- The use of an incisal rest is more applicable in the mandibular arch.
Disadvantages of Incisal Rests
- Disadvantages of the incisal rest include potential damage to the supporting tooth.
- Another disadvantage is the possible over-contouring of the prosthesis.
Implants as Rests
- An implant can function as a rest to provide additional support and stability to a prosthesis.
- A benefit of using an implant as a rest is that it reduces the load on natural teeth.
- The primary function of an implant as a rest is to provide additional support to the prosthesis.
Ideal Incisal Rest Seat
