OCO Biomedical SDI Case

SDI “4-On-The-Floor” Case

Pre-Op Panograph

Dr. Paresh Patel

Patient had a thin ridge. Implants less than 3.0mm were indicated. Notice the facial undercut of the bone

Blue Mousse used to record normal bite before infiltration

Blue bite will be used later to ensure ‘passive fit’ of the denture over the implants and housings

Endo probe used to sound the bone after infiltration

Pilot drill taken to just shy of the implant’s length

Index finger on the lingual side to feel that drill doesn’t perforate the lingual plate

Periodontal probe used to check drilled pilot hole length

Perio probe to 11mm. Probe is also used to feel sound bone on all sides

Thread in implant with the Ultim cap. Angulation was then re-checked visually

Thumb knob and driver engaged to thread implant further

O-Ball head and driving square are finally seated above the tissue which allows the denture to be seated above the tissue.

Use external irrigation (sterile water) while drilling

Second implant seated to depth

The doctor feels the lingual while the assistant feels the facial to ensure no perforations from the pilot drill

The o-ball heads are marked with the Thompson Stick to give a general location of the implant location in the denture. The transfer

marks on the denture indicate where to begin removing acrylic.

Axis Crosscut Medium Grit (pear shaped) is used to relieve the denture

After the general location is marked, it is best to relieve the denture one cap at a time so that you get a good passive fit

The transfer mark indicates that the housing is rubbing the denture – need to remove more acrylic to ensure passive fit

No purple transfer marks. Now we have a passive fit. Denture is ready to reline for chair side pickup of housings

Housings with O-Rings are engaged onto O-balls

Reline material is injected into the relieved areas of denture

The denture is removed. Excess acrylic is removed and any voids are filled in with flowable composite..

Patient was given1,000 mg of Amoxicillin 1 hour before surgery. Peridex rinse was used one hour before surgery and three days post surgery.
