Graftless Surgery — Zygomatic Implants & All-on-4

Zygomatic Implants


Fortunately – we have excellent solutions for people that have lost most of their bone in their upper jawbone (maxilla).

We utilize the Zygoma to place implants – 1 to 2 per side to facilitate support for your upper prosthesis.  This can be done in conjunction with traditional implants or 2 zygomatic implants per side.  Sometimes with a more posterior implant (Pterygoid Implant).  This allows us to provide immediate implant supported teeth the day of your surgery.  

Dr. Loetscher is proficient in this advanced technique.  Below are some of his patients.  

One Zygomatic implant per side:

2 zygomatic implants per side (Quad Zygoma)

Graftless All-on-4 Dental Implants

All-on-4 is a dental term referring to putting a whole set of teeth on 4 implants per dental arch.

This technique facilitates easier cleaning, reduced cost, also allowing a new set of teeth to be placed on your implants the same day we remove your failing teeth.

All-on-4 is performed when there is adequate bone to place the four implants. Usually this is the case, when teeth are being extracted, or there is still a fair amount of bone left in an edentulous jawbone (no teeth). By angling the implants up to 30 degrees in a front-back direction, it spreads them out, allowing a more even distribution of bite forces on just 4 implants.

If your upper jaw has extreme atrophy – we can combine an all-on-4 technique with zygomatic implants.  This allows an immediate set of fixed teeth – also avoiding bone grafts. 

Cost reduction occurs because we often can eliminate bone grafting, procedure time, and along with that post-op discomfort.

During your consult, we will determine what is most ideal for your situation — 4,5, or 6 implants per dental arch. The 5th and 6th implants may be recommended to provide a larger arch of teeth, or more stability for your prosthesis if you have significantly large bite forces. 

Typical prosthetic guidelines as determined by engineering analysis usually calls for 4 to 6 implants in the lower arch, and 4-6 implants in the upper arch. With the additional implants (5th and 6th) being placed when needed posteriorly in the molar area where the large bite forces exist. With these traditional reconstructions using 6 lower and 6 upper implants, long-term success after 25 years is high, 98-99% for being trouble free. The usual issue is the teeth wearing out after 20 plus years.
