New Approach to 3D Printing of Facial Prostheses Using Combination of Open Source Software and Conventional Techniques: A Case Report

The wax sculpting of a maxillofacial prosthesis is challenging, time-consuming, and requires great skill. Rapid prototyping (RP) systems allow these hurdles to be overcome by enabling the creation of a customized 3D model of the desired prosthesis. Geomagic and Mimics are the most suitable software programs with which to design such prostheses. However, due to the high cost of these applications and the special training required to operate them, they are not widely used. Additionally, ill-fitting margins and other discrepancies in the final finished products of RP systems are also inevitable. Therefore, this process makes further treatment planning difficult for the maxillofacial prosthodontist. Here, we report the case of a 62-year-old woman who attended our clinic. Initially, she had presented with a right facial defect. This was later diagnosed as a squamous cell carcinoma and resected. The aim of this report is to describe a new technique for the 3D printing of facial prostheses which involves the combined use of open-source software, an RP system, and conventional methods of fabrication. The 3D design obtained was used to fabricate a maxillofacial prosthesis to restore the defect. The patient was happy with the esthetic outcome. This approach is relatively easy and cheap, does not require a high degree of non-medical training, and is beneficial in terms of clinical outcome.

Design and fabrication of facial prostheses for cancer patient applying computer aided method and manufacturing (CADCAM)

Facial defects are either congenital or caused by trauma or cancer where most of them affect the person appearance. The emotional pressure and low self-esteem are problems commonly related to patient with facial defect. To overcome this problem, silicone prosthesis was designed to cover the defect part. This study describes the techniques in designing and fabrication for facial prosthesis applying computer aided method and manufacturing (CADCAM). The steps of fabricating the facial prosthesis were based on a patient case. The patient was diagnosed for Gorlin Gotz syndrome and came to Hospital Universiti Sains Malaysia (HUSM) for prosthesis. The 3D image of the patient was reconstructed from CT data using MIMICS software. Based on the 3D image, the intercanthal and zygomatic measurements of the patient were compared with available data in the database to find the suitable nose shape. The normal nose shape for the patient was retrieved from the nasal digital library. Mirror imaging technique was used to mir...

Combined Mandibular Guidance Therapy in the Management of a Hemimandibulectomy Patient

This case history report describes two different devices, maxillary ramp prostheses (MRP) and mandibular guide flange prostheses (MGFP), prescribed for managing a hemimandibulectomy patients deviated mandible. The patient was given muscle reprogramming exercises with coordinated use of both guidance prostheses for 2 months, leading to improvements in both postsurgical mandibular deviation and occlusal equilibration. A successful intercuspal position was eventually accomplished through the use of the combination therapy. MRP and MGFP can be a useful approach to avoid mandibular deviation and compromised function following a partial mandibular resection.

Use of anatomical undercut in adhesive retained orbital prosthesis: an alternative to osseointegration to improve retention and reduce margin gap.

Introduction: Poor retention, stability and margin gap due to excessive bone lose following surgery is one of the major problems of rehabilitation in orbital defect with adhesive retained orbital prosthesis. Presentation of Case: This clinical report describes a simplified technique for the fabrication of an adhesive retained silicone orbital prosthesis by proper evaluation and using of remaining tissue undercuts to achieve ideal fit and aesthetics in a patient who has severely loss orbital bone after Case Study Wadud et al.; BJMMR, 6(8): 841-847, 2015; Article no.BJMMR.2015.258 842 the surgery. Discussion: Aesthetics will be compromised if the proper evaluation of remaining tissue and treatment plan is not done prior prosthetic rehabilitation. To solve this issue sometimes maxillofacial prosthodontist may have to think for implant retained facial prosthesis. This is also sometime not possible due to several factors such as peri-implantitis, hygiene practice and dose of radiation etc. Conclusion: Proper use of remaining anatomical undercuts can be an alternative way to

Orthodontic treatment combination with auto transplantation for the management of impacted maxillary left lateral incisor and canine: an interdisciplinary approach.

Aims: For the orthodontic treatment of the complex cases, the interdisciplinary team work is of utmost importance, which leads to the predictable outcome with excellent treatment. The prime aim of this rare case report is to demonstrate the combined orthodontic-surgical-endodonticprosthodontic interdisciplinary management. Case Study Alam et al.; BJMMR, 4(3): 276-284, 2015; Article no.BJMMR.2015.449 277 Presentation of Case: This report describes the case of a 19 years old Malay male patient with the clinical problems of median diastema, mesio-buccally rotated maxillary left 1 st premolar, mild mandibular incisor crowding along with impacted maxillary left lateral incisor and canine. Discussion: With the advantages of the orthodontic fixed appliance, auto-transplantation of maxillary upper left lateral incisor and canine, the case was completed in an ideal orthodontic occlusion along with improved oral condition, masticatory function and esthetics. The treatment outcomes were due to orthodontic-surgical-endodontic-prosthodontic treatment with stable occlusion in sequels visits. Conclusion: An Interdisciplinary management achieved successful functional and esthetic results in the present case.
