Two cases exhibiting upper incisor apical root resorption when using purely tipping movements with a fixed appliance technique are reported. Possible causes of resorption are discussed, but no definite factor was apparent in these cases.

Aim of the studyː to find if apical root resorption is related to orthodontic treatment time, type of appliance used and which are the most susceptible teeth to develop this type of resorption. Material and methodsː 70 patients (27 males and 43 females) selected from patients reffered for an orthodontic treatment at the Orthodontic Department of Faculty of Dentistry, University of Medicine and Pharmacy from TirguMures. The mean age at the beginning of treatment was 15.11 years for males and 14.67 years for females subjects. At the end of treatment, on their panormaic radiographs it was measured apical root resorption on incisors, premolars and molars in the upper and lower arch. Resultsː Root resorption was significantly (p< 0.05) correlated with fixed appliance treatment (49 percent). Patients with the longest treatment periods presented with significantly (p<0.05) more grade 2 resorptionː 28 months (± 2.6 SD) in the upper arch and 30 months (± 3.2 SD) in the lower arch. In the patients with the lowest treatment period (16 months in the maxilla and 18 months in the mandible arch) it was found no resorption. In the upper arch most of the patients (22.22 % males and 18.6% females) showed a grade 2 resorption in the incisor area. Root resorption of the premolars was seen in 18.5% of the male patients (7.4% with grade 2 ) and in 16.26 % of the female patients (6.97 with grade 2). Conclusionsː There is a high correlation between the orthodontic treatment time and apical root resorption. Most exposed to this process are incisors from bot, upper and lower arch. Less resorption was noticed in the premolar area.

This article addresses diagnostic parameters that should be assessed in the treatment of extraction sockets with dental implant placement by presenting three case reports that emphasize the relevance of the amount of remaining bone walls. Diagnosis was based on the analysis of clinical and radiographic parameters (e.g.: bone defect morphology, remaining bone volume, presence of infections on the receptor site). Case 1 presents a 5-wall defect in the maxillary right central incisor region with severe root resorption, which was treated with immediate implant placement. Cases 2 and 3 present, respectively, two- and three-wall bone defects that did not have indication for immediate implants. These cases were first submitted to a guided bone regeneration (GBR) procedure with bone graft biomaterial and membrane barriers, and the implants were installed in a second surgical procedure. The analysis of the preoperative periodontal condition of the adjacent teeth and bone defect morphology is extremely important because these factors determine the choice between immediate implant or GBR treatment followed by implant installation in a subsequent intervention.

This chapter reviews T-Scan use in Orthodontics, defines normal T-Scan recordings for orthodontically treated subjects versus untreated subjects, and explains T-Scan use in the case-finishing process. After orthodontic appliance removal changes in the occlusion result from “settling,” because teeth can move freely within the periodontium. Despite a post treatment, visually “perfect” Angle's Class I relationship, ideal occlusal contacts often do not result solely from tooth movement. Creating simultaneous and equal contacts following fixed appliance removal can be accomplished using T-Scan data to optimize the end-result occlusal contact pattern. The software's force distribution and timing indicators (the 2 and 3-Dimensional ForceViews, force percentage per tooth and arch half, the Center of Force, and the Occlusion and Disclusion Times) aid in obtaining an ideal occlusal force distribution during case-finishing. Several case reports highlight combining lingual orthodontic treatment with Orthognathic surgery, where each presented case utilized T-Scan data during active treatment and retention.
