If we ignore delayed onset of anesthesia of Gow gates technique, it is found to be more reliable, beneficial and have higher success rate than classical inferior alveolar nerve block technique.
Loss of continuity of the mandible destroys the balance and symmetry of mandibular function, leading to altered mandibular movements and deviation of the residual fragment towards the resected side. Prosthodontic treatment along with physical therapy may be useful in reducing mandibular deviation and improving masticatory efficiency. Numerous prosthetic methods are employed to minimize deviation and improve masticatory efficiency which includes implant supported prosthesis, mandibular guide flange prosthesis, and palatal based guidance restoration. This article describes rehabilitation of hemimandibulectomy patient using twinned teeth (two rows of teeth) on the unresected side in the maxillary edentulous arch for whom implant supported prosthesis, mandibular guide flange prosthesis or palatal based guide flange prosthesis cannot be fabricated to improve the masticatory efficiency.
The management of highly resorbed ridge has always posed a challenge to the prosthodontist for years. Obtaining consistent mandibular denture stability has long been a challenge for dental profession. In particular, Atwood's Order V and Order VI pattern of bone resorption is associated with difficulties in providing successful dentures. Stability of lower denture in such cases is usually the distinguishing factor between success and failure. This article outlines a combination of different impression techniques to improve mandibular denture stability in an atrophic mandibular ridge, keeping in mind the prevention of further ridge resorption.
Congenital absence of teeth is a hereditary phenomenon passed through generations by an autosomal dominant pattern. Such a patient often presents with poor esthetics, mastication and disturbed social behavior. Here is a case of partial anodontia with agenesis of 15 teeth, which has been treated by providing maxillary complete overlay denture and mandibular overlay removable partial denture.
Atrophia idiopathica mucosa oris is an oral fibrosing disease resulting in marked rigidity and an eventual inability to open the mouth or had limited mouth opening. Patients with limited mouth opening are a common occurrence in prosthodontic practice. The majority of these patients can be treated with exercise and stretching movements before impressions are made. Some will not respond to these procedures because of facial scarring and surgical manipulation of the facial muscles. This article presents an impression procedure for overcoming difficulties encountered in such reduced mouth opening patients that can be assembled intraorally, disassembled intraorally, and reassembled extraorally.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
