Analysis of behavior of the wear coefficient in different layers of acrylic resin teeth.

Statement Of Problem: Analysis of the wear coefficient (k) of the superficial and deep layers of acrylic resin teeth can help predict denture durability, but little has been published on the wear coefficient of denture teeth.

Purpose: The purpose of this in vitro study was to determine the k value for the superficial and deep layers of the acrylic resin teeth of 6 different brands by using the fixed-ball microabrasive wear method.

Material And Methods: Six artificial tooth specimens of 4 commercial brands were tested: Artiplus IPN (Ar), Biotone IPN (Bi), Magister (Ma), Premium (Pr), Trilux (Tr), and SR Vivodent (Vi).

Survival rate of titanium-zirconium narrow diameter dental implants versus commercially pure titanium narrow diameter dental implants: A systematic review.

Background: Despite the existence of several studies validating the use of narrow diameter implants, most of them are based on pure Ti alloys. There is few clinical evidence of the success of TiZr narrow diameter implants (TiZr NDIs) regarding survival rate (SR) and marginal bone loss (MLB).

Purpose: The aim of this review was to systematically assess SR, as well as MBL of TiZr NDIs compared to commercially pure titanium narrow diameter implants (cpTi NDIs).

A 5-week Non-Surgical Approach towards Denture Induced Hyperplasia.

Background: Despite the standard approach towards denture-induced hyperplasia being surgery, as elderly population increases the systemic problems are carried along. Thus, surgery might be risky for patients with medical conditions.

Objective: In this report, a patient with severe inflammatory papillary hyperplasia, medical problems and dental fear was treated with a 5-week nonsurgical protocol.

Different Occlusal Schemes in a Persistent Protruding Complete Denture Wearer.

Different types of artificial teeth and occlusal designs can be used in complete dentures. Bilateral balanced occlusion, lingualized occlusion, canine guidance, and monoplane are the main occlusal designs; however there is no agreement on which tooth arrangement is ideal for achieving success in complete dentures. This report presents an alternative for persistent involuntary protruding complete denture wearers through the use of artificial teeth with higher cusps.

In Vivo Comparison of the Masticatory Efficiency of Artificial Teeth with Two Different Cusp Heights in Complete Dentures: A Preliminary Study.

Purpose: The goal of complete denture rehabilitation is to restore facial esthetics and masticatory function to edentulous patients. Several types of artificial teeth with different occlusal anatomy are available. Theoretically, teeth with a higher cusp height provide improved masticatory efficiency.
