Bull Tokyo Dent Coll. 2024 Feb 15. doi: 10.2209/tdcpublication.2023-0025. Online ahead of print.ABSTRACTThe present study investigated the cyclic fatigue properties of titanium alloys (Ti-6Al-4V and Ti-6Al-7Nb) as implant materials and compared their properties with those of commercially pure titanium. Ti-6Al-4V and Ti-6Al-7Nb cylinders with diameters of 3.0 mm were examined. The surfaces of the cylinders were roughened by sand blasting with alumina particles and acid etching. Static and cyclic tests were performed according to ISO 14801:2016. The yield force in the static test (YS) was measured in 5 specimens of each allo...

Entire Dental Arch Mesial Movement after Extraction of Maxillary Right Central Incisor due to Root Fracture Treated with Temporary Anchorage Devices
Bull Tokyo Dent Coll. 2024 Feb 15. doi: 10.2209/tdcpublication.2023-0017. Online ahead of print.ABSTRACTThis case report describes a 19-year-old woman with skeletal Class I crowding and an unsalvageable maxillary right central incisor. She visited our clinic with the chief complaint of mobility of the maxillary right central incisor due to a traffic accident. After extraction of the maxillary right central incisor, the space was closed orthodontically. All the maxillary right teeth were moved mesially with an elastic chain attached to a palatal lever arm which was connected to palatal temporary anchorage devices (TADs). Af...

Exploratory Study of Growth of Circumference of Mandibular Fossa Adjacent to Petrous Portion of Temporal Bone Using Dried Skulls
This study investigated the morphogenetic process of development during tooth eruption using dried skulls harvested from Indian donors. The average distance between the ala-major-squamosa suture and the foramen ovale according to age group was as follows: 3.24 mm in the 8-month-old group and 8.92 mm in the adult group. The average distance between the ala-major-squamosa suture and the apex of the articular tubercle according to age groups was as follows: 10.38 mm in the 8-month-old group and 19.34 mm in the adult group. The average distance between the point of intersection of the petrosquamous fissure and petrotympanic fi...

Periodontal Regenerative Therapy with Recombinant Human Fibroblast Growth Factor (rhFGF) -2 for Stage III Grade C Periodontitis: A Case Report with 6-month Follow-up
This report describes a case of generalized chronic periodontitis requiring periodontal regenerative therapy. The patient was a 56-year-old woman visiting the Tokyo Dental College Suidobashi Hospital with the chief complaint of swelling in the maxillary right gingiva. An initial examination revealed 34.0% of sites with a probing depth (PD) of ≥4 mm. The prevalence of sites with bleeding on probing was 32.7%. The plaque control record (PCR) score was 65.7%. Radiographic examination revealed angular bone resorption at #18 and 48. Horizontal absorption was also observed in other areas. The percent bone loss/age at #48 was 1...

Three-dimensional Maxillofacial Morphology Measurements in Japanese Adults with Normal Occlusion
This study aimed to collect 3D morphological data using CT images to establish new landmarks for analysis and diagnosis in orthodontic treatment. Twenty male and 20 female adult Japanese dry skulls with of normal occlusion were selected. The skulls were scanned using a multidetector helical CT system (SIEMENS, Volume Zoom Plus 4, Germany). Models were reconstructed using 3D measurement software (Simplant, Dentsply Sirona, Tokyo, Japan) and 45 landmarks determined. Three-dimensional measurement for a total of 30 items representing these landmarks was then performed. The results provided 3D standard values for maxillofacial ...

A Case Report of Periodontal Regenerative Therapy Using Recombinant Human Fibroblast Growth Factor 2 and Deproteinized Bovine Bone Mineral with Non-incised Papillae Surgical Approach (NIPSA) for Angular Bone Defect in Patient with Stage III Grade C Periodontitis
This report describes a case of Stage III Grade C periodontitis requiring periodontal regenerative therapy. The patient was a 19-year-old woman who presented with the chief complaint of gingival recession in the incisor region. An initial examination revealed that 45.3% of sites had a probing depth of ≥4 mm and 45.8% bleeding on probing. Radiographic examination showed angular bone resorption in #25, 26, 31, 36, and 46 and horizontal resorption in other regions. Initial periodontal therapy was implemented based on a clinical diagnosis of Stage III Grade C periodontitis (generalized aggressive periodontitis). Occlusal adj...

Treatment of Gingival Recession in Multiple Teeth Using Coronally Advanced Flap with Connective Tissue Graft: A Case Report
This report describes a case of gingival recession in multiple teeth with severe dentin hypersensitivity (DH) in which treatment included periodontal plastic surgery. The patient was a 34-year-old woman presenting with the chief complaint of DH at gingivalrecession sites. The patient had undergone orthodontic treatment when she was 30 years old. An initial examination revealed that none of the sites showed a probing depth of ≥4 mm and 21% of sites bleeding on probing. The clinical diagnosis was plaque-induced gingivitis. Teeth #14, 16, 23, 25, 26, 34, 35, 45, and 46 showed gingival recession ranging from 1 to 4 mm. Gingi...
