Introduction: The bisphosphonate-related osteonecrosis of the jaw was first referred to in 2003. Bisphosphonates action is focused on the osteoclasts. The drastic inhibition of the osteoclastic function is harmful for the jaws which are the only bones of the human skeleton in relative contact with the external environment. The adverse effects of the bisphosphonate-related therapy include the pathology for which they are prescribed, the atypical fractures in pathological bone. Method: The aim of this research was to analyze the risk factors and the treatment methods in case of osteonecrosis of the jaws...

BACKGROUND: Determining and restoring physiological vertical dimension of occlusion (VDO) is the critical step during complete mouth rehabilitation. The improper VDO compromises the aesthetics, phonetics and functional efficiency of the prosthesis. Various methods are suggested to determine the accurate VDO, including the facial measurements in the clinical situations with no pre-extraction records. The generalisation of correlation between the facial measurements to VDO is criticised due to gender dimorphism and racial differences...

PURPOSE: Severe physical facial deformities due to surgical interventions can have significant psychosocial consequences to patient's relationships with friends and family and thus, has a considerable impact on their quality of life. We have developed a 3D prosthesis for a 56-year-old woman diagnosed with epidermoid carcinoma at the right hemiface, to improve her quality of life. METHODS: The patient started radiotherapy with modulated intensity. To deal with the advance of the process, a maxilectomy of supra structure with modified radical cervical emptying on the right hemiface was performed...

Interdisciplinary prosthodontics goes beyond our imagination into fields that have a direct effect on our total body health and quality of life. Removal of an eye has a detrimental effect on the psychology of the patient. Enucleation involves removal of the eyeball proper and leads to an enophthalmic socket with a shrunken eye, which has a crippling effect on patient's emotional and social life. Custom-made eye prosthesis simulates the characteristics of the companion eye and helps in restoring the normal facial appearance...

The present report describes the digital design of patient-specific milled abutments for the retention of osseointegrated facial prostheses by using digital technology. Patient imaging including surface scans of the patient's head, scans of the patient's definitive cast, and digitally designed prosthesis prototypes were combined to create a digital simulation of the patient. Using this simulation, patient-specific abutments were digitally designed, printed in 3-dimensions (3D), and finally copy-milled in titanium...

S C Ahila, S K Jagdish
The role of a maxillofacial prosthodontist in the treatment of facial defects cannot be underestimated. A multidisciplinary approach is required during the rehabilitation procedure to bring out effective results. Ancillary maxillofacial prostheses limit the patient's disability and improve function. These prostheses are inevitable in restoring the function, esthetics, general, and psychological health of the patients. This article reviews the various ancillary-maxillofacial prostheses and throws light on their historical development...

Facial nerve dysfunction is common in oculoauriculovertebral spectrum (OAVS). However, the course of the nerve has rarely been described. A 23-year-old woman with OAVS underwent excision of microtic ear remnants in preparation for an osseointegrated prosthesis and suffered iatrogenic transection of the facial nerve-the pes anserinus was within the subcutaneous tissue 15 mm posterior and 15 mm cephalad to the external acoustic meatus. The patient underwent primary nerve repair and regained nearly complete preoperative function...

We report an unusual case of a young Quarter Horse with a large dental fracture fragment displaced into the maxillary sinus, leaving an oroantral communication that caused food impaction and metaplastic calcification in the sinus and facial deformation with cutaneous fistulation. Oral extraction of a remaining tooth fragment from its alveolus was succeeded by a maxillary sinusotomy for removal of the abnormal sinus contents. Since the oroantral fistula did not heal spontaneously following the placement of a silicone dental prosthesis, minimally invasive transbuccal and transnasal endoscopic approaches were used to encourage closure of the oroantral fistula by alveolar granulation...

Free flaps based on static slings principles cannot provide esthetic and functional outcomes at a desired level in total or close to total lip loss. Therefore, dynamic methods have become a current issue in recent years and especially the idea of functional gracilis free muscle flap has been suggested. In this study, we present a case of a successful total lower lip repair with this flap.In a 78-year-old female patient who was diagnosed with squamous cell carcinoma involving the entire lower lip, bilateral modified radical neck dissection and full-thickness total resection with 1 cm surgical margin so as to include both commissures of the tumor were performed and then a free gracilis muscle flap was transferred from the same side...

Squamous cell carcinoma (SCC) of the head and neck can be treated with a combination of modalities. There is an esthetic and functional compromise with midfacial defects secondary to ablative surgery and adjuvant therapies for SCC. Osteoradionecrosis, tissue contracture, and trismus, are all negative side effects of treatment and can impact a patient's function and possibly their nutrition. In this report, we describe a procedure for fabrication of a prosthesis that provides cosmetic improvement and labial competence to maintain caloric intake...

Direct silicone printing may be applied to the fabrication of maxillofacial prostheses, although its clinical feasibility is unknown. The present clinical report shows an early application of a directly printed silicone prosthesis for the rehabilitation of a nasal defect. Two extraoral scanning systems were used to capture the face and the defect. The virtual construction of the nasal prosthesis was performed with free-form software. Two prostheses were printed in silicone and post-processed by manual sealing and coloring...

Occlusal and esthetic rehabilitation of jaw deformities in patients with partially edentulous maxilla are challenging procedures. This article describes a patient involving a skeletal Class III, 36-year-old male patient with a single bilateral anterior partially edentulous maxilla resulting from injuries sustained in a motor vehicle accident; his anterior teeth had been lost for more than 10 years. His lip protruded from the lateral view due to the proclined upper incisors and mandibular protrusion.Because of the facial deformity and inadequate prosthesis of the maxilla, the prosthesis had dropped out repeatedly...

During the 2017 IFOS international congress in Paris, a roundtable discussion on the topic of functional and aesthetic rhinoplasty was organised. Five experts, from the five continents and renown in the field of rhinoplasty, were brought together to discuss the issue from an international perspective and to put forward a consensus or on the contrary practical differences. Five questions were put to the experts beforehand to guarantee independent answers, which were then discussed during the roundtable. The questions were the following: - What are the age limits for achieving a rhinoplasty? - Do you use objective measurements before, during and after surgery? (facial landmarks, airflow, peroperative measurements) - How do you manage the preoperative general information and computer imaging of the patient? - What are the indications in your practice to perform a CT-scan or endoscopic examination before doing a rhinoplasty? - What kind of graft or prosthesis do you use for an augmentation rhinoplasty? This paper offers a synthesis of the roundtable based on the experts' answers to the different questions...

The objective of this article is to show a case of fronto-orbital reconstruction with prefabricated polymethyl methacrylate prosthesis. A 35-year-old male with alleged history of trauma following road traffic accident 3 months back reported with unaesthetic scar and deformity in right supraorbital region to us. As there was no functional deformity, the management was aimed at correcting the contour and esthetic only. The correction was achieved by overlaying the defect with a polymethyl methacrylate implant fabricated over a three-dimensional stereolithographically printed rapidly prototyped model...

Current approaches to orbit reconstruction are based on the assumption of facial symmetry and surgeons' experiences, and the reconstructed orbits are not precise. Through computer-assisted volumetric quantitative analysis, the volume of the bony orbit, and the volume of the soft tissues in both the anophthalmic orbit and the contralateral orbit are calculated in 39 anophthalmic patients. The rib graft is used for orbit reconstruction; the dosalis pedis flap and lipo-injection were used for soft tissue reconstruction and skin socket reconstruction...
