Can I Get Dental Implants with Only 7mm Bone Height? - Dentistry

When considering dental implants with only 7mm of bone height, there are several important factors to take into account. Your dentist's recommendation to use a short implant of 8.5mm in height is based on the current bone structure and the potential for bone growth. However, the situation is complex, and it is essential to weigh the options carefully.

1. Bone Height and Implant Stability: The ideal bone height for placing a dental implant is generally around 10mm or more. With only 7mm of bone height, there is a risk that the implant may not be adequately anchored, especially if it is expected to protrude 1.5mm beyond the bone. This could lead to complications such as implant failure, infection, or discomfort. The protrusion of the implant into the sinus cavity or other anatomical structures can also pose risks, including sinusitis or damage to surrounding tissues.

2. Bone Grafting Considerations: If your dentist suggests bone grafting, this could be a viable option to increase the bone height before placing a longer implant. Bone grafting involves adding bone material to the area where the implant will be placed, allowing for better stability and integration of the implant. This procedure can be done using your own bone, donor bone, or synthetic materials. While bone grafting may require additional healing time, it can lead to a more stable and long-lasting implant.

3. Long-term Success and Aesthetics: Longer implants tend to provide better stability and are generally associated with higher success rates. They can also help in maintaining the integrity of the surrounding bone and gum tissue, which is crucial for aesthetics and function. If the implant is placed correctly, it can minimize the risk of complications such as bone resorption or gum recession, which can occur with shorter implants.

4. Research and Evidence: The mention of Korean studies suggesting that bone may grow under the implant is interesting, but it is essential to approach such claims with caution. While there is evidence that certain techniques can promote bone growth, the success of these methods can vary significantly based on individual circumstances, including the quality of the existing bone and the overall health of the patient.

5. Consultation with Specialists: Given the complexity of your situation, it may be beneficial to seek a second opinion from a specialist in oral and maxillofacial surgery or a periodontist. They can provide a more comprehensive evaluation of your bone structure and discuss advanced options such as guided bone regeneration or sinus lifts if necessary.

In conclusion, while it is technically possible to place a dental implant with only 7mm of bone height, the long-term success and stability of such an implant are questionable. Bone grafting to increase the height and using a longer implant may provide a more reliable solution. It is crucial to discuss all available options with your dental care provider, considering both the risks and benefits, to make an informed decision that aligns with your health and aesthetic goals.
