Background: This study aimed to develop a classification for the sagittal root positioning (SRP) of mandibular anterior teeth in terms of their anterior buccal bone for use before placing immediate implants.
Methods: A retrospective review of CBCT images was conducted on 150 patients (75 males and 75 females; mean age: 47.5 years) who met the inclusion criteria. The root position of the tooth samples was classified as buccal, middle, or lingual types according to their respective sagittal position and subtypes a, b, c, or d, according to the morphology of their osseous housing.
Results: The frequencies of the root positions of each classified group of the sample teeth were as follows: 14% buccal type, 77% middle type, and 8% lingual type; 18.0% subtype a, 4.33% subtype b, 75.55% subtype c, and 2.11% subtype d. As a complementary procedure for data collection, the sagittal position of the apex was classified into Class I (buccally angulated apex: 4.6%), Class II (apex with no angulation: 78.2%), Class III (lingually angulated apex: 0.7%) and Class IV (exposed root: 16.3%). In addition, the results of the examination of the buccal undercut showed that in 1.6%, 32.0%, and 66.3% of the sample teeth, the undercut was located coronally, medially, and apically, respectively.
Conclusion: Considering these results, the newly proposed SRP classification system can be used to study the mandibular anterior buccal bone morphology as a diagnostic tool for immediate implant treatment.

Introduction: The dentoskeletal effects of clear aligner treatment (CAT) with Invisalign vs temporary skeletal anchorage device-anchored Sydney intrusion spring (SIS) were compared in consecutively treated growing patients with anterior open bite using cone-beam computed tomography scans.
Methods: Fifteen adolescents treated exclusively with Invisalign, and 14 with SIS (first-phase treatment) were assessed retrospectively. Rigid-wise, voxel-based registration of pretreatment and posttreatment cone-beam computed tomography scans were performed using the anterior cranial base, maxillary plane, and mandibular body as reference regions.

Introduction: Interproximal attachment has received much attention in modern periodontology because it is a key diagnostic and prognostic factor. Currently, we can find many articles with results of bare root coverage, but few data and studies that describe root closure and obtaining interproximal attachment at the same time.
Objectives: The purpose of this study is to introduce a double-layer tunnel surgical technique for gingival papilla reconstruction and regeneration of the supraalveolar interproximal attachment.

Introduction: This study aims to determine if intraoral 850 nm LED irradiation could reduce the duration of lower anterior crowding alignment.
Methods: In a parallel-designed, randomized controlled clinical trial 60 patients with 2 to 6 mm of lower incisor crowding who need non-extraction treatment, were randomly assigned to the intervention and control groups by block randomization (36 females, 24 males, mean age: 19.93 ± 3.
Jaw Growth and Development in Class II Division I Malocclusion Children Using the Myobrace® Muscle Function Appliance.

Aim: Class II Division I malocclusion is common in pediatric orthodontics, and is often associated with malocclusion and poor muscle functionality. However, research on post-treatment changes in maxillomandibular dimensions, excluding normal development influences, is limited. Therefore, this study aimed to investigate the effects of Myobrace® appliance and targeted muscle functional training on maxillomandibular dimensions in children with Class II Division I malocclusion, compared to directed oral muscle training alone.
