Article Abstract
Purpose: This observational study introduces a novel digital technique for analyzing theinclination of the tooth emergence profile and the distance between the bone crest and thecementoenamel junction (CEJ), essential in prosthetic dentistry.
Material And Methods: Thestudy used cone-beam computed tomography (CBCT) scans from 24 patients, analyzing 57teeth for emergence profile inclination and 206 teeth for the bone crest-CEJ distance. Digitalmeasures were taken using an implant planning software.
Results: The emergence profileangle varies according to the tooth anatomy. Results indicated an increase in emergenceprofile angle from an average value of 13° to 19° when simulating prosthetic chamferpreparation, highlighting the importance of maintaining the natural tooth anatomy inrestorative procedures. The average distances between bone crest and CEJ were 2.43 ± 1.08mm on the buccal side, 1.96 ± 0.88 mm on the palatal side, 1.88 ± 1.05 mm on the mesialside, and 1.97 ± 0.92 mm on the distal side. Discrepancies in bone crest heights, particularlyat the vestibular reference point, were found, which could affect periodontal health.
Conclusion: The research provides a foundation for future studies to refine soft tissuemanagement techniques in dental practice. These findings underscore the needing for adeeper understanding of supracrestal tissues in prosthetic rehabilitation, aiming to enhancethe design of anatomical implant abutments and improve patient outcomes.

Giant cell tumor (GCT) of the bone, although benign, demonstrates local aggressiveness, a potential for recurrence, and, in rare instances, malignant transformation. Functional preservation is crucial in cases involving the articular surface, often utilizing the Sandwich Technique. We propose an enhanced reconstruction method using the inner table of the iliac crest in a reverse fashion, offering a more anatomically contoured proximal tibial plateau and reducing donor site morbidity compared to tricortical iliac crest grafting.

Breast, prostate and lung cancer cells frequently metastasize to bone, leading to disruption of the bone microstructure. This study utilized mechanical testing with micro-CT imaging, digital volume correlation (DVC), and atomic force microscopy (AFM) nanomechanical testing to examine the mechanical property variations in mouse long bones (tibia) with metastatic lung cancer cell involvement, spanning from the whole-bone scale to the microstructural level. In addition, we also investigated how metastatic invasion alters the morphology of hydroxyapatite nanocrystals in bone at the nanometer scale.

Recurrent anterior instability with glenoid bone loss is a difficult problem with several surgical options. The Latarjet technique remains the gold standard for glenoid bone reconstruction in the setting of critical glenoid bone loss with excellent long-term outcomes. However, this technique has well known downsides including high rates of complications.

This study aimed to characterize gingival thickness (GT) and determine correlations with other local phenotypic features. CBCT scans from adult subjects involving the maxillary anterior teeth were obtained to assess buccal GT at different apicocoronal levels, periodontal supracrestal tissue height (STH), the distance (CEJ-BC) from the cementoenamel junction (CEJ) to the alveolar bone crest (BC), and buccolingual tooth dimensions. A total of 100 subjects and 600 maxillary anterior teeth comprised the study sample.

Background: The extent to which excessive glenoid retroversion leads to increased glenohumeral contact pressures and whether these increases can be mitigated surgically is unknown.
Purpose: To evaluate the effect of excessive glenoid retroversion and posterior iliac crest bone grafting (ICBG) with or without glenoid osteotomy on glenohumeral contact patterns.
Study Design: Controlled laboratory study.
