The loss of a tooth can sometimes be an emotional event. The loss of even one tooth can drastically change the way the mouth functions. Each tooth in the mouth has a specific and important function. The incisor and canine teeth are in the front part of the mouth. These teeth function to grasp and tear food such as when one bites into a piece of fruit. These teeth obviously are important in ones smile. The premolar and molar teeth are in the back part of the mouth and function to grind food into pieces that are small enough to swallow.
Dental implants may be used to replace teeth anywhere in the mouth. In most cases the process of surgically placing and restoring dental implants is routine and straightforward. In some cases minor or major bone or gum tissue grafting may be necessary. Dr. Ferdowsmakan will discuss the need for bone or tissue grafting at the time of your initial consultation.
The success rate for dental implants is typically greater than 95%. In rare cases dental implants may fail for a variety of reasons. If this occurs Dr. Ferdowsmakan will remove the implant and allow healing prior to the placement of another implant.
Bone grafting is typically performed when there is inadequate bone in the jaw for dental implant placement. Not every patient will need bone grafting. In fact the majority of patients will not need bone grafting prior to dental implant placement. The jaw bone naturally resorbs or “shrinks” to some extent after the loss of one or more teeth. Typically this occurs after several years but in some cases can occur much sooner after the loss of a tooth. Sometimes infection or traumatic injuries can result in significant bone resorption. Fortunately most defects in the jaw bone can be reconstructed with minor or major bone grafting techniques. These grafting procedures can be performed in our office surgical suite.
Minor Bone Grafting
Minor bone grafting is typically performed to reconstruct small defects in the jaw bone prior to dental implant placement. In some cases minor bone grafting is performed at the time of dental extraction to prevent future bone resorption. This makes subsequent dental implant placement much more predictable. Most minor bone grafting procedures are performed using synthetic or bovine bone. This prevents the need for harvesting the patient’s own bone resulting in less discomfort to the patient.
Major Bone Grafting
Major bone grafting is required when there are large defects in the jaw bone usually due to traumatic injuries, removal of cysts or tumors and in some cases after teeth have been missing for many years. In some cases the maxillary sinus floor may need grafting after the removal of molar teeth. Major bone grafts utilize natural bone harvested from the patient. Usual sources of bone include the mandible (lower jaw), iliac crest (hip bone), tibia (lower leg bone) and sometimes the cranium (skull bone). Dr. Ferdowsmakan will discuss the benefits and indications of the different major bone grafting sources and techniques at your consultation appointment.
Sinus Floor Augmentation
Sinus floor augmentation sometimes referred to as “sinus lift” is a predictable method of increasing bone volume in the maxilla (upper jaw) for the placement of dental implants. The maxillary sinus is a normal air-filled cavity in the upper jaw that sometimes expands after the removal of molar teeth. This expansion decreases the amount of bone available for dental implant placement. If this occurs a sinus floor augmentation procedure is performed. During the procedure the thin membrane of the maxillary sinus is gently elevated and bone graft material is placed under this membrane. Depending on the amount of existing bone in the upper jaw dental implants can sometimes be placed concomitantly with the grafting procedure. The bone graft usually requires several months for maturation and eventually will become a part of your own jaw.
Onlay or veneer grafting is employed when the jaw bone is inadequate in width to accommodate dental implants. Bone is typically harvested from either the lower jaw or hip bone and secured to any part of the jaw which requires grafting to increase the width. Once the bone graft has incorporated into the jaw, dental implants may be placed. This usually takes about four to six months to occur.
Wisdom teeth or third molars are the last teeth to develop and to erupt into the mouth. When erupted and properly functioning there usually is no need to remove these teeth. Often there is inadequate space in the jaw for the proper eruption of these teeth. This results in impaction which means the teeth have been unable to erupt into a proper position. When this happens the impacted wisdom teeth can cause problems with the other healthy teeth in the mouth. Impacted wisdom teeth can result in gum disease and eventual bone loss with the molar teeth adjacent to them. This can result in eventual loss of these healthy functioning molar teeth. Impacted wisdom teeth can sometimes result in cavity formation in the adjacent molar teeth necessitating extensive repair of these teeth including the need for root canal treatment and the placement of a porcelain crown. Partially impacted wisdom teeth allow food and bacteria to become lodged in the gap between the tooth and gum tissue often resulting in a painful infection called pericoronitis. In some cases cysts and tumors can develop around impacted wisdom teeth resulting in the need for more extensive surgery to treat these pathologic conditions.
Surgery typically is performed under general anesthesia; however, some patients elect to undergo the procedure with the use of nitrous oxide sedation also known as “laughing gas”. Nitrous oxide sedation usually works well for the mildly anxious patient who desires not to be under general anesthesia.
The procedure is performed in our state of the art surgical suite. Patients are monitored during and after the procedure. Once the surgery is completed patients are monitored in our recovery area where family members can join them until they are ready to be escorted home. A prescription for pain medications can be phoned to the pharmacy if desired; otherwise a written prescription is given which can be taken to any pharmacy. A follow-up appointment is usually scheduled for one week after surgery so that the extraction sites can be checked for proper healing.
Traumatic facial injuries can occur as a result of sports accidents, motor vehicle accidents, work-related accidents or altercations. The facial structures are some of the most frequently injured parts of the body. Injuries can range from minor dental injuries to facial lacerations to fracture of one or more of the facial bones. Oral and Maxillofacial Surgeons are uniquely qualified to diagnose and treat facial injuries.
Dentoalveolar trauma occurs when there is sufficient force to disrupt not only the tooth and tooth socket but the surrounding jaw bone. This type of injury requires care from an Oral and Maxillofacial Surgeon to stabilize the teeth and bone to allow for proper healing. Failure to seek prompt care can result in improper healing of the bone or improper positioning of the teeth.
Facial and Oral Lacerations
Lacerations of the facial skin, lips and oral tissues is not uncommon in traumatic injuries. Lacerations should be repaired as soon as possible after they occur to minimize scarring and to ensure the most cosmetic result. Oral and Maxillofacial Surgeons are well-trained in the cosmetic repair of facial and oral lacerations. Laceration scars can often be lessened with the use of dermabrasion or laser resurfacing after a period of healing.
Facial Bone Fractures
The nasal bones are the most commonly fractured facial bones followed by the cheek bones. This occurs because these bones protrude furthest from the rest of the face. The lower jaw, upper jaw, eye socket and forehead are other areas of the facial skeleton that are sometimes fractured or injured. The proper and timely repair of facial bone injuries is crucial to proper function and optimal esthetics. Late repair of facial injuries can result in poor function and unsightly deformities which may be difficult and sometimes impossible to repair.
Dr. Ferdowsmakan treats all facial injuries. Some injuries can be treated in our office surgical suite at Torrey Hills Oral & Maxillofacial Surgery. More severe or complex injuries usually need to be treated in a hospital setting. Dr. Ferdowsmakan maintains active hospital privileges at Scripps Memorial Hospital, La Jolla, Rady Children’s Hospital and Sharp Memorial Hospital.
