Sometimes, as an introductory step before mouth restoration techniques such as insertion of a dental implant, plastic surgery is needed on the jawbone, to refurbish and strengthen the bone. The need for this intervention arises from the fact that after tooth loss, the jaw suffers bone tissue absorption and deterioration. There is a reduction in the height, width and volume of the alveolar bone in the upper or lower jaw. As a result, the jaw is less able to support the roots of the remaining teeth, and without surgical intervention no implants can be installed either.
There are additional causes for bone loss in the jaw, such as severe gingivitis and proximity of the bone ridge to the sinus.
A wide variety of methods for supplementing missing bone volume, but generally the underlying principle is the same — implantation of bone material from other bones of the patient’s body or from “external” organic bone material.
The sinuses are found inside the facial bone cavities near the top of the skull, above the jaw. Where bone grafting in the upper jaw cannot be done because the sinus wall is too close to the designated implant area, a special “sinus-lifting” operation is needed as part of the bone graft.
What is called the “open” sinus-lift method facilitates the raising of the sinus lining five or six millimeters, but sometimes even more. This technique involves an external, lateral opening of the soft facial tissues in the area between the cheek and the gums. Having cut the opening, the doctor gently lifts up the sinus wall. He then takes bone material and uses it to fill in the newly-created space. Afterwards he installs a buffer that prevents contact between the bone material and the gum tissue. The “open” sinus-lift is the classical method, and until recently, only after a five or six-month recovery period could a dental implant be affixed to the jaw. Today there are techniques that allow the implant to be installed during the sinus-lift, which saves a long wait and further cutting of the gums.
“Closed” sinus-lift slightly differs from the “open” method. The incision is made at the future implant site, and less area is cut. Other than that, the principle is similar. The closed method, which is less invasive, is chosen when less lifting is required.
Both methods are involved and delicate, each requiring much skill and professionalism. In our clinic all surgical interventions are performed by a specialist in oral and maxillofacial surgery. He is an expert in this area. His clinical knowledge is extensive and he has many years of experience.
We offer a variety of additional solutions for bone issues, all with the aim of simplifying the procedure, lowering the risk of complications and avoiding a long recovery period.

- Root Canals
What is root canal treatment and when do we need it?
The root is the lower part of the tooth. It goes down to the jawbone and is concealed inside of the gums. Inside the root are root “canals,” located beneath both the root’s enamel coating and the dentin layer under it. Inside the root canals is a pulp – which essentially is the tooth’s nerve center, for the pulp is comprised of blood vessels and nerves.
The dentist decides upon root canal treatment mainly in the following cases:
- There is an infection and inflammation of the pulp and the infection cannot be cured by external medication. Usually, the person suffers strong, sharp pain from this type of inflammation.
- In situations where the pulp is decayed or rotten, to the point where the nerves and blood vessels in the root canal no longer are functioning. This can develop from the tooth having suffered external damage, if afterwards infection of the pulp sets in.
- There is much damage to the tooth’s structure, and considerable decay is apparent. Nevertheless, enough of the tooth remains to support a crown.
What exactly does root canal treatment entail?
Essentially, the root canals are cleaned out by removing the infected pulp and then chemically disinfecting the canals. Afterwards the canals filled in with a sealant. In cases where the cleansing is not complete so infection is still present and spreading, a repeat root canal treatment is needed, which is usually more complex than the previous one.
Usually, root canal treatment requires local anesthesia so during the procedure there is no pain or discomfort. Even after the procedure is completed, during the recovery period, most patients do not feel any pain.
Owing to the fact that the treatment requires precision and delicacy – because it is not uncommon that the root canals are only a few microns wide – the dentist must be highly skilled and experienced.
In our clinic, root canal treatments are performed by Dr. Yaki Mizrahi , an oral medicine specialist and expert, who completed his training at Hadassah Ein Kerem Hospital. His was extensive training, providing him with knowledge and experience regarding a wide variety of diseases and problems of the oral cavity, such as lesions of the mucous membranes of the mouth and lips, functional disorders of the salivary glands and the chewing process, as well as all of the causes of facial pain and jaw pain. As a certified an oral medicine specialist, he is authorized to perform dental procedures for high-risk patients as well, such as those who have diabetes or heart problems, or they recently underwent chemotherapy or radiation treatment.
