Abstract

A maxillofacial prosthesis (MFP) was inserted to replace the hard and soft tissues and teeth lost after maxillectomy surgery in a case of ameloblastoma. Facial deformity, soft tissue invasion and limited mouth opening caused difficulties in the moulding pro-cess. This article presents anatomical moulding modifications to improve treatment success in MFP placement. A 19-year-old female came to RSGM USU referred from RSU Murni Teguh for immediate post-surgical placement of a maxillary closure device. The patient was diagnosed as ameloblastoma with facial deformity, and tissue invasion on the left side. The patient's facial con-dition was asymmetrical and difficult to open the mouth, making impression difficult. Anatomical impression was performed with modification and selection of appropriate stock tray, followed by fabrication of surgical obturator MFP and Class IV Aramany in-terim as prosthetic rehabilitation device. It was concluded that MFP insertion in post-maxillectomy patients with impression dif-ficulties, modification of the stock tray moulding spoon can determine the success of treatment.

Abstract

ABSTRACTBackground: In teeth with short clinical crowns that will be used as a support for metal porcelain fixed dentures, the problem that often occurs is that the dentures easily fall off after being installed. Surface treatment is one of the efforts to increase retention. Advances in laser technology provide advantages in increasing microstructural and wear resistance on the metal surface of the crown that will be used as abutment teeth.Objectives: In addressing the retention problem of short clinical crowns, modification of tooth preparation, casting, and proper cementation procedures need to be considered. Improving the mechanical properties by surface treatment of the dental crown to be cemented by modifying the strength and focus of the laser diameter can play a role in surface roughness and shear bond strength.Conclusion: The use of lasers to increase microstructural and wear resistance in teeth with short clinical crowns can minimize the failure of making metal porcelain fixed dentures. Keywords: fixed denture, short clinical crown, surface roughness, shear bond strength, laser
