Applications of PEEK in Dentistry

2020-11-18T15:36:15+00:00

Introduction of Polyetheretherketone (PEEK) Polyetheretherketone (PEEK) is a synthetic, tooth colored polymeric material that has been used as a biomaterial in orthopedics for many years. The monomer unit of etheretherketone monomer (Fig. 1) polymerizes via step-growth dialkylation reaction of bis-phenolates to form Polyetheretherketone. PEEK can modified either by the addition of functionalized monomers (pre-polymerization) or post-polymerization modifications by chemical processes such as sulphonation, amination and nitration. The titanium and its alloys have elastic modulus significantly higher than bone and resulting in severe stress-shielding and failure. In 1978, it was developed by a group of English scientists. Later PEEK was commercialized for [...]

Guided Surgery Part 1: Conventional surgical stent

2020-10-07T13:48:11+00:00

Introduction Dental implants have become a treatment options widely used for the replacement of lost teeth. The development of dental implants has had a major impact on the patients and the implant supported oral restoration has become an increasingly used treatment option for partially edentulous and completely edentulous patients, also even in patients with severe bone loss and in locations which all previously considered unsuitable for implant placement has been made possible by means of bone augmentation, regeneration and soft tissue regeneration procedures. The success of dental implants in the treatment of patients is directly related to patient evaluation and [...]

A Journey to Science: Understanding Materials Properties PART 2 – Lithium Disilicate

2020-09-08T19:59:38+00:00

A Journey to Science: Understanding Materials Properties PART 2 - Lithium Disilicate Introduction Glass ceramics were first developed by Corning Glass Works in the late 1950s. Over time, manufacturers started adding filler particles to the base glass composition to improve mechanical properties, such as strength and thermal expansion and contraction behavior. Crystalline filler particles can be added mechanically to the glass, for example by mixing together crystalline and glass powders before firing. In a more recent approach, the filler particles are grown inside the glass object after the object has been formed. After forming, the glass object is [...]

A Journey to Science: Understanding Materials Properties PART 1 - Zirconia Introduction When restoring a tooth, the clinician faces what material should be used for the restoration. The major factors that may influence the final choice are esthetics and strength of prostheses. Metal ceramics have been conventionally used as reliable materials. However, due to the request of esthetic dentistry, all ceramic prostheses are replacing metal based restorations more and more. Zirconia has been used in prosthetic dentistry for the fabrication of crowns and fixed partial dentures for more than 15 years, in combination with CAD/CAM techniques. Zirconia (ZrO2), [...]

Digital Complete Denture: Where We Are and What’s Next

2019-12-06T21:10:06+00:00

Introduction According to the American Dental Association in 2014, more than one third of Americans did not visit a dentist at all in the past year. Infrequent or inconsistent dental health care puts patients at risk of tooth loss due to advanced caries or periodontal disease. Unfortunately, despite improvements in dental technology and science, the total number of patients who are becoming edentulous has not decreased in recent years.According to prospective studies in the United States, the number of patients who are fully edentulous in one or both jaws will continue to increase, from 33.6 million in 1991 to almost [...]

A Review of Digital Impression Technology

2019-12-06T21:07:28+00:00

1. Conventional Impression Technique, Digital impression Technique Since the eighteenth century, conventional impression techniques have been used to fabricate dental models. However, conventional impression techniques might have some errors regarding volumetric changes of impression materials and expansion of dental stone. Also, conventional technique is much influenced by the proficiency of practitioners. To overcome these difficulties, Digital impression was developed for dental practice with numerous advantages for practitioners. CAD/CAM was first introduced to Dentistry for single unit restorations about thirty years ago, and it has substantially contributed to advancement in technology in the last decade. Nowadays, Intraoral Scanner (IOS) and CAD/CAM [...]
