Congenitally Missing Mandibular Second Premolars Congenitally Missing Mandibular Second Premolars

Summary:

Introduction: Congenital absence of mandibular second premolars affects many orthodontic patients. The orthodontist must make the proper decision at the appropriate time regarding management of the edentulous space. These spaces can be closed or left open. Implications: If the space will be left open for an eventual restoration, the keys during orthodontic treatment are to create the correct amount of space and to leave the alveolar ridge in an ideal condition for a future restoration. If the space will be closed, the clinician must avoid any detrimental alterations to the occlusion and the facial profile. Significance: Some early decisions that the orthodontist makes for a patient whose mandibular second premolars are congenitally missing will affect his or her dental health for a lifetime. Therefore, the correct decision must be made at the appropriate time. Purpose: In this article, we present and discuss various treatment alternatives for managing orthodontic patients with at least 1 congenitally missing mandibular second premolar.

Management of Complex Orthodontic Problems
Today implants are commonly used to replace missing teeth in partially edentulous adult orthodontic patients. Because these patients are missing teeth, orthodontic mechanics may be complicated or often impossible because of insufficient anchorage. In these situations, it may be feasible to use the implant initially as an orthodontic anchor to facilitate complex tooth movement and secondarily as an abutment for a crown or fixed prosthesis. This article will discuss the ramifications and requirements…

Effective Teaching Part 1
Today most orthodontists own a laptop computer that is equipped with PowerPoint (Microsoft Corporation) or some other type of presentation software. In addition, most orthodontists use a digital clinical camera with high resolution to gather photographic records of their patients before, during, and after orthodontic treatment. So any orthodontist has the capability to assemble a lecture or presentation for a group of dentists. What if you were invited to give a one-hour presentation about orthodontics…

Orthodontics vs Restorative Materials

Orthodontics vs Restorative Materials
Today's "cosmetically aware" adult patients are seeking out advice and opinions about oral/facial esthetics from dental professionals. Recently, many articles have been published about the "quick fixes" available in esthetic therapy. With the advent of next-generation restorative materials and the ability to predictably bond to remaining tooth structures, some authors advocate composite bonding or veneering of misaligned teeth, rather than orthodontic therapy. Composite bonding or veneering are…

Interdisciplinary Team Dentistry for Total Dentofacial Esthetics - Part 2
Orthodontics sets up the foundation for future prosthetics in cases with periodontal, surgical and restorative dentistry requirements. Adult orthodontics simplifies complex clinical situations. Making it easier for restorative dentist to achieve better esthetic & functional results. Orthognatic surgery combined with orthodontics corrects skeletal discrepancies in order to have the patient ready for prosthodontic replacement of multiple missing teeth. Cases combined with implants to restore form & function will further illustrate the importance of multidisciplinary dentistry. Today´s practice requires a team approach that will be presented. In order to meet the patient´s demands for better esthetics and to obtain long term occlusal stability of our results.

The Role of CBCT in the Evaluation of Alveolar Bone Premium Member Content

The Role of CBCT in the Evaluation of Alveolar Bone
While traditional 2D radiography has been said to show less than 50% of the anatomy of alveolar bone, the arrival of CBCT technology for practicing orthodontists has given practitioners the ability to completely view and study this area with respect to tooth movement. An update on the related research will introduce this topic with a specific emphasis on the accuracy, application and importance of this radiological advancement followed by the presenter's own protocols for patient diagnosis and treatment methods. Case presentations will be used throughout the lecture to highlight the clinical significance of using CBCT in Orthodontics to anticipate and assess the periodontal consequences of tooth movement.

Orthodontic Management of Impacted Teeth Premium Member Content

Orthodontic Management of Impacted Teeth
Over the last 25 years we have managed different clinical situations that include every tooth in the mouth that can be impacted on an orthodontic patient. We will focus the webinar both on mucogingival considerations as well as orthodontic biomechanics. Impacted teeth can be a challenge and can make a treatment last longer. We will show a logic approach to these situations. That produces good stability, periodontal health and relative short treatment time.
