A report of a novel approach for the management of paediatric mandibular fracture using a prefabricated adaptable surgical splint.

Paediatric facial fractures are relatively rare. The inherent elasticity of the bones with more of the cartilage than that of the mineralised bone accounts for this. The principles involved in the management of facial fractures are the same irrespective of the age of the patient; however, in children, the techniques used are necessarily modified by certain anatomical, physiological, psychological and feeding factors related to childhood and the parents. In an attempt to keep the treatment and fixation technique simple, the case, presented here, describes the management of a mandibular parasymphyseal fracture in a 16-month-old child with the use of a prefabricated adaptable surgical splint.

Assessment of Diverse Frenal Morphology in Primary, Mixed, and Permanent Dentition: A Prevalence Study.

AIM: The maxillary labial frenum is a normal anatomic structure with inherent morphological variations. It has various morphologies and types depending on the attachment of fibers. This study was conducted to access the frenal morphology and frenal attachment in primary, mixed, and permanent dentition. MATERIALS AND METHODS: This study includes 1,800 patients, in which 969 were males and 831 females, with 3-17 years of age and is equally divided into primary, mixed, and permanent according to age and dentition of patients. Morphology of maxillary labial frenum was examined and classified according to Sewerin's frenum typology and type of frenal attachment according to Placek's attachment. Data collected were entered into SPSS version 16 and were subjected to statistical analysis. RESULTS: Simple frenum is most prevalent in all the age groups followed by persistent tectolabial frenum (PTF) in primary dentition, frenum with a nodule in mixed dentition, and frenum with an appendix in permanent dentition. Type III frenal attachment is found in primary dentition followed by type II and type I in mixed and permanent dentition, respectively. There is a highly statistically significant difference in the type of frenal morphology and frenal attachment in all groups of dentition. CONCLUSION: The prevalence of simple frenum is increasing from primary dentition to permanent dentition, whereas PTF decreases as age increases. This study reveals a high prevalence of gingival attachment followed by papillary attachment. CLINICAL SIGNIFICANCE: The examination of frenal morphology and attachment is important before planning for any dental procedures to rule out the misdiagnosis and unnecessary surgical interventions.

Stress distribution & deflection in an Aramany class II obturator fabricated with cobalt-chromium & titanium alloys - 3D FEA.

PURPOSE/OBJECTIVES: The aim of the research was to develop a model that accurately represents an Aramany class II defect and its obturator prostheses fabricated with Cobalt Chromium alloy & Titanium alloy to compare the deflection and the stress distribution in the rehabilitated area. METHODS: Aramany class II defect and the obturator prostheses was generated geometrically utilizing ANSYS 14.5, both overlaid on each other to impressionist prostheses and the maxilla as one element. Meshing of models was carried out utilizing HYPERMESH software & materialistic properties were assigned. The 120 N load was constituted on the teeth in different directions. RESULTS: The stress distribution & deflection executed by ANSYS provided results that enabled the tracing of Von Mises stress and deflection field in the form of color veiled bands with standards in Mega Pascal (MPa). CONCLUSION: The study shows that Von Mises stresses are higher for the frame work fabricated with cobalt chromium alloy compared to Titanium alloy. The framework made of titanium alloy showed more deflection than cobalt chromium alloy. CLINICAL IMPLICATIONS: 3D FEA can be performed on a computer without putting any stress on the human body from technical materials, which is especially difficult for maxillectomy patients.

Liquid-supported dentures: a soft option-a case report.

Liquid-supported denture technique allows continued adaptation of denture to the mucosa both at resting and functional state. A complete denture prosthesis is unacceptable if it violates the foundation on which it rests. In this case, a technique for fabrication of a complete denture prosthesis that eliminates the disadvantages of tissue conditioners and soft liners (i.e., poor bond strength to acrylic, candidal colonization, etc.) and preserves the remaining tissues is described. Liquid-supported denture can be a permanent solution to some patients with problematic conditions like diabetes, xerostomia, atrophied ridge, and so forth.

Prosthetic rehabilitation of a patient with an ocular defect: a simplified approach.

Mutilation of a portion of a face can cause a heavy impact on the self-image and personality of an individual. Acceptable cosmetic results usually can be obtained with a facial prosthesis. This paper describes prosthetic rehabilitation of a 60-year-old male patient having a left ocular defect. A technique to fabricate heat polymerizing polymethyl methacrylate was illustrated. The resultant prosthesis was structurally durable and aesthetically acceptable with satisfactory retention. The importance of meticulous treatment planning to tackle the challenges faced in fabricating an ocular prosthesis is explained with the relevant literature.
