Dental Implants

Dental implant surgery is a procedure that replaces tooth roots with titanium screws. They are a great option when replacing unrestorable teeth or missing teeth. Dental implants can also offer a welcome alternative to dentures or bridgework that doesn’t fit well.

How dental implant surgery is performed depends on the type of implant and the condition of your jawbone.  Dental implant surgery may involve several procedures.  The major benefit of implants is solid support for your new teeth — a process that requires the bone to heal tightly around the implant. Because this bone healing requires time, the process can take a few months.

Zygoma implants (or zygomatic implants): These are different from conventional dental implants in that they anchor into the zygomatic bone (cheek bone) rather than the maxilla (upper jaw).  They may be used when maxillary bone quality or quantity is inadequate for the placement of regular dental implants.  Inadequate maxillary bone volume may be due to bone resorption as well as to pneumatization of the maxillary sinus or to a combination of both.  The minimal bone height for a standard implant placement in the posterior region of the upper jaw should be about 10 mm to ensure acceptable implant survival.  When there is inadequate bone available, bone grafting procedures and sinus lift procedures may be carried out to increase the volume of bone.  Bone grafting procedures in the jaws have the disadvantage of prolonged treatment time, restriction of denture wear, morbidity of the donor surgical site and graft rejection.

Bone grafting: Patients with significant bone loss may not be immediate candidates for dental implants, but we can perform a bone graft to improve the dental implant foundation.

Sinus lift: Maxillary sinus floor augmentation (also termed sinus lift, sinus graft, sinus augmentation or sinus procedure) is a surgical procedure which aims to increase the amount of bone in the posterior maxilla (upper jaw bone), in the area of the premolar and molar teeth, by lifting the lower Schneiderian membrane (sinus membrane) and placing a bone graft which will ultimately be a much better foundation for dental implants.
