A good quality impression is only obtained when we have a thorough knowledge of materials, their properties and techniques for their best manipulation. In order to do so spacers are advocated for optimal thickness of impression materials in the custom tray to get the most accurate impression. There are vast number of impression techniques available in the field of Fixed Prosthodontics. Every technique has its own advantages and disadvantages, but still no impression technique is perfect with all the qualities inherent in it. The present review article discusses various impression techniques and their use in Fixed Prosthodontics.
General and oral health is a fundamental right of human being. Good health is achieved by assimilation of healthy diet and this further helps in maintaining health of oral hard (teeth) and soft tissues. Many age related diseases are highly influenced by nutrition. Improper nutrition not only affects physical appearance but also it affects psychological status of patient. Chronic disease and most oral diseases share common risk factors. Diet plays a key role in disease prevention, as poor diets have been linked to illnesses , such as osteoporosis, atherosclerosis, and bowel disease. Prosthodontist is a geriatric dentist who interacts with more number of older people as compare to other profession. Therefore, the major role for a prosthodontist is to guide the older people regarding malnutrition, balanced diet and age-related diseases. In this literature review the outlines of nutrition, basic requirements of nutrition associate with aging have been discussed.
The power of beauty to modify perception and behaviour in our colleagues and peers, friends and family has led to self rejuvenation making it an important aspect of our industry. In today’s world, facial appearance is one of the most important factors influencing our perception of beauty and attractiveness. The face is an integral aspect of a person’s identity and a visible marker of one’s age. Therefore, a person’s autonomous decision is an indicator for esthetic treatments that will improve their self-image, self-esteem and appearance to others. Botox injections are noted primarily for the ability to reduce the appearance of facial wrinkles. They're also used to treat conditions such as neck spasms (cervical dystonia), excessive sweating (hyperhidrosis), an overactive bladder and lazy eye. Dental health care professionals have started considering facial areas in relation to esthetic dentistry as dentists are familiar in this area than any other healthcare practitioner. This article gives you an insight into what is botulinum and how does it work, dental uses of Botox, non dental uses and dermal fillers that are becoming a very popular part of cosmetic dentistry known for their great ability in diminishing the signs of aging in the skin.
A fibrous or flabby ridge is a superficial area of mobile soft tissue affecting maxillary or mandibular alveolar ridges. It develops when a hyperplastic tissue replaces the bone, often seen in long-term denture wearers and clearly related to residual alveolar ridge resorption. The prevalence studies have shown that it most commonly affects the upper anterior region in denture wearers and affects edentulous maxilla (24%) and edentulous mandible (5%) when alveolar bone is replaced by hypertrophic soft tissues. 1 The displacement of this mobile tissue occurs easily during impression making causing distortion and also during mastication resulting in loss of peripheral seal. 2 Although these movable tissues does not provide good retention but should be recorded to ensure good support. 3,4 Also, when the new denture is adjusted into the mouth, patient's complains of pain caused by compression of tissues between the denture and the bone. Therefore, the intaglio surface of the dentures or the surface from where pressure is transmitted should have maximum possible area to reduce pressure on the oral mucosa. During impression making this mobile tissue should be recorded without distortion using special techniques that would provide for adequate retention, stability and support in a complete denture. 5 Flabby ridges have also been reported in cases with maxillary complete dentures opposing mandibular natural teeth. In 1972 Kelly described the term " combination syndrome to the changes in patients wearing maxillary complete dentures opposing mandibular anterior teeth. 6 The case presented here describes a special technique for such tissues for successful esthetic, functional and phonetic rehabilitation of an edentulous patient with maxillary anterior flabby tissue since conventional mucocompressive and muco-static impression techniques are not suitable for such cases, as the displaceable soft tissue exhibits 'recoil ' upon compression. 7
Implant abutments are artificial devices that are connected to the dental implants after the healing process is over. The abutments are used to attach a crown, bridge, or removable denture to the implant fixtures. Accurate prosthodontic rehabilitation is the key factor for providing the long-term success and the survival of osseointegrated implants. A precise fit of the implant is crucial since microgaps at the implant-abutment interface allow for microbial colonization, which can lead to peri-implant tissue inflammation. Polyetheretherketone (PEEK) has been used for academic investigations and commercialization of several dental devices, such as dental implants, abutments, healing caps, orthodontic braces, and most notably denture prosthetic frameworks.
