A simple, esthetic & inexpensive technique for a custom implant abutment

February 18, 2009

In implant reconstruction, the dimension from the implant platform to the crest of tissue, especially in esthetically critical areas, is often more than 2 mm. Many implant manufacturers supply a straight abutment for cement with the implant, which significantly can reduce the cost to the dentist. However, these abutments tend to have a margin about 1 mm tall, which limits their use to relatively thin tissue.

The ‘All-on-4’ implant concept for edentulous jaws

February 18, 2009

The efficacy of dental implant treatment is well-documented and its further development includes protocols for simplifying the procedures. The immediate function protocol is a powerful simplification as it allows the complete rehabilitation to be finalized within the same procedure.1–29 The fact that four implants is an optimal number for complete-arch prosthesis is an important further simplification. Provided the implants are placed as 'cornerstones'—two posteriorly and two anteriorly30,31—and they are well-anchored, the probability for success is high.32,33 It has also been demonstrated that tilting of implants might be advantageous as longer implants may be placed with good cortical anchorage in optimal positions for prosthetic support and reducing the length of the cantilever.34–36

The importance of gingival health in a functional cosmetic case

February 18, 2009

Complete dentistry is the aesthetic and occlusal harmonisation of the teeth with the gingiva, lips, and face. As dentists, we can directly affect the aesthetics of the teeth and gingiva. However, we can also indirectly affect the lips and face by how we design teeth to sit in the oral cavity.

New smile, new life—innovative technologies and techniques can transform a smile

February 18, 2009

An actor-turned-director came to our practice from www.denturewearers.com. He was seeking a solution to enhance and reconstruct his smile. Over the past several years, he had noticed his face slowly ‘sagging’, despite an upper denture made by a cosmetic dentist in Las Vegas (Fig. 1). Since then, he had seen numerous dentists, including several prominent prosthodontists, to resolve his smile, and more importantly, his facial concerns. However, the patient was not prepared to commit to extensive treatment plans, neither in time nor in finances; not to mention the pain and recovery period associated with the multiple surgeries he would have to undergo for a permanent solution. Among the numerous treatment options we discussed for his dental requirements were implants, a new denture, a precision partial, veneers, and crowns. He was then presented with an entirely innovative option he had not heard of before: a new full denture for the upper arch and a Snap-On Smile for the lower arch, to create the beautiful smile and natural facial dimensions for which he longed.

The DownPak device: Obturation with heat and vibration

February 18, 2009

Achieving successful endodontic treatment requires an accurate diagnosis and appropriate cleaning, shaping and three-dimensional obturation of the canals. This article describes a new obturation technique that utilizes a warm plugger or spreader, delivered in conjunction with vibration, with a single cordless device, the DownPak.

BioRaCe—Efficient, safe and biological based sequence files

February 18, 2009

Endodontics is the prevention or elimination of apical periodontitis. Apical periodontitis is caused by microbes in a necrotic pulp.1-3 If the pulp is vital, apical periodontitis of endodontic origin is not possible.4,5 Vital pulp therapy (operative dentistry or root treatment of a vital pulp) is considered prevention of apical periodontitis while the disinfection steps when treating a necrotic infected pulp is considered elimination of apical periodontitis.

The ProTaper technique: Shaping the future of endodontics

February 18, 2009

There are enormous differences in opinion regarding the best methods for shaping root canals. A review of the literature reveals virtually no agreement on a variety of fundamental clinical issues. There is ongoing controversy regarding the sequence of canal preparation, working length, and the use of patency files. There is vigorous debate related to the question of how large to prepare the apical foramen. There is no consensus regarding deep shape, or what is the appropriate percentage taper of a canal that ensures a root canal system can be both three-dimensionally cleaned and filled. There is confusion trying to identify and integrate the best technologies and instruments.

Evaluating instrumentation techniques

February 18, 2009

With the continuous introductions of endodontic rotary files, recommended techniques for their use seem to proliferate even more rapidly. Although a desired canal shape can be prepared with virtually any series of instruments, voices of advocates confuse the choices with differing and sometimes conflicting approaches for accomplishing that shape. One is inclined to ask, “Can they all be right?”
