Recent Implants placed in our Office

Bone Level implant

This was done with a zirconia abutment, which is white so there will be no “metal showing” even if the gum receeds. Which will probably not happen because this was such a thick gingival biotype.

Bridge Replacement


Bridge was sectioned, the patient healed for 6 months and after about a year has come back desiring teeth in that area. I explained that we could do implants. Below are the placed implants and the CT scan workup for this site.

Patient had a front tooth that jetted out and didn’t want to re-trude it with an appliance.

We placed an immediate implant. This is where we can take out the tooth atraumatically and place the implant in the extraction site. We then place a bone graft and a collagen membrane and suture the flap closed.

Lower Left Implant Placed where patient was missing a tooth.

A CT Scan should always be taken prior to implants to give the surgeon forsight in to the vital structures such as nerves and blood vessels.

Tissue Level Straumann SLA implant 4.8mm diameter was placed in the area of #18.

Cone Beam Computerized Tomography

What is Cone Beam Computerized Tomography (CT)

Similar to a hospital CT scan, a cone beam CT takes a 3 Dimensional image of bones and hard skeletal structures such as teeth.  Essentially its a 3D X-ray.

This is a relevant and important topic for implant dentistry today. When a patient desires a dental implant, there are important considerations in the planning of where the surgeon will place that implant in solid bone.

A 3D X-ray such as a Cone Beam CT will allow for the surgeon to visualize in 3 Dimensional space where they can exactly place the implant. This is extremely important because it allows them to avoid vital structures such as nerves and blood vessels. Also, it helps them to plan for possible grafting necessary when the bone is insufficient to place an implant.

The Cone Beam CT is an excellent diagnostic tool which will enable your surgeon to avoid any complications or pitfalls in your surgery, before he goes into surgery.

The American Dental Associate and California Dental Associate both recommend a Cone Beam CT be taken before any dental implant is placed.

Is an implant a good option for me?

021_Image_0002In order for an implant to actually fit in a gap between two teeth and into the bone at that site, there is a required width and length for the implant.

059_Image_0003The length of the implant selected must be no longer than 2.0 mm from the inferior alveolar nerve.

It is critical that these vital structures are avoided in placing your implant so you can avoid complications and ensure the  success of the implant integrating into the bone.
