Stability of tooth position in the broader sense considers all the forces that may act on the tooth. Reitan reported that significant forces remained in the periodontium after tooth movement, and he carried out research that demonstrated residual stretching of the crestal periodontal fibers more than 7 months after tooth movement. Brain demonstrated that severing the fibers reduced the relapse in tooth position in dogs. Edwards published a series of papers exploring the effects of surgical transection of the gingival fibers on tooth stability, recommending that circumferential fiberotomy be performed in order to increase posttreatment tooth stability. Other researchers have suggested ways to increase the stability of the incisors, which are typically most prone to relapse. Peck and Peck recommended that interproximal reduction be done to broaden the contact point. Boese also recommended interproximal reduction as part of a four-pronged approach to retention.

Background: Gingival recession defects (GRDs) pose functional and esthetic concerns and may be associated with unfavorable tooth positions. Surgically facilitated orthodontic treatment (SFOT) with clear aligners can be a valuable option for adults with severe malocclusion and GRDs.
Methods: A 28-year-old male presented with severe dental crowding, Class III dental malocclusion, localized tooth crossbites, and tapered maxillary arch.

Aim: The purpose of the study is to evaluate how well the Endovac system and conventional needle irrigation work to remove smear layers (SR) from primary teeth root canals.
Materials And Methods: Fifty extracted human primary teeth were divided into two equal sections vertically, then positioned within an acrylic model that was secured with screws. Group A (Endovac), = 25, and group B (traditional needle), = 25.

Center of Advanced Dental Education, Department of Periodontics, Saint Louis University, Saint Louis, Missouri, USA.
Objectives: To investigate the correlation between gingival thickness (GT) and buccal bone thickness (BBT), as well as the effects of GT, BBT, bone crest level (BC), and tooth position on the buccal gingival margin location of maxillary teeth in the esthetic zone.
Materials And Methods: Periodontally healthy subjects with prior cone beam computed tomography and intraoral scans for dental implant planning were included. The hard and soft tissue measurements were retrospectively analyzed digitally.

Purpose: We aimed to analyze the influence of different designs (inlay, onlay, and crown) on stress distribution and crack propagation in an endodontically treated cracked premolar.
Methods: Three-dimensional (3D) finite element analysis (FEA) was employed to model an endodontically treated cracked premolar with three different restorations (inlay, onlay, and crown). Six types of loadings (vertical loading of 600 N; hot thermal-600 N vertical coupling loading; cold thermal-600 N vertical coupling loading; oblique loading of 200 N; hot thermal-200 N oblique coupling loading; cold thermal-200 N oblique coupling loading) were applied to simulate the hot and cold food/beverages intake.

The reverse scan technique offers several advantages, such as improvements of accuracy and visibility of critical anatomical structures, minimizing chair time, and providing better patient comfort. This was a case report successfully employing the reverse scan technique. A 72-year-old male patient desired to restore his teeth in both jaws, as he experienced difficulty eating and had never worn dentures.
