Abstract

Cases of tooth loss involving several teeth are often not recommended for fixed bridge denture treatment. In such cases, a prosthodontic treatment plan with a precision attachment design becomes very important, especially if it involves anterior teeth. The advantages of a precision attachment design are that it can be made in the denture space or streamlined, is comfortable to use and can significantly improve aesthetic function because it does not require a clasp arm. The type of attachment used in this case is an extra-coronal attachment. The primary consideration is that the mesiodistal space and buccal-lingual distance as the attachment site for teeth 11 and 21 looks narrow, require minimal tooth reduction and facilitate the direction of installation. The selection of the type of extra coronal attachment uses a rigid attachment type, namely an extra coronal rod attachment. This choice is based on the results of vertical space measurements showing less than 2.8 mm and can still use the total number of abutment teeth. Efforts to maintain the condition of the abutment teeth by using an extra coronal rod attachment are carried out using acrylic resin dentures and a female cap attachment. This female cap attachment can absorb adverse movements to protect the abutment teeth as shock absorber and functions to control flexibility. Prosthodontic treatment with precision attachment design, with its significant aesthetic improvement, can provide a sense of appreciation for the enhanced appearance.
