Addition silicones have revolutionized the field of fixed prosthodontics because of their dimensional stability, sufficient tear strength and excellent detail reproduction. This review study aims to provide a detailed description of the essential variables to be taken into account during the process of making addition silicone impressions in fixed prosthodontics. These variables include the selection of appropriate tray type, size, and fabrication; the use of tray adhesive; gingival displacement techniques; manipulation of the impression material; the choice of the impression material's viscosity; impression techniques; and the proper insertion, removal, disinfection, and pouring of the cast.

Finite element analysis (FEA) is one of the best methods for evaluating the stress distribution of restorations, such as fixed partial dentures. The development of resin cement has transformed prosthesis bonding and retention properties. Resin-bonded fixed partial dentures (RBFPD) have been considered minimally invasive treatment options for the prosthetic rehabilitation of single missing teeth.

Materials And Methods: In this randomized clinical trial, 45 patients with myofascial pain were diagnosed and were randomly assigned into three groups of 15 patients each. Group 1 - subjects were given hard splint, Group 2 - soft splint, and Group 3 - liquid oral splint for 3 months.
Objectives: The objective of this study was to evaluate stress distribution in the dentin and alveolar bone created by load application on simulated endodontically treated teeth with two different esthetic posts.
Materials And Methods: A finite element model was made and elastic moduli and poissons ratio of all the materials fed to the software. For both the models, a 100N force was applied on the lingual surface of the tooth at an angle of 45°.
The aim of this study was to evaluate and compare the linear dimensional change, surface hardness and surface roughness of the refractory casts poured against different duplicating media. Polyvinyl siloxane and Agar-agar were used for duplicating the stainless steel die. Sixty refractory models were prepared which were divided into two groups: I and II with 30 samples each respectively.

Materials And Methods: Sixty-three porcelain pellets were prepared and were divided into 9 groups. Three surface treatment and two bonding agents were evaluated.
Objective: A review of literature for ocular prosthesis is presented along with a case report of a geriatric patient.
Review Of Literature: The evolution of ocular prosthesis, materials and methods, fabrication techniques for custom and stock eye prosthesis, delivery and after care for the ocular prosthesis are reviewed.
Case Report: A 74-year-old female patient who had undergone enucleation of her right eye was restored with a stock ocular prosthesis.
The article presents the case of a patient who was practising Yoga (Kunjal kriya) which led to dental erosion. Dental erosion can be due to extrinsic or intrinsic causes. The intrinsic causes include vomiting due to anorexia nervosa, regurgitation due to abnormality in gastro-intestinal tract or rumination.
