This clinical case report deals with a rehabilitation of a patient with an extensive maxillary and orbital defect using an intra oral prosthesis obturating the maxillary defect and extra oral orbital prosthesis retained with rare-earth magnets for secondary retention; primary retention was derived by snug fit of the prosthesis to underlying and adjacent tissues. The rehabilitation resulted in improved function, esthetics and comfort to the patient thus enabling him to lead a normal life.     

Prosthetic Rehabilitation of an Orbital Defect: A Case Report

Mutilation of a portion of a face can cause a heavy impact on the self image and personality of an individual. Surgical removal of an eye is a severe handicap to a patient because the most important sensory organ of communication is lost. Depending on the severity of the defect Ocular/Orbital prosthesis are required in these patients for rehabilitation. This case report details the clinical management of a patient following enbloc removal of an eye. Fabrication of a sectional two piece orbital prosthesis has been detailed. The importance of meticulous treatment planning to tackle the challenges faced in fabricating an orbital prosthesis is explained with relevant literature.     

Use of Orbital Conformer to Improve Speech in Patients with Confluent Maxillectomy and Orbital Defects

The basic objective in prosthetic restoration of confluent maxillary and orbital defects is to achieve a comfortable, cosmetically acceptable prosthesis that restores speech, deglutition, and mastication. It is a challenging task complicated by the size and shape of the defects. The maxillary obturator prosthesis often satisfies the objective of adequate deglutition; however, orbital defects that are not obturated in the medial, septal, or posterior walls allow air to escape, negatively impacting phonation. This article describes a technique to achieve favorable prosthetic rehabilitation in a patient with a maxillectomy and ipsilateral orbital exenteration. The prosthetic components include maxillary obturator, orbital conformer, and orbital prosthesis connected using rigid magnetic attachments.     

Modified Hygienic Epitec System Abutment for Magnetic Retention of Orbital Prostheses

Maintenance of healthy periimplant soft tissue is a significant problem for orbital prosthesis wearers. Two female patients with orbital defects after malignant tumor resection were treated using custom‐made retentive components of an individual magnet for an Epitec System orbital prosthesis. Freestanding hygienic retentive components for an individual magnet were fabricated. An abutment replica was trimmed and modified, and using pattern resin, a magnetic keeper was cast and soldered to the abutment. The patients could maintain good hygiene and healthy periimplant soft tissue. This type of freestanding retentive component may be advantageous for the hygiene maintenance of periimplant soft tissue.     

Simplified Technique for Orbital Prosthesis Fabrication: A Clinical Report

Loss of orbital content can cause functional impairment, disfigurement of the face, and psychological distress. Rehabilitation of an orbital defect is a complex task, and if reconstruction by plastic surgery is not possible or not desired by the patient, the defect can be rehabilitated by an orbital prosthesis. The prosthetic rehabilitation in such cases depends on the precisely retained, user‐friendly removable maxillofacial prosthesis. Many times, making an impression of the orbital area with an accurate record of surface details can be a difficult procedure. The critical areas are making a facial moulage, mold preparation, and attaching the retention device, particularly when eyeglass frames are used. This case focuses on these hindrance factors. A simple basket was used for the impression tray to obtain the facial moulage. A putty mold was used, and attachment of the prosthesis to a retention device was accomplished with positional distance. This method proves to be an economical and simple way of making an orbital prosthesis.     

Modified Bar Superstructure for an Implant-Retained Orbital Prosthesis

The success of a bar superstructure for an orbital prosthesis may be compromised by the placement and angulation of implants. The following technique describes a modification to a bar superstructure that provided the advantages of convenience, security, and consistent positioning even though one implant was lost and the angulation of implants limited accuracy.     

A Digital Method to Fabricate the Ocular Portion of An Orbital Prosthesis with A Smartphone Camera,Color Calibration and Digital Printing

Conventional techniques described in the literature for the manufacture of ocular prostheses are time‐consuming since they involve manual work. The use of technologies could improve this laborious process, providing better esthetic outcomes. This technique describes how to manufacture the ocular portion of an orbital prosthesis using a smartphone camera, color calibration with a tooth shade guide, and digital printing. This method allows clinicians to fabricate customized ocular prosthesis by using a photograph of the patient's eye, thus eliminating the need for hand‐painting and manual work, and reducing fabrication time.     

Prosthetic Rehabilitation of a Patient with an Orbital Defect: A Simplified Approach

Large oro-facial defects consequences in serious functional as well as cosmetic deformities. Acceptable cosmetic results usually can be obtained with a facial prosthesis. This article describes prosthetic rehabilitation of a 35 year-old female having a left orbital defect with HTV silicone material. A modified technique to fabricate an acrylic substructure in heat-polymerizing polymethyl-methacrylate to support silicone facial prosthesis was illustrated. The resultant facial prosthesis was structurally durable and esthetically acceptable with satisfactory retention. This technique is advantageous as there is no need to fabricate the whole prosthesis again in case of damage of the silicone layer because the outer silicone layer can be removed and repacked on the substructure if the gypsum-mold is preserved.     

Two-Piece Occlusion Rim for Screw-Retained Implant Prosthesis

The record base for a multiple, implant-supported, fixed prosthesis may be attached to the implants by screws. The screw attachment provides a stable record base for recording maxillo-mandibular relationships. Extraoral adjustment of the occlusion rim requires that it be unscrewed to allow removal from the mouth. The rim must be reattached with screws for the next intraoral evaluation. Although this cycle of removal and replacement provides stability, retention, and accuracy, it is time-consuming and inefficient. To resolve this problem, a two-piece record base/occlusion rim can be used. The screw-retained record base remains intraoral for the duration of the clinical appointment. The occlusion rim is designed to fit over the record base, with retention and stability, without screw retention. Use of the two-piece record base/occlusion rim facilitates convenient removal, adjustment, and replacement of the occlusion rim.     

A method for fabricating an implant-retained orbital prosthesis using the existing prosthesis

This article describes a time-saving technique for fabricating a new implant-retained orbital prosthesis using the patient's existing prosthesis. The location of the ocular component is transferred; the position and openings of the palpebral anatomic structures and the precise anatomic details of the existing orbital prosthesis are duplicated. Making the impression, fabricating the definitive cast, alignment of the ocular component, and completing the wax sculpture of the prosthesis are accomplished in one appointment.     

Orbital prostheses.

This article presents the steps used in fabricating an orbital prosthesis. Major considerations such as selection of the spectacle frame and the artificial eye, eye alignment, and clay modeling are emphasized to ensure an esthetically acceptable prosthesis. A simple technique for construction of wax templates for fabrication of orbital prostheses in acrylic resin also was described.     

Prosthetic Rehabilitation of a Marginally Resected Mandibular Arch With a Metal Reinforced Telescopic Overdenture

Success of the prosthesis after mandibular resection is related directly to the amount of the remaining bone and soft tissue present. The prognosis for mandibulectomy patients becomes less favorable as the size of the resection increases. Prosthetic rehabilitation for such patients is a challenge for clinicians. Without preprosthetic reconstructive surgery, denture fabrication for mandibulectomy patients becomes extremely difficult. Telescopic dentures is a modality of treatment consisting of an inner or primary telescopic coping which is permanently cemented to an abutment and an outer or secondary telescopic coping which is attached to the prosthesis. These copings protect the abutment from dental caries and thermal irritations and also provide retention and stabilization of the secondary coping. The secondary coping engages the primary copings to form a telescopic unit and it provides retention and stability to the prosthesis. This clinical report aims at utilizing the remaining natural teeth for a mandibular overdenture with telescopic coping.     

Early Prosthetic Management of Maxillectomy,Hemimandibulectomy Patient with a Lateral Mid Facial Defect: A Case Report

Maxillofacial prostheses for acquired defects have become more complex and sophisticated with advances in surgical, physical, and rehabilitative dentistry, but before planning, orofacial structures must be analyzed as to the specific cause and the consequent objectives of rehabilitation. Also retention of facial prostheses is very much challenging. Hence, we are presenting the fabrication of an interim prosthesis obturator and cheek prosthesis to restore the speech, help in deglutition and prevent drooling of saliva.     

Rehabilitation of a missing ear with an implant retained auricular prosthesis

Burns can leave a patient with a severely debilitating disability even after treatment. The objectives of burn rehabilitation are to minimize the adverse effects caused by the injury while rehabilitating the patient''s physical and psychological well-being, maximizing social integration. Long-term success of maxillofacial prostheses mainly depends on the retention. Extra oral implant retained prostheses have proved to be a predictable treatment option for maxillofacial rehabilitation. Replacement of a severely deformed external ear with burned tissues may be satisfactorily accomplished by a cosmetic prosthesis anchored by implants integrated in the skull. The use of such implants is now a well-recognized method for creating a stable result in maxillofacial rehabilitation. This case report describes a safe, simple and economical method for the rehabilitation of a patient with missing right auricle using an implant supported silicone prosthesis. The implant was placed in the mastoid region of the temporal bone. Reconstruction of the ear was done with auricular silicone prosthesis, retained using magnets incorporated in an autopolymerizing resin shim to decrease the weight of the prosthesis on a single implant. This method eliminates the need of tedious laboratory procedures and exact casting and fitting requirements of a metal substructure while minimizing the overall weight and cost of the prosthesis while maintaining adequate support, esthetics and retention of the prosthesis.     

Rehabilitation after Surgical Treatment for Retinoblastoma: Ocular Prosthesis for a 6‐Month‐Old Child

Maxillofacial prosthetic (MFP) rehabilitation can be especially challenging in a young, precooperative, or behaviorally compromised child presenting with an enucleated eye. Retinoblastoma is the most common intraocular malignancy in childhood and is one of the most common pediatric cancers. Treatment consists of enucleation (or removal of the entire globe) followed by placement of orbital implants. Unrestored anopthalmic sockets exhibit growth retardation and can lead to facial disfigurement. This report describes the challenges faced during rehabilitation of a 6‐month‐old girl with an anophthalmic socket due to enucleation for retinoblastoma. The objective of the MFP team was to provide a custom‐built, acrylic ocular prosthesis in as comfortable and atraumatic manner as possible. The case was a success and underscores the value of a multidisciplinary dental approach for the treatment of children with very special needs.

Functional Impression Technique for an Ocular Prosthesis

The loss of an eye is the most devastating, psychologically damaging experience for a patient. All hope to bring such patients back to their accustomed and comfortable life-style rests on a cosmetically acceptable prosthesis. An intra-orbital ocular prosthesis serves the purpose in those defects where the orbital margins are intact. Though the stock eye may match the natural eye’s iris and sclera in color, the fit of the prosthesis to the tissue bed may not be as good as desired. Herein, a functional ocular impression technique is presented to achieve a better fit of the prosthesis to the defect area. This technique aims to combine cosmetic excellence with comfort for greater benefit to the patient.     

Modified technique to fabricate a hollow light-weight facial prosthesis for lateral midfacial defect: a clinical report

Large oro-facial defects result from cancer treatment consequences in serious functional as well as cosmetic deformities. Acceptable cosmetic results usually can be obtained with a facial prosthesis. However, retention of a large facial prosthesis can be challenging because of its size and weight. This article describes prosthetic rehabilitation of a 57-year-old man having a right lateral mid-facial defect with intraoral-extraoral combination prosthesis. A modified technique to fabricate a hollow substructure in heat-polymerizing polymethyl-methacrylate to support silicone facial prosthesis was illustrated. The resultant facial prosthesis was structurally durable and light in weight facilitating the retention with magnets satisfactorily. This technique is advantageous as there is no need to fabricate the whole prosthesis again in case of damage of the silicone layer because the outer silicone layer can be removed and re-packed on the substructure if the gypsum-mold is preserved.     

Silicone Finger Prosthesis. A Clinical Report

The loss of all or part of a finger following traumatic amputation may have a negative impact on physical and psychological well being. An esthetic prosthesis can offer psychological, functional, and rehabilitative advantages. The success of a prosthetic restoration primarily depends on its retention. This clinical report describes an alternative method of retention by scoring the master cast of a partially amputated finger, thus enhancing the vacuum effect for the retention of the prosthesis. The methodology of treatment is also explained. Silicone material was used to provide function and esthetics.     

An alternative approach to combine orbital prosthesis and obturator: a case report

This report describes a different approach for diminishing the movements of orbital prosthesis during mimic movements and chewing function. Mechanical devices such as magnets are used to enhance the retention in case lack of the implants. However rigid fixation of obturator and orbital prosthesis can result in movements of the orbital prosthesis during mastication. In this case obturator and orbital prosthesis are combined by magnets. However this combination is not rigid because of an active part which provides movement. This active part allows movements in a space constructed in the acrylic base of orbital prosthesis. Thus, the movements that may occur on orbital prosthesis during chewing can be diminished by this simple mechanism. Due to the fact that designing such a mechanism that minimizes the movements of the orbital prosthesis contributes patient's comfort.
