Mini Implants

Implant Dentistry

Mini dental implants—sometimes called narrow- or small-diameter implants—are thinner than many conventional dental implants. They are surgically placed into the jawbone and may be used to help retain a removable denture or for other limited applications, depending on the specific implant system.

Many mini implants have a one-piece design with a small attachment above the gums. A corresponding attachment inside the denture connects to the implant and helps reduce unwanted movement.

How mini implants support a denture

Several mini implants may be positioned across the jaw to retain a removable overdenture. The denture connects to the implant attachments but can still be removed by the patient for daily cleaning.

The number, size, and position of implants depend on your anatomy, bone quality, bite forces, denture design, and the specific system being used.

How they differ from conventional implants

Their smaller diameter may make mini implants useful when space is limited or when a patient has a narrow area of bone. However, less available bone does not automatically make someone a candidate, and mini implants do not eliminate the possible need for grafting or another treatment.

Because mini implants have different mechanical properties and treatment limitations, they may not be appropriate in areas exposed to heavier biting forces. Conventional implants may provide a better foundation in some situations. Neither approach is automatically better—treatment must be selected for the individual patient.

Are you a candidate?

Your evaluation may include:

• An examination of your gums and existing denture
• Dental imaging to assess available bone and nearby structures
• A review of your health history and medications
• Evaluation of your bite and chewing forces
• Discussion of tobacco use, diabetes, gum disease, or other factors that may affect healing
• Assessment of whether your current denture can be adapted or a new denture is required

What treatment involves

Mini implant placement is still a surgical procedure. Local anesthesia or another appropriate comfort option may be used. After placement, your dentist will evaluate the initial stability of each implant.

Some mini-implant systems permit a denture to be connected on the day of placement when appropriate stability and loading conditions are present. Other patients may need a healing period before the implants support the denture. Same-day attachment should not be promised before treatment.

Benefits and limitations

Potential benefits may include:

• Improved denture retention
• Less unwanted denture movement
• Reduced reliance on adhesive
• A smaller implant diameter than conventional options

Possible complications include infection, discomfort, failure to integrate with the bone, implant loosening or fracture, inflammation around the implant, and wear of the denture attachments.

Ongoing care

The denture should be removed and cleaned according to your dentist's instructions. The implants, attachments, gums, tongue, and denture also require daily care.

Professional follow-up is needed to evaluate the tissues around the implants, denture fit, attachment wear, and implant stability. Attachment inserts and denture components may eventually require adjustment, repair, or replacement.
