Restoring Function and Stability
Losing all of the teeth in the upper or lower jaw can make eating, speaking, and everyday activities more difficult. While many patients adapt well to an upper denture, lower dentures can sometimes be less stable because of the shape and movement of the lower jaw.
Fortunately, several implant-supported treatment options are available for patients who are missing all of their teeth. The right solution depends on your jawbone condition, oral health, personal preferences, and desired level of stability.
Missing All Lower Teeth
Ball Attachment Denture
One option is to place two dental implants in the lower jaw and create a removable denture that securely snaps onto the implants. This can provide considerably more stability than a conventional lower denture, particularly while eating. The denture can still move to some degree, and food particles may occasionally become trapped underneath it. Because the denture remains removable, periodic adjustments and professional maintenance may be necessary.
Bar Attachment Denture
Another option uses approximately four to six implants, depending on the patient's jaw anatomy and available bone. Once the implants have healed, they are connected with a custom-designed support bar. The removable denture contains specialized attachments that connect to the bar and provide greater stability. This type of restoration, commonly called an overdenture, offers less movement than a denture supported by two implants while still allowing the patient to remove it for cleaning.
Screw-Retained Denture
A more fixed approach involves placing multiple implants and attaching a full-arch restoration directly to the implant-supported framework using screws or other secure attachments. Because the restoration remains fixed in place, it is not normally removed by the patient and is only removed by the dental professional when maintenance is required. The design can also provide access for cleaning underneath the restoration. This option can be appealing to patients who prefer the feel and stability of a fixed full-arch replacement.
Individual Implants
For patients seeking a result that most closely resembles individual natural teeth, each missing tooth can potentially be replaced with an implant-supported crown. This approach generally requires a greater number of implants and individual restorations, making it more complex and costly than other options. The number of implants that can be placed depends on the amount and shape of available jawbone as well as the patient's overall treatment needs. Additional procedures, such as bone grafting, may sometimes be necessary when there is insufficient bone to support the implants.
Missing All Upper Teeth
Patients who have lost all of their upper teeth can also choose from several implant-supported treatment options. The upper jawbone is generally less dense than the lower jaw, so treatment may require careful planning and, in some cases, additional implants. Depending on the number and position of implants, an implant-supported upper denture may be designed without completely covering the roof of the mouth. This can provide a more natural-feeling restoration and may allow patients to experience food texture and temperature more comfortably.
Implant-Retained Upper Denture
An implant-retained upper denture uses dental implants to provide additional support and stability for a removable full-arch denture. Depending on the treatment design and number of implants, the denture may require less coverage of the palate than a traditional complete denture. The restoration remains removable, making it easier for patients to clean both the denture and the supporting implant components.
Individual Upper Implants
Patients who want a fixed restoration that closely resembles individual natural teeth may be candidates for multiple individual implants. This approach can require approximately eight to ten implants, depending on the patient's anatomy and treatment plan. After the implants have healed, abutments and individual replacement crowns can be placed to complete the restoration. Because this option involves more implants and individually fabricated teeth, it is generally a more extensive treatment than an implant-retained denture. The most appropriate option will depend on your bone structure, oral health, functional needs, aesthetic goals, and personal preferences. A comprehensive examination and dental imaging can help determine which approach is best suited to your situation.
