Back to Basics:Gold Occlusal Surfaces for Fixed-Complete Dentures
Article Date: Feb 12, 2016 Vol 15, No 2
Sabrina Garcia-Gazaui,Michael Razzoog,Berna Saglik & Marianella Sierraalta

Acrylic resin artifi cial teeth on fi xed complete dentures often exhibit rapid occlusal wear. The wear has been reported to lead to loss of chewing effi ciency, loss of vertical dimension of occlusion, and at times temporomandibular joint disorders. Different articles have described methods using varying materials to construct and replace occlusal surfaces of acrylic resin denture teeth. Porcelain surfaces are more stable against wear but tend to chip and fracture. Light-cured composites have become popular because they offer a less expensive and chair-side approach. Yet, even though the wear properties have been improved, composite will wear the opposing dentition in a dramatic fashion. In the past, occlusal metal surfaces have been successfully used to prevent wear and increase chewing effi ciency for complete and removable partial dentures. However, because these methods are time-consuming, costly, and sometimes considered to be unesthetic their use has diminished. This case report describes a treatment where gold alloy onlay occlusals have been used to delay acrylic wear in opposing implant fi xed complete dentures.

Effective Collaboration between Dentist and Technician
Article Date: Nov 27, 2015 Vol 14, No 9
Daniel Edelhoff

In addition to a bite registration, facebow transfer and impressions, intraoral and extraoral photos form the most important key in the communication between dentist and dental technician. The importance of photographic communication is particularly significant if the dentist and dental technician collaborate with each other from distant locations and have to fulfill demanding aesthetic and functional requirements. Photos are not only used for the initial transfer of information to conduct an aesthetic and functional analysis on the basis of a wax-up, but they also play a significant part in many other steps of the restorative process, such as in the clinical evaluation of the proposed restoration (mock-up) and in the shade selection of the tooth and preparation.

ThermoSens is Setting a New Benchmark in Flexible Dentures
Article Date: Nov 27, 2015 Vol 14, No 9
Daniel Edelhoff

This is Vertex’s view of their thermoplastic denture base material. Let's have a look at this fantastic material and see why this material is so positively different to the traditional nylon materials such as Valpast, Flexite, TCS, FRS etc. Thermoplastic (melt-when-heated and harden-when-cooled) materials are not new to dentistry, in fact, they were developed as far back as 1953; only sixteen years after heat curing acrylic was developed.

Herbst bite-jumping hinge – but,of course!
Article Date: Sep 21, 2015 Vol 14, No 7
Michael Röhnisch and Thomas Braun

Professor Emil Herbst, the inventor of the so-called Herbst bite-jumping hinge, first presented his invention at the 5th International Dental Congress in 1905 in Berlin. The main indication today is the correction of the skeletal Class II malocclusion. The inventor himself described the appliance as a "retention hinge", which shows that it was not used exclusively to correct distoclusions.

Fully edentulous rehabilitation
Article Date: Jul 03, 2015 Vol 14, No 6
Phil Reddington and Lee Mullins

Figures 1 and 2 show the inter-oral situation after successful implant placement. Figure 3 shows the result of the provisional stage restorations two acrylic transitional bridges on titanium cylinders screwed into the implant fixtures. After three months of assessing the osseous integration, it was decided the patient was ready to move onto the next phase of the treatment. Two tripodised wax bites (Figures 4 and 5) and verification jigs were manufactured and sent out to the clinic and placed into the implant sites (Figure 6).

Applications of removable dentures in biocompatible resins
Article Date: Apr 24, 2015 Vol 14, No 4
Massimiliano Petrullo

In this article are described theapplications in removable dentures ofa new generation of visible lightcuring resins (VLC), which today canreplace completely the self or heatcured poly-methylmethacrylate(PMMA) in all the fields in whichthey are employed. These proceduresare included in the applied researchprogram TRE, which involves the useof these materials in fixed denturesand orthodontics as well. In this workthe aspects concerning the removabledentures will be examined,underlining the key differencesbetween VCL and PMMA materials.

Prosthetic Solutions in Acetal Resin

Claudio Mengani

In recent years we have seen anincreasing number of mouths withsignificant abrasion of the occlusal(due to parafunctional habits), andwhere there is a strong reduction ofthe vertical dimension, it is possiblethat the meniscus to the glenoid issubjected to enormous stress, withpossible temporomandibulardysfunction. Patients with theseproblems often have the oval of theirfaces squashed. At the clinical level, itis possible to encounter the onset ofarticular noises when opening and/or closing the mouth, and pain that canlimit the dynamics of the mandible. Many articles have been written onthese problems in which it is explainedhow to improve,

Considered bridge design "Art of Prosthetics" Complete Dentures
Article Date: Apr 02, 2015 Vol 14, No 3
Boris Jäger, Christoph Fuchs

The quality of complete dentures varies a lot. Inaccuracies which emerge during the preparation of the teeth or overlooked details during their basic production have a significant impact on their fit and function – and not least on the quality of life of the wearer. Using photos,Boris Jäger demonstrates the procedure for the production of these everyday examples of the Art of Prosthetics.

Are all soft lining denture materials created equal?
Article Date: Apr 02, 2015 Vol 14, No 3
Nancy Tomkins DT(dip), DD, FCAD

Keeping patients comfortable with ‘conventional’ dentures that rest on less-than-ideal ridges is becoming increasingly more difficult. Severe atrophic ridges and thin mucous membrane areas are a daily challenge for denturists because patients expect comfort from their dentures, despite their compromised oral condition. Although dental implants are the optimum treatment option, many patients choose not to have implants placed for a number of reasons. In such cases, an alternative must be found to assist the patient. Although soft lining material is in no way a substitute for dental implants, it is an attempt to keep the patient as comfortable as possible.

The Suitable Treatment Plan
Article Date: Feb 25, 2015 Vol 14, No 2
Jim Collis, CDT

Determining the appropriate dental treatment plan is invariably a balancing act. There must be a balance between the patient’s desire to improve the appearance and function of their teeth within their financial budget with the practitioner’s concern for restoring the patient’s full mouth to a healthy and manageable state based on the feasible treatment alternatives developed as a result of a comprehensive oral examination. In this case study, a female patient who initially sought only to “fix” the esthetic appearance of her four upper anterior teeth eventually opted for a more comprehensive and more suitable treatment plan based on the results of a thorough oral examination.

Considered Bridge Design
Article Date: Feb 25, 2015 Vol 14, No 2
Cesare Ferri, CDT

When creating a screw-retained implant-supported bridge, careful analysis of all the parameters influencing the restoration (and well thought-out design) constitute the basis for accurate planning to achieve reliably predictable results. Cesare Ferri explains how this approach enables dental professionals to achieve restorations that will stand the test of time.
