All You Need to Know About Single-Unit Dental Implants
Single-unit dental implants refer to a popular treatment option for tooth loss which is suitable when only one or a few teeth need to be replaced. It refers to a procedure that involves the placement of a single dental implant into the gums and jaw tissue. Unlike multiple-unit implants, which replace multiple teeth simultaneously, single-tooth implants are individual units. While this is so, many patients may require multiple single-unit implants as part of their treatment plan to fix specific teeth in their mouth. Single-tooth dental implants are typically used in less severe cases or with other treatments as part of a more complex tooth replacement procedure.
Types of Single-Unit Implants
According to Dentakay Dental Clinic, among the various types of dental implants available, single-unit dental implants are a popular choice for restoring individual teeth. Here’s an overview of the different types of single-unit dental implants commonly used today.
Endosseous Implants:
Endosseous implants, also known as root-form implants, are the most widely used type of dental implant for single-tooth replacement. They mimic the natural tooth root structure and are typically made of biocompatible materials like titanium or zirconia. Endosseous implants are surgically placed into the jawbone, providing a stable foundation for the prosthetic tooth. Screw-type implants and cylindrical implants are types of endosseous implants
Screw-Type Implants
Screw-type implants feature a threaded design, allowing them to be securely anchored into the bone. The screw-like structure provides excellent primary stability and is suitable for patients with adequate bone density.
Cylindrical Implants:
Cylindrical implants have a straight and smooth body, void of threads. They rely on osseointegration, the process where the implant fuses with the surrounding bone, for stability. Cylindrical implants are often used in cases with limited bone width or when immediate loading is desired.
When are Endosseous Implants Suitable?
Endosseous implants are suitable for patients with sufficient bone density and volume. Screw-type implants provide excellent primary stability and are ideal for cases with good bone support. Cylindrical implants are often used when immediate loading or limited bone width is a concern. Successful placement of endosseous implants requires adequate bone quality and quantity. Preoperative evaluation, including bone density assessment and radiographic imaging, will be essential. Patients with compromised bone density may also require bone grafting or augmentation procedures to ensure implant stability.
Subperiosteal Implants:
Subperiosteal implants are an alternative to endosseous implants when there is insufficient bone volume for their placement. This type of implant is custom-made to fit on or above the jawbone, beneath the gum tissue. They consist of a metal framework with posts that extend through the gums to support the prosthetic tooth.
When are Subperiosteal Implants Suitable?
Subperiosteal implants are used when there is insufficient bone volume for endosseous implants and bone augmentation procedures are not feasible. They are suitable for patients who have experienced bone loss and cannot undergo extensive surgical procedures. However, it is important to consider that subperiosteal implants require precise design and fabrication, often involving advanced imaging techniques like CT scans. They may be more complex to place than endosseous implants and are typically recommended for cases with severe bone resorption. They are also recommended when other implant types are not viable.
Transosteal Implants:
Transosteal implants, also known as mandibular staple implants, are rarely used today due to advancements in implant technology. They involve the insertion of a metal plate or frame through the mandible (lower jawbone) to support the prosthetic tooth. However, transosteal implants are associated with a higher risk of complications and may require extensive surgical procedures. Due to advancements in implant design and techniques, they are less commonly used compared to other implant options.
When are they suitable?
Transosteal implants are reserved for complex cases where other implant types cannot be utilised. They may be considered in situations with limited bone availability or when multiple teeth need replacement.
Blade Implants:
Blade implants have a flat, thin design resembling a blade. They are inserted into the jawbone and rely on their wide surface area for stability. Blade implants are not as common as other implant types and are generally used in specific situations. This includes situations where there is minimal bone height or when multiple tooth replacements are required.
When are they suitable?
Blade implants are typically used in cases where there is minimal bone height or when multiple tooth replacements are required. However, blade implants require careful case selection, as they are less common and not suitable for all patients. They may have certain limitations in terms of bone quality and the ability to achieve optimal stability compared to other implant types.
It’s important to note that the choice of implant type depends on various factors. These include the patient’s oral health, bone condition, and the expertise of the dental professional. A thorough evaluation and consultation with a qualified dentist or oral surgeon will help determine the most appropriate type of single-unit dental implant for each individual case.
Potential Complications Associated with Single unit dental implants
There is a chance that dental implants may encounter certain complications. These include rare occurrences of implant failure due to infection or inadequate adjustment of the bite (the alignment of teeth coming together). Additionally, clenching or grinding of teeth can exert excessive pressure on the implant, potentially leading to bone loss and implant fracture or failure. Insufficient oral hygiene practices and a lack of regular preventive professional care can also contribute to implant failure.
When lower teeth are replaced with implants, there is a risk of injuring a nerve in the jawbone, which can result in temporary or permanent numbness or tingling. At our clinic, however, we utilize X-rays and CT scans to locate the nerve and minimize the likelihood of injury. There is also a slight risk of sinus issues if a dental implant in the upper jaw extends into one of the sinus cavities. Nevertheless, these risks are uncommon.
Although dental implants require time to become healthy and secure, they may not be the simplest procedure. After receiving your new implant and crown, it is crucial to maintain proper care not only for the implant but also for your entire oral cavity.
