Abstract

Patient chief complaint: A female aged 48 years came to the Hasanuddin University Dental Hospital, Makassar. She complains difficulty of chewing and a lack of confidence. Patient status: Full edentulous maxillary and edentulous partial mandible. Diagnosis full edentulous maxillary and class 1 Kennedy mandible. Treatment plan: Fabrication of partial metal frame dentures using the altered case impression technique. Detail of therapy: Panoramic Radiological images appear to be missing all teeth in the maxilla, available teeth: 33,32, 31, 41, 42, and 43, residual the roots of teeth 15 and 28. The pre-prosthetic treatment plan was scaling and extracting the remaining roots on teeth 15 and 28. The first prosthodontic treatment is Preliminary impression was made. Subsequently, the diagnostic model is placed on top of the surveyor for inspection and design of the metal frame. Making individual impression upper and lower jaw using self-curing acrylic material, then doing border molding with greenstick. An additional laboratory procedure for altered cast technique is done by splitting the master cast with a saw. A groove or indentation is made on the cut surface of the mold to help retain the cast to be mixed. The denture metal frame is placed over the grooved mold. The final impression was then beading, and boxing made before it was cast with a cast so that an altered cast was obtained. Making bite rims of the maxilla and mandible and determining the alignment, vertical dimensions, using a bite rim made from the final impression, face-bow transfer, and installation on the articulator. Try the arrangement of teeth. Acrylic processing, selective remounting, and grinding. Denture inserted and controlled, checked for occlusion, articulation, retention, and stability. Clinical significance of therapy: Metal frame partial denture with Alter cast impression technique provides better and stable denture.

Abstract

Patient Chief Complaint: A 41-year-old female, came to the Dental Hospital of UNHAS with a chief complaint of difficulty in eating and lack of confidence. Patient Status: Clinical examination shown a complete edentulous in the upper jaw and partial edentulous in the lower jaw. The remaining teeth were 33, 34 and 43. Treatment Plan: Magnetic Attachments were planned on 33 and 43 and metal coping on 34 as retained for mandibular overdenture. Details of Therapy: Pre prosthetic treatment was carried out by root canal treatment on teeth 33, 34 and 43. Primary impression of the maxillary and mandibular arch was made. Magnetic attachments were planned on 33 and 43 and metal coping on 34. The abutment tooth decapitated about the same as the gingival margin. A bevel around the circumference was made. Surface shape of the root tooth was dome-shaped, and the finishing line is shoulderless. Post space impression was made with polyvinyl siloxane. Metal coping for 34 and cast post with keeper magnet for 33 and 43 was fabricated. The metal coping and cast posts metal containing keeper magnet were carefully cemented using glass ionomer cement. Border moulding was done for maxillary and mandibular arch. Occlusal rims were fabricated on final cast. Vertical dimensions and jaw relation was done then face-bow transfer and mounting the rims on the articulator. Try in, then denture was processed and inserted in patient’s mouth. The magnets are placed under the mandibular denture, which is faced the keeper teeth, then polished and checked for comfort, occlusion, and retention. Clinical Significance: Magnetic attachments significantly increase the retention of mandibular overdenture; patient is more satisfied and comfortable. Patient doesn’t experience difficulties in insert and removing the denture because when the denture is slightly shifted, the magnetic attachment returns it to its original position.
