Types of Dental ImplantsBeaverton, OR When a patient begins researching tooth replacement options, dental implants frequently come up as the most comprehensive and durable solution available. What is less immediately clear is that "dental implants" are not a single, one-size-fits-all approach. The term encompasses a range of implant types, placement techniques, and supported restorations, each suited to different clinical situations. Knowing how these options differ, and why we might recommend one over another at Simonsen Dental, helps our patients participate more actively in their own care.The Foundation: How Dental Implants WorkEvery dental implant system, regardless of type, functions on the same fundamental principle. A titanium or zirconia post is placed in or near the jawbone and allowed to fuse with the surrounding bone through a process called osseointegration. During this healing period, which typically spans several months, the bone grows into and around the implant surface, creating a stable anchor. Once integration is confirmed, a connecting piece called an abutment is attached, and the final restoration, whether a crown, bridge, or full arch of teeth, is secured in place. This root-level support is what distinguishes implants from conventional bridges and dentures. Because the implant stimulates the bone the way a natural root does, it helps preserve jawbone density and prevent the facial changes that often accompany prolonged tooth loss. Endosteal Implants: The Most Common ChoiceEndosteal implants are placed directly within the jawbone and represent the most frequently used implant type in modern dentistry. They come in varying widths and lengths, allowing providers to select a post that fits the patient's available bone. In most cases, adequate bone height and density are necessary for placement, and patients who have experienced bone loss may benefit from a bone graft prior to implant surgery.  After the post is placed and allowed to integrate, a crown, bridge, or implant-supported denture is attached. Endosteal implants are appropriate for replacing a single tooth, several isolated missing teeth, or supporting multi-tooth restorations across a larger span. Their versatility and strong track record make them the preferred option when the bone can support them.Subperiosteal Implants: An Option for Limited BoneSubperiosteal implants take a different approach. Rather than being inserted into the jawbone, they are placed on top of the bone, beneath the gum tissue. A custom metal framework is designed to conform to the shape of the patient's jaw, with supporting posts that protrude through the gum to hold the restoration. This type of implant was more frequently used before bone grafting procedures became widely available and refined. Today, subperiosteal implants are reserved for patients who do not have the bone volume needed for endosteal implants and who are not suitable candidates for grafting. While less common, they remain a valid option for specific cases where other approaches are not possible. Zygomatic Implants: For Severe Upper Jawbone LossPatients who have experienced severe deterioration of the upper jawbone present a unique challenge for implant placement. In these cases, zygomatic implants may provide a solution. Instead of anchoring in the maxillary bone, zygomatic implants extend into the cheekbone, or zygoma, which remains dense even when the surrounding jaw structure has significantly diminished. Zygomatic implants are among the most technically demanding procedures in implant dentistry and are performed by specialists with extensive surgical training. They are not a first-line option but are particularly valuable for patients who have been told they cannot receive implants due to insufficient bone and who wish to avoid, or are not medically suited for, extensive grafting procedures. Mini Implants: Smaller Diameter, Specific ApplicationsMini dental implants are narrower in diameter than standard implants, which allows for placement in sites with limited bone width. They require less invasive surgery and, in some applications, can be placed and loaded with a restoration on the same day. Mini implants are most commonly used to stabilize lower dentures, an application where they provide a significant improvement in function and comfort compared to conventional removable dentures. They are not a universal replacement for full-sized implants, as they are not designed to bear the same occlusal forces. A detailed evaluation will determine whether mini implants are appropriate based on the location of missing teeth, available bone, and the patient's functional needs. Implant-Supported Restorations and What They ReplaceThe type of restoration placed on top of the implant is just as important as the implant itself. Different restorations are designed for different replacement needs.
All-on-4: A Fixed Full-Arch SolutionAll-on-4 is a well-established full-arch implant approach that uses four implants to support a complete set of fixed teeth. Two anterior implants are placed vertically, and two posterior implants are angled to maximize contact with available bone. This angled placement is key because it often allows for implant placement in areas of moderate bone loss without requiring a bone graft first. Patients who are missing all their teeth, or who are facing the loss of remaining teeth, often find All-on-4 to be a compelling alternative to traditional dentures. The fixed restoration does not shift or require adhesives and allows patients to eat, speak, and go about daily life with greater ease. Questions to Ask During Your Implant ConsultationBefore deciding on a type of implant, a thorough consultation with our dental team at Simonsen Dental is essential. A comprehensive examination, including three-dimensional imaging of the jaw, will reveal the condition of the bone and guide the recommendation. It is worth asking about healing timelines, whether bone grafting may be needed, how many implants will be required, and what type of restoration is planned. Our team is experienced in evaluating patients for the full range of implant solutions. To schedule a consultation and find out which option is right for you, call us today at (503) 213-7004. |
