Inadvertent tooth movement with fixed lingual retainers
Fixed retainers are effective in maintaining the alignment of the anterior teeth more than 90% of the time, but they can produce inadvertent tooth movement that in the most severe…
Evaluation of marginal alveolar bone in the anterior mandible with pretreatment and posttreatment computed tomography in nonextraction patients
Introduction Our objectives were to evaluate marginal alveolar bone height in the anterior mandible after orthodontic treatment and to assess any correlations between morphologic and treatment changes. Methods We used…
Progressive changes in patients with skeletal Class III malocclusion treated by 2-jaw surgery with minimal and conventional presurgical orthodontics: A comparative study
Introduction In this study, we aimed to compare treatment efficacy and postsurgical stability between minimal presurgical orthodontics and conventional presurgical orthodontics for patients with skeletal Class III malocclusion. Methods Forty…
Preoperative and postoperative examination of occlusal and maxillofacial changes after osteochondroma extirpation
A patient came with left-side temporomandibular arthralgia, limited mandibular opening, frontal facial asymmetry, and a significant anterolateral open bite. Severe alterations in the occlusal and maxillofacial anatomy resulted from an…
Evaluation of facial hard and soft tissue asymmetry using cone-beam computed tomography
Introduction The purposes of this study were to (1) evaluate facial asymmetry 3 dimensionally using cone-beam computed tomography (CBCT) and (2) compare the right and left facial hard and soft…
Dimensional accuracy of digital dental models from cone-beam computed tomography scans of alginate impressions according to time elapsed after the impressions
Introduction Our objective was to investigate the dimensional accuracy of digital dental models obtained from the cone-beam computed tomography (CBCT) scans of alginate impressions according to the time elapsed after…
Unexpected complications associated with mandibular fixed retainers: A retrospective study
Introduction The purposes of this retrospective study were to describe the types of unexpected complications associated with mandibular fixed retainers and to assess their prevalences and possible etiologic causes. Methods…
Skeletal anchorage in orthodontic treatment of Class II malocclusion: Contemporary applications of orthodontic implants, miniscrew implants and miniplates
Over the past decade, orthodontic skeletal anchorage devices have gained significant traction in the orthodontic community. These devices have become instrumental in vertical control of the dentition, anteroposterior movement of…
Bone density effects on the success rate of orthodontic microimplants evaluated with cone-beam computed tomography
Introduction The purpose of this study was to evaluate the effect of bone densities on the success rate of orthodontic microimplants with cone-beam computed tomography images. Methods We examined 127…
Correlation and linear regression
In the next series of articles, I will discuss correlation and linear regression. Correlation indicates whether there is any association between 2 quantitative variables and the strength of that association….
