The thickness of the palatal bone perpendicular to the palatal curvature at various angles in different skeletal facial patterns using cone beam computed tomography (CBCT) is of interest to dentists. Hence, three groups (hyper-divergent, normo-divergent and hypo-divergent) based on the Frankfort mandibular angle and sagittal slices were taken at three and six-millimeter intervals along the mid-palatal suture. Transversal lines were created between specific teeth and bone thickness was measured at angles ranging from -30° to +30°. Data shows that the maximum bone thickness occurred at the first premolar and between the first and second premolars, with greater thickness in hyper divergent subjects. The anterior palate provided the best bone support for orthodontic mini-implants, with the greatest bone height found at the first premolar and paramedian regions.

This study evaluated the influence of a customized healing abutment (CHA) placed on immediate implants. It also assessed bone ridge volume, keratinized mucosal collar, and postoperative pain. Thirty-one patients needing tooth extraction and immediate implant were selected.

This study aimed to histomorphometrically evaluate the effect of guided bone regeneration (GBR) and two implant surfaces on the thickness and height of newly formed bone in dehiscence defects around titanium implants. Three premolars and the first bilateral molar were extracted from ten adult mongrel dogs, and 40 buccal bone dehiscences measuring 5 mm in height and 4 mm in width were created using a University of North Carolina (UNC) periodontal probe to confirm the dimensions. Forty implants were randomly assigned to one of four groups: oxidized implant surfaces (OIS, n = 10), turned/machined implant surfaces (TIS, n = 10), OIS + GBR (n = 10), and TIS + GBR (n = 10).

Background: Choosing the appropriate implants for reconstruction in revision TKA is essential for long-term fixation. While cones and augments are routinely utilized to address tibial defects, the effect of augment location and size on the biomechanical stability of revision TKA constructs and the indications for the use of metaphyseal cones are not known.
Questions/purposes: Is the risk of cement-implant debonding of revision TKA constructs impacted by the thickness and location (medial versus bicompartmental) of tibial augments and the presence of metaphyseal cones during (1) a demanding daily activity like stair ascent and (2) torsional loads?
Methods: Under institutional review board approval, we developed patient-specific finite-element models of revision TKA from four patients (three males and one female, ages 50 to 80 years, BMI 27 to 37 kg/m2) who underwent two-stage revision and had a CT scan with no metal artifact after first-stage implant removal.

Sectionally nonlinearly functionally graded (SNFG) structures with triply periodic minimal surface (TPMS) are considered ideal for bone implants because they closely replicate the hierarchical, anisotropic, and porous architecture of natural bone. The smooth gradient in material distribution allows for optimal load transfer, reduced stress shielding, and enhanced bone ingrowth, while TPMS provides high mechanical strength-to-weight ratio and interconnected porosity for vascularization and tissue integration. Wherein, The SNFG structure contains sections with thickness that varies nonlinearly along their length in different patterns.

Background: The purpose of the study is to evaluate the use of a magnetodynamic instrument (Magnetic Mallet, Metaergonomica, Turbigo, Milan, Italy) to perform a horizontal bone expansion in edentulous sites that need to be rehabilitated with a dental implant.
Methods: A sample of 15 patients, 11 men and 4 women, age between 39 and 78 years, was analyzed. A total of 18 conical-shaped implants with a diameter of 3.
