of the flap will cover approximately 2mm of exposed tooth enamel as well as the CEJ (cementoenamel connection). Sutures are used to hold the flap in place. They are either resorbable at 5-0 or 6-0 or non-resorbable at these concentrations (if the sutures are non-resorbable they should be removed within 1-2 weeks after the operation). A bracket can be pasted overexposed enamel and passively fastened to the archwire using a ligature wire, chain, etc. They are triggered one week after the treatment.

When the afflicted tooth is located beyond the labial cortex and a suitable apical position of soft tissues after surgery is not possible, the closed eruption approach is used. The mucoperiosteal flap is lifted just enough to reveal the bone that protects the tooth’s crown in this method. canine afflicted The bone is exposed enough (as previously stated) to allow for the placement of a bonded bracket, which is kept in place by an archwire through a ligature cable or chain. The flap is then sutured to the archwire once it has been fixed. It is then triggered following a postoperative appointment. The ultimate procedure of soft tissue recontouring is postponed until orthodontic therapy is done.

The third way for revealing labially-impacted canines is to open a hole in the mucosa and then fill it with bone. A scalpel, as well as a 15C or 15C knife, are used to locate the problematic tooth and to remove a portion of the labial mucosa about the size of the canine’s crown. If the bone underlying is present, it is removed as described above, and an attachment bracket is put on the exposed tooth. Due to the lack of keratinized and free and connected gingiva within the canine, the technique is rarely utilized. This increases the pups’ susceptibility to infection and, finally, loss of connection. When the gingiva is fully keratinized, the tooth can be exposed in this manner, and a free tissue transplant is inserted once the canine is appropriately situated within the arch of the tooth.

After-Operation care for Dogs Exposed to Surgery

The patient is instructed to refrain from biting on the operative region for two weeks following surgery. They are also told to rinse for 2 minutes twice a day with 0.12 percent chlorhexidine until the site is comfortable and routine hygiene practices may be resumed.

Will Canine Exposure Surgery cause any pain for me?

Because the local anesthetic has a numbing effect, there should be no discomfort immediately following the treatment.

When the numbness goes away, the region might be painful. At this stage, the pain medication should be used. We’ll mail them to you along with dosing instructions.

When do I get back to work following Canine Exposure Surgery?

It is influenced by your job and the amount to which you recover from therapy. It’s conceivable that you’ll be able to return to work the next day. Certain patients may require time off, especially if the therapy was performed under IV anesthesia. We’ll provide you with advice tailored to your individual need.
