Using Orthodontic Intrusion of Abraded Incisors to Facilitate Restoration
Vincent G. Kokich, Sr., DDS, MSD;Lucien J. Bellamy, DMD, MSD, Jake A. Weissman
Background. The authors examined the effects of orthodontic intrusion of abraded incisors in adult patients to facilitate restoration, focusing specifically on changes in alveolar bone level and root length.
Methods. The authors analyzed records of 43 consecutive adult patients (mean age 45.9 years). They identified intrusion by means of cephalometric radiographs and bone level and root length by means of periapical radiographs. They calculated treatment differences from the pretreatment period to the posttreatment period.
Results. In general, bone level followed the tooth during intrusion, but a small amount of bone loss occurred (P < .0001). There were no significant associations with age, sex, treatment time, intrusion or pretreatment bone level. All intruded teeth exhibited significant root resorption during treatment (mean = 1.48 millimeters). However, the change was similar to that seen in incisors that were not intruded. There were no associations with age, sex, treatment time or intrusion, but there was a positive relationship between pretreatment root length and root resorption.
Conclusions and Clinical Implications. Incisor intrusion in adults moves the dentogingival complex apically and is a valuable adjunct to restorative treatment. Potential iatrogenic consequences of alveolar bone loss and root resorption are minimal and comparable with the consequences of other orthodontic tooth movements.
Adjunctive Orchestrated Orthodontic Therapy
The altruistic goal of any cosmetic dental rehabilitation is the re-establishment of a healthy maintainable aesthetic functional interface from an otherwise damaged dentition. To this end, a multi-disciplinary treatment plan is necessary to fulfill the periodontal, orthodontic, maxillofacial and cosmetic requirements for a healthy, stable dentition that has a favorable long-term prognosis. This comprehensive treatment approach strives for the constituent components of the dentition to have a proper…
Esthetics: The Orthodontic-Periodontic Restorative Connection
As we complete the 20th and progress into the 21st century, orthodontists worldwide are experiencing a gradual but significant change in their practices. The number of adult patients has increased substantially. Although adults cooperate better than adolescents, they present a different set of challenges for the orthodontist. Adults may have worn or abraded teeth, uneven gingival margins, missing papillae, and periodontal bone loss, all of which can jeopardize the esthetic appearance of the teeth…
Adjunctive Role of Orthodontic Therapy
Orthodontic tooth movement may be a substantial benefit to the adult periorestorative patient. Many adults who seek routine restorative dentistry have problems with tooth malposition that compromise their ability to clean and maintain their dentitions. If these individuals also are susceptible to periodontal disease, tooth malposition may be an exacerbating factor that could cause premature loss of specific teeth. Orthodontic appliances have become smaller, less noticeable, and easier to maintain…

The Goals of Orthodontic Treatment
A discussion on managing the outcome of orthodontic treatment.
Dr. Sperling examines the process of facial analysis in orthodontics.
Assessment and Treatment in Dentofacial Esthetics: A Comprehensive Global Perspective
Dr. Sarver will present a different system of esthetic classification which is made up of three major components: Macroesthetics (the facial appearance), Miniesthetics (the smile) and Miniesthetics (the teeth and gingival scaffold). We will cover a systematic analysis of the face, smile, and teeth and how they interact, adding a new and rewarding dimension to your approach to treatment planning and treatment outcomes.

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.
