Clinical Application of Magnetic Attachment for Retention and Connection of Maxillofacial Prostheses to an Intraoral Prosthesis

Abstract

This clinical report describes the treatment of a patient who has maxillary and facial skin defects. Dental magnetic attachment was applied as a retentive structure and connector between a removable partial denture and an obtulator, and an obtulator and a facial prosthese. AbstractPatient: A 73-year-old male patient was introduced by his plastic surgeon to the Kyushu Dental College Hospital. Numerous surgical excisions resulted in a defect in the region of the right upper palate. He also had a skin defect on the right cheek due. Although he had worn a removable partial denture and a facial prosthese, he had been complaining of mastication, articulation, and esthetic problems. Seven inner crowns with keeper of magnetic attachment were fixed to the abutment teeth. Metal welding was done between the outer crowns and metal frame. Magnetic assemblies were fixed into the outer crowns. Four magnetic attachments were applied to connect the partial denture and the obtulator. Two magnetic attachments were also applied to connect the facial prosthese and the obtulator.Discussion: Although the new maxillofacial prosthese was heavier than the old one, the VAS score of the patient's satisfaction was 100. An articulation, masticatory function, and mealtime were improved. Conclusion:This clinical report describes the fabrication method for a maxillofacial prosthese by applying dental magnetic attachments for retention and connection. The evaluation of mastication and articulation was done before and after wearing the new prosthese and his complaining improved.

Effectiveness of denture space recording method in the prosthetic treatment of edentulous patients

“…Future studies are needed to elucidate the effectiveness of denture space recording methods in the prosthetic treatment of edentulous patients. [44] Related to maxillofacial defects maxillary defects Masumi [45], Wee [46], Makihara [47] mandibulectomy Masumi [48], Pekkan [49], Patil [50], Halim [51] glossectomy Ichikawa [52], Ohkubo [53], Awuti [54]…”

“…There have been many studies on the application of denture space recording methods. The majority of these reported that they are highly effective in providing denture stability [35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54]. The clinical applications of denture space recording methods were classified into those related to unstable complete dentures [35][36][37][38][39][40], neuromuscular problems [41][42][43][44], and maxillofacial defects [45][46][47][48][49][50][51][52][53][54] (Table 1).…”

“…From several articles on clinical applications, the denture space recording method can be considered a highly effective method for fabricating dentures for edentulous patients with severe ridge resorption [35][36][37][38]. The relationship between the labiolingual and buccolingual pressure differs in patients with neuromuscular problems [41][42][43][44] or with mandibular or lingual defects [45][46][47][48][49][50][51][52][53][54], so a stable prosthesis can be easily fabricated by locating the neutral zone using denture space recording method.…”
