The purpose of this study is to report a case of full-mouth rehabilitation on six endosseous implants loaded following the standard procedure. It was decided to insert six implants in the maxillary and six implants in the mandibular arch in a patient with no systemic disease. The surgery was performed with the patient under local anesthesia with lignocaine and 1:100,000 adrenaline. Implant stability was sufficient (35 N/cm measured with a torque spring) for all 12 implants. An impression is taken in the open tray with a silicone impression material. Vertical dimension for rest and occlusion was checked with wax occlusal rims placed in the mouth. Interocclusal records were made with the metal framework in place. The final restoration was realized with ceramic layering completed. Good impressions and meticulous attention to detail are crucial for a successful implant-supported fixed prosthesis.

Aims:The aim of this study was to evaluate the marginal fit and surface roughness of complete cast crowns made by a conventional and an accelerated casting technique.Settings and Design:This study was divided into three parts. In Part I, the marginal fit of full metal crowns made by both casting techniques in the vertical direction was checked, in Part II, the fit of sectional metal crowns in the horizontal direction made by both casting techniques was checked, and in Part III, the surface roughness of disc-shaped metal plate specimens made by both casting techniques was checked.Materials and Methods:A conventional technique was compared with an accelerated technique. In Part I of the study, the marginal fit of the full metal crowns as well as in Part II, the horizontal fit of sectional metal crowns made by both casting techniques was determined, and in Part III, the surface roughness of castings made with the same techniques was compared.Statistical Analysis Used:The results of the t-test and independent sample test do not indicate statistically significant differences in the marginal discrepancy detected between the two casting techniques.Results:For the marginal discrepancy and surface roughness, crowns fabricated with the accelerated technique were significantly different from those fabricated with the conventional technique.Conclusions:Accelerated casting technique showed quite satisfactory results, but the conventional technique was superior in terms of marginal fit and surface roughness.

Resorption of mandibular ridges is a multifactorial and biomechanical disease that is chronic, progressive,irreversible, and cumulative leading to loss of sulcular depth, vertical dimension loss, and decreased lowerfacial height. Some common neurological, hormonal, and metabolic disorders affect the adaptability ofdentures, and this can be diagnosed by a trained prosthodontist with proper history-taking and clinicalexamination. The denture becomes passive due to complex neuromuscular control and causes difficultiesin impression-making, mastication, and swallowing, which in turn leads to loss of retention and stability incomplete dentures. The loose and unstable lower complete denture is one of the most common problemsfaced by denture patients. One of the methods used to solve this problem is the neutral zone technique.Neutral zone technique is long being used for the management of severely resorbed mandibular ridges. Thepiezography technique, a special functional approach is described in order to overcome the difficulties of themandibular denture. Piezography, prosthetic space recorded by pronunciation, can be used as a reference forarrangement of artificial teeth and polishing surface of a denture.
