dental abutment การใช้

• Cast definitive palatal lift prosthesis clasps engage dental abutment surfaces harboring what typically represent 0.01 or 0.02 inch undercuts responsible for prosthetic retention.
• If the orthodontic wire clasp terminated at its approximation with the dental abutment undercut it engages as do conventional removable partial denture clasps, the interim palatal lift prosthesis could be difficult to insert and remove.
• Such undercuts can be bilaterally added to the most posterior dental abutments by bonding a bulk of composite resin to the buccal surface of the proposed retainers if they are adult teeth and the surfaces to which the composite resin is to be added are not restored with metallic or ceramic restorative material.
