CHAPTER FOUR: THE BUDDY SYSTEM OF RESTORATION FOR MOSTDIS



CHAPTER FOUR: THE BUDDY SYSTEM OF RESTORATION FOR MOSTDIS


COMPONENTS OF THE BUDDY SYSTEM OF IMPLANT DENTISTRY


MOSTDIBUD
BUD: Bridge Underpinning Device

The bud is basically a coping with an O- RING incorporated inside to give a positive repeatable precision placement onto the SDI. It is quite similar to the dental anchoring device (DAD) used with small dental implants. It consists of a housing with an O-Ring incorporated inside.

The BUD is shaped more like a tooth abutment. Larger than the DAD(Denture Anchoring Device), it is about 5mm in height. The MOSTDI is screwed down until only about 4 to 4.5mm is sticking out above the gum level. This results in a smooth metal interface with the mucosa immediately around the SDI. The bud can be cemented and trimmed to size or left as it is, if trimming is unnecessary. The impression is then taken and sent to the lab for crown and bridge construction.

If the bud is not cemented, it can be used to carry a temporary crown or bridge. This can be removed easily when a more permanent restoration is constructed. If a temporary cement is used to cement the BUD onto the abutment, the crown and bridge can be retrieved with a crown remover. Such a BUD can also be used as a DAD with the added advantage that if none of the SDIs are exposed, cold curing of the denture will not go into any undercuts. As such, after cold curing, the denture can be removed with a steady and sustained pull force on the denture. However, if any part of the SDI is exposed, it can be protected with one or more O-rings. The orthodontic elastic separators (O-rings) can be used.
