Achieving primary stability in dental implants is crucial factor for accomplishing successful osteointegration with bone. Micro-motions higher than the threshold of 50 to 100 μm can lead to formation of fibrous tissue at the bone-to-implant interface. Therefore, osteointegration may be vitiated due to insufficient primary stability. Osseointegration is defined as a direct and functional connection between the implant biomaterial and the surrounding bone tissue. Osseointegration development requires an initial rigid implant fixation into the bone at the time of surgery and a secondary stage of new bone apposition directly onto the implant surface. Dental implants function to transfer the load to the surrounding biological tissues. Due to the absence of a periodontal ligament, its firm anchorage to bone, various forces acting on it and the presence of prosthetic components, they share a complex biomechanical relationship. The longevity of these osseointegrated implants depend on optimizing these complex interactions. Hence, the knowledge of forces acting on implant, design considerations of implant and bone mechanics is essential to fabricate an optimized implant supported prosthesis.
Digitization in removable Prosthodontics offers multiple advantages such as digital surveying, designing the framework with components and obtaining a 3D printed resin framework which can be tried intraorally and cast using conventional techniques, teeth arrangement. This technology is time-saving, highly accurate, also allows digital archiving of casts. This case report presents utilization of digital techniques and conventional protocols in rehabilitation of a bilateral posterior edentulous mandibular arch with an attachment retained cast partial denture.
Severely resorbed completely edentulous maxillary and mandibular arches from long-term complete edentulism may pose a treatment challenge for the treating prosthodontist. The loss of teeth, over a period of time, can lead to gross facial disfigurement and also has great psychological effect. The loss of teeth also has effect on the musculature and supporting tissues which may lead to muscle wasting and dystrophy. Ever since its introduction in 1971, Transcutaneous Electrical Nerve Stimulation (TENS) has been used in dentistry for various treatment modalities and it is especially indicated in management of tempo-mandibular dysfunctions (TMDs). TENS being a non-invasive, non-technique sensitive, and easy to use technique has evolved rapidly over the years as an adjunct in management of various dental therapies. Two case reports of completely edentulous patients are presented here, where ultra-low-frequency-TENS (ULF-TENS) was used as an aid in cameo surface recording and customizing the magnet retained cheek plumper within the physiological and functional limits of the orofacial musculature complex for rehabilitation with complete denture prosthesis.
Digitization has slowly become the new conventional technique today offering multiple advantages, its application in the field of implantology and fixed prosthodontics has been time tested, and its gradually being utilized in removable prosthodontics also. Digitization allows digital surveying, designing the framework with components, and obtaining a 3D printed resin framework, which can be tried intraorally and cast using conventional techniques. This technology is time-saving, highly accurate, also allows digital archiving of casts. This case report presents rehabilitation of a partially edentulous mandibular arch opposing completely edentulous maxillary arch using digital technology and casting using conventional technique.
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.
