Summary
A mini-implant was used to extrude a short abutment tooth for a fixed partial denture. This approach conserved healthy teeth by reducing the need for additional bonding.
Area of Science:
- Dentistry
- Prosthodontics
- Orthodontics
Background:
- Fixed partial dentures require adequate abutment tooth structure.
- Short abutment teeth can complicate prosthetic treatment planning.
- Tooth extrusion is an alternative to surgical crown lengthening or orthodontic movement.
Observation:
- A case report details the use of a mini-implant for abutment extrusion.
- The mini-implant facilitated the controlled eruption of a shortened abutment tooth.
- This was performed in preparation for a four-unit anterior fixed partial denture.
Findings:
- The mini-implant successfully extruded the abutment tooth to a suitable height.
- This technique allowed for fewer teeth to be incorporated into the fixed partial denture.
- Preservation of adjacent healthy teeth was achieved.
Implications:
- Mini-implant-assisted extrusion offers a minimally invasive option for managing short abutments.
- This method can enhance treatment predictability and preserve tooth structure.
- It presents a viable alternative in prosthetic and restorative dentistry.
