Maxillofacial orosthesis materials: A review

As the human face constitutes a center of attention in human relationships, the emotional pressure because of facial disfigurement can produce a high degree of handicap. These disfigurements can be congenital deformities such as cleft lip, cleft palate or acquired deformities such as accidental injuries. The rehabilitation needed is more because of patient’s psychological and emotional demands rather than their physical deficits. The purpose of this article is to give a piece of in-depth knowledge and discussed the various maxillofacial materials and their recent advances. Although the current clinical scenario concerning the field of a maxillofacial prosthesis is promising, improvement in material and techniques to be expected in the future to have better results

Brief on posterior palatal seal area

Accurate recording and duplicating of posterior palatal seal is the vital procedure which contributes to the success in denture retention and subsequent treatment of edentulous patient. The responsibility of recording posterior palatal seal lies on the clinician and not the lab technician. Locating and designing of posterior palatal seal after thorough understanding of the anatomic and physiological boundaries of the region. The diagnostic evaluation and placement of posterior seal are often given only minor attention in complete denture construction. The aim of this article is to supply adequate information on posterior palatal seal, problems encountered while recording posterior palatal seal for longevity of complete denture treatment. &nbsp

Precision attachments: A review

The lack of sta­bility and retention together with a decrease in chewing ability are the commonly problems experienced by many edentulous patients with their den­tures and removable partial dentures. To overcome this problem and the desire to balance between func­tional stability and cosmetic appeal gave rise to the development of Precision attachments. Precision attachments are small interlocking devices to connect prosthesis and abutments that offer a variety of solutions to the challenge of balance between functional stability and cosmetic appeal. Precision attachments have wide applications, used in fixed removable bridge, removable partial dentures, overdentures, implant retained overdentures, and maxillofacial prosthesis. This article discusses about the various precision attachments used in treating edentulous and partially edentulous patients

Clinical epidemiological concerns and the geriatric prosthodontic patient

Investigations into the oral health of the elderly leave little doubt that disease and dysfunction galore, though there is some disagreement about how clinical findings translate into treatment needs. The disabled and the institutionalised appear to be the most vulnerable, whereas dentists appear to be uninterested in providing services outside the scope of traditional dental practice. As a result, the oral health concerns of the elderly, particularly those relating to prosthodontic treatment, remain largely unaddressed

Steps in digital denture fabrication

Fabricating a complete denture in a conventional manner may be complicated and difficult. The purpose of this presentation is to describe the benefits of a fully digital workflow and fabrication procedure of complete dentures based on digital impressions of edentulous jaws. The digital data for the workflow were acquired using an intraoral scanner and were then used to design the denture base and teeth. The resulting data were exported to a 3D printer or a milling machine for denture fabrication. The high accuracy of digitalized dental fabrication has been proved by several studies compared to conventional methods .CAD/CAM fabrication of complete dentures based on digital impressions of edentulous jaws obtained using an intraoral scanner. By this method the occurrence of human processing errors, inaccuracies, and multiple clinical appointments can be avoided

Hinge axis recording of the temporomandibular joint

The temporomandibular joint is called as ginglymoarthrodial joint. It is a complex joint in which two basic movements of the mandible can be distinguished. Rotary or hinge like movement taking place between the articular disk and condyle in the lower compartment of the temporomandibular articulation. Various studies have shown that an arbitrary location of the hinge axis is an acceptable alternative to its accurate location. With the availability of easy to use ear piece facebow, locating and transfer of hinge axis to the articulator is an easy and quick procedure.  Precision is the key to prosthodontics and it is thus imperative that restorations are made as accurately as possible

Stereolithography in implant placement: A review

Stereolithography (SLA), the first form of additive manufacturing, creates 3D objects by selectively solidifying liquid resin via a photopolymerization reaction. Stereolithography has gained popularity due to its ability to fabricate objects with high accuracy and in a wide range of materials. SLA has undergone four generations of major technological innovation since its invention in the 1980s. As a result of these advancements, a diverse range of stereolithography systems with dramatically improved resolution, throughput, and material selection for creating complex 3D objects and devices is now available
