Prosthetic Rehabilitation of Edentulous Flabby Ridge using Modified Hobkirk Window Impression Technique: A Case Report Mobile denture-bearing tissues in the form of flabby ridges are susceptible to displacement under masticatory forces, leading to loss of peripheral seal. Conventional impression-making techniques may record the mobile tissue in a distorted state, adversely affecting the retention and stability of the definitive prosthesis. Hence, this case report describes a modified impression technique used to record the flabby edentulous ridge in an undisplaced state to avoid compression and rebounding of the mobile tissue. A 49-year-old male patient reported to the Department of Prosthodontics complaining of difficulty in chewing food due to missing teeth for the past one year. Intraoral examination revealed the healed edentulous ridges with flabby, displaceable tissue on the residual ridge crest with respect to the anterior segment in both maxillary and mandibular arches. Prosthetic rehabilitation using removable complete denture prosthesis was planned with definitive impressions made using modified Hobkirk technique. A modified impression technique used to record the flabby edentulous ridge in an undisplaced state to avoid compression and rebounding of the mobile tissue gave a satisfactory outcome. This technique is simple to implement and adheres to the principles of preventive prosthodontics. Periodic follow-up showed that the patient was satisfied with the prosthesis.

PURPOSEScarf is a long loose piece of cloth worn around the neck and shoulder. Despite cultural association of this apparel, it is part of numerous injury episodes of varying enormity. Entanglement of loose scarf in spoke wheels of bike, tricycle, belt driven machines like sugarcane juice machine, thresher, grinding machines, etc is observed both in social and industrial milieu. This study aims to investigate the scarf-related injuries at a major trauma center in northern India.

METHODSFrom June 2013 to May 2015, a hospital-based prospective observational study was done in patients who presented to a level 1 trauma center in northern India with the mode of injury involving scarf around the neck. Demographic profile, mode of trauma, contributing factors, injury pattern, and the early management as well as early complications were recorded.

RESULTSThere were 76 injuries directly related from scarf with the mean age of patients being 32.4 years. The most common primary factor involved was rotating wheel of motorbike/tricycle (46.1%), followed by belt driven machines (28.9%). The spectrum of injuries was diverse, including minor abrasions or lacerations (53.9%), large lacerations (15.8%), fractures and spine trauma (18.4%), mangled extremity and amputations (7.9%) and death (3.9%). More severe injury patterns were noted with belt driven machines.

CONCLUSIONScarf-related injuries constitute a sizable proportion of trauma, with varying degrees of severity. Devastating consequences in significant proportion of cases dictate the call for a prevention plan comprising both educational and legislative measures. Urgent preventive measures targeting scarf-related injuries will help reduce mortality and morbidity.
