Dental Implants

Dental Implants

At Siouxland Oral & Maxillofacial Surgery, we offer several types of dental implants in addition to traditional dental implants. We will determine the right choice for you during your first visit. There are two general categories of dental implants

Endosteal Implants

This type of dental implants placed in bone, and require osseoinegration prior to complete loading and fabrication of prosthetic components. There are several subtypes which will be discussed below including: titanium endosteal implants (traditional), zygomatic implants and zirconia implants

Endosteal implants

Subperiosteal Implants

Subperiosteal implants are used when there is insufficient bone for traditional endosteal implants to be possible and when grafting is not feasible. Usually reserved for severely resorbed mandibles (atrophic) or patient’s who require reconstruction after surgical resections

Endosteal Dental Implants

Endosteal dental implants are fused to the bone in the process known as osseointegration, whereby a dental implant is placed within the boned and slowly the patient’s bone heals to the surface of the implant circumferentially, thereby obtaining its stability and strength.  Osseointegration was first applied in the dental context by a Swedish physician and scientist, Per-Ingvar Brånemark in the 1960s. Vast majority of dental implants utilized in United States are a titanium alloy, which is biocompatible and safe.

Zygomatic Implants

Patients who lack sufficient upper jaw bone may not qualify for traditional dental implants. In these cases, zygomatic implants, or zygoma implants, are an excellent option. Zygomatic implants are inserted into the cheek bone, or zygomatic bone, instead of the upper jaw. There is typically no need for bone grafting when placing a zygomatic implant, making the treatment process much faster while providing the same results as traditional implants. If you have bone loss in the upper jaw, we invite you to contact our practice to see how our oral surgeons can restore your teeth with long-lasting zygomatic implants.

Ceramic (Zirconia) Implants

Zirconia implants are a metal-free alternative to traditional dental implants and provide the same restorative and health benefits. Zirconia is a ceramic material that closely resembles the natural color of teeth to create aesthetically pleasing results. Zirconia is durable and provides the same functionality as a titanium, so your ceramic implant will still feel and function naturally. Because zirconia implants are metal-free, they are a holistic option and ideal for patients with metal allergies or sensitivities to titanium but have fewer options for crowns and bridges. As such, they demand a higher level of mastery in their placement and restoration. In some cases, it is not possible to use these implants but for the majority of cases they are just as good as traditional implants and typically have a better soft tissue response.

Subperiosteal Implants

Subperiosteal implants (skeletally fixated) rather than being placed in the bone (endosteal), sit on top of a patient’s bone, but under the gum tissue. They are advantageous when a patient has large bony defects or severe atrophy of the maxilla or mandible and grafting is not an option or possible.  Used only infrequently in the last 30 years given the high success of endosteal implants and traditional methods of fabrication required a traditional impression of the bone prior to fabrication of the prosthesis. Therefore it would require two surgeries both requiring extensive soft tissue release and large bony exposure. Subperiosteal implants are making a resurgence in applicability in the last few years now with the integration of high-resolution cone beam CTs imaging with titanium laser deposition additive manufacturing process. Fabrication of patient-specific subperiosteal hardware is now more accurate using the data from CT imaging, and fabrication of the patient specific prosthesis occurs prior to surgery.
